Operating Segments See Note 24 of the Combined Notes to Consolidated Financial Statements for additional information on Exelon’s operating segments. Merger with Constellation Energy Group, Inc. On March 12, 2012, Exelon completed the merger contemplated by the Merger Agreement among Exelon, Bolt AcquisitionCorporation, a wholly owned subsidiary of Exelon (Merger Sub), and Constellation. As a result of that merger, Merger Sub was merged intoConstellation (the Initial Merger) and Constellation became a wholly owned subsidiary of Exelon. Following the completion of the InitialMerger, Exelon and Constellation completed a series of internal corporate organizational restructuring transactions. Constellation mergedwith and into Exelon, with Exelon continuing as the surviving corporation (the Upstream Merger). Simultaneously with the UpstreamMerger, Constellation’s interest in RF HoldCo LLC, which holds Constellation’s interest in BGE, was transferred to Exelon Energy DeliveryCompany, LLC, a wholly owned subsidiary of Exelon that also owns Exelon’s interests in ComEd and PECO. Following the UpstreamMerger and the transfer of RF HoldCo LLC, Exelon contributed to Generation certain subsidiaries, including those with generation andcustomer supply operations that were acquired from Constellation as a result of the Initial Merger and the Upstream Merger. See Note 4 ofthe Combined Notes to Consolidated Financial Statements for additional information on the Constellation transaction. Generation Generation, one of the largest competitive electric generation companies in the United States as measured by owned and contractedMW, physically delivers and markets power across multiple geographic regions through its customer-facing business, Constellation.Generation operates in well-developed energy markets and employs an integrated hedging strategy to manage commodity price volatility. Itsgeneration fleet, including its nuclear plants which consistently operate at high capacity factors, also provide geographic and supply sourcediversity. These factors help Generation mitigate the current challenging conditions in competitive energy markets. Generation operates asan integrated business, leveraging its owned and contracted electric generation capacity to market and sell power to wholesale and retailcustomers. Generation’s customers include distribution utilities, municipalities, cooperatives, financial institutions, and commercial,industrial, governmental, and residential customers in competitive markets. Generation also sells natural gas and renewable energy andother energy-related products and services, and engages in natural gas exploration and production activities. Generation is a public utility under the Federal Power Act and is subject to FERC’s exclusive ratemaking jurisdiction over wholesalesales of electricity and the transmission of electricity in interstate commerce. Under the Federal Power Act, FERC has the authority to grantor deny market-based rates for sales of energy, capacity and ancillary services to ensure that such sales are just and reasonable. FERC’sjurisdiction over ratemaking also includes the authority to suspend the market-based rates of utilities (including Generation, which is a publicutility as FERC defines that term) and set cost-based rates should FERC find that its previous grant of market-based rates authority is nolonger just and reasonable. Other matters subject to FERC jurisdiction include, but are not limited to, third-party financings; review ofmergers; dispositions of jurisdictional facilities and acquisitions of securities of 7Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Additionally, ERCOT is not subject to regulation by FERC but performs a similar function in Texas to that performed by RTOs inmarkets regulated by FERC. Specific operations of Generation are also subject to the jurisdiction of various other Federal, state, regional andlocal agencies, including the NRC and Federal and state environmental protection agencies. Additionally, Generation is subject to mandatoryreliability standards promulgated by the NERC, with the approval of FERC. RTOs and ISOs exist in a number of regions to provide transmission service across multiple transmission systems. PJM, MISO,ISO-NE and SPP, have been approved by FERC as RTOs, and CAISO and ISO-NY have been approved as ISOs. These entities areresponsible for regional planning, managing transmission congestion, developing wholesale markets for energy and capacity, maintainingreliability, market monitoring, the scheduling of physical power sales brokered through ICE and NYMEX and the elimination or reduction ofredundant transmission charges imposed by multiple transmission providers when wholesale customers take transmission service acrossseveral transmission systems. Significant Acquisitions Antelope Valley Solar Ranch One. On September 30, 2011, Exelon announced the completion of its acquisition of all of the interestsin Antelope Valley, a 230-MW solar photovoltaic (PV) project under development in northern Los Angeles County, California, from FirstSolar, Inc., which is developing, building, operating, and maintaining the project. The first portion of the project began operations inDecember 2012, with six additional blocks coming online in 2013. Exelon has been informed by First Solar of issues relating to delays in thecertification of certain components relating to the final two blocks of the project, which will delay commercial operation of these two blocksuntil the first half of 2014. The delay will not have a material financial effect on Exelon. Exelon expects the project to be in full commercialoperation in the first half of 2014. The acquisition supports the Exelon commitment to renewable energy as part of Exelon 2020. The projecthas a 25-year PPA, approved by the CPUC, with Pacific Gas & Electric Company for the full output of the plant. Upon completion, the facilitywill add 230 MWs to Generation’s renewable generation fleet. Total capitalized costs for the facility are expected to be approximately $1.1billion. Total capitalized costs incurred through December 31, 2013 were approximately $968 million. Wolf Hollow Generating Station. On August 24, 2011, Generation completed the acquisition of all of the equity interests of WolfHollow, LLC (Wolf Hollow), a combined-cycle natural gas-fired power plant in north Texas, for a purchase price of $311 million whichincreased Generation’s owned capacity within the ERCOT power market by 720 MWs. See Note 4 of the Combined Notes to Consolidated Financial Statements for additional information on the above acquisitions. Significant Dispositions Maryland Clean Coal Stations. On November 30, 2012, a subsidiary of Generation sold the Brandon Shores generating station andH.A. Wagner generating station in Anne Arundel County, Maryland, and the C.P. Crane generating station in Baltimore County, Maryland toRaven Power Holdings LLC, a subsidiary of Riverstone Holdings LLC to comply with certain of the regulatory approvals required by themerger, for net proceeds of approximately $371 million, which resulted in a pre-tax loss of $272 million.

Generation, with the exception of the two units at Salem, which are operated by PSEG Nuclear, LLC (PSEG Nuclear), an indirect, whollyowned subsidiary of PSEG. In 2013 and 2012, electric supply (in GWh) generated from the nuclear generating facilities was 57% and 53%,respectively, of Generation’s total electric supply, which also includes fossil, hydroelectric and renewable generation and electric supplypurchased for resale. The majority of this output was dispatched to support Generation’s wholesale and retail power marketing activities. SeeITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS for furtherdiscussion of Generation’s electric supply sources. Constellation Energy Nuclear Group, Inc. Generation also owns a 50.01% interest in CENG, a joint venture with EDF. CENG is governed by a board of ten directors, five ofwhich are appointed by Generation and five by EDF. CENG owns and operates a total of five nuclear generating facilities on three sites,Calvert Cliffs, Ginna and Nine Mile Point. CENG’s ownership share in the total capacity of these units is 3,998 MW. See ITEM 2.PROPERTIES for additional information on these sites. On July 29, 2013, Exelon, Generation and subsidiaries of Generation entered into a Master Agreement with EDF, EDF Inc. (EDFI) (asubsidiary of EDF) and CENG. The Master Agreement contemplates that the parties will execute a series of additional agreements at aclosing that will occur following the receipt of regulatory approvals and the satisfaction of other customary closing conditions. Exelon currentlyexpects that the closing will occur early in the second quarter of 2014. At the closing, Generation, CENG and subsidiaries of CENG will execute a Nuclear Operating Services Agreement pursuant to whichGeneration will operate the CENG nuclear generation fleet owned by CENG subsidiaries and provide corporate and administrative servicesfor the remaining life of the CENG nuclear plants as if they were a part of the Generation nuclear fleet, subject to EDFI’s rights as a memberof CENG. CENG will reimburse Generation for its direct and allocated costs for such services. The Nuclear Operating Services Agreementwill replace the SSA. At the closing, Nine Mile Point Nuclear Station, a subsidiary of CENG, will also assign to Generation its obligations asOperator of Nine Mile Point Unit 2 under an operating agreement with the co-owner. In addition, at the closing the PSAA will be amendedand extended until the complete and permanent cessation of operation of the CENG generation plants. At closing, Generation will make a $400 million loan to CENG bearing interest at 5.25% per annum, payable out of specified availablecash flows of CENG and, in any event, payable upon settlement of the Put Option Agreement discussed below, if the put option is exercised,or payable upon the maturity date of the note (which will be 20 years from the closing), whichever occurs first. Immediately following receiptof the proceeds of such loan, CENG will make a $400 million special distribution to EDFI. The parties will also execute a Fourth Amendedand Restated Operating Agreement for CENG, pursuant to which, among other things, CENG will commit to make preferred distributions toGeneration (after repayment of the $400 million loan) quarterly out of specified available cash flows, until Generation has received aggregatedistributions of $400 million plus a return of 8.5% per annum from the date of the special distribution to EDFI. Generation and EDFI will also enter into a Put Option Agreement at closing pursuant to which EDFI will have the option, exercisablebeginning in 2016 and thereafter until June 30, 2022, to sell its 49.99% interest in CENG to Generation for a fair market value pricedetermined by agreement of the parties, or absent agreement, a third party arbitration process. The appraisers determining fair market valueof EDF’s 49.99% interest in CENG under the Put Option Agreement are instructed to take into account all rights and obligations under theCENG Operating Agreement, including Generation’s rights with respect to any unpaid aggregate preferred distributions and the relatedreturn, and the value of Generation’s rights to other distributions. The beginning of the exercise period will be accelerated if 10Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Exelon’s affiliates cease to own a majority of CENG and exercise a related right to terminate the Nuclear Operating Services Agreement. Inaddition, under limited circumstances, the period for exercise of the put option may be extended for 18 months. Generation will execute an Indemnity Agreement pursuant to which Generation will indemnify EDF and its affiliates against third partyclaims that may arise from any future nuclear incident (as defined in the Price Anderson Act) in connection with the CENG nuclear plants ortheir operations. Exelon will guarantee Generation’s obligations under this indemnity. CENG owns 100% of four nuclear units in Maryland and New York and 82% of Nine Mile Point Unit 2 in New York. Generationcurrently has an agreement under which it is purchasing 85% of the nuclear plant output owned by CENG that is not sold to third partiesunder pre-existing firm and unit contingent PPAs through 2014. Beginning on January 1, 2015 and continuing to the end of the life of therespective plants, Generation will purchase on a unit contingent basis 50.01% of the nuclear plant output owned by CENG, and EDF willpurchase on a unit contingent basis 49.99% of the nuclear plant output owned by CENG (EDF PPA). This agreement will continue to beeffective and is not affected by the Master Agreement, except that if the put option under the Master Agreement is exercised, then the EDFPPA would transfer to Generation upon the completion of the Put Option Agreement transaction. Currently, Exelon and Generation account for its investment in CENG under the equity method of accounting. The transfer of theoperational control to Exelon and Generation will result in Exelon and Generation being required to consolidate the financial position andresults of operations of CENG. When that accounting change occurs, Exelon and Generation will derecognize its equity method investmentin CENG and will record all assets, liabilities and the non-controlling interest in CENG at fair value on Exelon and Generation’s balancesheets. Any difference between the former carrying value and newly recorded fair value at that date will be recognized as a gain or loss uponconsolidation, which could be material to Exelon’s and Generation’s results of operations. See Note 5—Investment in CENG of theCombined Notes to Consolidated Financial Statements for additional information regarding CENG. Nuclear Operations. Capacity factors, which are significantly affected by the number and duration of refueling and non-refuelingoutages, can have a significant impact on Generation’s results of operations. As the largest generator of nuclear power in the United States,Generation can negotiate favorable terms for the materials and services that its business requires. Generation’s operations from its nuclearplants have historically had minimal environmental impact and the plants have a safe operating history. During 2013 and 2012, the nuclear generating facilities operated by Generation achieved capacity factors of 94.1% and 92.7%,respectively. Generation manages its scheduled refueling outages to minimize their duration and to maintain high nuclear generatingcapacity factors, resulting in a stable generation base for Generation’s wholesale and retail marketing and trading activities. During scheduledrefueling outages, Generation performs maintenance and equipment upgrades in order to minimize the occurrence of unplanned outagesand to maintain safe, reliable operations. In addition to the rigorous 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 hasextensive safety systems in place to protect the plant, personnel and surrounding area in the unlikely event of an accident. Regulation of Nuclear Power Generation. Generation is subject to the jurisdiction of the NRC with respect to the operation of itsnuclear generating stations, including the licensing for operation of each unit. The NRC subjects nuclear generating stations to continuingreview and regulation covering, among other things, operations, maintenance, emergency planning, security and environmental andradiological aspects of those stations. As part of its reactor oversight process, the NRC continuously 11Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. assesses unit performance indicators and inspection results, and communicates its assessment on a semi-annual basis. As ofDecember 31, 2013, the NRC categorized Dresden units 2 and 3, LaSalle unit 2, and Clinton in the Regulatory Response Column, whichis the second highest of five performance bands. All other units operated by Generation are categorized in the Licensee Response Column asof December 31, 2013, which is the highest performance band. On January 1, 2014, Dresden units 2 and 3 returned to the LicenseeResponse Column. The NRC may modify, suspend or revoke operating licenses and impose civil penalties for failure to comply with theAtomic Energy Act, the regulations under such Act or the terms of the operating licenses. Changes in regulations by the NRC may require asubstantial increase in capital expenditures for nuclear generating facilities and/or increased operating costs of nuclear generating units. On March 11, 2011, Japan experienced a 9.0 magnitude earthquake and ensuing tsunami that seriously damaged the nuclear units atthe Fukushima Daiichi Nuclear Power Station, which are operated by Tokyo Electric Power Co. In July 2011, an NRC Task Force formed inthe aftermath of the Fukushima Daiichi events issued a report of its review of the accident, including recommendations for future regulatoryaction by the NRC to be taken in the near and longer term. The Task Force’s report concluded that nuclear reactors in the United States areoperating safely and do not present an imminent risk to public health and safety. The NRC and its staff have issued orders andimplementation guidance for commercial reactor licensees operating in the United States. The NRC and its staff are continuing to evaluateadditional requirements. For additional information on the NRC actions related to the Japan Earthquake and Tsunami and the industry’sresponse, see ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OFOPERATIONS—Executive Overview. Licenses. Generation has 40-year operating licenses from the NRC for each of its nuclear units and has received 20-year operatinglicense renewals for Peach Bottom Units 2 and 3, Dresden Units 2 and 3, Quad Cities Units 1 and 2, Oyster Creek and Three Mile IslandUnit 1. Additionally, PSEG has 40-year operating licenses from the NRC and has received 20-year operating license renewals for SalemUnits 1 and 2. On December 8, 2010, Exelon announced that Generation will permanently cease generation operations at Oyster Creek byDecember 31, 2019. The following table summarizes the current operating license expiration dates for Generation’s nuclear facilities inservice: Station Unit In-ServiceDate Current LicenseExpiration Braidwood 1 1988 2026 2 1988 2027 Byron 1 1985 2024 2 1987 2026 Clinton 1 1987 2026 Dresden 2 1970 2029 3 1971 2031 LaSalle 1 1984 2022 2 1984 2023 Limerick 1 1986 2024 2 1990 2029 Oyster Creek 1 1969 2029 Peach Bottom 2 1974 2033 3 1974 2034 Quad Cities 1 1973 2032 2 1973 2032 Salem 1 1977 2036 2 1981 2040 Three Mile Island 1 1974 2034 12 (a)(b)(b) (c)(d) (c)(e) (c) (c) (c) (c)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Generation expects to apply for and obtain approval of license renewals for the remaining nuclear units. The operating license renewalprocess takes approximately four to five years from the commencement of the renewal process until completion of the NRC’s review. TheNRC review process takes approximately two years from the docketing of an application. Each requested license renewal is expected to be for20 years beyond the original license expiration. Depreciation provisions are based on the estimated useful lives of the stations, which reflectthe actual and assumed renewal of operating licenses for all of Generation’s operating nuclear generating stations except for Oyster Creek. In August 2012, Generation entered into an operating services agreement with the Omaha Public Power District (OPPD) to provideoperational and managerial support services for the Fort Calhoun Station and a licensing agreement for use of the Exelon NuclearManagement Model. The terms for both agreements are 20 years. OPPD will continue to own the plant and remain the NRC licensee. Nuclear Uprate Program. Generation is engaged in individual projects as part of a planned power uprate program across its nuclearfleet. When economically viable, the projects take advantage of new production and measurement technologies, new materials andapplication of expertise gained from a half-century of nuclear power operations. Based on ongoing reviews, the nuclear uprateimplementation plan was adjusted during 2013 to cancel certain projects. The Measurement Uncertainty Recapture uprate projects at theDresden and Quad Cities nuclear stations were cancelled as a result of the cost of additional plant modifications identified during final designwork which, when combined with then current market conditions, made the projects not economically viable. Additionally, the marketconditions prompted Generation to cancel the previously deferred extended power uprate projects at the LaSalle and Limerick nuclearstations. During 2013, Generation recorded a pre-tax charge to operating and maintenance expense and interest expense of approximately$111 million and $8 million, respectively, to accrue remaining costs and reverse the previously capitalized costs. Under the nuclear uprate program, Generation has placed into service projects representing 316 MWs of new nuclear generation at acost of $952 million, which has been capitalized to property, plant and equipment on Exelon’s and Generation’s consolidated balance sheets.At December 31, 2013, Generation has capitalized $203 million to construction work in progress within property, plant and equipment fornuclear uprate projects expected to be placed in service by the end of 2016, consisting of 200 MWs of new nuclear generation, that are in theinstallation phase across four nuclear stations; Peach Bottom in Pennsylvania and Byron, Braidwood and Dresden in Illinois. The remainingspend associated with these projects is expected to be approximately $300 million through the end of 2016. Generation believes that it isprobable that these projects will be completed. If a project is expected not to be completed as planned, previously capitalized costs will bereversed through earnings as a charge to operating and maintenance expense and interest. Nuclear Waste Disposal. There are no facilities for the reprocessing or permanent disposal of SNF currently in operation in theUnited States, nor has the NRC licensed any such facilities. Generation currently stores all SNF generated by its nuclear generating facilitiesin on-site storage pools or in dry cask storage facilities. Since Generation’s SNF storage pools generally do not have sufficient storagecapacity for the life of the respective plant, Generation has developed dry cask storage facilities to support operations. 13Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. As of December 31, 2013, Generation had approximately 59,900 SNF assemblies (14,400 tons) stored on site in SNF pools or drycask storage (this includes SNF assemblies at Zion Station, for which Generation retains ownership even though the responsibility fordecommissioning Zion Station has been assumed by another party; see Note 15 of the Combined Notes to Consolidated FinancialStatements for additional information regarding Zion Station Decommissioning). All currently operating Generation-owned nuclear sites haveon-site dry cask storage, except for Clinton and Three Mile Island. Clinton and Three Mile Island will currently lose full core reserve, which iswhen the on-site storage pool will no longer have sufficient space to receive a full complement of fuel from the reactor core, in 2015 and2023, respectively. Dry cask storage will be in operation at Clinton and is expected to be in operation at Three Mile Island prior to the closingof their respective on-site storage pools. On-site dry cask storage in concert with on-site storage pools will be capable of meeting all currentand 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 22 of the CombinedNotes to Consolidated Financial Statements. As a by-product of their operations, nuclear generating units produce LLRW. LLRW is accumulated at each generating station andpermanently disposed of at licensed disposal facilities. The Federal Low-Level Radioactive Waste Policy Act of 1980 provides that states mayenter 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 tobe operational until after 2020. Generation is currently utilizing on-site storage capacity at its nuclear generation stations for limited amounts of LLRW and has beenshipping its Class A LLRW, which represent 93% of LLRW generated at its stations, to disposal facilities in Utah and South Carolina. Thedisposal facility in South Carolina at present is only receiving LLRW from LLRW generators in South Carolina, New Jersey (which includesOyster Creek and Salem), and Connecticut. Generation has received NRC approval for its Peach Bottom and LaSalle stations that will allowstorage at these sites of LLRW from its remaining stations with limited capacity. Generation now has enough storage capacity to store allClass B and C LLRW for the life of all stations in Generation’s nuclear fleet. During 2012, Generation entered into a six year contract to shipClass B and Class C LLRW to Texas. The terms of the agreement will provide for disposal of all current Class B and Class C LLRW storedat the stations, as well as the waste generated during the term of the agreement. Although Texas started accepting waste for disposal in 2012,the Texas site is curie limited (3.9 million curies for 15 years). With this limit, the annual facility volume will not match industry production ofactivated hardware, and on-site storage is expected to be required for the Generation boiling water reactors. Generation continues to pursuealternative disposal strategies for LLRW, including an LLRW reduction program to minimize cost impacts and on-site storage. Nuclear Insurance. Generation is subject to liability, property damage and other risks associated with major incidents at any of itsnuclear stations, including the CENG nuclear stations. Generation has reduced its financial exposure to these risks through insurance andother industry risk-sharing provisions. See “Nuclear Insurance” within Note 22 of the Combined Notes to Consolidated Financial Statementsfor details. For information regarding property insurance, see ITEM 2. PROPERTIES—Generation. Generation is self-insured to the extent thatany losses may exceed the amount of insurance maintained or are within the policy deductible for its insured losses. Such losses could havea material adverse effect on Exelon’s and Generation’s financial condition and results of operations. 14Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Decommissioning. NRC regulations require that licensees of nuclear generating facilities demonstrate reasonable assurance thatfunds will be available in specified minimum amounts at the end of the life of the facility to decommission the facility. See ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—ExelonCorporation, Executive Overview; ITEM 7.

Dresden Unit 1 and Peach Bottom Unit 1 have ceased power generation. SNF at Dresden Unit 1 is currently being stored in dry caskstorage until a permanent repository under the NWPA is completed. All SNF for Peach Bottom Unit 1, which ceased operation in 1974, hasbeen removed from the site and the SNF pool is drained and decontaminated. Generation’s estimated ARO liability to decommissionDresden Unit 1 and Peach Bottom Unit 1 as of December 31, 2013 was $208 million and $114 million, respectively. As of December 31,2013, NDT funds set aside to pay for these obligations were $436 million. Zion Station Decommissioning. On December 11, 2007, Generation entered into an Asset Sale Agreement (ASA) withEnergySolutions, Inc. and its wholly owned subsidiaries, EnergySolutions, LLC (EnergySolutions) and ZionSolutions, LLC (ZionSolutions)under which ZionSolutions assumed responsibility for decommissioning Zion Station, which is located in Zion, Illinois and ceased operationin 1998. On September 1, 2010, Generation and EnergySolutions completed the transactions contemplated by the ASA. Specifically,Generation transferred to ZionSolutions substantially all of the assets (other than land) associated with Zion Station, including assets held inrelated NDT funds. In consideration for Generation’s transfer of those assets, ZionSolutions assumed decommissioning and other liabilities,excluding the obligation to dispose of SNF, associated with Zion Station. Pursuant to the ASA, ZionSolutions will periodically requestreimbursement from the Zion Station-related NDT funds for costs incurred related to the decommissioning efforts at Zion Station. However,ZionSolutions is subject to certain restrictions on its ability to request reimbursement; specifically, if certain milestones as defined in the ASAare not met, all or a portion of requested reimbursements shall be deferred until such milestones are met. See Note 15 of the CombinedNotes to Consolidated Financial Statements for additional information regarding Zion Station Decommissioning and see Note 2 of theCombined Notes to Consolidated Financial Statements for a discussion of variable interest entity considerations related to ZionSolutions. Fossil and Renewable Facilities (including Hydroelectric) Generation has ownership interests in 15,875 MW of capacity in fossil and renewable generating facilities currently in service.Generation wholly owns all of its fossil and renewable generating stations, with the exception of: (1) jointly owned facilities that includeKeystone, Conemaugh, and Wyman; (2) ownership interests through equity method investments in Colver, Malacha, Safe Harbor, andSunnyside; and (3) certain wind project entities with minority interest owners, see Note 2 of the Combined Notes to Consolidated FinancialStatements for additional information on these wind project entities. Generation’s fossil and renewable generating stations are all operated byGeneration, with the exception of Colver, Conemaugh, Keystone, LaPorte, Malacha, Safe Harbor, Sunnyside and Wyman, which areoperated by third parties. In 2013 and 2012, electric supply (in GWh) generated from owned fossil and renewable generating facilities was15% and 12%, respectively, of Generation’s total electric supply. The majority of this output was dispatched to support Generation’swholesale and retail power 15Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

PROPERTIES—Generationand ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—Exelon Corporation, Executive Overview for additional information on Generation Renewable Development. 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 navigablewaterways or Federal lands, or connected to the interstate electric grid. On August 29, 2012 and August 30, 2012, Generation submittedhydroelectric license applications to the FERC for 46-year licenses for the Muddy Run Pumped Storage Project and the ConowingoHydroelectric Project, respectively. Based on the latest FERC procedural schedule, the FERC licensing process is not expected to becompleted prior to the expiration of Muddy Run’s current license on August 31, 2014, and the expiration of Conowingo’s license onSeptember 1, 2014. However, the stations will continue to operate under annual licenses until FERC takes action on the 46-year licenseapplications. Refer to Note 3—Regulatory Matters for additional information. Insurance. Generation maintains business interruption insurance for its renewable projects, and delay in start-up insurance for itsrenewable projects currently under construction. Generation does not purchase business interruption insurance for its wholly owned fossiland hydroelectric operations. Generation maintains both property damage and liability insurance. For property damage and liability claims forthese operations, Generation is self-insured to the extent that losses are within the policy deductible or exceed the amount of insurancemaintained. Such losses could have a material adverse effect on Exelon’s and Generation’s financial condition and their results of operationsand cash flows. For information regarding property insurance, see ITEM 2. PROPERTIES—Generation. Long-Term Power Purchase Contracts In addition to energy produced by owned generation assets, Generation sources electricity and other related output from plants it doesnot own under long-term contracts.

See Note 25 of the Combined Notes to Consolidated Financial Statements for additional information. The fuel costs for nuclear generation are less than those for fossil-fuel generation. Consequently, nuclear generation is generally themost cost-effective way for Generation to meet its wholesale and retail load servicing requirements. The cycle of production and utilization of nuclear fuel includes the mining and milling of uranium ore into uranium concentrates, theconversion of uranium concentrates to uranium hexafluoride, the enrichment of the uranium hexafluoride and the fabrication of fuelassemblies. Generation has uranium concentrate inventory and supply contracts sufficient to meet all of its uranium concentraterequirements through 2016. Generation’s contracted conversion services are sufficient to meet all of its uranium conversion requirementsthrough 2020. All of Generation’s enrichment requirements have been contracted through 2018. Contracts for fuel fabrication have beenobtained through 2018. Generation does not anticipate difficulty in obtaining the necessary uranium concentrates or conversion, enrichmentor 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 aremanaged so that in the winter months sufficient volumes of fuel are available in the event of extreme weather conditions and during theremaining months to take advantage of favorable market pricing. Generation uses financial instruments to mitigate price risk associated with certain commodity price exposures. Generation alsohedges forward price risk, 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 AccountingPolicies and Estimates and Note 12 of the Combined Notes to Consolidated Financial Statements for additional information regardingderivative financial instruments. Power Marketing Generation’s integrated business operations include the physical delivery and marketing of power obtained through its generationcapacity and through long-term, intermediate-term and short-term contracts. Generation maintains an effective supply strategy throughownership of generation assets and power purchase and lease agreements. Generation has also contracted for access to additionalgeneration through bilateral long-term PPAs. PPAs are commitments related to power generation of specific generation plants and/or aredispatchable in nature similar to asset ownership depending on the type of underlying asset.

Past financial performance is no guarantee of future results. plan, with objectives such as obtaining low-cost energy supply sources to meet its physical delivery obligations to both wholesale and retailcustomers and assisting customers to meet renewable portfolio standards. Generation may buy power to meet the energy demand of itscustomers, including ComEd, PECO and BGE. Generation sells electricity, natural gas, and related products and solutions to variouscustomers, including distribution utilities, municipalities, cooperatives, and commercial, industrial, governmental, and residentialcustomers in competitive markets. Generation’s customer facing operations combine a unified sales force with a customer-centric model thatleverages technology to broaden the range of products and solutions offered, which Generation believes promotes stronger customerrelationships. This model focuses on efficiency and cost reduction, which provides a platform that is scalable and able to capitalize onopportunities for future growth. Generation’s purchases may be for more than the energy demanded by Generation’s customers. Generation then sells this openposition, along with capacity not used to meet customer demand, in the wholesale electricity markets. Where necessary, Generation alsopurchases transmission service to ensure that it has reliable transmission capacity to physically move its power supplies to meet customerdelivery needs in markets without an organized RTO. Generation also incorporates contingencies into its planning for extreme weatherconditions, including potentially reserving capacity to meet summer loads at levels representative of warmer-than-normal weather conditions.Generation actively manages these physical and contractual assets in order to derive incremental value. Additionally, Generation is involvedin the development, exploration, and harvesting of oil, natural gas and natural gas liquids properties. Price Supply Risk Management Generation also manages the price and supply risks for energy and fuel associated with generation assets and the risks of powermarketing activities. Generation implements a three-year ratable sales plan to align its hedging strategy with its financial objectives.Generation also enters into transactions that are outside of this ratable sales plan. Generation is exposed to relatively greater commodityprice risk in 2014 and beyond for which a larger portion of its electricity portfolio may be unhedged. Generation has been and will continue tobe proactive in using hedging strategies to mitigate this risk in subsequent years. As of December 31, 2013, the percentage of expectedgeneration hedged for the major reportable segments was 92%-95%, 62%-65% and 30%-33% for 2014, 2015, and 2016, respectively. Thepercentage of expected generation hedged is the amount of equivalent sales divided by the expected generation. Expected generationrepresents the amount of energy estimated to be generated or purchased through owned or contracted capacity, including purchased powerfrom CENG. Equivalent sales represent all hedging products, which include economic hedges and certain non-derivative contracts, includingsales to ComEd, PECO and BGE to serve their retail load. A portion of Generation’s hedging strategy may be implemented through the useof fuel products based on assumed correlations between power and fuel prices, which routinely change in the market. Generation also usesfinancial and commodity contracts for proprietary trading purposes, but this activity accounts for only a small portion of Generation’s efforts.The trading portfolio is subject to a risk management policy that includes stringent risk management limits, including volume, stop-loss andvalue-at-risk limits, to manage exposure to market risk. Additionally, the corporate risk management group and Exelon’s RMC monitor thefinancial risks of the wholesale and retail power marketing activities. See ITEM 7A.

At December 31, 2013, Generation’s short and long-term commitments relating to the purchase of energy and capacity from and tounaffiliated utilities and others were as follows: (in millions) Net CapacityPurchases RECPurchases Transmission RightsPurchases Purchased Energyfrom CENG Total 2014 $412 $117 $25 $824 $1,378 2015 367 110 13 — 490 2016 284 76 2 — 362 2017 223 25 2 — 250 2018 112 3 2 — 117 Thereafter 414 3 32 — 449 Total $1,812 $334 $76 $824 $3,046 (a)Net capacity purchases include PPAs and other capacity contracts including those that are accounted for as operating leases. Amounts presented in the commitmentsrepresent Generation’s expected payments under these arrangements at December 31, 2013, net of fixed capacity payments expected to be received by Generationunder contracts to resell such acquired capacity to third parties under long-term capacity sale contracts. Expected payments include certain fixed capacity chargeswhich may be reduced on plant availability.(b)The table excludes renewable energy purchases that are contingent in nature.(c)Transmission rights purchases include estimated commitments for additional transmission rights that will be required to fulfill firm sales contracts. As part of reaching a comprehensive agreement with EDF in October 2010, the existing power purchase agreements with CENG weremodified to be unit-contingent through the end of their original term in 2014. Under these agreements Generation purchases 85% of thenuclear plant output owned by CENG that is not sold to third parties. CENG has the ability to fix the energy price on a forward basis byentering into monthly energy hedge transactions for a portion of the future sale, while any unhedged portions will be provided at marketprices by default. Additionally, beginning in 2015 and continuing to the end of the life of the respective plants, Generation agreed to purchase50.01% of the nuclear plant output owned by CENG at market prices. This purchase agreement will continue to be effective under the MasterAgreement discussed above, except that if the put option under the Master Agreement is exercised, then the EDF PPA will be transferred toGeneration upon the completion of the Put Option Agreement transaction. Generation discloses in the table above commitments to purchasefrom CENG at fixed prices. All commitments to purchase from CENG at market prices, which include all purchases subsequent toDecember 31, 2014, are excluded from the table. Generation continues to own a 50.01% membership interest in CENG that is accounted foras an equity method investment. See Note 25 of the Combined Notes to Consolidated Financial Statements for more details on thisarrangement. Capital Expenditures Generation’s business is capital intensive and requires significant investments in nuclear fuel and energy generation assets and inother internal infrastructure projects. Generation’s estimated capital expenditures for 2014 are as follows: (in millions) Nuclear fuel $900 Production plant 900 Renewable energy projects 300 Uprates 150 Maryland commitments 100 Other 50 Total $2,400 (a)Includes Generation’s share of the investment in nuclear fuel for the co-owned Salem plant. 19(a)(b)(c)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

ComEd ComEd is engaged principally in the purchase and regulated retail sale of electricity and the provision of distribution and transmissionservices to a diverse base of residential, commercial and industrial customers in northern Illinois. ComEd is a public utility under the IllinoisPublic Utilities Act subject to regulation by the ICC related to distribution rates and service, the issuance of securities, and certain otheraspects of ComEd’s business. ComEd is a public utility under the Federal Power Act subject to regulation by FERC related to transmissionrates and certain other aspects of ComEd’s business. Specific operations of ComEd are also subject to the jurisdiction of various otherFederal, state, regional and local agencies. Additionally, ComEd is subject to NERC mandatory reliability standards. ComEd’s retail service territory has an area of approximately 11,400 square miles and an estimated population of 9 million. The serviceterritory includes the City of Chicago, an area of about 225 square miles with an estimated population of 2.7 million. ComEd hasapproximately 3.8 million customers. ComEd’s franchises are sufficient to permit it to engage in the business it now conducts. ComEd’s franchise rights are generallynonexclusive rights documented in agreements and, in some cases, certificates of public convenience issued by the ICC. With fewexceptions, the franchise rights have stated expiration dates ranging from 2014 to 2066. ComEd anticipates working with the appropriateagencies to extend or replace the franchise agreements prior to expiration. ComEd’s kWh deliveries and peak electricity load are generally higher during the summer and winter months, when temperatureextremes create demand for either summer cooling or winter heating. ComEd’s highest peak load occurred on July 20, 2011, and was23,753 MWs; its highest peak load during a winter season occurred on January 6, 2014, and was 16,514 MWs. Retail Electric Services Electric revenues and purchased power expense are affected by fluctuations in customers’ purchases from competitive electricgeneration suppliers. All ComEd customers have the ability to purchase electricity from a competitive electric generation supplier. Thecustomers’ choice activity affects revenue collected from customers related to supplied energy; however, that activity has no impact on electricrevenue net of purchased power expense. ComEd’s cost of electric supply is passed without markup directly through to those customers notserved by a competitive electric generation supplier and those rates are subject to adjustment monthly to recover or refund the differencebetween ComEd’s actual cost of electricity delivered and the amount included in rates. For those customers that choose a competitive electricgeneration supplier, ComEd acts as the billing agent but does not record revenues or expenses related to the electric supply. ComEd remainsthe distribution service provider for all customers in its service territory and charges a regulated rate for distribution service. See ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS for additionalinformation on customer switching to competitive electric generation suppliers, and Note 3 of the Combined Notes to Consolidated FinancialStatements for additional information on ComEd’s electricity procurement process and for additional information. Under Illinois law, ComEd is required to deliver electricity to all customers. ComEd’s obligation to provide generation supply service,which is referred to as a POLR obligation, primarily varies by customer size. ComEd’s obligation to provide such service to residentialcustomers and other small customers with demands of under 100 kWs continues for all customers who do not choose a competitive electricgeneration supplier or who choose to return to ComEd after taking service from a competitive electric generation supplier. ComEd does nothave a fixed-price generation supply service obligation to most of its largest customers with demands of 100 kWs or greater, as this group ofcustomers has previously been declared competitive. Customers with competitive declarations may still purchase power and energy fromComEd, but only at hourly market prices. 20Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Since 2011, ComEd’s distribution rates are established through a performance-based rate formula pursuant to EIMA. EIMA also provides a structure for substantial capital investment by utilities over a ten-year period tomodernize Illinois’ electric utility infrastructure. In addition, as long as ComEd is subject to EIMA, ComEd will fund customer assistanceprograms for low-income customers, which amounts will not be recoverable through rates. ComEd files an annual reconciliation of the revenue requirement in effect in a given year to reflect the actual costs that the ICCdetermines are prudently and reasonably incurred for such year. Under the terms of EIMA, ComEd’s target rate of return on common equityis subject to reduction if ComEd does not deliver the reliability and customer service benefits, as defined, it has committed to over the ten-year life of the investment program. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information. Electric Distribution Rate Cases. The ICC issued an order in ComEd’s 2007 electric distribution rate case (2007 Rate Case)approving a $274 million increase in ComEd’s annual delivery services revenue requirement, which became effective in September 2008.In the order, the ICC authorized a 10.3% rate of return on common equity. On February 23, 2012, the ICC issued an order in the remandproceeding requiring ComEd to provide a refund of approximately $37 million to customers related to the treatment of post-test yearaccumulated depreciation. ComEd and several other parties filed appeals of the rate order with the Illinois Appellate Court (Court). OnSeptember 27, 2013, the Court ruled against ComEd on the accumulated depreciation issue and affirmed that ComEd owes a refund tocustomers of $37 million. As of December 31, 2013, and December 31, 2012, ComEd was fully reserved for this liability. ComEd will notseek rehearing or appeal on this matter and is working with the ICC on the process and timing for a refund to customers. On May 24, 2011, the ICC issued an order in ComEd’s 2010 electric distribution rate case (2010 Rate Case), which became effectiveon June 1, 2011. The order approved a $143 million increase to ComEd’s annual delivery service revenue requirement and a 10.5% rate ofreturn on common equity. The order has been appealed to the Court by several parties. On May 16, 2013, the Court dismissed as moot theappeals of the ICC’s order in the 2010 Rate Case as ComEd now recovers distribution costs under EIMA through a pre-established formularate tariff. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information on ComEd’s electricdistribution rate cases. Procurement-Related Proceedings. Since June 2009, the IPA designs, and the ICC approves, an electricity supply portfolio forComEd and the IPA administers a competitive process under which ComEd procures its electricity supply from various suppliers, includingGeneration. As required by EIMA, in February 2012 the IPA completed procurement events for energy and REC requirements for the June2013 through December 2017 period. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information onComEd’s procurement plans. See Note 22 of the Combined Notes to Consolidated Financial Statements for additional information onComEd’s energy commitments. Continuous Power Interruption. The Illinois Public Utilities Act provides that in the event an electric utility, such as ComEd,experiences a continuous power interruption of four hours or more that affects (in ComEd’s case) more than 30,000 customers, the utilitymay be liable for actual damages suffered by customers as a result of the interruption and may be responsible for reimbursement of localgovernmental emergency and contingency expenses incurred in connection with the interruption. Recovery of consequential damages isbarred. The affected utility may seek from the ICC a waiver of these liabilities when the utility can show that the cause of the interruption wasunpreventable damage due to weather events or conditions, customer tampering, or certain other causes enumerated in the law.

Past financial performance is no guarantee of future results. Smart Meter, Smart Grid and Energy Efficiency Programs Smart Meter and Smart Grid Programs. On January 6, 2012, ComEd filed its Infrastructure Investment Plan with the ICC. Underthat plan, ComEd will invest approximately $2.6 billion over ten years to modernize and storm-harden its distribution system and toimplement smart grid technology. On April 23, 2012, ComEd filed its initial AMI Deployment Plan with the ICC, which was approved by theICC on June 22, 2012, with certain modifications. ComEd outlined the new deployment schedule within testimony provided in the AMI PlanRehearing and filed a revised AMI deployment plan with the ICC. On December 5, 2012, the ICC approved ComEd’s revised AMIdeployment plan. On June 5, 2013, the ICC issued an interim Order approving ComEd’s accelerated AMI deployment plan consistent withthe provisions of Senate Bill 9. The deployment plan provides for the installation of 4 million electric smart meters, of which more than60,000 meters were installed by the end of 2013. Energy Efficiency Programs. As a result of the Illinois Settlement Legislation, electric utilities in Illinois are required to include cost-effective energy efficiency resources in their plans to meet an incremental annual program energy savings requirement of 0.2% of energydelivered to retail customers for the year ended June 1, 2009, which increases annually to 2.0% of energy delivered in the year commencingJune 1, 2015 and each year thereafter. Additionally, during the ten-year period that began June 1, 2008, electric utilities must implement cost-effective demand response measures to reduce peak demand by 0.1% over the prior year for eligible retail customers. The energy efficiencyand demand response goals are subject to rate impact caps each year. Utilities are allowed recovery of costs for energy efficiency and demandresponse programs, subject to approval by the ICC. In December 2010, the ICC approved ComEd’s second three-year Energy Efficiency andDemand Response Plan covering the period June 2011 through May 2014. The plans are designed to meet the Illinois SettlementLegislation’s energy efficiency and demand response goals through May 2014, including reductions in delivered energy to all retailcustomers and in the peak demand of eligible retail customers. EIMA provides for additional energy efficiency in Illinois. Starting in the June 2013—May 2014 period and occurring annually thereafter,as part of the IPA procurement plan, ComEd is to include cost-effective expansion of current energy efficiency programs, any additional newcost-effective program and/or third-party energy efficiency programs that are identified through a request for proposal (“RFP”) process. All cost-effective energy efficiency programs are included in the IPA procurement plan for consideration of implementation. While these programs aremonitored separately from the Energy Efficiency Portfolio Standard (EEPS), funds for both the EEPS portfolio and IPA energy efficiencyprograms are collected under the same rider. Construction Budget ComEd’s business is capital intensive and requires significant investments primarily in energy transmission and distribution facilities,to ensure the adequate capacity, reliability and efficiency of its system. Based on PJM’s RTEP, ComEd has various constructioncommitments, as discussed in Note 3 of the Combined Notes to Consolidated Financial Statements. ComEd’s most recent estimate ofcapital expenditures for electric plant additions and improvements for 2014 is $1,775 million, which includes RTEP projects andinfrastructure modernization resulting from EIMA.

PECO is apublic utility under the Pennsylvania Public Utility Code subject to regulation by the PAPUC as to electric and gas distribution rates andservice, the issuances of certain securities and certain other aspects of PECO’s operations. PECO is a public utility under the Federal PowerAct subject to regulation by FERC as to transmission rates and certain other aspects of PECO’s business and by the U.S. Department ofTransportation as to pipeline safety and other areas of gas operations. Specific operations of PECO are subject to the jurisdiction of variousother Federal, state, regional and local agencies. Additionally, PECO is also subject to NERC mandatory reliability standards. PECO’s combined electric and natural gas retail service territory has an area of approximately 2,100 square miles and an estimatedpopulation of 4.0 million. PECO provides electric distribution service in an area of approximately 1,900 square miles, with a population ofapproximately 3.9 million, including approximately 1.5 million in the City of Philadelphia. PECO provides natural gas distribution service inan area of approximately 1,900 square miles in southeastern Pennsylvania adjacent to the City of Philadelphia, with a population ofapproximately 2.4 million. PECO delivers electricity to approximately 1.6 million customers and natural gas to approximately 501,000customers. PECO has the necessary authorizations to provide regulated electric and natural gas distribution service in the various municipalities orterritories in which it now supplies such services. PECO’s authorizations consist of charter rights and certificates of public convenienceissued by the PAPUC and/or “grandfathered rights,” which are rights generally unlimited as to time and generally exclusive from competitionfrom other electric and natural gas utilities. In a few defined municipalities, PECO’s natural gas service territory authorizations overlap withthat of another natural gas utility; however, PECO does not consider those situations as posing a material competitive or financial threat. PECO’s kWh sales and peak electricity load are generally higher during the summer and winter months, when temperature extremescreate demand for either summer cooling or winter heating. PECO’s highest peak load occurred on July 22, 2011 and was 8,983 MW; itshighest peak load during winter months occurred on January 7, 2014 and was 7,148 MW. PECO’s natural gas sales are generally higher during the winter months when cold temperatures create demand for winter heating.PECO’s highest daily natural gas send out occurred on January 7, 2014 and was 760 mmcf. Retail Electric Services PECO’s retail electric sales and distribution service revenues are derived pursuant to rates regulated by the PAPUC. Pennsylvaniapermits competition by competitive electric generation suppliers for the supply of retail electricity while retail transmission and distributionservice remains regulated under the Competition Act. At December 31, 2013, there were 87 competitive electric generation suppliers servingPECO customers. At December 31, 2013, the number of retail customers purchasing energy from a competitive electric generation supplierwas 531,500 representing approximately 34% of total retail customers. Retail deliveries purchased from competitive electric generationsuppliers represented approximately 68% of PECO’s retail kWh sales for the year ended December 31, 2013. Customers that choose acompetitive electric generation supplier are not subject to rates for PECO’s electric supply procurement costs and retail transmission servicecharges. PECO presents on customer bills its electric supply Price to Compare, which is updated quarterly, to assist customers with theevaluation of offers from competitive electric generation suppliers. Customer choice program activity affects revenue collected from customers related to supplied energy; however, that activity has noimpact on electric revenue net of purchased power expense or PECO’s financial position.

For those customers that choose a competitive electricgeneration supplier, PECO acts as the billing agent but does not record revenues or purchase power expense related to this electric supply.PECO remains the distribution service provider for all customers in its service territory and charges a regulated rate for distribution service. Procurement Proceedings. PECO’s electric supply for its customers is procured through contracts executed in accordance with itsPAPUC-approved DSP Programs. PECO entered into contracts with PAPUC-approved bidders, including Generation, as part of its DSP Icompetitive procurements conducted since June 2009 for its default electric supply beginning January 2011, which included fixed price fullrequirement contracts for all procurement classes, spot market price full requirements contracts for the commercial and industrialprocurement classes, and block energy contracts for the residential procurement class. In September 2012, PECO completed its lastcompetitive procurement for electric supply under its first DSP Program, which expired on May 31, 2013. On October 12, 2012, the PAPUC approved PECO’s second DSP Program, which was filed with the PAPUC in January 2012. Theplan outlines how PECO is purchasing electric supply for default service customers from June 1, 2013 through May 31, 2015. Pursuant tothe second DSP Program, PECO is procuring electric supply through five competitive procurements for fixed price full requirementscontracts of two years or less for the residential and small and medium commercial classes and spot market price full requirement contractsfor the large commercial and industrial class load. In December 2012 and February 2013, PECO entered into contracts with PAPUC-approved bidders, including Generation, for its residential and small and medium commercial classes that began in June 2013. InSeptember 2013, PECO entered into contracts with PAPUC-approved bidders, including Generation, for its residential and small andmedium commercial classes that began in December 2013. In January 2014, PECO entered into contracts with PAPUC-approved bidders,including Generation, for its residential and small, medium and large commercial classes that will begin in June 2014. Charges incurred forelectric supply procured through contracts with Generation are included in purchased power from affiliates on PECO’s Statement ofOperations and Comprehensive Income. The second DSP Program also includes a number of retail market enhancements recommended by the PAPUC in its previouslyissued Retail Markets Intermediate Work Plan Order. PECO was also directed to allow its low-income Customer Assistance Program (CAP)customers to purchase their generation supply from competitive electric generation suppliers beginning April 1, 2014. On May 1, 2013,PECO filed a Petition for Approval of its CAP Shopping Plan with the PAPUC, which the PAPUC granted and denied in part on January 9,2014. PECO and other parties to the proceeding filed petitions for reconsideration of the Commission’s decision on February 10, 2014, andthese petitions are currently pending before the PAPUC. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information. Smart Meter, Smart Grid and Energy Efficiency Programs Smart Meter and Smart Grid Programs. In April 2010, the PAPUC approved PECO’s Smart Meter Procurement and Installation Plan,which was filed in accordance with the requirements of Act 129. Also, in April 2010, PECO entered into a Financial Assistance Agreementwith the DOE for SGIG funds under the ARRA of 2009. Under the SGIG, PECO has been awarded $200 million, the maximum grantallowable under the program, for its SGIG project—Smart Future Greater Philadelphia. The SGIG funds are being used to offset the totalimpact to ratepayers of the smart meter deployment required by Act 129. On January 18, 2013, PECO filed with the PAPUC its universaldeployment plan for approval of its proposal to deploy the remainder of the 1.6 million smart meters on an accelerated basis by the 24Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

On May 31, 2013, PECO and interested parties filed a Joint Petition for Settlement of the universal deployment plan with thePAPUC, which was approved without modification on August 15, 2013. In total, PECO currently expects to spend up to $595 million and$120 million on its smart meter and smart grid infrastructure, respectively, before considering the $200 million SGIG. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information. Energy Efficiency Programs. PECO’s PAPUC-approved Phase I EE&C plan had a four-year term that began on June 1, 2009 andconcluded on May 31, 2013. The Phase I Plan sets forth how PECO would meet the required reduction targets established by Act 129’sEE&C provisions, which included a 3% reduction in electric consumption in PECO’s service territory and a 4.5% reduction in PECO’sannual system peak demand in the 100 hours of highest demand by May 31, 2013. The peak demand period ended on September 30, 2012and PECO communicated its compliance with the reduction targets in a preliminary report with the PAPUC on March 1, 2013. The finalcompliance report was filed with the PAPUC on November 15, 2013. The PAPUC issued its Phase II EE&C implementation order on August 2, 2012, that provides energy consumption reductionrequirements for the second phase of Act 129’s EE&C programs, which went into effect on June 1, 2013. The PAPUC deferred a decision onpeak demand reduction requirements until late 2013. On February 28, 2013, the PAPUC approved PECO’s three-year EE&C Phase II planthat was filed with the PAPUC on November 1, 2012, and sets forth how PECO will reduce electric consumption by at least 1,125,852 MWhin its service territory for the period June 1, 2013 through May 31, 2016. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information. Natural Gas PECO’s natural gas sales and distribution service revenues are derived through natural gas deliveries at rates regulated by thePAPUC. PECO’s purchased natural gas cost rates, which represent a significant portion of total rates, are subject to quarterly adjustmentsdesigned to recover or refund the difference between the actual cost of purchased natural gas and the amount included in rates withoutmarkup through the PGC. PECO’s natural gas customers have the right to choose their natural gas suppliers or to purchase their gas supply from PECO at cost.At December 31, 2013, the number of retail customers purchasing natural gas from a competitive natural gas supplier was 66,400,representing approximately 13% of total retail customers. Retail deliveries purchased from competitive natural gas suppliers representedapproximately 19% of PECO’s mmcf sales for the year ended December 31, 2013. PECO provides distribution, billing, metering,installation, maintenance and emergency response services at regulated rates to all its customers in its service territory. Procurement Proceedings. PECO’s natural gas supply is purchased from a number of suppliers primarily under long-term firmtransportation contracts for terms of up to three years in accordance with its annual PAPUC PGC settlement. PECO’s aggregate annual firmsupply under these firm transportation contracts is 34 million dekatherms. Peak natural gas is provided by PECO’s liquefied natural gas(LNG) facility and propane-air plant. PECO also has under contract 21 million dekatherms of underground storage through serviceagreements. Natural gas from underground storage represents approximately 30% of PECO’s 2013-2014 heating season planned supplies.

Construction Budget PECO’s business is capital intensive and requires significant investments primarily in electric transmission and electric and naturalgas distribution facilities to ensure the adequate capacity, reliability and efficiency of its system. PECO, as a transmission facilities owner,has various construction commitments under PJM’s RTEP as discussed in Note 3 of the Combined Notes to Consolidated FinancialStatements. PECO’s most recent estimate of capital expenditures for plant additions and improvements for 2014 is $625 million, whichincludes RTEP projects and capital expenditures related to the smart meter and smart grid project net of expected SGIG DOEreimbursements. BGE BGE is engaged principally in the purchase and regulated retail sale of electricity and the provision of transmission and distributionservices to retail customers in central Maryland, including the City of Baltimore, as well as the purchase and regulated retail sale of naturalgas and the provision of distribution services to retail customers in central Maryland, including the City of Baltimore. BGE is a public utilityunder the Public Utilities Article of the Maryland Annotated Code subject to regulation by the MDPSC as to electric and gas distribution ratesand service, the issuances of certain securities and certain other aspects of BGE’s operations. BGE is a public utility under the FederalPower Act subject to regulation by FERC as to transmission rates and certain other aspects of BGE’s business and by the U.S. Departmentof Transportation as to pipeline safety and other areas of gas operations. Specific operations of BGE are subject to the jurisdiction of variousother Federal, state, regional and local agencies. Additionally, BGE is also subject to NERC mandatory reliability standards. BGE serves an estimated population of 2.8 million in its 2,300 square mile combined electric and gas retail service territory. BGEprovides electric distribution service in an area of approximately 2,300 square miles and gas distribution service in an area of approximately800 square miles, both with a population of approximately 2.8 million, including approximately 621,000 in the City of Baltimore. BGEdelivers electricity to approximately 1.2 million customers and natural gas to approximately 655,000 customers. BGE has the necessary authorizations to provide regulated electric and natural gas distribution services in the various municipalitiesand territories in which it now supplies such services. With respect to electric distribution service, BGE’s authorizations consist of charterrights, a state-wide franchise grant and a franchise grant from the City of Baltimore. The franchise rights are not exclusive and are perpetual.With respect to natural gas distribution service, BGE’s authorizations consist of charter rights, a perpetual state-wide franchise grant, andfranchises granted by all the municipalities and/or governmental bodies in which BGE now supplies services. The franchise grants are notexclusive; some are perpetual and some are for a limited duration, which BGE anticipates being able to extend or replace prior to expiration. BGE’s kWh sales and peak electricity load are generally higher during the summer and winter months, when temperature extremescreate demand for either summer cooling or winter heating. BGE’s highest peak load occurred on July 21, 2011 and was 7,236 MW; itshighest peak load during winter months occurred on January 7, 2014 and was 6,526 MW. BGE’s natural gas sales are generally higher during the winter months when cold temperatures create demand for winter heating.BGE’s highest daily natural gas send out occurred on February 5, 2007 and was 840 mmcf. The demand for electricity and gas is affected by weather and usage conditions. The MDPSC has allowed BGE to record a monthlyadjustment to its electric and gas distribution revenues from all residential customers, commercial electric customers, the majority of largeindustrial electric customers, and all firm service gas customers to eliminate the effect of abnormal weather and usage patterns per 26Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. customer on BGE’s electric and gas distribution volumes, thereby recovering a specified dollar amount of distribution revenues percustomer, by customer class, regardless of changes in consumption levels. This adjustment allows BGE to recognize revenues at MDPSC-approved levels per customer, regardless of what actual distribution volumes were for a billing period (referred to as “revenue decoupling”).Therefore, while these revenues are affected by customer growth, they will not be affected by actual weather or usage conditions. BGE billsor credits affected customers in subsequent months for the difference between approved revenue levels under revenue decoupling and actualcustomer billings. Retail Electric Services BGE’s retail electric sales and distribution service revenues are derived from electricity deliveries at rates regulated by the MDPSC. Asa result of the deregulation of electric generation in Maryland effective July 1, 2000, all customers can choose a competitive electric generationsupplier. While BGE does not sell electric supply to all customers in its service territory, BGE continues to deliver electricity to all customersand provides meter reading, billing, emergency response, and regular maintenance services. Customer choice program activity affectsrevenue collected from customers related to supplied energy; however, that activity has minimal impact on electric revenue net of purchasedpower expense or BGE’s financial position. At December 31, 2013, there were 73 competitive electric generation suppliers serving BGEcustomers. At December 31, 2013, the number of retail customers purchasing energy from a competitive electric generation supplier wasapproximately 399,000, representing 32% of total retail customers. Retail deliveries purchased from competitive electric generation suppliersrepresented approximately 61% of BGE’s retail kWh sales for the year ended December 31, 2013. BGE is obligated to provide market-based SOS to all of its electric customers. The SOS rates charged recover BGE’s wholesale powersupply costs and include an administrative fee. The administrative fee includes a commercial and industrial shareholder return componentand an incremental cost component. Bidding to supply BGE’s market-based SOS occurs through a competitive bidding process approved bythe MDPSC. Successful bidders, which may include Generation, will execute contracts with BGE for terms of three months or two years. BGE is obligated by the MDPSC to provide several variations of SOS to commercial and industrial customers depending on customerload. Electric Distribution Rate Cases. In December 2010, the MDPSC issued an abbreviated electric rate order authorizing BGE toincrease electric distribution rates for service rendered on or after December 4, 2010 by no more than $31 million. In March 2011, theMDPSC issued a comprehensive rate order setting forth the details of the decision contained in its abbreviated combined electric and gasdistribution rate order issued in December 2010. As part of the March 2011 comprehensive rate order, BGE was authorized to defer $19million of costs as regulatory assets. These costs are being recovered over a 5-year period beginning in December 2010 and include thedeferral of $16 million of storm costs incurred in February 2010. The regulatory asset for the storm costs earns the authorized rate of return. On July 27, 2012, BGE filed an application for an increase to its electric base rates with the MDPSC. On February 22, 2013, theMDPSC issued an order in BGE’s 2012 electric rate case for increases in annual distribution service revenue of $81 million. The electricdistribution rate increase was set using an allowed return on equity of 9.75%. On May 17, 2013, BGE filed an application for an increase to its electric base rates with the MDPSC. On December 13, 2013, theMDPSC issued an order in BGE’s 2013 electric distribution rate case authorizing an increase in annual distribution service revenue of $34million. The electric distribution rate increase was set using an allowed return on equity of 9.75%. The approved electric distribution ratebecame effective for services rendered on or after December 13, 2013. 27Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Smart Meter and Energy Efficiency Programs Smart Meter Programs. In August 2010, the MDPSC approved BGE’s $480 million SGIP, which includes deployment of a two-waycommunications network, 2 million smart electric and gas meters and modules, new customer pricing programs, a new customer webportal and numerous enhancements to BGE operations. Also, in April 2010, BGE entered into a Financial Assistance Agreement with theDOE for SGIG funds under the ARRA of 2009. Under the SGIG, BGE has been awarded $200 million, the maximum grant allowableunder the program, to support its Smart Grid, Peak Rewards and CC&B initiatives. The SGIG funding is being used to reduce significantlythe rate impact of those investments on BGE customers. As of December 31, 2013, BGE has billed the entire $200 million grant to theDOE. Energy Efficiency Programs. BGE’s energy efficiency programs include a CFL program, retrofit programs, an energy efficientappliance rebate and trade-in program, rebates and energy efficiency programs for non-profit, educational, governmental and businesscustomers, customer incentives for energy management programs and incentives to help customers reduce energy demand during peakperiods. The MDPSC initially approved a full portfolio of conservation programs as well as a customer surcharge to recover the associatedcosts. This customer surcharge is updated annually. In December 2011, the MDPSC approved BGE’s conservation programs forimplementation in 2012 through 2014. Natural Gas BGE’s natural gas sales are derived pursuant to a MBR mechanism that applies to customers who buy their gas from BGE. Under thismechanism, BGE’s actual cost of gas is compared to a market index (a measure of the market price of gas in a given period). The differencebetween BGE’s actual cost and the market index is shared equally between shareholders and customers. Customer choice program activityaffects revenue collected from customers related to supplied natural gas; however, that activity has minimum impact on gas revenue net ofpurchased power expense or BGE’s financial position. At December 31, 2013, there were 41 competitive natural gas suppliers serving BGEcustomers. At December 31, 2013, the number of retail customers purchasing fuel from a competitive natural gas supplier wasapproximately 172,000 representing 26% of total retail customers. Retail deliveries purchased from competitive natural gas suppliersrepresented approximately 54% of BGE’s retail mmcf sales for the year ended December 31, 2013. BGE must secure fixed price contracts for at least 10%, but not more than 20%, of forecasted system supply requirements for flowing(i.e., non-storage) gas for the November through March period. These fixed price contracts are recovered under the MBR mechanism and arenot subject to sharing. BGE meets its natural gas load requirements through firm pipeline transportation and storage entitlements. BGE’scurrent pipeline firm transportation entitlements to serve its firm loads are 362 mmcf per day. BGE’s current maximum storage entitlements are 284 mmcf per day. To supplement its gas supply at times of heavy winter demandsand to be available in temporary emergencies affecting gas supply, BGE has: • a liquefied natural gas facility for the liquefaction and storage of natural gas with a total storage capacity of 1,055 mmcf and a dailycapacity of 332 mmcf, • a liquefied natural gas facility for natural gas system pressure support with a total storage capacity of 6 mmcf and a daily capacity of6 mmcf, and • a propane air facility and a mined cavern with a total storage capacity equivalent to 546 mmcf and a daily capacity of 85 mmcf. BGE has under contract sufficient volumes of propane for the operation of the propane air facility and is capable of liquefying sufficientvolumes of natural gas during the summer months for operations 28Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. of its liquefied natural gas facility during peak winter periods. BGE historically has been able to arrange short-term contracts or exchangeagreements with other gas companies in the event of short-term disruptions to gas supplies or to meet additional demand. BGE also participates 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 sharedbetween shareholders and customers. BGE makes these sales as part of a program to balance its supply of, and cost of, natural gas. Natural Gas Distribution Rate Cases. In December 2010, the MDPSC issued a rate order authorizing BGE to increase the gasdistribution base revenue requirement for service rendered on or after December 4, 2010 by no more than $9.8 million. In March 2011, theMDPSC issued a comprehensive rate order setting forth the details of the decision contained in its abbreviated combined electric and gasdistribution rate order issued in December 2010. On July 27, 2012, BGE filed an application for an increase to its gas base rates with the MDPSC. On February 22, 2013, the MDPSCissued an order in BGE’s 2012 gas rate case for increases in annual distribution service revenue of $32 million. The electric distribution rateincrease was set using an allowed return on equity of 9.60%. On May 17, 2013, BGE filed an application for an increase to its gas base rates with the MDPSC. On December 13, 2013, theMDPSC issued an order in BGE’s 2013 natural gas distribution rate case authorizing an increase in annual distribution service revenue of$12 million. The gas distribution rate increase was set using an allowed return on equity of 9.60%. The approved natural gas distribution ratebecame effective for services rendered on or after December 13, 2013. Construction Budget BGE’s business is capital intensive and requires significant investments primarily in electric and natural gas distribution and electrictransmission facilities to ensure the adequate capacity, reliability and efficiency of its system. BGE, as a transmission facilities owner, hasvarious construction commitments under PJM’s RTEP as discussed in Note 3 of the Combined Notes to Consolidated FinancialStatements. BGE’s most recent estimate of capital expenditures for plant additions and improvements for 2014 is approximately $600million, which includes capital expenditures related to the SGIP net of expected SGIG DOE reimbursements. ComEd, PECO and BGE Transmission Services ComEd, PECO and BGE provide unbundled transmission service under rates approved by FERC. FERC has used its regulation oftransmission to encourage competition for wholesale generation services and the development of regional structures to facilitate regionalwholesale markets. Under FERC’s open access transmission policy promulgated in Order No. 888, ComEd, PECO and BGE, as ownersof transmission facilities, are required to provide open access to their transmission facilities under filed tariffs at cost-based rates. ComEd,PECO and BGE are required to comply with FERC’s Standards of Conduct regulation governing the communication of non-publicinformation between the transmission owner’s employees and wholesale merchant employees. PJM is the ISO and the FERC-approved RTO for the Mid-Atlantic and Midwest regions. PJM is the transmission provider under, andthe administrator of, the PJM Open Access Transmission Tariff (PJM Tariff), operates the PJM energy, capacity and other markets, and,through central dispatch, controls 29Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

ComEd, PECO and BGE are members of PJM and provide regionaltransmission service pursuant to the PJM Tariff. ComEd, PECO, BGE and the other transmission owners in PJM have turned over controlof their transmission facilities to PJM, and their transmission systems are currently 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 members at rates based onthe costs of transmission service. ComEd’s transmission rates are established based on a formula that was approved by FERC in January 2008. FERC’s orderestablishes the agreed-upon treatment of costs and revenues in the determination of network service transmission rates and the process forupdating the formula rate calculation on an annual basis. PECO default service customers are charged for retail transmission services through a rider designed to recover PECO’s PJMtransmission network service charges and RTEP charges on a full and current basis in accordance with the 2010 electric distribution ratecase settlement. The transmission rate in the PJM Open Access Transmission Tariff under which PECO incurs costs to serve its default servicecustomers and earns revenue as a transmission facility owner is a FERC-approved rate. This is the rate that all load serving entities in thePECO transmission zone pay for wholesale transmission service. BGE’s transmission rates are established based on a formula that was approved by FERC in April 2006. FERC’s order establishes theagreed-upon treatment of costs and revenues in the determination of network service transmission rates and the process for updating theformula rate calculation on an annual basis. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information regarding transmission services.

Environmental Regulation General Exelon, Generation, ComEd, PECO and BGE are subject to comprehensive and complex legislation regarding environmental mattersby the federal government and various state and local jurisdictions in which they operate their facilities. The Registrants are also subject toregulations administered by the U.S. EPA and various state and local environmental protection agencies. Federal, state and local regulationincludes 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 managementteam to address environmental compliance and strategy, including the CEO; the Senior Vice President, Corporate Strategy and ChiefSustainability Officer; the Corporate Environmental Strategy Director and the Environmental Regulatory Strategy Director, as well as seniormanagement of Generation, ComEd, PECO and BGE. Performance of those individuals directly involved in environmental compliance andstrategy is reviewed and affects compensation as part of the annual individual performance review process. The Exelon board has delegatedto its corporate governance committee authority to oversee Exelon’s compliance with laws and regulations and its strategies and efforts toprotect and improve the quality of the environment, including, Exelon’s climate change and sustainability policies and programs, and Exelon2020, Exelon’s comprehensive business and environmental plan, as discussed in further detail below. The Exelon board has also delegatedto its generation oversight committee authority to oversee environmental, health and safety issues relating to Generation. The respectiveboards of ComEd, PECO and BGE, which each include directors who also serve on the Exelon board, oversee environmental, health andsafety issues related to ComEd, PECO and BGE. Air Quality Air quality regulations promulgated by the U.S. EPA and the various state and local environmental agencies in Illinois, Maryland,Massachusetts, New York, Pennsylvania and Texas in accordance with the Federal Clean Air Act impose restrictions on emission ofparticulates, sulfur dioxide (SO), nitrogen oxides (NO), mercury and other pollutants and require permits for operation of emissionssources. Such permits have been obtained by Exelon’s subsidiaries and must be renewed periodically. The Clean Air Act establishes acomprehensive and complex national program to reduce substantially air pollution from power plants. Advanced emission controls for SOand NOx have been installed at all of Generation’s co-owned bituminous coal-fired units. See Note 22 of the Combined Notes to Consolidated Financial Statements for additional information regarding clean air regulation andlegislation in the forms of the CSAPR and CAIR, the regulation of hazardous air pollutants from coal- and oil-fired electric generating facilitiesunder MATS, and regulation of GHG emissions, in addition to NOVs issued to Generation and ComEd for alleged violations of the CleanAir Act. Water Quality Under the Clean Water Act, NPDES permits for discharges into waterways are required to be obtained from the U.S. EPA or from thestate environmental agency to which the permit program has been delegated and must be renewed periodically.

See Note 22 of the Combined Notes to Consolidated Financial Statements for additional information regarding the impact to Exelon ofstate permitting agencies’ administration of the Phase II rule implementing Section 316(b) of the Clean Water Act. Generation is also subject to the jurisdiction of certain other state and regional agencies and compacts, including the Delaware RiverBasin Commission and the Susquehanna River Basin Commission. Solid and Hazardous Waste The CERCLA provides for immediate response and removal actions coordinated by the U.S. EPA in the event of threatened releases ofhazardous substances into the environment and authorizes the U.S. EPA either to clean up sites at which hazardous substances havecreated actual or potential environmental hazards or to order persons responsible for the situation to do so. Under CERCLA, generators andtransporters of hazardous substances, as well as past and present owners and operators of hazardous waste sites, are strictly, jointly andseverally liable for the cleanup costs of waste at sites, most of which are listed by the U.S. EPA on the National Priorities List (NPL). ThesePRPs can be ordered to perform a cleanup, can be sued for costs associated with a U.S. EPA-directed cleanup, may voluntarily settle with theU.S. EPA concerning their liability for cleanup costs, or may voluntarily begin a site investigation and site remediation under state oversightprior to listing on the NPL. Various states, including Illinois, Maryland and Pennsylvania, have also enacted statutes that contain provisionssubstantially similar to CERCLA. In addition, RCRA governs treatment, storage and disposal of solid and hazardous wastes and cleanup ofsites where such activities were conducted. Generation, ComEd, PECO and BGE and their subsidiaries are, or are likely to become, parties to proceedings initiated by the U.S.EPA, state agencies and/or other responsible parties under CERCLA and RCRA with respect to a number of sites, including MGP sites, ormay undertake to investigate and remediate sites for which they may be subject to enforcement actions by an agency or third-party. See Note 22 of the Combined Notes to Consolidated Financial Statements for additional information regarding solid and hazardouswaste regulation and legislation. Environmental Remediation ComEd’s, PECO’s and BGE’s environmental liabilities primarily arise from contamination at former MGP sites. ComEd, pursuant toan ICC order, and PECO, pursuant to settlements of natural gas distribution rate cases with the PAPUC, have an on-going process torecover environmental remediation costs of the MGP sites through a provision within customer rates. While BGE does not have a rider forMGP clean-up costs, BGE has historically received recovery of actual clean-up costs on a site-specific basis in distribution rates. The amountto be expended in 2014 at Exelon for compliance with environmental remediation related to contamination at former MGP sites is expected tototal $40 million, consisting of $33 million, $6 million and $1 million at ComEd, PECO and BGE, respectively. Generation’s environmental liabilities primarily arise from contamination at current and former generation and waste storage facilities.As of December 31, 2013, Generation has established an appropriate liability to comply with environmental remediation requirementsincluding contamination attributable to low level radioactive residues at a storage and reprocessing facility named Latty Avenue, and at adisposal facility named West Lake Landfill, both near St. Louis, Missouri related to operations conducted by Cotter Corporation, a formerComEd subsidiary. 32Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Global Climate Change Exelon believes the evidence of global climate change is compelling and that the energy industry, though not alone, is a significantcontributor to the human-caused emissions of GHGs that many in the scientific community believe contribute to global climate change, andas reported by the Intergovernmental Panel on Climate Change in their Fifth Assessment Report Summary for Policy Makers issuesSeptember 2013. Exelon, as a producer of electricity from predominantly low-carbon generating facilities (such as nuclear, hydroelectric, windand solar photovoltaic), has a relatively small GHG emission profile, or carbon footprint, compared to other domestic generators of electricity.By virtue of its significant investment in low-carbon intensity assets, Generation’s emission intensity, or rate of carbon dioxide equivalent(COe) emitted per unit of electricity generated, is among the lowest in the industry. Exelon does produce GHG emissions, primarily at itsfossil fuel-fired generating plants; CO, methane and nitrous oxide are all emitted in this process, with CO representing the largest portionof these GHG emissions. GHG emissions from combustion of fossil fuels represent the majority of Exelon’s direct GHG emissions in2013, although only a small portion of Exelon’s electric supply is from fossil generating plants. Other GHG emission sources at Exeloninclude natural gas (methane) leakage on the natural gas systems, sulfur hexafluoride (SF) leakage in its electric transmission anddistribution operations and refrigerant leakage from its chilling and cooling equipment as well as fossil fuel combustion in its motor vehiclesand usage of electricity at its facilities. Despite its focus on low-carbon generation, Exelon believes its operations could be significantly affectedby the possible physical risks of climate change and by mandatory programs to reduce GHG emissions. See ITEM 1A. RISK FACTORS forinformation regarding the market and financial, regulatory and legislative, and operational risks associated with climate change. Climate Change Regulation. Exelon is, or may become, subject to climate change regulation or legislation at the Federal, regionaland state levels. International Climate Change Regulation. At the international level, the United States has not yet ratified the United Nations KyotoProtocol, which was extended at the 2012 meeting of the United Nations Framework on Climate Change Conference of the Parties (COP18). The Kyoto Protocol now requires participating developed countries to cap GHG emissions at certain levels until 2020, when the newglobal agreement on emissions reduction is scheduled to become effective. This new global agreement for GHG emissions reductions wasagreed to only in concept during the COP18, with a timeline for establishing the global targets by 2015. On November 22, 2013, at the 2013COP 19 held in Warsaw, Poland, participating countries further agreed to provide their “intended nationally determined contributions” by thefirst quarter of 2015 in preparation for formally setting global target in 2015. The other major issues discussed at COP 19 were demands fromdeveloping countries for increased climate finance, and for a new mechanism to help especially vulnerable nations cope with unavoidable“loss and damage” resulting from climate change. Developed countries, which had previously promised to mobilize a total of $100 billion ayear by 2020, refused to set a quantified interim goal for ramping up climate finance. Federal Climate Change Legislation and Regulation. Various stakeholders, including Exelon, legislators and regulators,shareholders and non-governmental organizations, as well as other companies in many business sectors are considering ways to addressthe climate change issue, 332226Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

It is highly uncertain whether Federal legislation to reduce GHG emissions willbe enacted. If such legislation is adopted, Exelon may incur costs either to further limit or offset the GHG emissions from its operations or toprocure emission allowances or credits. In June 2013, the White House released the President’s Climate Action Plan which consists of awide variety of executive actions targeting GHG reductions, preparing for the impacts of climate change and showing leadershipinternationally; but the plan did not directly trigger any new requirements or legislative action. The U.S. EPA is addressing the issue of carbon dioxide (CO2) emissions regulation for new and existing electric generating unitsthrough the New Source Performance Standards (NSPS) under Section 111 of the Clean Air Act. Pursuant to President Obama’s June 25,2013 memorandum to U.S. EPA, the Agency re-proposed a Section 111(b) regulation for new units in September 2013 that may result inmaterial costs of compliance for CO2 emissions for new fossil-fuel electric generating units, particularly coal-fired units. Under thePresident’s memorandum, the U.S. EPA is also required to propose a Section 111(d) rule no later than June 1, 2014 to establish CO2emission regulations for existing stationary sources. Regional and State Climate Change Legislation and Regulation. After a two-year program review, the nine northeast and mid-Atlantic states currently participating in the Regional Greenhouse Gas Reduction Initiative (RGGI) released an updated RGGI Model Ruleand Program Review Recommendations Summary on February 7, 2013. Under the updated RGGI program, which must be approvedpursuant to the applicable legislative and/or regulatory process in each RGGI state, the regional RGGI CO2 budget would be reduced,starting in 2014, from its current 165 million ton level to 91 million tons, with a 2.5 percent reduction in the cap level each year between2015-2020. Included in the new program are provisions for cost containment reserve (CCR) allowances, which will become available if thetotal demand for allowances, above the CCR trigger price, exceeds the number of CO2 allowances available for purchase at auction. (CCRtrigger prices are $4 in 2014, $6 in 2015, $8 in 2016 and $10 in 2017, rising 2.5 percent thereafter to account for inflation). Such an outcomecould put modest upward pressure on wholesale power prices; however, the specifics are currently uncertain. At the state level, the Illinois Climate Change Advisory Group, created by Executive Order 2006-11 on October 5, 2006, made its finalrecommendations on September 6, 2007 to meet the Governor’s GHG reduction goals. At this time, the only requirements imposed by thestate of Illinois are the energy efficiency and renewable portfolio standards in the Illinois Power Act that apply to ComEd. On December 18, 2009, Pennsylvania issued the state’s final Climate Change Action Plan. The plan sets as a target a 30 percentreduction in GHG emissions by 2020. The Climate Change Advisory Committee continues to meet quarterly to review Climate Action WorkPlans for the residential, commercial and industrial sectors. The Climate Change Action Plan does not impose any requirements onGeneration or PECO at this time. The Maryland Commission on Climate Change released its climate action plan on August 27, 2008, recommending that the statebegin implementing 42 greenhouse gas reduction strategies. One of the Plan’s policy recommendations, to adopt science-based regulatorygoals to reduce Maryland’s GHG emissions, was realized with the passage of the Greenhouse Gas Emissions Reduction Act of 2009(GGRA). The law requires Maryland to reduce its GHG emissions by 25 percent below 2006 levels by 2020. It directed the MDE to workwith other state agencies to prepare an implementation plan to meet this goal. The implementation plan was published in October of 2013.Maryland targeted electricity consumption reduction goals required under the “Empower Maryland” program, and mandatory Stateparticipation in the recently updated and enhanced RGGI Program are listed as that sector’s contribution in the plan. The plan also advocatesraising the renewable portfolio standard requirement from 22% by 2022 to 25% by 2022. 34Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Exelon’s Voluntary Climate Change Efforts. In a world increasingly concerned about global climate change and regulatory action toreduce GHG, Exelon’s low-carbon generating fleet is seen by management as a competitive advantage. Exelon remains one of the largest,lowest carbon electric generators in the United States: nuclear for base load, natural gas for marginal and peak demand, hydro and pumpedstorage, and supplemental wind and solar renewables. As further legislation and regulation imposing requirements on emissions of GHGand air pollutants are promulgated, Exelon’s low-carbon, low-emission generation fleet will position the company to benefit from itscomparative advantage over other generation fleets. With the announcement in 2008 of Exelon 2020, Exelon set a voluntary goal to reduce, offset or displace more than 15.7 million metrictonnes of GHG emissions per year by 2020. Exelon updated that goal in 2012 following the Constellation merger to account for theintegration of former Constellation GHG goals. The updated Exelon 2020 goal is to reduce, offset or displace more than 17.5 million metrictonnes of GHG emissions by 2020. The Exelon 2020 goal encompasses three broad areas of focus: reducing or offsetting Exelon’s owncarbon footprint (with the year the asset/operations were acquired by Exelon as the baseline), helping customers and communities reducetheir GHG emissions, and offering more low-carbon electricity in the marketplace. Exelon has been maintaining strong performance towardsachieving the goal and anticipates reaching the 17.5 million tons of annual abatement well before 2020. Renewable and Alternative Energy Portfolio Standards Thirty-nine states and the District of Columbia have adopted some form of RPS requirement. As previously described, Illinois,Pennsylvania and Maryland have laws specifically addressing energy efficiency and renewable energy initiatives. In addition to state levelactivity, RPS legislation has been considered and may be considered again in the future by the United States Congress. Also, states thatcurrently do not have RPS requirements may adopt such legislation in the future. The Illinois Settlement Legislation required that procurement plans implemented by electric utilities include cost-effective renewableenergy resources or approved equivalents such as RECs in amounts that equal or exceed 2% of the total electricity that each electric utilitysupplies to its eligible retail customers by June 1, 2008, increasing to 10% by June 1, 2015, with a goal of 25% by June 1, 2025. Utilities areallowed to pass-through any costs from the procurement of these renewable resources or approved equivalents subject to legislated rateimpact criteria. As of December 31, 2013, ComEd had purchased sufficient renewable energy resources or equivalents, such as RECs, tocomply with the Illinois Settlement Legislation. See Note 3 and Note 22 of the Combined Notes to Consolidated Financial Statements foradditional information. The AEPS Act became effective for PECO on January 1, 2011, following the expiration of PECO’s transition period. During 2013,PECO was required to supply approximately 4.0% of electric energy generated from Tier I (including solar, wind power, low-impacthydropower, geothermal energy, biologically derived methane gas, fuel cells, biomass energy, coal mine methane and black liquor generatedwithin Pennsylvania) through May 31, 2013 and subsequently 4.5% beginning June 1, 2013 and continuing through May 31, 2014. PECOwas also required to supply 6.2% of electric energy generated from Tier II (including waste coal, demand-side management, large-scalehydropower, municipal solid waste, generation of electricity utilizing wood and by-products of the pulping process and wood, distributedgeneration systems and integrated combined coal gasification technology) alternative energy resources, respectively, as measured in AECs.The compliance requirements will incrementally escalate to 8.0% for Tier I and 10.0% for Tier II by 2021. In order to comply with theserequirements, PECO entered into agreements with varying terms with accepted bidders, including Generation, to purchase non-solar Tier I,solar Tier 1 and Tier II AECs. PECO also purchases AECs through its DSP Program full requirement contracts. 35Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Section 7-703 of the Public Utilities Article in Maryland sets forth the RPS requirement, which applies to all retail electricity sales inMaryland by electricity suppliers. The RPS requirement requires that suppliers obtain a specified percentage of the electricity it sells from Tier1 sources (solar, wind, biomass, methane, geothermal, ocean, fuel cell, small hydroelectric, and poultry litter) and Tier 2 sources(hydroelectric, other than pump storage generation, and waste-to-energy). The RPS requirement began in 2006, requiring that suppliersprocure 1.0% and 2.5% from Tier 1 and Tier 2 sources, respectively, escalating in 2022 to 22.0% from Tier 1 sources, including at least 2.0%from solar energy, and a phase out of Tier 2 resource options by 2022. In 2013, 8.2% was required from Tier 1 renewable sources, includingat least 0.25% derived from solar energy, and 2.5% from Tier 2 renewable sources. The wholesale suppliers that supply power to the state’sutilities through the SOS procurement auctions have the obligation, by contract with those utilities, to comply with and provide itsproportional share of the RPS requirements. Similar to ComEd, PECO and BGE, Generation’s retail electric business must source a portion of the electric load it serves in many ofthe states in which it does business from renewable resources or approved equivalents such as RECs. Potential regulation and legislationregarding renewable and alternative energy resources could increase the pace of development of wind and other renewable/alternative energyresources, which could put downward pressure on wholesale market prices for electricity in some markets where Exelon operates generationassets. At the same time, such developments may present some opportunities for sales of Generation’s renewable power, including fromwind, solar, hydroelectric and landfill gas.

ITEM 1A.RISK FACTORS Each of the Registrants operates in a market and regulatory environment that poses significant risks, many of which are beyond theRegistrant’s control. Management of each Registrant regularly meets with the Chief Risk Officer and the RMC, which comprises officers ofthe Registrants, to identify and evaluate the most significant risks of the Registrants’ businesses, and the appropriate steps to manage andmitigate those risks. The Chief Risk Officer and senior executives of the Registrants discuss those risks with the finance and risk committeeand audit committees of the Exelon board of directors and the ComEd, PECO and BGE boards of directors. In addition, the generationoversight committee of the Exelon board of directors’ evaluates risks related to the generation business. The risk factors discussed belowmay adversely affect one or more of the Registrants’ results of operations and cash flows and the market prices of their publicly tradedsecurities. Each of the Registrants has disclosed the known material risks that affect its business at this time. However, there may be furtherrisks and uncertainties that are not presently known or that are not currently believed by a Registrant to be material that may adversely affectits performance or financial condition in the future. The Registrants’ most significant risks arise as a consequence of: (1) Generation’s position as a predominantly nuclear generatorselling power into competitive energy markets with a concentration in select regions, and (2) the role of ComEd, PECO and BGE asoperators of electric transmission and distribution systems in three of the largest metropolitan areas in the United States. The Registrants’major risks fall primarily under the following categories: • Market and Financial Risks. Exelon’s and Generation’s market and financial risks include the risk of price fluctuations in thepower markets. Power prices are a function of supply and demand, which in turn are driven by factors such as (1) the price of fuels,in particular the prices of natural gas and coal, which drive the prices that Generation can obtain for the output of its power plants,(2) the rate of expansion of subsidized low-carbon generation in the markets in which Generation’s output is sold, (3) the effects onenergy demand of factors such as weather, economic conditions and implementation of energy efficiency and demand responseprograms, and (4) the impacts of increased competition in the retail channel. 41Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. • Regulatory and Legislative Risks. The Registrants’ regulatory and legislative risks include changes to the laws and regulationsthat govern competitive markets and utility cost recovery, and that drive environmental policy. In particular, Exelon’s andGeneration’s financial performance may be adversely affected by changes that could affect Generation’s ability to sell power into thecompetitive wholesale power markets at market-based prices. In addition, potential regulation and legislation regarding climatechange and renewable portfolio standards could increase the pace of development of wind energy facilities, which could putdownward pressure in some markets on wholesale market prices for electricity from Generation’s nuclear assets, partiallyoffsetting any additional value Exelon and Generation might derive from Generation’s nuclear assets under a carbon constrainedregulatory regime that might exist in the future. Also, regulatory actions in Illinois, Pennsylvania or Maryland could materiallylower returns for ComEd, PECO and BGE, respectively. • Operational Risks. The Registrants’ operational risks include those risks inherent in running the nation’s largest fleet of nuclearpower reactors and large electric and gas distribution systems. The safe and effective operation of the nuclear facilities and the abilityto effectively manage the associated decommissioning obligations as well as the ability to maintain the availability, reliability andsafety of its energy delivery systems are fundamental to Exelon’s ability to protect and grow shareholder value. Additionally, theoperating costs of ComEd, PECO and BGE, and the opinions of customers and regulators of ComEd, PECO and BGE, areaffected by those companies’ ability to maintain the reliability and safety of their energy delivery systems. • Risks Related to the Merger with Constellation and the Pending Master Agreement between Generation and CENG. Asa result of the merger with Constellation that closed on March 12, 2012, Exelon may encounter unexpected difficulties or costs inmeeting commitments it made under various orders and agreements associated with regulatory approvals from the July 29, 2013Master Agreement between Exelon, Generation and subsidiaries of Generation with EDF, EDF Inc. (EDFI) (a subsidiary of EDF)and CENG. Exelon and Generation are subject to the risks that integration of CENG’s nuclear fleet may not achieve anticipatedresults, and that Exelon and Generation may not be able to fully integrate the operations of CENG in the manner expected. A discussion of each of these risk categories and other risk factors is included below. Market and Financial Risks Generation is exposed to depressed prices in the wholesale and retail power markets, which may negatively affect its results ofoperations and cash flows. (Exelon and Generation) Generation is exposed to commodity price risk for the unhedged portion of its electricity generation supply portfolio. As such,Generation’s earnings and cash flows are therefore subject to variability as spot and forward market prices in the markets in which it operatesrise and fall. Price of Fuels: The spot market price of electricity for each hour is generally determined by the marginal cost of supplying the next unitof electricity to the market during that hour. Thus, the market price of power is affected by the market price of the marginal fuel used togenerate the electricity unit. Often, the next unit of electricity will be supplied from generating stations fueled by fossil fuels. Consequently,changes in the market price of fossil fuels often result in comparable changes to the market price of power. For example, the use of newtechnologies to recover natural gas from shale deposits has increased natural gas supply and reserves, placing downward pressure onnatural gas prices and, therefore, on power prices. The continued addition of supply from new alternative generation resources, such as windand solar, whether mandated through RPS or otherwise subsidized or 42Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In addition,further delay or elimination of EPA air quality regulations could prolong the duration for which the cost of pollution from fossil fuel generationis not factored into market prices. Demand and Supply: The market price for electricity is also affected by changes in the demand for electricity and the available supply ofelectricity. Unfavorable economic conditions, milder than normal weather, and the growth of energy efficiency and demand responseprograms can each depress demand. The result is that higher-cost generating resources do not run as frequently, putting downward pressureon electricity market prices. The continued tepid economic environment and growing energy efficiency and demand response initiatives havelimited the demand for electricity in Generation’s markets. In addition, in some markets, the supply of electricity through wind or solargeneration, when combined with other base-load generation such as nuclear, may often exceed demand during some hours of the day,resulting in loss of revenue for base-load generating plants. The risk of increased supply in excess of demand is heightened by continued orincreased RPS mandates or other subsidies, including ITCs and PTCs. Retail Competition: Generation’s retail operations compete for customers in a competitive environment, which affects the margins thatGeneration can earn and the volumes that it is able to serve. In an environment of sustained low natural gas and power prices and lowmarket 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. Increased or more aggressive competition can adversely affectoverall gross margins and profitability in Generation’s retail operations. Sustained low market prices or depressed demand and over-supply could adversely affect Exelon’s and Generation’s results ofoperations and cash flows, and such impacts could be emphasized given Generation’s concentration of base-load electric generating capacitywithin primarily two geographic market regions, namely the Midwest and the Mid-Atlantic. These impacts could adversely affect Exelon’s andGeneration’s ability to fund other discretionary uses of cash such as growth projects or to pay dividends. In addition, such conditions may nolonger support the continued operation of certain generating facilities, which could adversely affect Exelon’s and Generation’s results ofoperations through increased depreciation rates, impairment charges and accelerated future decommissioning costs which may be offset inwhole or in part by reduced operating and maintenance expenses. A slow recovery in market conditions could result in a prolongeddepression of or further decline in commodity prices, including low forward natural gas and power prices and low market volatility, whichcould also adversely affect Exelon’s and Generation’s results of operations, cash flows and financial position. In addition to price fluctuations, Generation is exposed to other risks in the power markets that are beyond its control and maynegatively affect its results of operations. (Exelon and Generation) Credit Risk. In the bilateral markets, Generation is exposed to the risk that counterparties that owe Generation money, or are obligatedto purchase energy or fuel from Generation, will not perform under their obligations for operational or financial reasons. In the event thecounterparties to these arrangements fail to perform, Generation might be forced to purchase or sell energy or fuel in the wholesale marketsat less favorable prices and incur additional losses, to the extent of amounts, if any, 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, thepurpose of which is to spread such risk across all market participants. Generation is also a party to agreements with entities in the energysector that have experienced rating downgrades or other financial difficulties. In addition, Generation’s retail sales subject it to credit riskthrough competitive electricity and natural gas supply activities to serve commercial and industrial companies, governmental entities and 43Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

This risk represents the loss thatmay be incurred due to the nonpayment of a customer’s account balance, as well as the loss from the resale of energy previously committedto serve the customer. Unstable Markets. The wholesale spot markets remain evolving markets that vary from region to region and are still developingpractices and procedures. Problems in or the failure of any of these markets could adversely affect Generation’s business. In addition, asignificant decrease in market participation could affect market liquidity and have a detrimental effect on market stability. The Registrants are potentially exposed to emerging technologies that may over time affect or transform the energy industry,including technologies related to energy generation, distribution and consumption. (Exelon, Generation, ComEd, PECO andBGE) Some of these technologies include, but are not limited to further shale gas development or sources, cost-effective renewable energytechnologies, broad consumer adoption of electric vehicles and energy storage devices. Such developments could lower the price of energy,could affect energy deliveries as customer-owned generation becomes more cost-effective, could require further improvements to ourdistribution systems to address changing load demands and could make portions of our electric system power supply and transmissionand/or distribution facilities obsolete prior to the end of their useful lives. Such technologies could also result in further declines in commodityprices or demand for delivered energy. Each of these factors could materially affect the Registrants’ results of operations, financial position,and cash flows through, among other things, reduced operating revenues, increased operating and maintenance expenses, and increasedcapital expenditures, as well as potential asset impairment charges or accelerated depreciation and decommissioning expenses overshortened remaining asset useful lives. Market performance and other factors may decrease the value of NDT funds and employee benefit plan assets and increase therelated employee benefit plan obligations, which then could require significant additional funding. (Exelon, Generation,ComEd, PECO and BGE) Disruptions in the capital markets and their actual or perceived effects on particular businesses and the greater economy may adverselyaffect the value of the investments held within Generation’s NDTs and Exelon’s employee benefit plan trusts. The Registrants havesignificant obligations in these areas and Exelon and Generation hold substantial assets in these trusts to meet those obligations. The assetvalues are subject to market fluctuations and will yield uncertain returns, which may fall below the Registrants’ projected return rates. Adecline in the market value of the NDT fund investments may increase Generation’s funding requirements to decommission its nuclearplants. A decline in the market value of the pension and other postretirement benefit plan assets will increase the funding requirementsassociated with Exelon’s pension and other postretirement benefit plan obligations. Additionally, Exelon’s pension and other postretirementbenefit plan liabilities are sensitive to changes in interest rates. As interest rates decrease, the liabilities increase, potentially increasingbenefit costs and funding requirements. Changes in demographics, including increased numbers of retirements or changes in lifeexpectancy assumptions or changes to Social Security or Medicare eligibility requirements may also increase the costs and fundingrequirements of the obligations related to the pension and other postretirement benefit plans. If future increases in pension and otherpostretirement costs as a result of reduced plan assets or other factors cannot be recovered, or cannot be recovered in a timely manner, fromComEd, PECO and BGE customers, the results of operations and financial positions of ComEd, PECO and BGE could be negativelyaffected. Ultimately, if the Registrants are unable to manage the investments with the NDT funds and benefit plan assets, and unable tomanage the related benefit plan liabilities, their results of operations, cash flows and financial positions could be negatively affected. 44Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Unstable capital and credit markets and increased volatility in commodity markets may adversely affect the Registrants’businesses in several ways, including the availability and cost of short-term funds for liquidity requirements, the Registrants’ability to meet long-term commitments, Generation’s ability to hedge effectively its generation portfolio, and the competitivenessand liquidity of energy markets; each could adversely affect the Registrants’ financial condition, results of operations and cashflows. (Exelon, Generation, ComEd, PECO and BGE) 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 if internal funds are not available from the Registrants’ respectiveoperations. Disruptions in the capital and credit markets in the United States or abroad can adversely affect the Registrants’ ability to accessthe capital markets or draw on their respective bank revolving credit facilities. The Registrants’ access to funds under their credit facilities isdependent on the ability of the banks that are parties to the facilities to meet their funding commitments. Those banks may not be able tomeet their funding commitments to the Registrants if they experience shortages of capital and liquidity or if they experience excessivevolumes of borrowing requests from the Registrants and other borrowers within a short period of time. The inability to access capital marketsor 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, changes toGeneration’s hedging strategy in order to reduce collateral-posting requirements, or a reduction in dividend payments or other discretionaryuses of cash. In addition, the Registrants have exposure to worldwide financial markets, including Europe. Disruptions in the European marketscould reduce or restrict the Registrants’ ability to secure sufficient liquidity or secure liquidity at reasonable terms. As of December 31, 2013,approximately 30%, or $2.5 billion, of the Registrants’ available credit facilities were with European banks. The credit facilities include $8.4billion in aggregate total commitments of which $6.6 billion was available as of December 31, 2013. There were no borrowings under theRegistrants’ credit facilities as of December 31, 2013. See Note 13 of the Combined Notes to the Consolidated Financial Statements foradditional information on the credit facilities. The strength and depth of competition in competitive energy markets depend heavily on active participation by multiple trading parties,which could be adversely affected by disruptions in the capital and credit markets and legislative and regulatory initiatives that may affectparticipants in commodities transactions. Reduced capital and liquidity and failures of significant institutions that participate in the energymarkets could diminish the liquidity and competitiveness of energy markets that are important to the respective businesses of theRegistrants. Perceived weaknesses in the competitive strength of the energy markets could lead to pressures for greater regulation of thosemarkets or attempts to replace market structures with other mechanisms for the sale of power, including the requirement of long-termcontracts, which could have a material adverse effect on Exelon’s and Generation’s results of operations and cash flows. If any of the Registrants were to experience a downgrade in its credit ratings to below investment grade or otherwise fail tosatisfy the credit standards in its agreements with its trading counterparties, it would be required to provide significantamounts of collateral under its agreements with counterparties and could experience higher borrowing costs. (Exelon,Generation, ComEd, PECO and BGE) Generation’s business is subject to credit quality standards that may require market participants to post collateral for their obligations. IfGeneration were to be downgraded or lose its investment grade credit rating (based on its senior unsecured debt rating) or otherwise fail tosatisfy the credit standards of trading counterparties, it would be required under its hedging arrangements to provide collateral in the form ofletters of credit or cash, which may have a material adverse effect upon its liquidity.

Past financial performance is no guarantee of future results. of collateral required to be provided by Generation at any point in time is dependent on a variety of factors, including (1) the notional amountof the applicable hedge, (2) the nature of counterparty and related agreements, and (3) changes in power or other commodity prices. Inaddition, if Generation were downgraded, it could experience higher borrowing costs as a result of the downgrade. Generation couldexperience a downgrade in its ratings if any of the credit rating agencies concludes that the level of business or financial risk and overallcreditworthiness of the power generation industry in general, or Generation in particular, has deteriorated. Changes in ratings methodologiesby the credit rating agencies could also have a negative impact on the ratings of Generation. ComEd’s operating agreement with PJM contains collateral provisions that are affected by its credit rating and market prices. If certainwholesale market conditions exist and ComEd were to lose its investment grade credit rating (based on its senior unsecured debt rating), itwould be required under the PJM operating agreement to provide collateral in the forms of letters of credit or cash, which may have a materialadverse effect upon its liquidity. Collateral posting will generally increase as market prices rise and decrease as market prices fall. Given therelationship to forward market prices, contract collateral requirements can be volatile. In addition, if ComEd were downgraded, it couldexperience higher borrowing costs as a result of the downgrade. PECO’s and BGE’s operating agreements with PJM and their natural gas procurement contracts contain collateral provisions that areaffected by their credit ratings. If certain wholesale market conditions exist and PECO and BGE were to lose their investment grade creditratings (based on their senior unsecured debt ratings), they would be required to provide collateral in the form of letters of credit or cash,which may have material adverse effects upon their liquidity. PECO’s and BGE’s collateral requirements relating to their natural gas supplycontracts are a function of market prices. Collateral posting requirements for PECO and BGE with respect to these contracts will generallyincrease as forward market prices fall and decrease as forward market prices rise. Given the relationship to forward market prices, contractcollateral requirements can be volatile. In addition, if PECO or BGE were downgraded, they could experience higher borrowing costs as aresult of the downgrade. ComEd, PECO or BGE could experience a downgrade in its ratings if any of the credit rating agencies concludes that the level ofbusiness or financial risk and overall creditworthiness of the utility industry in general, or ComEd, PECO, or BGE in particular, hasdeteriorated. ComEd, PECO or BGE could experience a downgrade if the current regulatory environments in Illinois, Pennsylvania orMaryland, respectively, become less predictable by materially lowering returns for utilities in the applicable state or adopting other measuresto mitigate higher electricity prices. Additionally, the ratings for ComEd, PECO or BGE could be downgraded if their financial results areweakened from current levels due to weaker operating performance or due to a failure to properly manage their capital structure. In addition,changes in ratings methodologies by the agencies could also have a negative impact on the ratings of ComEd, PECO or BGE. ComEd, PECO and BGE conduct their respective businesses and operate under governance models and other arrangements andprocedures intended to assure that ComEd, PECO and BGE are treated as separate, independent companies, distinct from Exelon and otherExelon subsidiaries in order to isolate ComEd, PECO and BGE from Exelon and other Exelon subsidiaries in the event of financial difficultyat Exelon or another Exelon subsidiary. These measures (commonly referred to as “ringfencing”) may help avoid or limit a downgrade in thecredit ratings of ComEd, PECO and BGE in the event of a reduction in the credit rating of Exelon. Despite these ringfencing measures, thecredit ratings of ComEd, PECO or BGE could remain linked, to some degree, to the credit ratings of Exelon. Consequently, a reduction inthe credit rating of Exelon could result in a reduction of the credit rating of ComEd, PECO or BGE, or all three. A reduction in the credit ratingof ComEd, PECO or BGE could have a material adverse effect on ComEd, PECO or BGE, respectively. 46Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. See Liquidity and Capital Resources—Recent Market Conditions and Security Ratings for further information regarding the potentialimpacts of credit downgrades on the Registrants’ cash flows. Generation’s financial performance may be negatively affected by price volatility, availability and other risk factors associatedwith the procurement of nuclear and fossil fuel. (Exelon and Generation) Generation depends on nuclear fuel and fossil fuels to operate its generating facilities. Nuclear fuel is obtained predominantly throughlong-term uranium concentrate supply contracts, contracted conversion services, contracted enrichment services and contracted fuelfabrication services. Coal, natural gas and oil are procured for generating plants through annual, short-term and spot-market purchases. Thesupply markets for nuclear fuel, coal, natural gas and oil are subject to price fluctuations, availability restrictions and counterparty default thatmay negatively affect the results of operations for Generation. Generation’s risk management policies cannot fully eliminate the risk associated with its commodity trading activities. (Exelonand Generation) Generation’s asset-based power position as well as its power marketing, fuel procurement and other commodity trading activitiesexpose Generation to risks of commodity price movements. Generation attempts to manage this exposure through enforcement ofestablished risk limits and risk management procedures. These risk limits and risk management procedures may not work as planned andcannot eliminate all risks associated with these activities. Even when its policies and procedures are followed, and decisions are made basedon projections and estimates of future performance, results of operations may be diminished if the judgments and assumptions underlyingthose decisions prove to be incorrect. Factors, such as future prices and demand for power and other energy-related commodities, becomemore difficult to predict and the calculations become less reliable the further into the future estimates are made. As a result, Generationcannot predict the impact that its commodity trading activities and risk management decisions may have on its business, operating results,cash flows or financial position. Generation buys and sells energy and other products in the wholesale markets and enters into financial contracts to manage risk andhedge various positions in Generation’s power generation portfolio. The proportion of hedged positions in its power generation portfolio maycause volatility in Generation’s future results of operations. Financial performance and load requirements may be adversely affected if Generation is unable to effectively manage its powerportfolio. (Exelon and Generation) A significant portion of Generation’s power portfolio is used to provide power under procurement contracts with ComEd, PECO, BGEand other customers. To the extent portions of the power portfolio are not needed for that purpose, Generation’s wholesale output is sold inthe wholesale power markets. To the extent its power portfolio is not sufficient to meet the requirements of its customers under the relatedagreements, Generation must purchase power in the wholesale power markets. Generation’s financial results may be negatively affected ifit is unable to cost-effectively meet the load requirements of its customers, manage its power portfolio and effectively address the changes inthe wholesale power markets. Challenges to tax positions taken by the Registrants as well as tax law changes and the inherent difficulty in quantifyingpotential tax effects of business decisions, could negatively impact the Registrants’ results of operations and cash flows.(Exelon, Generation, ComEd, PECO and BGE) Corporate Tax Reform. There exists the potential for comprehensive tax reform in the United States that may significantly change thetax rules applicable to U.S. domiciled corporations. Exelon cannot assess what the overall effect of such potential legislation would be on itsresults of operations and cash flows. 47Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The IRS has challenged Exelon’s 1999 tax position on its like-kind exchange transaction.Exelon and the IRS failed to reach a settlement on the like-kind exchange position and Exelon filed a petition on December 13, 2013 toinitiate litigation in the United States Tax Court. Exelon was not required to remit any part of the asserted tax or penalty in order to litigate thelike-kind exchange position. The litigation could take three to five years including appeals, if necessary. As of December 31, 2013, if the IRS is successful in its challenge to the like-kind exchange position, Exelon’s potential cash outflow,including tax and after-tax interest, exclusive of penalties, that could become currently payable may be as much as $840 million, of whichapproximately $305 million would be attributable to ComEd after consideration of Exelon’s agreement to hold ComEd harmless. In additionto attempting to impose tax on the like-kind exchange position, the IRS has asserted penalties for a substantial understatement of tax, whichcould result in an after-tax charge of $87 million to Exelon’s and ComEd’s results of operations should the IRS prevail in asserting thepenalties. The timing effects of the final resolution of the like-kind exchange matter are unknown. See Note 14 of the Combined Notes toConsolidated Financial Statements for additional information. Tax reserves and the recoverability of deferred tax assets. The Registrants are required to make judgments in order to estimatetheir obligations to taxing authorities. These tax obligations include income, real estate, sales and use and employment-related taxes andongoing appeals issues related to these tax matters. These judgments include reserves for potential adverse outcomes regarding taxpositions that have been taken that may be subject to challenge by the tax authorities. The Registrants also estimate their ability to utilize taxbenefits, including those in the form of carryforwards and tax credits. See Notes 1 and 14 of the Combined Notes to Consolidated FinancialStatements for additional information. Increases in customer rates and the impact of economic downturns may lead to greater expense for uncollectible customerbalances. Additionally, increased rates could lead to decreased volumes delivered. Both of these factors may decreaseGeneration’s, ComEd’s, PECO’s and BGE’s results from operations and cash flows. (Exelon, Generation, ComEd, PECO andBGE) ComEd’s, PECO’s and BGE’s current procurement plans include purchasing power through contracted suppliers and in the spotmarket. ComEd’s and PECO’s costs of purchased power are charged to customers without a return or profit component. BGE’s SOS ratescharged to customers recover BGE’s wholesale power supply costs and include an administrative fee which includes a shareholder returncomponent and an incremental cost component. For PECO, purchased natural gas costs are charged to customers with no return or profitcomponent. For BGE, purchased natural gas costs are charged to customers using a MBR mechanism that compares the actual cost of gasto a market index. The difference between the actual cost and the market index is shared equally between shareholders and customers.Purchased power and natural gas prices fluctuate based on their relevant supply and demand. Significantly higher rates related to purchasedpower and natural gas can result in declines in customer usage, lower revenues and potentially additional uncollectible accounts expense forComEd, PECO and BGE. In addition, any challenges by the regulators or ComEd, PECO and BGE as to the recoverability of these costscould have a material effect on the Registrants’ results of operations and cash flows. Also, ComEd’s, PECO’s and BGE’s cash flows can beaffected by differences between the time period when electricity and natural gas are purchased and the ultimate recovery from customers. Further, the impacts of economic downturns on ComEd, PECO and BGE customers and purchased natural gas costs for PECO andBGE customers, such as unemployment for residential customers and less demand for products and services provided by commercial andindustrial customers, and the related regulatory limitations on residential service terminations, may result in an increase in the number ofuncollectible customer balances, which would negatively impact ComEd’s, PECO’s and BGE’s results from operations and cash flows.Generation’s customer supply activities 48Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

As Generation increases its customer supply footprint, economic downturn impacts could negatively affect Generation’sresults from operations and cash flows. See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK forfurther discussion of the Registrants’ credit risk. The effects of weather may impact the Registrants’ results of operations and cash flows. (Exelon, Generation, ComEd, PECOand BGE) Temperatures above normal levels in the summer tend to increase summer cooling electricity demand and revenues, andtemperatures below normal levels in the winter tend to increase winter heating electricity and gas demand and revenues. Weather conditionsdirectly influence the demand for electricity and natural gas and affect the price of energy commodities. Moderate temperatures adverselyaffect the usage of energy and resulting revenues at ComEd and PECO. Due to revenue decoupling, BGE recognizes revenues at MDPSC-approved levels per customer, regardless of what actual distribution volumes are for a billing period, and is not affected by actual weather withthe exception of major storms. Extreme weather conditions or damage resulting from storms may stress ComEd’s, PECO’s and BGE’stransmission and distribution systems, communication systems and technology, resulting in increased maintenance and capital costs andlimiting each company’s ability to meet peak customer demand. These extreme conditions may have detrimental effects on ComEd’s,PECO’s and BGE’s results of operations and cash flows. First and third quarter financial results, in particular, are substantially dependenton weather conditions, and may 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 extentthat weather is warmer in the summer or colder in the winter than assumed, Generation may require greater resources to meet itscontractual commitments. Extreme weather conditions or storms may affect the availability of generation and its transmission, limitingGeneration’s ability to source or send power to where it is sold. In addition, drought-like conditions limiting water usage can impactGeneration’s ability to run certain generating assets at full capacity. These conditions, which cannot be accurately predicted, may have anadverse effect by causing Generation to seek additional capacity at a time when wholesale markets are tight or to seek to sell excess capacityat a time when markets are weak. Certain long-lived assets and other assets recorded on the Registrants’ statements of financial position may become impaired,which would result in write-offs of the impaired amounts. (Exelon, Generation, ComEd, PECO and BGE) Long-lived assets represent the single largest asset class on the Registrants’ statement of financial position. Specifically, long-livedassets account for 59%, 49%, 61%, 66% and 75% of total assets for Exelon, Generation, ComEd, PECO and BGE, respectively, as ofDecember 31, 2013. In addition, the Registrants have significant balances related to unamortized energy contracts. See Notes 4 and 10 of theCombined Notes to Consolidated Financial Statements for additional information on Exelon’s unamortized energy contracts. The Registrantsevaluate the recoverability of the carrying value of long-lived assets to be held and used whenever events or circumstances indicating apotential impairment exist. Factors such as the business climate, including current and future energy and market conditions, environmentalregulation, and the condition of assets are considered when evaluating long-lived assets for potential impairment. An impairment wouldrequire the Registrants to reduce the carrying value of the long-lived asset through a non-cash charge to expense by the amount of theimpairment, and such an impairment could have a material adverse impact on the Registrants’ results of operations. Exelon and Generation have investments in certain generating plant projects, including the CENG nuclear joint venture with a carryingvalue of $1.9 billion as of December 31, 2013. These investments 49Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. were acquired in the March 2012 Constellation transaction, and were recorded as equity method investments on the balance sheet at fairvalue on the merger date as part of purchase accounting. Exelon and Generation continuously monitor for issues that potentially couldimpact future profitability of these equity method investments and which could result in the recognition of an impairment loss if such issuesindicate an other than temporary decline in value. Such impairment could have a material adverse impact on Exelon’s and Generation’sresults of operations. Exelon holds investments in coal-fired plants in Georgia and Texas subject to long-term leases. The investments are accounted for asdirect financing lease investments. The investments represent the estimated residual values of the leased assets at the end of the respectivelease terms. On an annual basis, Exelon reviews the estimated residual values of its direct financing lease investments and records a non-cash impairment charge to expense if the review indicates an other than temporary decline in the fair value of the residual values below theircarrying values. Such an impairment could have a material adverse impact on Exelon’s results of operations. Exelon and ComEd had approximately $2.6 billion of goodwill recorded at December 31, 2013 in connection with the merger betweenPECO and Unicom Corporation, the former parent company of ComEd. Under GAAP, goodwill remains at its recorded amount unless it isdetermined to be impaired, which is generally based upon an annual analysis that compares the implied fair value of the goodwill to itscarrying value. If an impairment occurs, the amount of the impaired goodwill will be written-off, reducing equity. The actual timing andamounts of any goodwill impairments will depend on many sensitive, interrelated and uncertain variables. A successful IRS challenge toExelon’s and ComEd’s like-kind exchange income tax position, adverse regulatory actions such as early termination of EIMA, or changes insignificant assumptions used in estimating ComEd’s fair value (e.g., discount and growth rates, utility sector market performance andtransactions, operating and capital expenditure requirements and the fair value of debt) could result in an impairment. Such an impairmentwould result in a non-cash charge to expense, which could have a material adverse impact on Exelon’s and ComEd’s results of operations. See ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—Critical Accounting Policies and Estimates and Notes 7, 8 and 10 of the Combined Notes to the Consolidated Financial Statements foradditional discussion on long-lived asset and goodwill impairments. The Registrants’ businesses are capital intensive, and their assets may require significant expenditures to maintain and aresubject to operational failure, which could result in potential liability. (Exelon, Generation, ComEd, PECO and BGE) The Registrants’ businesses are capital intensive and require significant investments by Generation in energy generation and byComEd, PECO and BGE in transmission and distribution infrastructure projects. These operational systems and infrastructure have beenin service for many years. Older equipment, even if maintained in accordance with good utility practices, is subject to operational failure,including events that are beyond the Registrants’ control, and may require significant expenditures to operate efficiently. The Registrants’results of operations, financial condition, or cash flows could be adversely affected if they were unable to effectively manage their capitalprojects or raise the necessary capital. Furthermore, operational failure could result in potential liability if such failure results in damage toproperty or injury to individuals. See ITEM 1.

Past financial performance is no guarantee of future results. Exelon and its subsidiaries have guaranteed the performance of third parties, which may result in substantial costs in theevent of non-performance by third parties. In addition, the Registrants have rights under agreements which obligate thirdparties to indemnify the Registrants for various obligations, and the Registrants may incur substantial costs in the event thatthe applicable Registrant is unable to enforce those agreements or the applicable third-party is otherwise unable to perform.(Exelon, Generation, ComEd, PECO and BGE) The Registrants have issued guarantees of the performance of third parties, which obligate one or more of the Registrants or theirsubsidiaries to perform in the event that the third parties do not perform. In the event of non-performance by those third parties, theRegistrants could incur substantial cost to fulfill their obligations under these guarantees. Such performance guarantees could have amaterial impact on the operating results, financial condition, or cash flows of the Registrants. The Registrants have entered into various agreements with counterparties that require those counterparties to reimburse a Registrantand hold it harmless against specified obligations and claims. To the extent that any of these counterparties are affected by deterioration intheir creditworthiness or the agreements are otherwise determined to be unenforceable, the affected Registrant could be held responsible forthe obligations, which could impact that Registrant’s results of operations, cash flows and financial position. In connection with Exelon’s2001 corporate restructuring, Generation assumed certain of ComEd’s and PECO’s rights and obligations with respect to their formergeneration businesses. Further, ComEd and PECO may have entered into agreements with third parties under which the third-party agreedto indemnify ComEd or PECO for certain obligations related to their respective former generation businesses that have been assumed byGeneration as part of the restructuring. If the third-party or Generation experienced events that reduced its creditworthiness or the indemnityarrangement became unenforceable, ComEd or PECO could be liable for any existing or future claims, which could impact ComEd’s orPECO’s results of operations, cash flows and financial position. Generation’s business may be negatively affected by competitive electric generation suppliers. (Exelon and Generation) Because retail customers where Generation serves load can switch from their respective energy delivery company to a competitiveelectric generation supplier for their energy needs, planning to meet Generation’s obligation to provide the supply needed to serveGeneration’s share of an electric distribution company’s default service obligation is more difficult than planning for retail load before theadvent of retail competition. Before retail competition, the primary variables affecting projections of load were weather and the economy. Withretail competition, another major factor is retail customers switching to or from competitive electric generation suppliers. If fewer of suchcustomers switch from its retail load serving counterparties than Generation anticipates, the load that Generation must serve will be greaterthan anticipated, which could, if market prices have increased, increase Generation’s costs (due to its need to go to market to cover itsincremental supply obligation) more than the increase in Generation’s revenues. If more customers from its retail load serving counterpartiesswitch than Generation anticipates, the load that Generation must serve will be lower than anticipated, which could, if market prices havedecreased, cause Generation to lose opportunities in the market. Regulatory and Legislative Risks The Registrants’ generation and energy delivery businesses are highly regulated and could be subject to adverse regulatoryand legislative actions. Fundamental changes in regulation or legislation or violation of tariffs or market rules and anti-manipulation laws, could disrupt the Registrants’ business plans and adversely affect their operations and financial results.(Exelon, Generation, ComEd, PECO and BGE) Substantially all aspects of the businesses of the Registrants are subject to comprehensive Federal or state regulation and legislation.Further, Exelon’s and Generation’s operating results and 51Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. cash flows are heavily dependent upon the ability of Generation to sell power at market-based rates, as opposed to cost-based or othersimilarly regulated rates, and Exelon’s, ComEd’s, PECO’s and BGE’s operating results and cash flows are heavily dependent on the abilityof ComEd, PECO and BGE to recover their costs for the retail purchase and distribution of power to their customers. Similarly, there is riskthat financial market regulations could increase the Registrants’ compliance costs and limit their ability to engage in certain transactions. Inthe planning and management of operations, the Registrants must address the effects of regulation on their businesses and changes in theregulatory framework, including initiatives by Federal and state legislatures, RTOs, exchanges, ratemaking agencies and taxing authorities.Additionally, the Registrants need to be cognizant of rules changes or Registrant actions that could result in potential violation of tariffs,market rules and anti-manipulation laws. Fundamental changes in regulations or other adverse legislative actions affecting the Registrants’businesses would require changes in their business planning models and operations and could adversely affect their results of operations,cash flows and financial position. Regulatory and legislative developments related to climate change and RPS may also significantly affect Exelon’s and Generation’sresults of operations, cash flows and financial positions. Various legislative and regulatory proposals to address climate change throughGHG emission reductions, if enacted, could result in increased costs to entities that generate electricity through carbon-emitting fossil fuels,which could increase the market price at which all generators in a region, including Generation, may sell their output, thereby increasing therevenue Generation could realize from its low-carbon nuclear assets. However, national regulation or legislation addressing climate changethrough an RPS could also increase the pace of development of wind energy facilities in the Midwest, which could put downward pressure onwholesale market prices for electricity from Generation’s Midwest nuclear assets, partially offsetting any additional value Exelon andGeneration might derive from Generation’s nuclear assets under a carbon constrained regulatory regime that might exist in the future.Current state level climate change and renewable regulation is already providing incentives for regional wind development. The Registrantscannot predict when or whether any of these various legislative and regulatory proposals may become law or what their effect will be on theRegistrants. Generation may be negatively affected by possible Federal or state legislative or regulatory actions that could affect the scopeand functioning of the wholesale markets. (Exelon and Generation) Federal and state legislative and regulatory bodies are facing pressures to address consumer concerns, or are themselves raisingconcerns, that energy prices in wholesale markets are too high or insufficient generation is being built because the competitive model is notworking, and, therefore, are considering some form of re-regulation or some other means of reducing wholesale market prices or subsidizingnew generation. Generation is dependent on robust and competitive wholesale energy markets to achieve its business objectives. Approximately 60% of Generation’s generating resources, which include directly owned assets and capacity obtained through long-termcontracts, are located in the area encompassed by PJM. Generation’s future results of operations will depend on 1) FERC’s continuedadherence to and support for, policies that favor the preservation of competitive wholesale power markets, such as PJM’s, and (2) theabsence of material changes to market structures that would limit or otherwise negatively affect market competitiveness. Generation couldalso be adversely affected by state laws, regulations or initiatives designed to reduce wholesale prices artificially below competitive levels or tosubsidize new generation, such as the subsequently dismissed New Jersey Capacity Legislation and the MDPSC’s RFP for new gas-firedgeneration in Maryland. See Note 3 of the Combined Notes to Consolidated Financial Statements for further details related to the New JerseyCapacity Legislation and the Maryland new electric generation requirements. In addition, FERC’s application of its Order 697 and its subsequent revisions could pose a risk that Generation will have difficultysatisfying FERC’s tests for market-based rates. Since Order 697 became 52Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. final in June 2007, Generation has obtained orders affirming Generation’s authority to sell at market-based rates and none denying thatauthority. On December 31, 2013, Generation submitted its triennial application seeking reauthorization to sell at market-based rates in theNortheast region (including PJM, ISO-NY and ISONE). Generation’s previous submission seeking reauthorization to sell at market-basedrates was accepted by FERC on June 22, 2011 for the PJM region. The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank) was enacted into law on July 21, 2010. Its primaryobjective is to eliminate from the financial system the systemic risk that Congress believed was in part the cause of the financial crisis thatunfolded during 2008. Dodd-Frank ushers in a brand new regulatory regime applicable to the over-the-counter (OTC) market for swaps.Generation relies on the OTC swaps markets as part of its program to hedge the price risk associated with its generation portfolio. In April2012, the CFTC issued its rule defining swap dealers and major swap participants. Generation has determined that it will conduct itscommercial hedging business as an end user in a manner that does not require registration as a swap dealer or major swap participant. Notwithstanding the foregoing, Generation will still face additional regulatory obligations under Dodd-Frank, including some reportingrequirements, clearing some additional transactions that it would otherwise enter into over-the-counter, and having to adhere to positionlimits. More fundamentally, however, the total burden that the rules could impose on all market participants could cause liquidity in thebilateral OTC swaps market to decrease substantially. Dodd-Frank may require up to $1 billion of additional collateral requirements atGeneration, to be met with cash rather than letters of credit in a price stressed environment. Generation continues to monitor the rulemakingprocedures and cannot predict the ultimate outcome that the financial reform legislation will have on its results of operations, cash flows orfinancial position. Generation’s affiliation with ComEd, PECO and BGE, together with the presence of a substantial percentage of Generation’sphysical asset base within the ComEd, PECO and BGE service territories, could increase Generation’s cost of doing businessto the extent future complaints or challenges regarding ComEd, PECO and/or BGE retail rates result in settlements or legislativeor regulatory requirements funded in part by Generation. (Exelon and Generation) Generation has significant generating resources within the service areas of ComEd, PECO and BGE and makes significant sales toeach 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 ComEd, PECO and BGE and its sales to each of them. In periodsof rising utility rates, particularly when driven by increased costs of energy production and supply, those officials and advocacy groups mayquestion or challenge costs incurred by ComEd, PECO or BGE, including transactions between Generation, on the one hand, and ComEd,PECO or BGE, on the other hand, regardless of any previous regulatory processes or approvals underlying those transactions. The prospectof such challenges may increase the time, complexity and cost of the associated regulatory proceedings, and the occurrence of suchchallenges may subject Generation to a level of scrutiny not faced by other unaffiliated competitors in those markets. In addition, governmentofficials and legislators may seek ways to force Generation to contribute to efforts to mitigate potential or actual rate increases, throughmeasures such as generation-based taxes and contributions to rate-relief packages. The Registrants may incur substantial costs to fulfill their obligations related to environmental and other matters. (Exelon,Generation, ComEd, PECO and BGE) The businesses which the Registrants operate are subject to extensive environmental regulation and legislation by local, state andFederal authorities. These laws and regulations affect the manner in which the Registrants conduct their operations and make capitalexpenditures including how they handle air and water emissions and solid waste disposal. Violations of these emission and disposal 53Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In addition, the Registrants are subject to liability under these laws for the remediation costsfor environmental contamination of property now or formerly owned by the Registrants and of property contaminated by hazardoussubstances they generate. The Registrants have incurred and expect to incur significant costs related to environmental compliance, siteremediation and clean-up. Remediation activities associated with MGP operations conducted by predecessor companies are one componentof such costs. Also, the Registrants are currently involved in a number of proceedings relating to sites where hazardous substances havebeen deposited and may 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 toaquatic organisms at existing generating stations, requires the retrofitting of cooling water intake structures at Salem or other Exelon powerplants, this development could result in material costs of compliance. Pursuant to discussions with the NJDEP regarding the application ofSection 316(b) to Oyster Creek, Generation agreed to permanently cease generation operations at Oyster Creek by December 31, 2019, tenyears before the expiration of its operating license in 2029. Additionally, Generation is subject to exposure for asbestos-related personal injury liability alleged at certain current and formerly ownedgeneration facilities. Future legislative action could require Generation to make a material contribution to a fund to settle lawsuits for allegedasbestos-related disease and exposure. In some cases, a third-party who has acquired assets from a Registrant has assumed the liability the Registrant may otherwise havefor environmental matters related to the transferred property. If the transferee is unable, or fails, to discharge the assumed liability, aregulatory authority or injured person could attempt to hold the Registrant responsible, and the Registrant’s remedies against the transfereemay be limited by the financial resources of the transferee. See Note 22 of the Combined Notes to Consolidated Financial Statements foradditional information. Changes in ComEd’s, PECO’s and BGE’s respective terms and conditions of service, including their respective rates, aresubject to regulatory approval proceedings and/or negotiated settlements that are at times contentious, lengthy and subject toappeal, which lead to uncertainty as to the ultimate result and which may introduce time delays in effectuating rate changes.(Exelon, ComEd, PECO and BGE) ComEd, PECO and BGE are required to engage in regulatory approval proceedings as a part of the process of establishing the termsand 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 limitingrate increases or even reducing rates. The proceedings generally have timelines that may not be limited by statute. Decisions are subject toappeal, potentially leading to additional uncertainty associated with the approval proceedings. The potential duration of such proceedingscreates a risk that rates ultimately approved by the applicable regulatory body may not be sufficient for ComEd, PECO or BGE to recover itscosts by the time the rates become effective. Established rates are also subject to subsequent prudency reviews by state regulators, wherebyvarious portions of rates can be adjusted, including recovery mechanisms for costs associated with the procurement of electricity or gas,MGP remediation, smart grid infrastructure, and energy efficiency and demand response programs. In certain instances, ComEd, PECO and BGE may agree to negotiated settlements related to various rate matters, customer initiativesor franchise agreements. These settlements are subject to regulatory approval. 54Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. ComEd, PECO and BGE cannot predict the ultimate outcomes of any settlements or the actions by Illinois, Pennsylvania, Maryland orFederal regulators in establishing rates, including the extent, if any, to which certain costs such as significant capital projects will berecovered or what rates of return will be allowed. Nevertheless, the expectation is that ComEd, PECO and BGE will continue to be obligatedto deliver electricity to customers in their respective service territories and will also retain significant POLR and default service obligations toprovide electricity and natural gas to certain groups of customers in their respective service areas who do not choose an alternative supplier.The ultimate outcome and timing of regulatory rate proceedings have a significant effect on the ability of ComEd, PECO and BGE, asapplicable, to recover their costs and could have a material adverse effect on ComEd’s, PECO’s and BGE’s results of operations, cash flowsand financial position. See Note 3 of the Combined Notes to the Consolidated Financial Statements for information regarding rateproceedings. Federal or additional state RPS and/or energy conservation legislation, along with energy conservation by customers, couldnegatively affect the results of operations and cash flows of Generation, ComEd, PECO and BGE. (Exelon, Generation, ComEd,PECO and BGE) Changes to current state legislation or the development of Federal legislation that requires the use of renewable and alternate fuelsources, such as wind, solar, biomass and geothermal, could significantly impact Generation, ComEd, PECO and BGE, especially if timelycost recovery is not allowed. The impact could include increased costs for RECs and purchased power and increased rates for customers. Federal and state legislation mandating the implementation of energy conservation programs that require the implementation of newtechnologies, such as smart meters and smart grid, have increased capital expenditures and could significantly impact ComEd, PECO andBGE, if timely cost recovery is not allowed. Furthermore, regulated energy consumption reduction targets and declines in customer energyconsumption resulting from the implementation of new energy conservation technologies could lead to a decline in the revenues of Exelon,ComEd, and PECO. For additional information, see ITEM 1. BUSINESS “Environmental Regulation-Renewable and Alternative EnergyPortfolio Standards.” The impact of not meeting the criteria of the FASB guidance for accounting for the effects of certain types of regulation could bematerial to Exelon, ComEd, PECO and BGE. (Exelon, ComEd, PECO and BGE) As of December 31, 2013, Exelon, ComEd, PECO and BGE have concluded that the operations of ComEd, PECO and BGE meet thecriteria of the authoritative guidance for accounting for the effects of certain types of regulation. If it is concluded in a future period that aseparable portion of their businesses no longer meets the criteria, Exelon, ComEd, PECO and BGE would be required to eliminate thefinancial statement effects of regulation for that part of their business. That action would include the elimination of any or all regulatory assetsand liabilities that had been recorded in their Consolidated Balance Sheets and the recognition of a one-time extraordinary item in theirConsolidated Statements of Operations. The impact of not meeting the criteria of the authoritative guidance could be material to the financialstatements of Exelon, ComEd, PECO and BGE. At December 31, 2013, the extraordinary gain (loss) could have been as much as $(2.4)billion, $730 million and $ 453 million (before taxes) as a result of the elimination of ComEd’s, PECO’s and BGE’s regulatory assets andliabilities, respectively. Further, Exelon would record a charge against OCI (before taxes) of up to $2.4 billion and $568 million for ComEdand BGE, respectively, related to Exelon’s regulatory assets associated with its defined benefit postretirement plans. Exelon also has aregulatory liability of $45 million (before taxes) associated with PECO’s defined benefit postretirement plans that would result in an increasein OCI if reversed. The impacts and resolution of the above items could lead to an additional impairment of ComEd’s goodwill, which couldbe significant and at least partially offset the extraordinary gain at ComEd discussed above. A significant decrease in equity as a result of anychanges could limit the ability of ComEd, PECO and BGE to pay dividends under Federal 55Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

SeeNotes 1, 3 and 10 of the Combined Notes to Consolidated Financial Statements for additional information regarding accounting for the effectsof regulation, regulatory matters and ComEd’s goodwill, respectively. Exelon and Generation may incur material costs of compliance if Federal and/or state regulation or legislation is adopted toaddress climate change. (Exelon and Generation) Various stakeholders, including legislators and regulators, shareholders and non-governmental organizations, as well as othercompanies in many business sectors, including utilities, are considering ways to address the effect of GHG emissions on climate change. In2009, select Northeast and Mid-Atlantic states implemented a model rule, developed via the RGGI, to regulate CO emissions from fossil-fired generation. RGGI states are working on updated programs to further limit emissions and the EPA has introduced regulation to addressgreenhouse gases from new fossil plants that could potentially impact existing plants. If carbon reduction regulation or legislation becomeseffective, Exelon and Generation may incur costs either to limit further the GHG emissions from their operations or to procure emissionallowance credits. The nature and extent of environmental regulation may also impact the ability of Exelon and its subsidiaries to meet theGHG emission reduction targets of Exelon 2020. For example, more stringent permitting requirements may preclude the construction oflower-carbon nuclear and gas-fired power plants. Similarly, a Federal RPS could increase the cost of compliance by mandating the purchaseor construction of more expensive supply alternatives. For more information regarding climate change, see ITEM 1. BUSINESS “GlobalClimate Change” and Note 22 of the Combined Notes to Consolidated Financial Statements. The Registrants could be subject to higher costs and/or penalties related to mandatory reliability standards, including the likelyexposure of ComEd, PECO, and BGE to the results of PJM’s RTEP and NERC compliance requirements. (Exelon, Generation,ComEd, PECO and BGE) As a result of the Energy Policy Act of 2005, users, owners and operators of the bulk power transmission system, includingGeneration, ComEd, PECO and BGE, are subject to mandatory reliability standards promulgated by NERC and enforced by FERC. Asoperators of natural gas distribution systems, PECO and BGE are also subject to mandatory reliability standards of the U.S. Department ofTransportation. The standards are based on the functions that need to be performed to ensure the bulk power system operates reliably andare guided by reliability and market interface principles. Compliance with or changes in the reliability standards may subject the Registrantsto higher operating costs and/or increased capital expenditures. In addition, the ICC, PAPUC and MDPSC impose certain distributionreliability standards on ComEd, PECO and BGE, respectively. If the Registrants were found not to be in compliance with the mandatoryreliability standards, they could be subject to remediation costs as well as sanctions, which could include substantial monetary penalties. ComEd, PECO and BGE as transmission owners are subject to NERC compliance requirements. NERC provides guidance totransmission owners regarding assessments of transmission lines. The results of these assessments may require ComEd, PECO andBGE to incur incremental capital or operating and maintenance expenditures to ensure their transmission lines meet NERC standards.Uncertainties exist as to the construction of new transmission facilities, their cost and how those costs will be allocated to transmissionsystem participants and customers. In accordance with a FERC order and related settlement, PJM’s RTEP requires the costs of newtransmission facilities to be allocated across the entire PJM footprint for new facilities greater than or equal to 500 kV, and requires costs ofnew facilities less than 500 kV to be allocated to the beneficiaries of the new facilities. Following a remand from the U.S. Court of Appeals forthe Seventh Circuit, FERC reaffirmed its decision related to allocation of new facilities 500 kV and above. That decision is being appealed tothe U.S. Court of Appeals for the Seventh Circuit. This FERC order only applies to facilities included in the PJM RTEP 562Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

For facilities subsequently approved, the costs of new facilities that are double circuit 345 kV or greater than orequal to 500 kV will be allocated 50% across the entire PJM footprint and 50% allocated to identified beneficiaries. Costs for all other facilitieswill be allocated to all identified beneficiaries. This later decision is subject to rehearing by FERC and possible appeal. See Notes 3 and 22 of the Combined Notes to Consolidated Financial Statements for additional information. The Registrants cannot predict the outcome of the legal proceedings relating to their business activities. An adversedetermination could have a material adverse effect on their results of operations, financial positions and cash flows. (Exelon,Generation, ComEd, PECO and BGE) The Registrants are involved in legal proceedings, claims and litigation arising out of their business operations, the most significant ofwhich are summarized in Note 22 of the Combined Notes to Consolidated Financial Statements. Adverse outcomes in these proceedingscould require significant expenditures that could have a material adverse effect on the Registrants’ results of operations. Generation may be negatively affected by possible Nuclear Regulatory Commission actions that could affect the operations andprofitability of its nuclear generating fleet. (Exelon and Generation) Regulatory risk. A change in the Atomic Energy Act or the applicable regulations or licenses may require a substantial increase incapital expenditures or may result in increased operating or decommissioning costs and significantly affect Generation’s results of operationsor financial position. Events at nuclear plants owned by others, as well as those owned by Generation, may cause the NRC to initiate suchactions. As an example, prior to the Fukushima Daiichi accident on March 11, 2011, the NRC had been evaluating seismic risk. After theFukushima Daiichi accident, the NRC’s focus on seismic risk intensified. As part of the NRC Near-Term Task Force (Task Force) review andevaluation of the Fukushima Daiichi accident, the Task Force recommended that plant operators conduct seismic reevaluations. In January2012, the NRC released an updated seismic risk model that plant operators must use in performing the seismic reevaluationsrecommended by the Task Force. These reevaluations could result in the required implementation of additional mitigation strategies ormodifications. Additionally, the Task Force provided recommendations for future regulatory action by the NRC to be taken in the near andlonger term. In response, the NRC issued three immediately effective orders (Tier 1) to commercial reactor licensees operating in the UnitedStates for compliance no later than December 31, 2016. The NRC is currently evaluating the remaining Task Force recommendations andhas not taken action with respect to the Tier 2 and Tier 3 recommendations. Actions to comply with the Task Force recommendations willresult in increased costs and could significantly impact Generation’s results of operations or financial position. See ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—ExelonCorporation, Executive Overview for a more detailed discussion of the Task Force Recommendations. Spent nuclear fuel storage. The approval of a national repository for the storage of SNF, such as the one previously considered atYucca Mountain, Nevada, and the timing of such facility opening, will significantly affect the costs associated with storage of SNF, and theultimate amounts received from the DOE to reimburse Generation for these costs. The NRC’s temporary storage rule (also referred to as the“waste confidence decision”) recognizes that licensees can safely store spent nuclear fuel at nuclear power plants for up to 60 years beyondthe original and renewed licensed operating life of the plants. In June 2012, the United States Court of Appeals for the DC Circuit vacated theNRC’s temporary storage rule on the grounds that the NRC should have conducted a more comprehensive 57Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. environmental review to support the rule. In September 2012, the NRC directed NRC Staff to complete a generic environmental impactstatement and to revise the temporary storage rule which is now not expected until October 3, 2014. Any regulatory action relating to the timing and availability of a repository for SNF may adversely affect Generation’s ability todecommission fully its nuclear units. In accordance with the NWPA and Generation’s contract with the DOE, Generation pays the DOEongoing fees per kWh of net nuclear generation for the cost of SNF disposal. This fee may be adjusted prospectively in order to ensure fullcost recovery. On November 19, 2013, the United States Court of Appeals for the District of Columbia Circuit ordered the DOE to submit toCongress a proposal to reduce the current SNF disposal fee to zero, unless and until there is a viable disposal program. Until such time as anew fee structure is in effect, Generation must continue to pay the current SNF disposal fees. Furthermore, under its contract with the DOE,Generation would be required to pay the DOE a one-time SNF storage fee including interest of approximately $1 billion as of December 31,2013, prior to the first delivery of SNF. Generation currently estimates 2025 to be the earliest date when the DOE will begin accepting SNF,which could be delayed by further regulatory action. See Note 22 of the Combined Notes to Consolidated Financial Statements for additionalinformation on the spent nuclear fuel obligation. License renewals. Generation cannot assure that economics will support the continued operation of the facilities for all or any portionof any renewed license period. If the NRC does not renew the operating licenses for Generation’s nuclear stations or a station cannot beoperated through the end of its operating license, Generation’s results of operations could be adversely affected by increased depreciationrates, impairment charges and accelerated future decommissioning costs, since depreciation rates and decommissioning cost estimatescurrently include assumptions that license renewal will be received. In addition, Generation may lose revenue and incur increased fuel andpurchased power expense to meet supply commitments. As discussed above, in June 2012, the United States Court of Appeals for the DC Circuit vacated the NRC’s temporary storage rule.Generation does not expect the NRC to issue license renewals until the end of 2014, at the earliest. Operational Risks The Registrants’ employees, contractors, customers and the general public may be exposed to a risk of injury due to the natureof the energy industry. (Exelon, Generation, ComEd, PECO and BGE) Employees and contractors throughout the organization work in, and customers and the general public may be exposed to, potentiallydangerous environments near their operations. As a result, employees, contractors, customers and the general public are at risk for seriousinjury, including loss of life. Significant risks include nuclear accidents, dam failure, gas explosions, pole strikes and electric contact cases. Natural disasters, war, acts and threats of terrorism, pandemic and other significant events may adversely affect Exelon’sresults of operations, its ability to raise capital and its future growth. (Exelon, Generation, ComEd, PECO and BGE) Generation’s fleet of nuclear and fossil-fueled power plants and ComEd’s, PECO’s and BGE’s distribution and transmissioninfrastructures could be affected by natural disasters, such as seismic activity, more frequent and more extreme weather events, changes intemperature and precipitation patterns, changes to ground and surface water availability, sea level rise and other related phenomena. Severeweather or other natural disasters could be destructive, which could result in increased costs, including supply chain costs. An extremeweather event within the Registrants’ service areas can also directly affect their capital assets, causing disruption in service to customers 58Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Examples of such events include the June 2012 “Derecho” storm,which interrupted electric service delivery to customers in BGE’s service territory, and the October 2012 category 1 hurricane, HurricaneSandy, which interrupted electric service delivery to customers in PECO’s and BGE’s service territories and resulted in significant costs toPECO and BGE for restoration efforts. Other events include the 9.0 magnitude earthquake and ensuing tsunami experienced by Japan on March 11, 2011, that seriouslydamaged the nuclear units at the Fukushima Daiichi Nuclear Power Station, which are operated by Tokyo Electric Power Co., and the 5.8magnitude earthquake and flooding associated with Hurricane Irene and Tropical Storm Lee that the Mid-Atlantic region of the United Statesexperienced in 2011. These events increase the risk to Generation that the NRC or other regulatory or legislative bodies may change thelaws or regulations governing, among other things, operations, maintenance, licensed lives, decommissioning, SNF storage, insurance,emergency planning, security and environmental and radiological aspects. In addition, natural disasters could affect the availability of asecure and economical supply of water in some locations, which is essential for Generation’s continued operation, particularly the cooling ofgenerating units. Additionally, natural disasters and other events that have an adverse effect on the economy in general may adversely affectthe Registrants’ operations and their ability to raise capital. Exelon does not know the impact that potential terrorist attacks could have on the industry in general and on Exelon in particular. Asowner-operators of infrastructure facilities, such as nuclear, fossil and hydroelectric generation facilities and electric and gas transmission anddistribution facilities, the Registrants face a risk that their operations would be direct targets of, or indirect casualties of, an act of terror. Anyretaliatory military strikes or sustained military campaign may affect their operations in unpredictable ways, such as changes in insurancemarkets and disruptions of fuel supplies and markets, particularly oil. Furthermore, these catastrophic events could compromise the physicalor cyber security of Exelon’s facilities, which could adversely affect Exelon’s ability to manage its business effectively. Instability in thefinancial markets as a result of terrorism, war, natural disasters, pandemic, credit crises, recession or other factors also may result in adecline in energy consumption, which may adversely affect the Registrants’ results of operations and its ability to raise capital. In addition,the implementation of security guidelines and measures has resulted in and is expected to continue to result in increased costs. The Registrants would 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 operateits generating and transmission and distribution assets could be affected, resulting in decreased service levels and increased costs. In addition, Exelon maintains a level of insurance coverage consistent with industry practices against property and casualty lossessubject to unforeseen occurrences or catastrophic events that may damage or destroy assets or interrupt operations. However, there can beno assurance that the amount of insurance will be adequate to address such property and casualty losses. Generation’s financial performance may be negatively affected by matters arising from its ownership and operation of nuclearfacilities. (Exelon and Generation) Nuclear capacity factors. Capacity factors for generating units, particularly capacity factors for nuclear generating units, significantlyaffect Generation’s results of operations. Nuclear plant operations involve substantial fixed operating costs but produce electricity at lowvariable costs due to nuclear fuel costs typically being lower than fossil fuel costs. Consequently, to be successful, Generation mustconsistently operate its nuclear facilities at high capacity factors. Lower capacity factors increase Generation’s operating costs by requiringGeneration to produce additional energy from primarily its fossil 59Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. facilities or purchase additional energy in the spot or forward markets in order to satisfy Generation’s obligations to committed third-partysales, including ComEd, PECO and BGE. These sources generally have higher costs than Generation incurs to produce energy from itsnuclear stations. Nuclear refueling outages. In general, refueling outages are planned to occur once every 18 to 24 months. The total number ofrefueling outages, along with their duration, can have a significant impact on Generation’s results of operations. When refueling outages atwholly and co-owned plants last longer than anticipated or Generation experiences unplanned outages, capacity factors decrease andGeneration faces lower margins due to higher energy replacement costs and/or lower energy sales. Nuclear fuel quality. The quality of nuclear fuel utilized by Generation can affect the efficiency and costs of Generation’s operations.Certain of Generation’s nuclear units have previously had a limited number of fuel performance issues. Remediation actions could result inincreased 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 has toshut down the plant or operate at less than full capacity. If this were to happen, identifying and correcting the causes may require significanttime and expense. Generation may choose to close a plant rather than incur the expense of restarting it or returning the plant to full capacity.In either event, Generation may lose revenue and incur increased fuel and purchased power expense to meet supply commitments. Inaddition, Generation may not achieve the anticipated results under its series of planned power uprates across its nuclear fleet. For plantsoperated but not wholly owned by Generation, Generation may also incur liability to the co-owners. For plants not operated and not whollyowned by Generation, from which Generation receives a portion of the plants’ output, Generation’s results of operations are dependent onthe operational performance of the operators and could be adversely affected by a significant event at those plants. Additionally, poor operatingperformance at nuclear plants not owned by Generation could result in increased regulation and reduced public support for nuclear-fueledenergy, which could significantly affect Generation’s results of operations or financial position. In addition, closure of generating plants ownedby others, or extended interruptions of generating plants or failure of transmission lines, could affect transmission systems that couldadversely affect the sale and delivery of electricity in markets served by Generation. Nuclear major incident risk. Although the safety record of nuclear reactors generally has been very good, accidents and otherunforeseen problems have occurred both in the United States and abroad. The consequences of a major incident can be severe and includeloss of life and property damage. Any resulting liability from a nuclear plant major incident within the United States, owned or operated byGeneration or owned by others, may exceed Generation’s resources, including insurance coverage. Uninsured losses and other expenses,to the extent not recovered from insurers or the nuclear industry, could be borne by Generation and could have a material adverse effect onGeneration’s results of operations or financial position. Additionally, an accident or other significant event at a nuclear plant within the UnitedStates or abroad, owned by others or Generation, may result in increased regulation and reduced public support for nuclear-fueled energyand significantly affect Generation’s results of operations or financial position. Nuclear insurance. As required by the Price-Anderson Act, Generation carries the maximum available amount of nuclear liabilityinsurance. The required amount of nuclear liability insurance is $375 million for each operating site. Claims exceeding that amount arecovered through mandatory participation in a financial protection pool. In addition, the U.S. Congress could impose revenue-raisingmeasures on the nuclear industry to pay claims exceeding the $13.6 billion limit for a single incident. Generation is a member of an industry mutual insurance company, NEIL, which provides property and business interruptioninsurance for Generation’s nuclear operations. In previous years, NEIL has 60Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. made distributions to its members but Generation cannot predict the level of future distributions or if they will occur at all. See Note 22 of theCombined Notes to Consolidated Financial Statements for additional discussion of nuclear insurance. Decommissioning. NRC regulations require that licensees of nuclear generating facilities demonstrate reasonable assurance thatfunds will be available in certain minimum amounts at the end of the life of the facility to decommission the facility. Generation is required toprovide to the NRC a biennial report by unit (annually for Generation’s two units that have been retired) addressing Generation’s ability tomeet the NRC-estimated funding levels including scheduled contributions to and earnings on the decommissioning trust funds. The NRCfunding levels are based upon the assumption that decommissioning will commence after the end of the current licensed life of each unit. Forecasting trust fund investment earnings and costs to decommission nuclear generating stations requires significant judgment, andactual results may differ significantly from current estimates. The performance of capital markets also can significantly affect the value of thetrust funds. Currently, Generation is making contributions to certain trust funds of the former PECO units based on amounts being collectedby PECO from its customers and remitted to Generation. While Generation has recourse to collect additional amounts from PECOcustomers (subject to certain limitations and thresholds), it has no recourse to collect additional amounts from ComEd customers or from theprevious owners of Clinton, TMI Unit No. 1 and Oyster Creek generating stations, if there is a shortfall of funds necessary fordecommissioning. If circumstances changed such that Generation would be unable to continue to make contributions to the trust funds of theformer PECO units based on amounts collected from PECO customers, or if Generation no longer had recourse to collect additionalamounts from PECO customers if there was a shortfall of funds for decommissioning, the adequacy of the trust funds related to the formerPECO units may be negatively affected and Exelon’s and Generation’s results of operations and financial position could be significantlyaffected. See Note 3 of the Combined Notes to Consolidated Financial Statements for additional information. Ultimately, if the investments held by Generation’s NDTs are not sufficient to fund the decommissioning of Generation’s nuclearplants, Generation may be required to take steps, such as providing financial guarantees through letters of credit or parent companyguarantees or making additional contributions to the trusts, which could be significant, to ensure that the trusts are adequately funded andthat current and future NRC minimum funding requirements are met. As a result, Generation’s cash flows and financial position may besignificantly adversely affected. See Note 15 of the Combined Notes to Consolidated Financial Statements for additional information. Generation’s financial performance may be negatively affected by risks arising from its ownership and operation ofhydroelectric facilities. (Exelon and Generation) FERC has the exclusive authority to license most non-Federal hydropower projects located on navigable waterways, Federal lands orconnected to the interstate electric grid. The license for the Conowingo Hydroelectric Project expires August 31, 2014, and the license for theMuddy Run Pumped Storage Project expires on September 1, 2014. Generation cannot predict whether it will receive all the regulatoryapprovals for the renewed licenses of its hydroelectric facilities. If FERC does not issue new operating licenses for Generation’s hydroelectricfacilities or a station cannot be operated through the end of its operating license, Generation’s results of operations could be adversely affectedby increased depreciation rates and accelerated future decommissioning costs, since depreciation rates and decommissioning cost estimatescurrently include assumptions that license renewal will be received. Generation may also lose revenue and incur increased fuel andpurchased power expense to meet supply commitments. In addition, conditions may be imposed as part of the license renewal process thatmay adversely affect operations, may require a substantial increase in capital expenditures or may result in increased operating costs andsignificantly affect Generation’s results of operations or financial 61Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. position. Similar effects may result from a change in the Federal Power Act or the applicable regulations due to events at hydroelectricfacilities owned by others, as well as those owned by Generation. ComEd’s, PECO’s and BGE’s operating costs, and customers’ and regulators’ opinions of ComEd, PECO and BGE,respectively, are affected by their ability to maintain the availability and reliability of their delivery and operational systems.(Exelon, ComEd, PECO and BGE) Failures of the equipment or facilities, including information systems, used in ComEd’s, PECO’s and BGE’s delivery systems caninterrupt the electric transmission and electric and natural gas delivery, which could negatively impact related revenues, and increasemaintenance and capital expenditures. Equipment or facilities failures can be due to a number of factors, including weather or informationsystems failure. Specifically, if the implementation of advanced metering infrastructure, smart grid or other technologies in ComEd’s,PECO’s or BGE’s service territory fail to perform as intended or are not successfully integrated with billing and other information systems,ComEd’s, PECO’s and BGE’s financial condition, results of operations, and cash flows could be adversely affected. Furthermore, if any ofthe financial, accounting, or other data processing systems fail or have other significant shortcomings, ComEd’s, PECO’s or BGE’sfinancial results could be adversely affected. If an employee causes the operational systems to fail, either as a result of inadvertent error or bydeliberately tampering with or manipulating the operational systems, ComEd’s, PECO’s or BGE’s financial results could also be adverselyaffected. In addition, dependence upon automated systems may further increase the risk that operational system flaws or employeetampering or manipulation of those systems will result in losses that are difficult to detect. The aforementioned failures or those of other utilities, including prolonged or repeated failures, can affect customer satisfaction and thelevel of regulatory oversight and ComEd’s, PECO’s and BGE’s maintenance and capital expenditures. Regulated utilities, which arerequired to provide service to all customers within their service territory, have generally been afforded liability protections against claims bycustomers relating to failure of service. Under Illinois law, however, ComEd can be required to pay damages to its customers in somecircumstances involving extended outages affecting large numbers of its customers, and those damages could be material to ComEd’sresults of operations and cash flows. See Note 22 of the Combined Notes to Consolidated Financial Statements for additional informationregarding proceedings related to storm-related outages in ComEd’s service territory. ComEd’s, PECO’s and BGE’s respective ability to deliver electricity, their operating costs and their capital expenditures may benegatively affected by transmission congestion. (Exelon, ComEd, PECO and BGE) Demand for electricity within ComEd’s, PECO’s and BGE’s service areas could stress available transmission capacity requiringalternative routing or curtailment of electricity usage with consequent effects on operating costs, revenues and results of operations. Also,insufficient availability of electric supply to meet customer demand could jeopardize ComEd’s, PECO’s and BGE’s ability to comply withreliability standards and strain customer and regulatory agency relationships. As with all utilities, potential concerns over transmissioncapacity or generation facility retirements could result in PJM or FERC requiring ComEd, PECO and BGE to upgrade or expand theirrespective transmission systems through additional capital expenditures. Failure to attract and retain an appropriately qualified workforce may negatively impact the Registrants’ results of operations.(Exelon, Generation, ComEd, PECO and BGE) Certain events, such as an employee strike, loss of contract resources due to a major event, and an aging workforce without appropriatereplacements, may lead to operating challenges and increased costs for the Registrants. The challenges include lack of resources, loss ofknowledge and a lengthy time 62Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. period associated with skill development. In this case, costs, including costs for contractors to replace employees, productivity costs andsafety costs, may arise. The Registrants are particularly affected due to the specialized knowledge required of the technical and supportemployees for their generation, transmission and distribution operations. If the Registrants are unable to successfully attract and retain anappropriately qualified workforce, their results of operations could be negatively affected. The Registrants are subject to physical and information security risks. (Exelon, Generation, ComEd, PECO and BGE) The Registrants face physical and information security risks as the owner-operators of generation, transmission and distributionfacilities. A security breach of the physical assets or information systems of the Registrants, their competitors, RTOs and ISOs, or regulatorscould impact the operation of the generation fleet and/or reliability of the transmission and distribution system or subject the Registrants tofinancial harm associated with theft or inappropriate release of certain types of information, including sensitive customer data. If a significantbreach occurred, the reputation of Exelon and its customer supply activities may be adversely affected, customer confidence in theRegistrants or others in the industry may be diminished, or Exelon and its subsidiaries may be subject to legal claims, any of which maycontribute to the loss of customers and have a negative impact on the business and/or results of operations. ComEd’s, PECO’s and BGE’sdeployment of smart meters throughout their service territories may increase the risk of damage from an intentional disruption of the systemby third parties. As a requirement of their SGIG grant, the DOE approved PECO’s and BGE’s cyber security plan related to its smart meterdeployment and will review the plan annually through the expiration of the grant. As with most companies in today’s environment, Exelonexperiences attempts by hackers to infiltrate its corporate network. To date there have been no infiltrations that have resulted in loss of data orany significant effects on business operations. Exelon utilizes a dedicated team of cyber security professionals to ensure the protection of itsinformation and ability to conduct business operations. Despite the measures taken by the Registrants to prevent a security breach, theRegistrants cannot accurately assess the probability that a security breach may occur and are unable to quantify the potential impact of suchan event. In addition, new or updated security regulations could require changes in current measures taken by the Registrants or theirbusiness operations and could adversely affect their results of operations, cash flows and financial position. The Registrants may make investments in new business initiatives, including initiatives mandated by regulators, and marketsthat may not be successful, and acquisitions may not achieve the intended financial results. (Exelon, Generation, ComEd,PECO and BGE) Generation continuously looks to invest in new business initiatives and actively participate in new markets. These include, but are notlimited to, unconventional oil and gas exploration and production, residential power and gas sales, solar and wind generation, and managedload response. Such initiatives may involve significant risks and uncertainties, including distraction of management from current operations,inadequate return on capital, and unidentified issues not discovered in the diligence performed prior to launching an initiative or entering amarket. As these markets mature, there may be new market entrants or expansion by established competitors that increase competition forcustomers and resources. Additionally, it is possible that FERC, state public utility commissions or others may impose certain otherrestrictions on such transactions. All of these factors could result in higher costs or lower revenues than expected, resulting in lower thanplanned returns on investment. ComEd, PECO and BGE face risks associated with the Smart Grid mandated regulatory initiative. Theserisks include, but are not limited to, cost recovery, regulatory concerns, cyber security and obsolescence of technology. Due to these risks, noassurance can be given that such initiatives will be successful and will not have a material adverse effect on ComEd’s, PECO’s or BGE’sfinancial results. 63Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Risks Related to the Merger Exelon may encounter unexpected difficulties or costs in meeting commitments it made under various orders and agreementsassociated with regulatory approvals for the Constellation merger. As a result of the process to obtain regulatory approvals required for the Constellation merger, Exelon is committed to variousprograms, contributions, investments and market mitigation measures in several settlement agreements and regulatory approval orders. Itis possible that Exelon may encounter delays, unexpected difficulties or costs in meeting these commitments in compliance with the termsof the relevant agreements and orders. Failure to fulfill the commitments in accordance with their terms could result in increased costs orresult in penalties or fines that could adversely affect Exelon’s financial position and operating results. Risks Related to the Pending Master Agreement with CENG The integration of CENG’s nuclear fleet may not achieve its anticipated results, and Exelon and Generation may not be able tofully integrate the operations of CENG in the manner expected. Exelon, Generation and subsidiaries of Generation entered into a Master Agreement with EDF, EDF Inc. (EDFI) (a subsidiary of EDF)and CENG that will result in Generation operating the CENG nuclear generation fleet. The Master Agreement was entered into with theexpectation that it will result in various benefits, including, among other things, cost savings and operating efficiencies. Achieving theanticipated benefits of the agreement is subject to a number of uncertainties, including whether CENG can be integrated into Generation inan efficient, effective and timely manner. Integration will take place, and additional agreements will be signed, upon receipt of regulatoryapprovals for the transfer of CENG’s nuclear operating licences to Generation. It is possible that the integration process could take longer than anticipated and could result in the loss of valuable employees, thedisruption of Generation’s business, processes and systems or inconsistencies in standards, controls, procedures, practices, policies,valuation models, and compensation arrangements. In addition, Generation may have difficulty addressing possible differences in corporatecultures and management philosophies. Any of these circumstances could adversely affect Generation’s ability to achieve the anticipatedbenefits of the agreement as and when expected. Failure to achieve these anticipated benefits could result in increased costs or decreases inthe amount of expected revenues and could adversely affect Generation’s future business, financial condition, operating results andprospects.

Exelon, Generation, ComEd, PECO and BGE Dividends Under applicable Federal law, Generation, ComEd, PECO and BGE can pay dividends only from retained, undistributed or currentearnings. A significant loss recorded at Generation, ComEd, PECO or BGE may limit the dividends that these companies can distribute toExelon. The Federal Power Act declares it to be unlawful for any officer or director of any public utility “to participate in the making or paying ofany dividends of such public utility from any funds properly included in capital account.” What constitutes “funds properly included in capitalaccount” is undefined in the Federal Power Act or the related regulations; however, FERC has consistently interpreted the provision to allowdividends to be paid as long as (1) the source of the dividends is clearly disclosed, (2) the dividend is not excessive and (3) there is no self-dealing on the part of corporate officials. While these restrictions may limit the absolute amount of dividends that a particular subsidiary maypay, Exelon does not believe these limitations are materially limiting because, under these limitations, the subsidiaries are allowed to paydividends sufficient to meet Exelon’s actual cash needs. Under Illinois law, ComEd may not pay any dividend on its stock unless, among other things, “[its] earnings and earned surplus aresufficient to declare and pay same after provision is made for reasonable and proper reserves,” or unless it has specific authorization from theICC. ComEd has also agreed in connection with a financing arranged through ComEd Financing III that ComEd will not declare dividends onany shares of its capital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debtsecurities issued to ComEd Financing III; (2) it defaults on its guarantee of the payment of distributions on the preferred trust securities ofComEd Financing III; or (3) an event of default occurs under the Indenture under which the subordinated debt securities are issued. No suchevent has occurred. PECO has agreed in connection with financings arranged through PEC L.P. and PECO Trust IV that PECO will not declare dividendson any shares of its capital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinateddebentures 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 DPreferred Securities of PEC L.P. or the preferred trust securities of PECO Trust IV; or (3) an event of default occurs under the Indenture underwhich the subordinated debentures are issued. No such event has occurred. BGE is subject to certain dividend restrictions established by the MDPSC. First, BGE is prohibited from paying a dividend on itscommon shares through the end of 2014. Second, BGE is prohibited from paying a dividend on its common shares if (a) after the dividendpayment, BGE’s equity ratio would be below 48% as calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s seniorunsecured credit rating is rated by two of the three major credit rating agencies below investment grade. Finally, BGE must notify theMDPSC that it intends to declare a dividend on its common shares at least 30 days before such a dividend is paid. There are no otherlimitations on BGE paying common 73Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Exelon Executive Overview Exelon, a utility services holding company, operates through the following principal subsidiaries: • Generation, whose integrated business consists of owned, contracted and investments in electric generating facilities managedthrough customer supply of electric and natural gas products and services, including renewable energy products, risk managementservices and natural gas exploration and production activities. • ComEd, whose business consists of the purchase and regulated retail sale of electricity and the provision of distribution andtransmission services in northern Illinois, including the City of Chicago. • PECO, whose business consists of the purchase and regulated retail sale of electricity and the provision of distribution andtransmission services in southeastern Pennsylvania, including the City of Philadelphia, and the purchase and regulated retail saleof natural gas and the provision of distribution services in the Pennsylvania counties surrounding the City of Philadelphia. • BGE, whose business consists of the purchase and regulated retail sale of electricity and the provision of distribution andtransmission services in central Maryland, including the City of Baltimore, and the purchase and regulated retail sale of natural gasand the provision of distribution services in central Maryland, including the City of Baltimore. Exelon has nine reportable segments consisting of Generation’s six power marketing reportable segments (Mid-Atlantic, Midwest,New England, New York, ERCOT and Other Regions in Generation), ComEd, PECO and BGE. See Note 24 of the Combined Notes toConsolidated Financial Statements for additional information regarding Exelon’s reportable segments. Through its business services subsidiary BSC, Exelon provides its operating subsidiaries with a variety of support services at cost. Thecosts of these services are directly charged or allocated to the applicable operating segments. Additionally, the results of Exelon’s corporateoperations include costs for corporate governance and interest costs and income from various investment and financing activities. Exelon’s consolidated financial information includes the results of its four separate operating subsidiary registrants, Generation,ComEd, PECO and BGE, which, along with Exelon, are collectively referred to as the Registrants. The following combined Management’sDiscussion and Analysis of Financial Condition and Results of Operations is separately filed by Exelon, Generation, ComEd, PECO andBGE. However, none of the Registrants makes any representation as to information related solely to any of the other Registrants. Financial Results. The following consolidated financial results reflect the results of Exelon for year ended December 31, 2013compared to the same period in 2012. The 2012 financial results only include the operations of Constellation and BGE from the date of themerger with Constellation (the Merger), March 12, 2012, through December 31, 2012. All amounts presented below are before the impact ofincome taxes, except as noted. Results in 2013 were unfavorably impacted at Generation by continuing declines in realized power and gas prices, in part driven by theabundance of natural gas supply, continued sluggish demand and subsidized renewable generation; only partially offset by improved returnsat the utilities, and the 78Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The Registrants’ believe that revenue netof purchased power and fuel expense is a useful measurement because it provides information that can be used to evaluate its operational performance. Revenuenet of purchased power and fuel expense is not a presentation defined under GAAP and may not be comparable to other companies’ presentations or deemed moreuseful than the GAAP information provided elsewhere in this report. Exelon’s net income on common stock was $1,719 million for the year ended December 31, 2013 as compared to $1,160 million forthe year ended December 31, 2012, and diluted earnings per average common share were $ 2.00 for the year ended December 31, 2013 ascompared to $1.42 for the year ended December 31, 2012. Operating revenues net of purchased power and fuel expense, which is a non-GAAP measure discussed below, increased by $832million as compared to 2012. The year-over-year increase in operating revenue net of purchased power and fuel expense reflects theinclusion of Constellation and BGE’s results for the full period in 2013 and was primarily due to the following favorable factors: • Decrease in Generation’s amortization expense for the acquired energy contracts recorded at fair value at the merger date of $610million; 79(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. • Increase in BGE’s revenue net of purchased power and fuel expense of $278 million, primarily as a result of the inclusion ofBGE’s results for the full period in 2013, accrual of the residential customer rate credit that was a condition of the MDPSC’sapproval of Exelon’s merger with Constellation in 2012, and the impact of the MDPSC approved electric and natural gasdistribution rate increases that became effective February 23, 2013; • Increase in Generation’s revenue net of purchased power and fuel of $159 million on other activities, including proprietary trading,retail gas, energy efficiency, energy management and demand response, upstream natural gas and the design and construction ofcustomer sited solar facilities, primarily due to the addition of Constellation; and • Increase in ComEd’s revenue net of purchased power expense of $154 million primarily due to increased distribution revenue dueto recovery of increased costs and capital investment and higher allowed ROE pursuant to the formula rate under EIMA and theenactment of Senate Bill 9. The year-over-year increase in operating revenue net of purchased power and fuel expense was partially offset by the followingunfavorable factors: • Decrease in Generation’s electric revenue net of purchased power and fuel expense of $565 million primarily due to lower realizedenergy prices, lower load volume and increased nuclear fuel expense, partially offset by higher capacity revenue, increased nuclearvolumes, and lower energy supply costs as a result of the integration of the energy generation and load serving businessesfollowing the merger; • Reduced revenue net of purchased power and fuel at Generation of $136 million in 2013 associated with the Maryland Clean Coalassets that were sold in November 2012 and lost compensation on the reliability-must-run program with PJM for retired fossilgenerating assets that expired on May 31, 2012; and • Decrease in PECO’s revenue net of purchased power and fuel expense of $11 million primarily due to the decrease in effectiverates due to increased usage per customer across all customer classes, decreased cost recovery for energy efficiency and demandresponse programs, decreased gross receipts tax revenue, and the customer refund in 2013 of the tax cash benefit related to gasproperty distribution repairs. Operating and maintenance expense decreased by $691 million as compared to 2012 primarily due to the following favorable factors: • Decrease in operating and maintenance expense associated with the generating assets retired or divested during 2012 of $442million; • Costs incurred in March 2012 of $216 million and $195 million as part of the Maryland order approving the merger and asettlement with the FERC, respectively; • Decrease in Constellation merger and integration costs of $201 million in 2013; and • Decrease in uncollectible accounts expense of $58 million at ComEd resulting from the timing of regulatory cost recovery andcustomers purchasing electricity from competitive electric generation suppliers. The year-over-year decrease in operating and maintenance expense was partially offset by the following unfavorable factors: • Increase in labor, other benefits, contracting and materials costs of $298 million, primarily due to the addition of BGE andConstellation for the full period in 2013; and • Long-lived asset impairments and related charges of $174 million in 2013, primarily related to Generation’s cancellation of nuclearuprate projects and the impairment of certain wind generating assets. 80Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Depreciation and amortization expense increased by $272 million primarily due to the addition of BGE and Constellation for the fullperiod in 2013, BGE’s and Constellation’s plant balances in 2012, ongoing capital expenditures across the operating companies, thecompletion of wind and solar facilities placed into service in the second half of 2012 and in 2013 at Generation, and increased regulatoryasset amortization related to higher MGP remediation expenditures and higher costs for energy efficiency and demand response programs atComEd and BGE, respectively. The favorable increase in Equity in earnings/loss of unconsolidated affiliates of $101 million was primarily due to higher net incomefrom Generation’s equity investment in CENG in 2013 compared to the same period in 2012 and lower amortization of the basis differenceof Generation’s ownership interest in CENG recorded at fair value in connection with the merger. Interest expense increased by $428 million primarily due to an increase in interest expense at ComEd related to the remeasurement ofExelon’s like-kind exchange tax position in the first quarter of 2013, an increase in debt obligations as a result of the merger and an increasein project financing at Generation in 2013. Exelon’s effective income tax rates for the years ended December 31, 2013 and 2012 were 37.6% and 34.9%, respectively. See Note14 of the Combined Notes to Consolidated Financial Statements for additional information regarding the components of the effective incometax rates. For further detail regarding the financial results for the years ended December 31, 2013 and 2012, including explanation of the non-GAAP measure revenue net of purchased power and fuel expense, see the discussions of Results of Operations by Segment below. Adjusted (non-GAAP) Operating Earnings Exelon’s adjusted (non-GAAP) operating earnings for the year ended December 31, 2013 were $2,149 million, or $2.50 per dilutedshare, compared with adjusted (non-GAAP) operating earnings of $2,330 million, or $2.85 per diluted share, for the same period in 2012. Inaddition to net income, Exelon evaluates its operating performance using the measure of adjusted (non-GAAP) operating earnings becausemanagement believes it represents earnings directly related to the ongoing operations of the business. Adjusted (non-GAAP) operatingearnings exclude certain costs, expenses, gains and losses and other specified items. This information is intended to enhance an investor’soverall understanding of year-to-year operating results and provide an indication of Exelon’s baseline operating performance excluding itemsthat are considered by management to be not directly related to the ongoing operations of the business. In addition, this information is amongthe primary indicators management uses as a basis for evaluating performance, allocating resources, setting incentive compensation targetsand planning and forecasting of future periods.

Past financial performance is no guarantee of future results. As of December 31, 2013, Exelon expects to incur total additional Constellation merger-related expenses in 2014 and 2015 ofapproximately $34 million. Pursuant to the conditions set forth by the MDPSC in its approval of the merger transaction, Exelon committed to provide a package ofbenefits to BGE customers, and make certain investments in the City of Baltimore and the State of Maryland, resulting in an estimateddirect investment in the State of Maryland of approximately $1 billion. The direct investment includes $95 million to $120 million for therequirement to cause construction of a headquarters building in Baltimore for Generation’s competitive energy businesses. On March 20,2013, Generation signed a twenty-year lease agreement that is contingent upon the developer obtaining financing for the construction of thebuilding. Once required approvals are received and financing condition is satisfied, construction of the building will commence. The buildingis expected to be ready for occupancy in two years following commencement of construction. The direct investment estimate also includes$625 million in expenditures relating to the development of 285-300 MW of new electric generation facilities in Maryland (expected to becompleted over the next ten years). Exelon’s Strategy and Outlook for 2014 and Beyond Exelon’s value proposition and competitive advantage come from its scope and scale across the energy value chain and its corestrengths of operational excellence and financial discipline. On March 12, 2012, the Exelon and Constellation merger was completed. The merger creates incremental strategic value by matchingExelon’s clean generation fleet with Constellation’s leading customer-facing platform, as well as creating economies of scale throughexpansion across the energy value chain. Exelon supports customer switching to alternative electric generation suppliers and the addition ofConstellation’s competitive retail operations provides another outlet for Exelon to grow its business in competitive markets. Generation’s electricity generation strategy is to pursue opportunities that provide generation to load matching and that diversify thegeneration fleet by expanding Generation’s regional and technological footprint. Generation leverages its energy generation portfolio toensure delivery of energy to both wholesale and retail customers under long-term and short-term contracts, and in wholesale power markets.Generation’s customer facing activities foster development and delivery of other innovative energy-related products and services for itscustomers. Generation operates in well-developed energy markets and employs an integrated hedging strategy to manage commodity pricevolatility. Its generation fleet, including its nuclear plants which consistently operate at high capacity factors, also provide geographic andsupply source diversity. These factors help mitigate the current challenging conditions in competitive energy markets. Exelon’s utility strategy is to improve reliability and operations and enhance the customer experience, while ensuring ratemakingmechanisms provide the utilities fair financial returns. Exelon seeks to leverage its scale and expertise across the utilities platform throughenhanced standardization and sharing of best practices to achieve improved operational and financial results. Combined, the utilities plan toinvest approximately $15 billion over the next five years in smart meter technology, transmission projects, gas infrastructure, and electricsystem improvement projects, providing greater reliability and improved service for our customers and a stable return for the company. Exelon’s financial priorities are to maintain investment grade credit metrics at each of Exelon, Generation, ComEd, PECO and BGE,and to return value to Exelon’s shareholders with a sustainable dividend throughout the energy commodity market cycle and throughearnings growth from attractive investment opportunities. 84Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. In pursuing its strategies, Exelon has exposure to various market and financial risks, including the risk of price fluctuations in thepower markets. Power prices are a function of supply and demand, which in turn are driven by factors such as (1) the price of fuels, inparticular, the prices of natural gas and coal, which drive the market prices that Generation can obtain for the output of its power plants,(2) the rate of expansion of subsidized low-carbon generation in the markets in which Generation’s output is sold, (3) the effects on energydemand due to factors such as weather, economic conditions and implementation of energy efficiency and demand response programs, and(4) the impacts of increased competition in the retail channel. Exelon continues to assess infrastructure, operational, commercial, policy, andlegal solutions to these market pricing issues. 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 inExelon’s revenues. Since the third quarter of 2011, forward natural gas prices for 2014 and 2015 have declined significantly; in part reflectingan increase in supply due to strong natural gas production (due to shale gas development). Subsidized Generation. The rate of expansion of subsidized low-carbon generation such as wind and solar energy in the markets inwhich Generation’s output is sold can negatively impact wholesale power prices, and in turn, Generation’s results of operations. Various states have implemented or proposed legislation, regulations or other policies to subsidize new generation development, whichmay result in artificially depressed wholesale energy and capacity prices. For example, the New Jersey legislature enacted into law inJanuary 2011, the Long Term capacity Pilot Program (LCAPP). LCAPP provides eligible generators with 15-year fixed contracts for the sale ofcapacity in the PJM capacity market. Under LCAPP, the local utilities in New Jersey are required to pay (or receive) the difference betweengenerators receive in the capacity market and the price guaranteed under the 15 year contract. New Jersey ultimately selected three proposalsto participate in LCAPP and build new generation in the state. In addition, on April 12, 2012, the MDPSC issued an order directing theMaryland electric utilities to enter into a 20-year contract for differences (CfD) with CPV Maryland, LLC (CPV), under which CPV willconstruct an approximately 700 MW combined cycle gas turbine in Waldorf, Maryland, that it projected will be in commercial operation byJune 1, 2015. CPV has subsequently sought to extend that date. The CfD mandates that utilities (including BGE) pay (or receive) thedifference between CPV’s contract price and the revenues it receives for capacity and energy from clearing the unit in the PJM capacitymarket. Exelon and others filed a complaint in federal district court challenging the constitutionality and other aspects of the New Jerseylegislation. Similarly, Exelon and others are also challenging the selection of the three generation developers in New Jersey state courtproceedings and the MDPSC actions in Maryland state court. On October 25, 2013, the U.S. District Court in New Jersey issued a judgmentorder finding that the New Jersey legislation violates the Supremacy Clause of the United States Constitution and the New Jersey SOCAcontract is unenforceable. Similarly, on October 24, 2013, the U.S. District Court in Maryland issued a judgment order finding that theMDPSC’s Order directing BGE and two other Maryland electric distribution companies to enter into a CfD violates the Supremacy Clause ofthe United States Constitution, as described in Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements. Inaddition, on October 1, 2013, a Maryland State Circuit Court upheld the MDPSC Orders as being within the MDPSC’s statutory authorityunder Maryland state law. This decision is separate from the judgment in the federal litigation that the MDPSC Order is unconstitutional andthe CfD unenforceable under federal law. The federal judgment, if upheld, would prevent enforcement of the CfD even if the Circuit Courtdecision stands. The non-prevailing parties have sought appeals in federal appellate court in both the New Jersey and 85Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Maryland federal litigation. Finally, on October 23, 2013, the New Jersey state court dismissed the New Jersey state proceeding withoutprejudice, subject to the final outcome of the New Jersey federal litigation. As required under their contracts, two of the New Jersey generator developers and one in Maryland offered and cleared in PJM’scapacity market auctions held in May 2012 and 2013. In addition, CPV has announced its intention to move forward with construction of itsNew Jersey plant, with or without the challenged state subsidy. Nonetheless to the extent that the state-required customer subsidies areincluded under their respective contracts, Exelon believes that these projects may have artificially suppressed capacity prices in PJM in theseauctions and may continue to do so in future auctions to the detriment of Exelon’s market driven position. While the U.S. District Courtdecisions in Maryland and New Jersey are positive developments, continuation of these state efforts, if successful and unabated by aneffective minimum offer price rule (MOPR), could continue to result in artificially depressed wholesale capacity and/or energy prices. Otherstates could seek to establish programs, which could substantially impact Exelon’s market driven position and could have a significant effecton Exelon’s financial results of operations, financial position and cash flows. PJM’s capacity market rules include a MOPR, which is intended to preclude sellers from artificially suppressing the competitive pricesignals for generation capacity. However, as described above, Exelon does not believe that the existing MOPR will work effectively withrespect to generator developers who have a state-sponsored subsidy and has concerns with certain other aspects of PJM’s rules related to thecapacity auction. Accordingly, Exelon is working with other market stakeholders on several proposed changes to the PJM tariff aimed atensuring that capacity resources (including those with state-sponsored subsidy contracts, excessive imported capacity resources and certainlimited availability demand response resources) cannot inappropriately affect capacity auction prices in PJM. See Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information on theMaryland Order. Exelon remains active in advocating for competitive markets, opposing policies that ask either taxpayers or consumers to subsidize orgive preferential treatment to specific generation providers or technologies, or that would threaten the reliability and value of the integratedelectricity grid. Energy Demand. The continued tepid economic environment and growing energy efficiency initiatives have limited the demand forelectricity across each of the Exelon utility companies. ComEd is projecting load volumes to decrease by 0.2% in 2014 compared to 2013,while PECO and BGE are projecting an increase of 0.3% and 0.6%, respectively, in 2014 compared to 2013. Retail Competition. Generation’s retail operations compete for customers in a competitive environment, which affect the margins thatGeneration can earn and the volumes that it is able to serve. Recently, sustained low forward natural gas and power prices and low marketvolatility have caused retail competitors to aggressively pursue market share, and wholesale generators (including Generation) to use theirretail operations to hedge generation output. These factors have adversely affected overall gross margins and profitability in Generation’sretail operations. Strategic Policy Alignment Exelon routinely reviews its hedging policy, dividend policy, operating and capital costs, capital spending plans, strength of its balancesheet and credit metrics, and sufficiency of its liquidity position, by performing various stress tests with differing variables, such ascommodity price movements, increases in margin-related transactions, changes in hedging practices, and the impacts of hypothetical creditdowngrades. 86Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Exelon’s board of directors declared the first quarter 2013 dividend of $0.525 per share, and in response to low forward energy pricesand weaker financial expectations, among other factors, approved a revised dividend policy going forward. The first quarter dividend was paidon March 8, 2013 to shareholders of record on February 19, 2013 and was based on Exelon’s previous dividend of $2.10 per share on anannualized basis. The second, third and fourth quarter dividends were based on Exelon’s new dividend policy of $0.31 per share quarterlydividend ($1.24 per share on an annualized basis). All future quarterly dividends require approval by Exelon’s board of directors. Exelon and Generation evaluate the economic viability of each of their generating units on an ongoing basis. Decisions regarding thefuture of economically challenged generating assets will be based primarily on the economics of continued operation of the individual plants.If Exelon and Generation do not see a path to sustainable profitability in any of their plants, Exelon and Generation will take steps to retirethose plants to avoid sustained losses. Retirement of plants could materially affect Exelon’s and Generation’s results of operations, financialposition, and cash flows through among other things, potential impairment charges, accelerated depreciation and decommissioningexpenses over the plants remaining useful lives, and ongoing reductions to operating revenues, operating and maintenance expenses, andcapital expenditures. 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 marketprice volatility. Generation is exposed to commodity price risk associated with the unhedged portion of its electricity portfolio. Generationenters into non-derivative and derivative contracts, including financially-settled swaps, futures contracts and swap options, and physicaloptions and physical forward contracts, all with credit-approved counterparties, to hedge this anticipated exposure. Generation has hedges inplace that significantly mitigate this risk for 2014 and 2015. However, Generation is exposed to relatively greater commodity price risk in thesubsequent years with respect to which a larger portion of its electricity portfolio is currently unhedged. As of December 31, 2013, thepercentage of expected generation hedged for the major reportable segments was 92%-95%, 62%-65% and 30%-33% for 2014, 2015, and2016, respectively. The percentage of expected generation hedged is the amount of equivalent sales divided by the expectedgeneration. Expected generation represents the amount of energy estimated to be generated or purchased through owned or contractedcapacity. Equivalent sales represent all hedging products, which include economic hedges and certain non-derivative contracts includingGeneration’s sales of energy to ComEd, PECO and BGE relating to their respective retail load obligations. Generation has been and willcontinue to be proactive in using hedging strategies to mitigate commodity price risk in subsequent years as well. Generation procures coal, oil and natural gas through long-term and short-term contracts and spot-market purchases. Nuclear fuel isobtained predominantly through long-term uranium concentrate supply contracts, contracted conversion services, contracted enrichmentservices and contracted fuel fabrication services. The supply markets for uranium concentrates and certain nuclear fuel services, coal, oil andnatural gas are subject to price fluctuations and availability restrictions. Supply market conditions may make Generation’s procurementcontracts subject to credit risk related to the potential non-performance of counterparties to deliver the contracted commodity or service at thecontracted prices. Approximately 60% of Generation’s uranium concentrate requirements from 2014 through 2018 are supplied by threeproducers. In the event of non-performance by these or other suppliers, Generation believes that replacement uranium concentrates can beobtained, although at prices that may be unfavorable when compared to the prices under the current supply agreements. Non-performance bythese counterparties could have a material adverse impact on Exelon’s and Generation’s results of operations, cash flows and financialposition. ComEd, PECO and BGE mitigate such exposure through regulatory mechanisms that allow them to recover procurement costsfrom retail customers. 87Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Growth Opportunities Exelon is currently pursuing growth in both the utility and generation businesses focused primarily on smart meter and smart gridinitiatives at the utilities and on renewables development and the nuclear uprate program at Generation. The utilities also anticipate makingsignificant future investments in infrastructure modernization and improvement initiatives. Management continually evaluates growthopportunities aligned with Exelon’s existing businesses in electric and gas distribution, electric transmission, generation, customer supply ofelectric and natural gas products and services, and natural gas exploration and production activities, leveraging Exelon’s expertise in thoseareas. Transmission Development Project. Exelon and AEP Transmission Holding Company, LLC (AEP) are working collaboratively todevelop an extra high-voltage transmission project from the western Ohio border through Indiana to the northern portion of Illinois. Referredto as the Reliability Interregional Transmission Extension (RITE) Line project, the project is expected to strengthen the high-voltagetransmission system and improve overall system reliability. RITELine Illinois, LLC (RITELine Illinois) and RITELine Indiana, LLC(RITELine Indiana) have been formed as project companies to develop and own the project. RITELine Illinois will own the transmissionassets located in Illinois and is owned 75% by ComEd and 25% by RITELine Transmission Development Company, LLC (RTD). RITELineIndiana will own the transmission assets located in Indiana and is owned by AEP (75%) and RTD (25%). Exelon Transmission Company,LLC and AEP each own 50% of RTD. The total cost of the RITE Line project is expected to be approximately $1.6 billion, with the Illinoisportion of the line expected to cost approximately $1.2 billion. The ultimate cost and scope of the project are dependent on a number of factors,including RTO requirements, interregional transmission planning process requirements, state siting requirements, routing of the line, andequipment and commodity costs. Exelon and AEP are currently pursuing the project and other segments that are electrically equivalent innature for inclusion in interregional planning process between PJM and MISO; if approved through that process, the project would then needto be approved through the respective planning processes of PJM and MISO. On July 18, 2011, RITELine Illinois and RITELine Indiana filed at FERC for incentive rates and a formula rate for the RITE Lineproject. On October 14, 2011, FERC issued an order on the incentive and formula rate filing. The order grants a base rate of return oncommon equity of 9.9%, plus a 50 basis point adder for the project being in a RTO and a 100 basis point adder for the risks and challenges ofthe project, resulting in a total rate of return on common equity of 11.4%. The order grants a hypothetical capital structure of 45% debt and55% equity until any part of the project enters commercial operations. The order also grants 100% recovery for construction work in progress,100% recovery for abandonment, if the line is abandoned through no fault of the RITELine developers, and the ability to treat pre-constructioncosts as a regulatory asset. All incentives, including the abandonment incentive, are contingent on inclusion of the project in the PJM RTEP.The RITELine companies filed for rehearing on several rate of return on common equity issues and argued that the right to collect abandonedcosts should not be subject to the project being included in the RTEP. The RITELine companies also made a compliance filing as called for inthe October 14, 2011 Order. FERC accepted this filing on March 16, 2012. Smart Meter and Smart Grid Initiatives. ComEd’s Smart Meter and Smart Grid Investments. ComEd plans to invest approximately $1.3 billion on smart meters and smartgrid under EIMA, including $1.0 billion through the AMI Deployment Plan. On June 5, 2013, the ICC issued an interim order approvingComEd’s accelerated AMI deployment plan consistent with the provisions of Senate Bill 9. The deployment plan provides for the installationof 4 million electric smart meters, of which more than 60,000 meters were installed by the end of 2013. PECO’s Smart Meter and Smart Grid Investments. In 2010, the PAPUC approved PECO’s Smart Meter Procurement andInstallation Plan, under which PECO will install more than 1.6 million smart 88Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

PECO plans to spend up to a total of $595 million and $120 million on its smart meter and smart grid infrastructure, respectively, ofwhich $200 million will be funded by SGIG. BGE Smart Grid Initiative. In August 2010, the MDPSC approved a comprehensive smart grid initiative for BGE which includes theplanned installation of 2 million electric and gas smart meters at an expected total cost of approximately $480 million, before considering the$200 million SGIG for smart grid and other related initiatives. See Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information on the SmartMeter and Smart Grid Initiatives. Generation Renewable Development. On September 30, 2011, Exelon announced the completion of its acquisition of all of theinterests in Antelope Valley, a 230-MW solar photovoltaic (PV) project under development in northern Los Angeles County, California, fromFirst Solar, Inc., which is developing, building, operating, and maintaining the project. The first portion of the project began operations inDecember 2012, with six additional blocks coming online in 2013. Exelon has been informed by First Solar of issues relating to delays in thecertification of certain components relating to the final two blocks of the project, which will delay commercial operation of these two blocksuntil the first half of 2014. The delay will not have a material financial effect on Exelon. Exelon expects the project to be in full commercialoperation in the first half of 2014. The acquisition supports the Exelon commitment to renewable energy as part of Exelon 2020. The projecthas a 25-year PPA with Pacific Gas & Electric Company for the full output of the plant, which has been approved by the CPUC. Uponcompletion, the facility will add 230 MWs to Generation’s renewable generation fleet. Total capitalized costs for the facility are expected to beapproximately $1.1 billion. Total capitalized costs incurred through December 31, 2013 were approximately $968 million. In addition,Generation constructed and placed into service 400 MWs of additional wind generation in 2012 at a cost of $710 million and another 50 MWwill be added to Generation’s wind portfolio in 2014 with the expansion of its Beebe project in Michigan, the output of which will be fullycontracted under a 20-year PPA. Nuclear Uprate Program. Generation is engaged in individual projects as part of a planned power uprate program across its nuclearfleet. When economically viable, the projects take advantage of new production and measurement technologies, new materials andapplication of expertise gained from a half-century of nuclear power operations. Based on ongoing reviews, the nuclear uprateimplementation plan was adjusted during 2013 to cancel certain projects. The Measurement Uncertainty Recapture uprate projects at theDresden and Quad Cities nuclear stations were cancelled as a result of the cost of additional plant modifications identified during final designwork which, when combined with then current market conditions, made the projects not economically viable. Additionally, the marketconditions prompted Generation to cancel the previously deferred extended power uprate projects at the LaSalle and Limerick nuclearstations. During 2013, Generation recorded a pre-tax charge to operating and maintenance expense and interest expense of approximately$111 million and $8 million, respectively, to accrue remaining costs and reverse the previously capitalized costs. Under the nuclear uprate program, Generation has placed into service projects representing 316 MWs of new nuclear generation at acost of $952 million, which has been capitalized to property, plant and equipment on Exelon’s and Generation’s consolidated balance sheets.At December 31, 2013, Generation has capitalized $203 million to construction work in progress within property, plant and equipment fornuclear uprate projects expected to be placed in service by the end of 2016, consisting of 200 MWs of new nuclear generation, that are in theinstallation phase across four nuclear stations; Peach Bottom in Pennsylvania and Byron, Braidwood and Dresden in Illinois. The remainingspend associated with these projects is expected to be approximately $300 million through the end of 2016. Generation believes that it isprobable that these projects will be completed. If a project is expected not to be completed as planned, previously capitalized costs will bereversed through earnings as a charge to operating and maintenance expense and interest. 89Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Liquidity Each of the Registrants annually evaluates its financing plan, dividend practices and credit line sizing, focusing on maintaining itsinvestment grade ratings while meeting its cash needs to fund capital requirements, retire debt, pay dividends, fund pension and otherpostretirement benefit obligations and invest in new and existing ventures. The Registrants expect cash flows to be sufficient to meetoperating expenses, financing costs and capital expenditure requirements. Exelon, Generation, ComEd, PECO and BGE have unsecured syndicated revolving credit facilities with aggregate bank commitmentsof $0.5 billion, $5.3 billion, $1.0 billion, $0.6 billion and $0.6 billion, respectively. Generation also has bilateral credit facilities with aggregatemaximum availability of $0.4 billion. Exposure to Worldwide Financial Markets. Exelon has exposure to worldwide financial markets. The ongoing European debt crisishas contributed to the instability in global credit markets. Further disruptions in the European markets could reduce or restrict the Registrants’ability to secure sufficient liquidity or secure liquidity at reasonable terms. As of December 31, 2013, approximately 30%, or $2.5 billion, ofthe Registrants’ aggregate total commitments were with European banks. The credit facilities include $8.4 billion in aggregate totalcommitments of which $6.6 billion was available as of December 31, 2013. There were no borrowings under the Registrants’ credit facilitiesas of December 31, 2013. See Note 13—Debt and Credit Agreements of the Combined Notes to the Consolidated Financial Statements foradditional information on the credit facilities. February 5, 2014 Winter Ice Storm. On February 5, 2014, a winter storm which brought a mix of snow, ice and freezing rain to theregion interrupted electric service delivery to nearly 715,000 customers in PECO’s service territory. Restoration efforts are continuing and willinclude significant costs associated with employee overtime, support from other utilities and incremental equipment, contracted treetrimming crews and supplies. PECO estimates that restoration efforts will result in $60 million to $80 million of incremental operating andmaintenance expense and $30 million to $40 million of incremental capital expenditures for the first quarter of 2014. Tax Matters See Note 14—Income Taxes of the Combined Notes to Consolidated Financial Statements for additional information. Environmental Legislative and Regulatory Developments. Exelon supports the promulgation of certain environmental regulations by the U.S. EPA, including air, water and waste controls forelectric generating units. See discussion below for further details. The air and waste regulations will have a disproportionate adverse impacton fossil-fuel power plants, requiring significant expenditures of capital and variable operating and maintenance expense, and will likelyresult in the retirement of older, marginal facilities. Due to their low emission generation portfolios, Generation and CENG will not besignificantly directly affected by these regulations, representing a competitive advantage relative to electric generators that are more reliant onfossil-fuel plants. Various bills have been introduced in the U.S. Congress that would prohibit or impede the U.S. EPA’s rulemaking efforts.The timing of the consideration of such legislation is unknown. Air Quality. In recent years, the U.S. EPA has been implementing a series of increasingly stringent regulations under the Clean Air Actrelating to NAAQS for conventional air pollutants (e.g., NO, SO and particulate matter) as well as stricter technology requirements tocontrol HAPs (e.g., acid gases, mercury and other heavy metals) from electric generation units. The U.S. EPA continues to review andupdate its NAAQS with a tightened particulate matter NAAQS issued in December 2012 and a review 90x2Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. of the current 2008 ozone NAAQS that is expected to result in a proposed revision of the ozone NAAQS sometime in fall 2014. Theseupdates will potentially result in more stringent emissions limits on fossil-fuel electric generating stations. There continues to be oppositionamong fossil-fuel generation owners to the potential stringency and timing of these air regulations. In July 2011, the U.S. EPA published CSAPR and in June 2012, it issued final technical corrections. CSAPR requires 28 upwindstates in the eastern half of the United States to significantly improve air quality by reducing power plant emissions that cross state lines andcontribute to ground-level ozone and fine particle pollution in downwind states. On August 21, 2012, a three-judge panel of the D.C. CircuitCourt held that the U.S. EPA had exceeded its authority in certain material aspects with respect to CSAPR and vacated the rule andremanded it to the U.S. EPA for further rulemaking consistent with its decision. The Court also ordered that CAIR remain in effect pendingfinalization of CSAPR on remand. Until the U.S. EPA re-issues CSAPR, Exelon cannot determine the impacts of the rule, including any thatwould impact power prices. In June 2013, the U.S. Supreme Court granted the U.S. EPA’s petition to review the D.C. Circuit Court’sCSAPR decision. Oral argument was held on December 10, 2013. A decision is expected sometime during 2014. On December 16, 2011, the U.S. EPA signed a final rule to reduce emissions of toxic air pollutants from power plants and signedrevisions to the NSPS for electric generating units. The final rule, known as MATS, requires coal-fired electric generation plants to achievehigh removal rates of mercury, acid gases and other metals. To achieve these standards, coal units with no pollution control equipmentinstalled (uncontrolled coal units) will have to make capital investments and incur higher operating expenses. It is expected that owners ofsmaller, older, uncontrolled coal units will retire the units rather than make these investments. Coal units with existing controls that do notmeet the MATS rule may need to upgrade existing controls or add new controls to comply. Owners of oil units not currently meeting theproposed emission standards may choose to convert the units to light oils or natural gas, install control technologies, or retire the units.Numerous entities have challenged MATS in the D.C. Circuit Court, and Exelon was granted permission by the Court to intervene insupport of the rule. A decision by the Court will not occur until 2014. The outcome of the appeal, and its impact on power plant operators’investment and retirement decisions, is uncertain. The cumulative impact of these air regulations could be to require power plant operators to expend significant capital to install pollutioncontrol technologies, including wet flue gas desulfurization technology for SO and acid gases, and selective catalytic reduction technology forNO. Exelon, along with the other co-owners of Conemaugh Generating Station are moving forward with plans to improve the existingscrubbers and install Selective Catalytic Reduction (SCR) controls to meet the mercury removal requirements of MATS by January 1,2015. In addition, Keystone already has SCR and Flue-gas desulfurization (FGD) controls in place. On January 15, 2013, EPA issued a final rule for NSPS and National Emissions Standards for Hazardous Air Pollutants (NESHAP)for reciprocating internal combustion engines (RICE NESHAP/NSPS). The final rule allows diesel backup generators to operate for up to 100hours annually under certain emergency circumstances without meeting emissions limitations, but requires units that operate over 15 hoursto burn low sulfur fuel and report key engine information. The final rule eliminates after May 2014 the 50 hour exemption for peak shavingand other non-emergency demand response that was included in the proposed rule and, therefore, is not expected to result in additionalmegawatts of demand response to be bid into the PJM capacity auction. In the absence of Federal legislation, the U.S. EPA is also moving forward with the regulation of GHG emissions under the Clean AirAct. The U.S. EPA is addressing the issue of carbon dioxide (CO2) emissions regulation for new and existing electric generating unitsthrough the New Source Performance Standards (NSPS) under Section 111 of the Clean Air Act. Pursuant to President 912xSource: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Obama’s June 25, 2013 memorandum to U.S. EPA, the Agency re-proposed a Section 111(b) regulation for new units in September 2013that may result in material costs of compliance for CO2 emissions for new fossil-fuel electric generating units, particularly coal-fired units.Under the President’s memorandum, the U.S. EPA is also required to propose a Section 111(d) rule no later than June 1, 2014 to establishCO2 emission regulations for existing stationary sources. Pursuant to the President’s Climate Action Plan, the U.S. EPA re-proposedregulations for the GHG emissions from new fossil fueled power plants on September 20, 2013. The U.S. EPA is also expected to proposeby June 2014 GHG emission regulations for existing stationary sources under Section 111(d) of the Clean Air Act, and to issue finalregulations by June 2015. While the nature and impact of the final regulations is not yet known, to the extent that the rule results in emissionreductions from fossil fuel fired plants, imposing some form of direct or indirect price of carbon in competitive electricity markets, Exelon’soverall low-carbon generation portfolio results would benefit. Exelon supports comprehensive climate change legislation or regulation, including a cap-and-trade program for GHG emissions, whichbalances the need to protect consumers, business and the economy with the urgent need to reduce national GHG emissions. Water Quality. Section 316(b) of the Clean Water Act requires that cooling water intake structures at electric power plants reflect the besttechnology available to minimize adverse environmental impacts, and is implemented through state-level NPDES permit programs. OnMarch 28, 2011, the U.S. EPA issued a proposed rule, and is required under a Settlement Agreement to issue a final rule by November 4,2013; on October 30, 2013 the U.S. EPA invoked the force majeure provision of the Settlement Agreement to extend the final rule deadlineuntil November 20, 2013 due to the early October 2013 federal government shutdown. The U.S. EPA and the plaintiffs have stated that thedeadline will be extended again for a brief period, but have not yet agreed on a date. The proposed rule does not require closed cycle cooling(e.g., cooling towers) as the best technology available, and also provides some flexibility in the use of cost-benefit considerations and site-specific factors. The proposed rule affords the state permitting agency wide discretion to determine the best technology available, which,depending on the site characteristics, could include closed cycle cooling, advanced screen technology at the intake, or retention of the currenttechnology. It is unknown at this time whether the final regulations will require closed-cycle cooling. The economic viability of Generation’s facilitieswithout closed-cycle cooling water systems will be called into question by any requirement to construct cooling towers. Should the final rulenot require the installation of cooling towers, and retain the flexibility afforded the state permitting agencies in applying a cost-benefit test andto consider site-specific factors, the impact of the rule would be minimized even though the costs of compliance could be material toGeneration. Hazardous and Solid Waste. Under proposed U.S. EPA rules issued on June 21, 2010, coal combustion residuals (CCR) would beregulated for the first time under the RCRA. The U.S. EPA is considering several options, including classification of CCR either as ahazardous or non-hazardous waste, under RCRA. Under either option, the U.S. EPA’s intention is the ultimate elimination of surfaceimpoundments as a waste treatment process. For plants affected by the proposed rules, this would result in significant capital expendituresand variable operating and maintenance expenditures to convert to dry handling and disposal systems and installation of new waste watertreatment facilities. Generation’s plants that would be affected by the proposed rules are Keystone and Conemaugh in Pennsylvania, whichhave on-site landfills that meet the requirements of Pennsylvania solid waste regulations for non-hazardous waste disposal. However, untilthe final rule is adopted, the impact on these facilities is unknown. The U.S. EPA has entered into a Consent Decree which requires that afinal rule be issued by December 19, 2014. See Note 22 of the Combined Notes to Consolidated Financial Statements for further detail related to environmental matters, includingthe impact of environmental regulation. 92Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

On March 11, 2011, Japan experienced a 9.0 magnitudeearthquake and ensuing tsunami that seriously damaged the nuclear units at the Fukushima Daiichi Nuclear Power Station, which areoperated by Tokyo Electric Power Co. In July 2011, an NRC Task Force formed in the aftermath of the Fukushima Daiichi events issued a report of its review of the accident,including recommendations for future regulatory action by the NRC to be taken in the near and longer term. The NRC staff and the TaskForce concluded that nuclear reactors in the United States are operating safely and do not present an imminent risk to public health andsafety. The Task Force’s report did not recommend any changes to the existing nuclear licensing process in the United States or changes inthe storage of spent nuclear fuel within the plant’s spent nuclear fuel pools. In 2012, the NRC authorized its staff to issue three immediately effective orders (Tier 1 orders) to commercial reactor licenseesoperating in the United States for compliance no later than December 31, 2016. In addition, in 2012, the NRC staff recommended to theNRC the installation of engineered containment filtered venting systems for boiling-water reactors (BWR) with Mark I and Mark IIcontainment structures. In summary, through the initial and/or subsequent orders and the NRC approved implementation guidance, the Tier1 orders currently: (1) require licensees to provide sufficient onsite portable equipment and resources to maintain or restore coolingcapabilities for the core and spent fuel pool and to maintain containment integrity until offsite equipment is available and have offsiteequipment and resources available to sustain cooling functions indefinitely; (2) provide requirements for vents for BWR’s with Mark I andMark II containments to remain functional during severe accident conditions including the ability to vent the containment following coredamage; and (3) require licensees to install instrumentation to provide a reliable indication of water level in the spent fuel pool. Finally, theNRC has directed the NRC staff to produce a technical evaluation to support rulemaking that considers filtering and performance-basedstrategies as options for BWR’s with Mark I and Mark II containments. The NRC staff must then develop a final rule by March 2017. Additionally, in 2012, the NRC had issued a detailed information request to every operating commercial nuclear power plant in theUnited States. The information requested requires: (1) use of the current NRC guidance to reevaluate current seismic and flood risk hazardsagainst the design basis and provide a plan of actions to address vulnerabilities, including risks exceeding the design basis; (2) performanceof walk downs to ensure the ability to respond to seismic and external flooding events and provide a corrective action plan to the NRC toaddress deficiencies; and (3) assessment of the means to provide power for communications equipment during a severe natural event andidentify staffing required to implement the emergency plan for an event affecting all units with an extended loss of alternating current powerand impeded access to the site. The nuclear industry proposed, and the NRC approved, an augmented approach to the seismic hazardanalysis to accommodate industry wide availability of qualified technical resources needed to perform the required analysis. The NRCapproved this augmented approach. Generation has assessed the impacts of the Tier 1 orders and information requests and will continue monitoring the additionalrecommendations under review by the NRC staff, both from an operational and a financial impact standpoint. A comprehensive review of theNRC Tier 1 orders and information requests, as well as preliminary engineering assumptions and analysis, indicate that the financial impactof compliance for the period from 2014 through 2018 is expected to be between approximately $350 million and $375 million of capital and$50 million of operating expense, as previously anticipated in Generation’s planning projections. As Generation completes the design andinstallation planning for its actions, Generation will update these estimates. Further, Generation estimates incremental costs of $15 to $20million per unit at eleven Mark I and II units for the installation of filtered vents, if ultimately required by the NRC. Generation’s currentassessments are specific to the Tier 1 recommendations as 93Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. the NRC has not taken specific action with respect to the Tier 2 and Tier 3 recommendations. Exelon and Generation are unable to concludeat this time to what extent any actions to comply with the requirements of Tier 2 and Tier 3 will impact their future financial position, resultsof operations, and cash flows. Generation will continue to engage in nuclear industry assessments and actions and stakeholder input. SeeItem 1A. Risk Factors, for further discussion of the risk factors. Financial Reform Legislation. The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) was enacted inJuly 2010. While the Dodd-Frank Act is focused primarily on the regulation and oversight of financial institutions, it also provides for a newregulatory regime for over-the-counter swaps (Swaps), including mandatory clearing, exchange trading, margin requirements, and othertransparency requirements. The Dodd-Frank Act, however, also preserves the ability of end users in the energy industry to hedge their risks.In April 2012, the CFTC issued its rule defining swap dealers and major swap participants. Exelon has determined that it will conduct itscommercial business in a manner that does not require registration as a swap dealer or major swap participant. Notwithstanding, there areadditional rulemakings that have not yet been issued, including the capital and margin rules, which will further define the scope of theregulations and provide clarity as to the impact on the Registrants’ business, as well as to potential new opportunities. Depending on thesefinal rules, the Registrants could be subject to significant new obligations. The proposed regulations addressing collateral and capital requirements and exchange margin cash postings, when final, couldrequire Generation to increase collateral requirements or cash postings in lieu of letters of credit currently issued to collateralize Swaps.Exelon had previously estimated that it could be required to make up to $1 billion of additional collateral postings under its bilateral creditlines. Given the swap dealer and the major swap participant definitions will not apply to Generation, the actual amount of collateral postingsthat will be required may be lower than Exelon’s previous expectations due to the following factors: (a) the majority of Generation’s physicalwholesale portfolio does not meet the final CFTC Swap definition; (b) there will be minimal incremental costs associated with Generation’spositions that are currently cleared and subject to exchange margin; and (c) Generation will not be a swap dealer or major swap participantand proposed capital requirements applicable to these entities will not apply to Generation. The actual level of collateral required will depend on many factors, including but not limited to market conditions, the outcome of finalmargin rules for Swaps, the extent of its trading activity in Swaps, and Generation’s credit ratings. Nonetheless, Generation has adequatecredit facilities and flexibility in its hedging program to meet its anticipated collateral requirements estimated based on conservativeassumptions. In addition, the new regulations will impose new and ongoing compliance and infrastructure costs on Generation, which may amountto several million dollars per year. Exelon and Generation continue to monitor the rulemaking procedures and cannot predict the ultimate outcome that the financialreform legislation will have on their results of operations, cash flows or financial position. ComEd, PECO and BGE could also be subject to various Dodd-Frank Act requirements to the extent they enter into Swap transactions.However, at this time, management of ComEd, PECO and BGE do not expect to be materially affected by this legislation. Energy Infrastructure Modernization Act. Since 2011, ComEd’s distribution rates are established through a performance-based rateformula, pursuant to EIMA. EIMA also provides a structure for substantial capital investment by utilities over a ten-year period to modernizeIllinois’ electric utility infrastructure. Participating utilities are required to file an annual update to the performance-based 94Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. formula rate tariff on or before May 1, with resulting rates effective in January of the following year. This annual formula rate update is basedon prior year actual costs and current year projected capital additions. The update also reconciles any differences between the revenuerequirement(s) in effect for the prior year and actual costs incurred for that year. Throughout each year, ComEd records regulatory assets orregulatory liabilities and corresponding increases or decreases to operating revenues for any differences between the revenue requirement(s)in effect and ComEd’s best estimate of the revenue requirement expected to be approved by the ICC for that year’s reconciliation. Formula Rate Tariff In March 2013, the Illinois legislature passed Senate Bill 9 to clarify the intent of EIMA on the three issues decided in the RehearingOrder: an allowed return on ComEd’s pension asset; the use of year-end rather than average rate base and capital structure in the annualreconciliation; and the use of ComEd’s weighted average cost of capital interest rate rather than a short-term debt rate to apply to the annualreconciliation. On May 22, 2013, Senate Bill 9 became effective after the Illinois legislature overrode the Governor’s veto of that Bill. OnJune 5, 2013, the ICC approved ComEd’s updated distribution formula rate structure to reflect the impacts of Senate Bill 9. In October 2013, the ICC opened an investigation (the Investigation), in response to a complaint filed by the Illinois Attorney General, tochange the formula rate structure by requesting three changes: the elimination of the income tax gross-up on the weighted average cost ofcapital used to calculate interest on the annual reconciliation balance, the netting of associated accumulated deferred income taxes against theannual reconciliation balance in calculating interest, and the use of average rather than year-end rate base for determining any ROE collaradjustment. On November 26, 2013, the ICC issued its final order in the Investigation, rejecting two of the proposed changes but acceptingthe proposed change to eliminate the income tax gross-up on the weighted average cost of capital used to calculate interest on the annualreconciliation balance. The accepted change became effective in January 2014, and is estimated to reduce ComEd’s 2014 revenue byapproximately $8 million. ComEd and intervenors requested rehearing, however all rehearing requests were denied by the ICC. ComEdand intervenors have filed appeals with the Illinois Appellate Court. ComEd cannot predict the results of any such appeals. See 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information. Annual Reconciliation On May 30, 2013, ComEd updated its revenue requirement allowed in the December 2012 Order to reflect the impacts of Senate Bill9, which resulted in a reduction to the current revenue requirement in effect of $14 million. The rates took effect in July 2013. 2013 Filing. On April 29, 2013, ComEd filed its annual distribution formula rate, which was updated on May 30, 2013 to reflect theimpacts of Senate Bill 9. The ICC’s final order, issued on December 19, 2013, increased the revenue requirement by $341 million,reflecting an increase of $160 million for the initial revenue requirement for 2013 and an increase of $181 million for the annualreconciliation for 2012. The rate increase was set using an allowed return on capital of 6.94% (inclusive of an allowed return on commonequity of 8.72%). The rates took effect in January 2014. ComEd requested a rehearing on specific issues, which was denied by the ICC.ComEd and intervenors also filed appeals. ComEd cannot predict the results of any such appeals.

In July 2012, FERC issued an order to Ameren Corporation (Ameren) finding that Ameren had improperlyincluded acquisition premiums/ goodwill in its transmission formula rate, particularly in its capital structure and in the application of AFUDC.FERC also directed Ameren to make 95Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. refunds for the implied increase in rates in prior years. Ameren has filed for rehearing regarding the July 2012 FERC order. ComEd believesthat the FERC order authorizing its transmission formula rate is distinguishable from the circumstances that led to the July 2012 FERCorder in the Ameren case. However, if ComEd were required to exclude acquisition premiums/ goodwill from its transmission formula rate,the impact could be material to ComEd’s results of operations and cash flows. FERC Order No. 1000 Compliance (ComEd, PECO and BGE). In FERC Order No. 1000, the FERC required public utilitytransmission providers to enhance their transmission planning procedures and their cost allocation methods applicable to certain newregional and interregional transmission projects. As part of the changes to the transmission planning procedures, the FERC requiredremoval from all FERC-approved tariffs and agreements a right of first refusal to build certain new transmission facilities. In compliance withthe regional transmission planning requirements of Order No. 1000, PJM as the transmission provider submitted a compliance filing toFERC on October 25, 2012. On the same day, certain of the PJM transmission owners including ComEd, PECO and BGE (collectively, thePJM Transmission Owners) submitted a filing asserting that their contractual rights embodied in the PJM governing documents continue tojustify their right of first refusal to construct new reliability (and related) transmission projects and that the FERC should not be allowed tooverride such rights absent a showing that it is in the public interest to do so under the FERC’s “Mobile-Sierra” standard of review. This is aheightened standard of review which the PJM Transmission Owners argued could not be satisfied based on the facts applicable to them. OnMarch 22, 2013, FERC issued an order on the PJM Compliance Filing and the filing of these PJM Transmission Owners (1) rejecting thearguments of such PJM Transmission Owners that the PJM governing documents were entitled to review under the Mobile-Sierrastandard, (2) accepting most of the PJM filing, removing the right-of-first refusal from the PJM tariffs; and (3) directing PJM to remove certainexceptions that it included in its compliance filing that FERC found did not comply with Order No. 1000. FERC’s order could enable thirdparties to seek to build certain regional transmission projects that had previously been reserved for the PJM Transmission Owners,potentially reducing ComEd’s, PECO’s and BGE’s financial return on new investments in energy transmission facilities. Numerous partiessought rehearing of the FERC’s March 22, 2013 order, including the PJM Transmission Owners who sought rehearing of the FERC’srejection of their Mobile-Sierra and related arguments. The compliance filing was made on July 22, 2013. On January 16, 2014, FERCissued an order stating that PJM’s filing while subject to further orders, is effective as of January 1, 2014. FERC Transmission Complaint. On February 27, 2013, consumer advocates and regulators from the District of Columbia, NewJersey, Delaware and Maryland, and the Delaware Electric Municipal Cooperatives (the parties), filed a complaint at FERC against BGE andthe Pepco Holdings, Inc. companies relating to their respective transmission formula rates. As of December 31, 2013, BGE cannot predictthe likelihood or a reasonable estimate of the amount of a change, if any, in the allowed base return on equity, or a reasonable estimate of therefund period start date. While BGE cannot predict the outcome of this matter, if FERC orders a reduction of BGE’s base return on equity to8.7%, the annual impact would be a reduction in revenues of approximately $10 million. See Note 3—Regulatory Matters of the CombinedNotes to Consolidated Financial Statements for additional information. The Maryland Strategic Infrastructure Development and Enhancement Program. In February 2013, the Maryland GeneralAssembly passed legislation intended to accelerate gas infrastructure replacements in Maryland by establishing a mechanism for gascompanies to promptly recover reasonable and prudent costs of eligible infrastructure replacement projects separate from base rateproceedings. Under the new law, following a proceeding before the MDPSC and with the MDPSC’s approval of the eligible infrastructurereplacement projects along with a corresponding surcharge, BGE could begin charging gas customers a monthly surcharge for infrastructurecosts incurred after June 1, 2013. On August 2, 2013, BGE filed its infrastructure replacement plan and associated surcharge. The newsurcharge rates are expected to take effect in the first quarter of 2014. BGE cannot predict the 96Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The MDPSC held evidentiaryhearings on BGE’s proposed plan and surcharge on November 12, 2013 through November 14, 2013. On January 29, 2014, the MDPSCissued a decision conditionally approving the first five years of BGE’s plan and surcharge. BGE must submit a list detailing specific projectsplanned for 2014 to the MDPSC for approval within 30 days of the decision. Upon approval of the project list by the MDPSC, BGE will beable to implement the surcharge rates on gas customers’ bills. The new surcharges are expected to take effect in the second quarter of2014. In addition, BGE will be subject to an annual independent audit to review plan performance and progress. See Note 3—RegulatoryMatters of the Combined Notes to Consolidated Financial Statements for additional information. Critical Accounting Policies and Estimates The preparation of financial statements in conformity with GAAP requires that management apply accounting policies and makeestimates and assumptions that affect results of operations and the amounts of assets and liabilities reported in the financial statements.Management discusses these policies, estimates and assumptions with its accounting and disclosure governance committee on a regularbasis and provides periodic updates on management decisions to the audit committee of the Exelon board of directors. Management believesthat the accounting policies described below require significant judgment in their application, or estimates and assumptions that areinherently uncertain and that may change in subsequent periods. Additional discussion of the application of these accounting policies can befound 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 $4.9 billion at December 31, 2013. The authoritativeguidance requires that Generation estimate its obligation for the future decommissioning of its nuclear generating plants. To estimate thatliability, Generation uses an internally-developed, probability-weighted, discounted cash flow model which, on a unit-by-unit basis, considersmultiple outcome scenarios. The nuclear decommissioning obligation is adjusted on a regular basis due to the passage of time and revisionsto the key assumptions for the expected timing or estimated amounts of the future undiscounted cash flows required to decommission thenuclear plants, based upon the methodologies and significant estimates and assumptions described as follows: Decommissioning Cost Studies. Generation uses unit-by-unit decommissioning cost studies to provide a marketplace assessmentof the costs and timing of decommissioning activities, which are validated by comparison to current decommissioning projects within itsindustry and other estimates. Decommissioning cost studies are updated, on a rotational basis, for each of Generation’s nuclear units atleast every five years. Cost Escalation Factors. Generation uses cost escalation factors to escalate the decommissioning costs from the decommissioningcost studies discussed above through the assumed decommissioning period for each of the units. Cost escalation studies, updated on anannual basis, are used to determine escalation factors, and are based on inflation indices for labor, equipment and materials, energy, LLRWdisposal and other costs. Probabilistic Cash Flow Models. Generation’s probabilistic cash flow models include the assignment of probabilities to variousscenarios for decommissioning costs, approaches and timing on a unit-by-unit basis. Probabilities assigned to cost levels include anassessment of the likelihood of costs 20% higher (high-cost scenario) or 15% lower (low-cost scenario) than the base cost scenario.Probabilities are assigned to alternative decommissioning approaches which assess the likelihood of performing DECON (a method ofdecommissioning shortly after the cessation of operation in which the equipment, structures, and portions of a facility and site containingradioactive contaminants are removed and safely buried in a LLRW landfill or decontaminated to a level that permits property to be releasedfor 97Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. unrestricted use), Delayed DECON (similar to the DECON scenario but with a delay to allow for spent fuel to be removed from the site priorto onset of decommissioning activities) or SAFSTOR (a method of decommissioning in which the nuclear facility is placed and maintained insuch condition that the nuclear facility can be safely stored and subsequently decontaminated to levels that permit release for unrestricted usegenerally within 60 years after cessation of operations) decommissioning. Probabilities assigned to the timing scenarios incorporate thelikelihood of continued operation through current license lives or through anticipated license renewals. Generation’s probabilistic cash flowmodels also include an assessment of the timing of DOE acceptance of SNF for disposal, which Generation assumed would begin in 2025in 2013 and 2012. The SNF acceptance date was based on management’s estimates of the amount of time required for the DOE to select asite location and develop the necessary infrastructure. For more information regarding the estimated date that DOE will begin accepting SNF,see Note 22 of the Combined Notes to Consolidated Financial Statements. License Renewals. Generation assumes a successful 20-year renewal for each of its nuclear generating station licenses, except forOyster Creek, in determining its nuclear decommissioning ARO. The current NRC license for Oyster Creek expires in 2029. OnDecember 8, 2010, Exelon announced that Generation will permanently cease generation operations at Oyster Creek by December 31,2019. As a result of this decision the expected economic life of Oyster Creek was reduced by 10 years to correspond to Exelon’s current bestestimate as to the timing of ceasing generation operations at the Oyster Creek unit in 2019. Generation has successfully secured 20-yearoperating license renewal extensions for ten of its nuclear units (including the two Salem units co-owned by Generation, but operated byPSEG), and none of Generation’s applications for an operating license extension have been denied. Generation is in various stages of theprocess of pursuing similar extensions on its remaining nine operating nuclear units. Generation’s assumption regarding license extensionfor ARO determination purposes is based in part on the good current physical condition and high performance of these nuclear units; thefavorable status of the ongoing license renewal proceedings with the NRC, and the successful renewals for ten units to date. Generationestimates that the failure to obtain license renewals at any of these nuclear units (assuming all other assumptions remain constant) wouldincrease its ARO on average approximately $210 million per unit as of December 31, 2013. The size of the increase to the ARO for aparticular nuclear unit is dependent upon the current stage in its original license term and its specific decommissioning cost estimates. IfGeneration does not receive license renewal on a particular unit, the increase to the ARO may be mitigated by Generation’s ability to delayultimate decommissioning activities under a SAFSTOR method of decommissioning. Discount Rates. The probability-weighted estimated future cash flows using these various scenarios are discounted using credit-adjusted, risk-free rates (CARFR) applicable to the various businesses in which each of the nuclear units originally operated. The accountingguidance required Generation to establish an ARO at fair value at the time of the initial adoption of the current accounting standard.Subsequent to the initial adoption, the ARO is adjusted for changes to estimated costs, timing of future cash flows and modifications todecommissioning assumptions, as described above. Under the current accounting framework, the ARO is not required or permitted to be re-measured for changes in the CARFR that occurin isolation. This differs from the accounting requirements for other long-dated obligations, such as pension and other post-employmentbenefits that are required to be re-measured as and when corresponding discount rates change. If Generation’s future nominal cash flowsassociated with the ARO were to be discounted at current prevailing CARFRs, the obligation would increase from approximately $4.9 billionto approximately $5.5 billion. The ultimate decommissioning obligation will be funded by the NDTs. The NDTs are recorded on Exelon’s andGeneration’s Consolidated Balance Sheets at December 31, 2013 at fair value of approximately $8.1 billion and have an estimated targetedannual pre-tax return of 5.9 % to 6.7 %. To illustrate the significant impact that changes in the CARFR, when combined with changes in projected amounts and expectedtiming of cash flows, can have on the valuation of the ARO: i) had 98Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Generation used the 2012 CARFRs rather than the 2013 CARFRs in performing its third quarter 2013 ARO update, Generation would havereduced the ARO by approximately $10 million as compared to the actual decrease to the ARO of $140 million; and ii) if the CARFR used inperforming the third quarter 2013 ARO update (which also reflected increases in the amounts and changes to the timing of projected cashflows) was increased or decreased by 100 basis points, the ARO would have decreased by $300 million and increased $40 million,respectively, as compared to the actual decrease of $140 million. ARO Sensitivities. Changes in the assumptions underlying the foregoing items could materially affect the decommissioningobligation. The impact to the ARO of a change in any one of these assumptions is highly dependent on how the other assumptions willchange as well. As an example, Exelon had a historical increase of approximately $670 million in the value of the ARO which was driven byGeneration modifying the assumed timing of the DOE acceptance of SNF for disposal from 2020 to 2025. The modification of the assumedDOE acceptance date affected the calculation of the ARO in isolation as follows; i) the change in the timing of DOE acceptance of SNFincreased the total number of years in which decommissioning activities are estimated to occur, by five years on average, thereby increasingthe total expected nominal cash flows required to decommission the units; ii) the nominal cash flows were subjected to additional escalationas a result of the extension of the decommissioning period increasing the total estimated costs required to decommission the units; and iii)the escalated cash flows were discounted at the then current CARFRs which had dramatically decreased during that time period. The following table illustrates the effects of changing certain ARO assumptions, discussed above, while holding all other assumptionsconstant (dollars in millions): Change in ARO Assumption Increase (Decrease) toARO atDecember 31, 2013 Cost escalation studies Uniform increase in escalation rates of 25 basis points $560 Probabilistic cash flow models Increase the likelihood of the high-cost scenario by 10 percentage points and decrease the likelihood ofthe low-cost scenario by 10 percentage points $190 Increase the likelihood of the DECON scenario by 10 percentage points and decrease the likelihood ofthe SAFSTOR scenario by 10 percentage points $290 Increase the likelihood of operating through current license lives by 10 percentage points and decreasethe likelihood of operating through anticipated license renewals by 10 percentage points $430 Extend the estimated date for DOE acceptance of SNF to 2030 $50 Extend the estimated date for DOE acceptance of SNF to 2030 coupled with an increase in discountrates of 100 basis points $(230) Extend the estimated date for DOE acceptance of SNF to 2030 coupled with a decrease in discountrates of 100 basis points $600 For more information regarding accounting for nuclear decommissioning obligations, see Notes 1 and 15 of the Combined Notes toConsolidated Financial Statements. Goodwill (Exelon and ComEd) As of December 31, 2013, Exelon’s and ComEd’s carrying amount of goodwill was approximately $2.6 billion, relating to theacquisition of ComEd in 2000 as part of the PECO/Unicom Merger. Under the provisions of the authoritative guidance for goodwill, ComEdis required to perform an assessment for possible impairment of its goodwill at least annually or more frequently if an event occurs orcircumstances change that would more likely than not reduce the fair value of the ComEd reporting unit 99Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. below its carrying amount. Under the authoritative guidance, a reporting unit is an operating segment or operating component and is the levelat which goodwill is tested for impairment. Entities assessing goodwill for impairment have the option of first performing a qualitativeassessment to determine whether a quantitative assessment is necessary. In performing a qualitative assessment, entities should assess,among other things, macroeconomic conditions, industry and market considerations, overall financial performance, cost factors, and entity-specific events. If an entity determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than notgreater than the carrying amount, no further testing is required. If an entity bypasses the qualitative assessment or performs the qualitativeassessment, but determines that it is more likely than not that its fair value is less than its carrying amount, a quantitative two-step, fairvalue-based test is performed. The first step compares the fair value of the reporting unit to its carrying amount, including goodwill. If thecarrying amount of the reporting unit exceeds its fair value, the second step is performed. The second step requires an allocation of fair valueto the individual assets and liabilities using purchase price allocation accounting guidance in order to determine the implied fair value ofgoodwill. If the implied fair value of goodwill is less than the carrying amount, an impairment loss is recorded as a reduction to goodwill and acharge to operating expense. Application of the goodwill impairment test requires management judgment, including the identification ofreporting units and determining the fair value of the reporting unit, which management estimates using a weighted combination of adiscounted cash flow analysis and a market multiples analysis. Significant assumptions used in these fair value analyses include discountand growth rates, utility sector market performance and transactions, projected operating and capital cash flows for ComEd’s business andthe fair value of debt. In applying the second step (if needed), management must estimate the fair value of specific assets and liabilities of thereporting unit. Management concluded the remeasurement of the like-kind exchange position and the charge to ComEd’s earnings in the first quarterof 2013 triggered an interim goodwill impairment assessment and, as a result, ComEd tested its goodwill for impairment as of January 31,2013. The first step of the interim impairment assessment comparing the estimated fair value of ComEd to its carrying value, includinggoodwill, indicated no impairment of goodwill; therefore, the second step was not required. ComEd performed a quantitative assessment as of November 1, 2013, for its 2013 annual goodwill impairment assessment. The firststep of the interim impairment assessment comparing the estimated fair value of ComEd to its carrying value, including goodwill, indicatedno impairment of goodwill; therefore, the second step was not required. While neither the interim nor the annual assessments indicated an impairment of ComEd’s goodwill, certain assumptions used toestimate the fair value of ComEd are highly sensitive to changes. Adverse regulatory actions, such as early termination of EIMA, or changesin significant assumptions, including discount and growth rates, utility sector market performance and transactions, projected operating andcapital cash flows from ComEd’s business, and the fair value of debt, could potentially result in a future impairment of ComEd’s goodwill,which could be material. Based on the results of the annual goodwill test performed as of November 1, 2013, the estimated fair value ofComEd would have needed to decrease by more than 10% for ComEd to fail the first step of the impairment test. See Note 1—SignificantAccounting Policies, Note 10—Intangible Assets and Note 14—Income Taxes of the Combined Notes to Consolidated Financial Statementsfor additional information. Purchase Accounting (Exelon and Generation) In accordance with the authoritative accounting guidance, the purchase price of an acquired business is generally allocated to the assetsacquired and liabilities assumed at their estimated fair values on the date of acquisition. Any unallocated purchase price amount is recognizedas goodwill on the balance sheet if it exceeds the estimated fair value and as a bargain purchase gain on the income statement if it is belowthe estimated fair value. Determining the fair value of assets acquired and 100Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. liabilities assumed requires management’s judgment, the utilization of independent valuation experts and involves the use of significantestimates and assumptions with respect to the timing and amounts of future cash inflows and outflows, discount rates, market prices andasset lives, among other items. The judgments made in the determination of the estimated fair value assigned to the assets acquired andliabilities assumed, as well as the estimated useful life of each asset and the duration of each liability, can materially impact the financialstatements in periods after acquisition, such as through depreciation and amortization expense. See Note 4—Merger and Acquisitions of theCombined Notes to Consolidated Financial Statements for additional information. Unamortized Energy Assets and Liabilities (Exelon and Generation) Unamortized energy contract assets and liabilities represent the remaining unamortized balances of non-derivative energy contracts thatGeneration has acquired. The initial amount recorded represents the fair value of the contract at the time of acquisition, and the balance isamortized over the life of the contract in relation to the present value of the underlying cash flows. Amortization expense and income arerecorded through purchased power and fuel expense or operating revenues. Refer to Note 4—Mergers and Acquisitions and Note 10—Intangible Assets for further discussion. Impairment of Long-lived Assets (Exelon, Generation, ComEd, PECO and BGE) Exelon, Generation, ComEd, PECO and BGE regularly monitor and evaluate their long-lived assets and asset groups, excludinggoodwill, for impairment when circumstances indicate the carrying value of those assets may not be recoverable. Conditions that could havean adverse impact on the cash flows and fair value of the long-lived assets are deteriorating business climate, including current energy pricesand market conditions, condition of the asset, specific regulatory disallowance, or plans to dispose of a long-lived asset significantly before theend of its useful life, among others. The review of long-lived assets and asset groups for impairment requires significant assumptions about operating strategies andestimates 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, costs of fuel and the expectedoperations of assets. A variation in the assumptions used could lead to a different conclusion regarding the recoverability of an asset or assetgroup and, thus, could have a significant effect on the consolidated financial statements. An impairment evaluation is based on anundiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets or asset groups are largely independent ofother groups of assets and liabilities. For the generation business, the lowest level of independent cash flows is determined by evaluation ofseveral factors, including the geographic dispatch of the generation units and the hedging strategies related to those units and associatedintangible contract assets recorded on the balance sheet. The cash flows from the generation units are generally evaluated at a regionalportfolio level with cash flows generated from Generation’s customer supply and risk management activities, including cash flows fromcontracts that are accounted for as intangible contract assets and liabilities recorded on the balance sheet. In certain cases generation assetsmay be evaluated on an individual basis where those assets are contracted on a long-term basis with a third party and operations areindependent of other generation assets (typically contracted renewables). Impairment may occur when the carrying value of the asset or asset group exceeds the future undiscounted cash flows. When theundiscounted cash flow analysis indicates a long-lived asset or asset group is not recoverable, the amount of the impairment loss isdetermined by measuring the excess of the carrying amount of the long-lived asset or asset group over its fair value. The fair value of thelong-lived asset or asset group is dependent upon a market participant’s view of the exit price of the assets. This includes significantassumptions of the estimated future cash flows generated by the assets and market discount rates. Events and circumstances frequently donot occur as expected and 101Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. there will usually be differences between prospective financial information and actual results, and those differences may be material.Accordingly, to the extent that any of the information used in the fair value analysis requires adjustment, the resulting fair market valuewould be different. As such, the determination of fair value is driven by both internal assumptions that include significant unobservableinputs (Level 3) such as revenue and generation forecasts, projected capital, and maintenance expenditures and discount rates, as well asinformation from various public, financial and industry sources. An impairment determination would require the affected Registrant to reduceeither the long-lived asset or asset group, including any intangible contract assets and liabilities, and current period earnings by the amountof the impairment. Generation evaluates unproved gas producing properties at least annually to determine if they are impaired. Impairment for unprovedgas property occurs if there are no firm plans to continue drilling, lease expiration is at risk, or historical experience indicates a decline incarrying value below fair value. Exelon holds investments in coal-fired plants in Georgia and Texas subject to long-term leases. The investments are accounted for asdirect financing lease investments. The investments represent the estimated residual values of the leased assets at the end of the respectivelease terms. On an annual basis, Exelon reviews the estimated residual values of its direct financing lease investments and records animpairment charge if the review indicates an other than temporary decline in the fair value of the residual values below their carrying values.Exelon estimates the fair value of the residual values of its direct financing lease investments using a discounted cash flow analysis, whichtakes into consideration the expected revenues to be generated and costs to be incurred to operate the plants over their remaining useful livessubsequent to the lease end dates. Generation also evaluates its equity method investments to determine whether or not they are impaired based on whether theinvestment has experienced a decline in value that is not temporary in nature. Additionally, if one of Generation’s equity method investmentsrecognize an impairment, Generation would record its proportionate share of that impairment loss through its equity earnings (losses) ofunconsolidated affiliates. Generation would also evaluate the investment for a decline in value at that time that is not temporary in nature. See Note 8 of the Combined Notes to Consolidated Financial Statements for a discussion of asset impairment evaluations made byExelon. Depreciable Lives of Property, Plant and Equipment (Exelon, Generation, ComEd, PECO and BGE) The Registrants have significant investments in electric generation assets and electric and natural gas transmission and distributionassets. Depreciation of these assets is generally provided over their estimated service lives on a straight-line basis using the compositemethod. The estimation of service lives requires management judgment regarding the period of time that the assets will be in use. Ascircumstances warrant, the estimated service lives are reviewed to determine if any changes are needed. Depreciation rates incorporateassumptions on interim retirements based on actual historical retirement experience. To the extent interim retirement patterns change, thiscould have a significant impact on the amount of depreciation expense recorded in the income statement. Changes to depreciation estimatesresulting from a change in the estimated end of service lives could have a significant impact on the amount of depreciation expense recordedin the income statement. See Note 1 of the Combined Notes to Consolidated Financial Statements for information regarding depreciation andestimated service lives of the property, plant and equipment of the Registrants. The estimated service lives of the nuclear generating facilities are based on the estimated useful lives of the stations, which assume a20-year license renewal extension of the operating licenses for all of Generation’s operating nuclear generating stations except for OysterCreek. While Generation has 102Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. received license renewals for certain facilities, and has applied for or expects to apply for and obtain approval of license renewals for theremaining facilities, circumstances may arise that would prevent Generation from obtaining additional license renewals. Generation alsoevaluates annually the estimated service lives of its generating facilities based on feasibility assessments as well as economic and capitalrequirements. The estimated service lives of hydroelectric facilities are based on the remaining useful lives of the stations, which assume alicense renewal extension of the Conowingo and Muddy Run operating licenses. A change in depreciation estimates resulting fromGeneration’s extension or reduction of the estimated service lives could have a significant effect on Generation’s results of operations.Generation completed a depreciation rate study during the first quarter of 2010, which resulted in the implementation of new depreciationrates effective January 1, 2010. Constellation completed a depreciation rate study during the fourth quarter of 2010, which resulted in theimplementation of new depreciation rates effective during the fourth quarter of 2010. ComEd is required to file a depreciation rate study at least every five years with the ICC. ComEd completed a depreciation study in2014 and filed the updated depreciation rates with both FERC and the ICC in January 2014. This is expected to result in the implementationof new depreciation rates effective first quarter 2014. PECO is required to file a depreciation rate study at least every five years with the PAPUC. In April 2010, PECO filed a depreciation ratestudy with the PAPUC for both its electric and gas assets, which resulted in the implementation of new depreciation rates effectiveJanuary 1, 2010 for electric transmission assets and January 1, 2011 for electric distribution and gas assets. The MDPSC does not mandate the frequency or timing of BGE’s depreciation studies. In December 2006, BGE filed reviseddepreciation rates with the MDPSC for both its electric distribution and gas assets. Revisions to depreciation rates from this filing werefinalized July 1, 2010. Defined Benefit Pension and Other Postretirement Benefits (Exelon, Generation, ComEd, PECO and BGE) Exelon sponsors defined benefit pension plans and other postretirement benefit plans for substantially all Generation, ComEd, PECO,BGE and BSC employees. See Note 16—Retirement Benefits of the Combined Notes to Consolidated Financial Statements for additionalinformation regarding the accounting for the defined benefit pension plans and other postretirement benefit plans. The measurement of the plan obligations and costs of providing benefits under Exelon’s defined benefit pension and otherpostretirement benefit plans involves various factors, including the development of valuation assumptions and accounting policy elections.When developing the required assumptions, Exelon considers historical information as well as future expectations. The measurement ofbenefit obligations and costs is affected by several assumptions including the discount rate applied to benefit obligations, the long-termexpected rate of return on plan assets, the anticipated rate of increase of health care costs, Exelon’s expected level of contributions to theplans, the incidence of participant mortality, the expected remaining service period of plan participants, the level of compensation and rate ofcompensation 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. The impact ofassumption changes or experience different from that assumed on pension and other postretirement benefit obligations is recognized overtime rather than immediately recognized in the income statement. Gains or losses in excess of the greater of ten percent of the projectedbenefit obligation or the MRV of plan assets are amortized over the expected average remaining service period of plan participants. Pensionand other postretirement benefit costs attributed to the operating companies are labor costs and are ultimately allocated to projects within theoperating companies, some of which are capitalized. 103Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Pension and other postretirement benefit plan assets include equity securities, including U.S. and international securities, and fixedincome securities, as well as certain alternative investment classes such as real estate, private equity and hedge funds. See Note 16—Retirement Benefits of the Combined Notes to Consolidated Financial Statements for information on fair value measurements of pensionand other postretirement plan assets, including valuation techniques and classification under the fair value hierarchy in accordance withauthoritative guidance. Expected Rate of Return on Plan Assets. The long-term expected rate of return on plan assets assumption used in calculatingpension costs was 7.50%, 7.50%, and 8.00% for 2013, 2012 and 2011, respectively. The weighted average expected return on assetsassumption used in calculating other postretirement benefit costs was 6.45%, 6.68%, and 7.08% in 2013, 2012 and 2011, respectively. Thepension trust activity is non-taxable, while other postretirement benefit trust activity is partially taxable. The current year EROA is based onasset allocations from the prior year end. In 2010, Exelon began implementation of a liability-driven investment strategy in order to reduce thevolatility of its pension assets relative to its pension liabilities. As a result of this modification, over time, Exelon determined that it willdecrease equity investments and increase investments in fixed income securities and alternative investments in order to achieve a balancedportfolio of liability hedging and return-generating assets. See Note 16—Retirement Benefits of the Combined Notes to ConsolidatedFinancial Statements for additional information regarding Exelon’s asset allocations. Exelon used an EROA of 7.00% and 6.59% to estimateits 2014 pension and other postretirement benefit costs, respectively. Exelon calculates the expected return on pension and other postretirement benefit plan assets by multiplying the EROA by the MRV ofplan 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 calculatedvalue that recognizes changes in fair value in a systematic and rational manner over not more than five years. For the majority of pensionplan assets, Exelon uses a calculated value that adjusts for 20% of the difference between fair value and expected MRV of plan assets. Use ofthis 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. Actual asset returns have an impact on the costs reported for the Exelon-sponsored pension and other postretirement benefit plans. Theactual asset returns across the Registrants’ pension and other postretirement benefit plans for the year ended December 31, 2013 were6.73% and 11.41%, respectively, compared to an expected long-term return assumption of 7.50% and 6.45%, respectively. Discount Rate. The discount rates used to determine the pension and other postretirement benefit obligations were 4.80% and4.90%, respectively, at December 31, 2013. The discount rates at December 31, 2013 represent weighted-average rates for both pension andother postretirement benefit plans. At December 31, 2013 and 2012, the discount rates were determined by developing a spot rate curvebased on the yield to maturity of a universe of high-quality non-callable (or callable with make whole provisions) bonds with similarmaturities to the related pension and other postretirement benefit obligations. The spot rates are used to discount the estimated distributionsunder the pension and other postretirement benefit plans. The discount rate is the single level rate that produces the same result as the spotrate curve. Exelon utilizes an analytical tool developed by its actuaries to determine the discount rates. The discount rate assumptions used to determine the obligation at year end are used to determine the cost for the following year. Exelonwill use discount rates of 4.80% and 4.90% to estimate its 2014 pension and other postretirement benefit costs, respectively. Health Care Reform Legislation. In March 2010, the Health Care Reform Acts were signed into law, which contain a number ofprovisions that impact retiree health care plans provided by employers. 104Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. One such provision reduces the deductibility, for Federal income tax purposes, of retiree health care costs to the extent an employer’spostretirement health care plan receives Federal subsidies that provide retiree prescription drug benefits at least equivalent to those offered byMedicare. Although this change did not take effect immediately, the Registrants were required to recognize the full accounting impact in theirfinancial statements in the period in which the legislation was enacted. Additionally, as a result of this deductibility change for employers andother Health Care Reform provisions that impact the federal prescription drug subsidy options provided to employers, Exelon changed themanner in which it will receive prescription drug subsidies beginning in 2013. The Health Care Reform Acts include a provision that imposes an excise tax on certain high-cost plans beginning in 2018, wherebypremiums paid over a prescribed threshold will be taxed at a 40% rate. Although the excise tax does not go into effect until 2018, accountingguidance requires Exelon to incorporate the estimated impact of the excise tax in its annual actuarial valuation. The application of thelegislation is still unclear and Exelon continues to monitor the Department of Labor and IRS for additional guidance. Effective in 2002,Constellation amended its other postretirement benefit plans for all subsidiaries other than Nine Mile Point by capping retiree medicalcoverage for future retirees who were under the age of 55 on January 1, 2002 at 2002 levels. Therefore, the excise tax is not expected to havea material impact on the legacy Constellation other postretirement benefit plans. However, certain key assumptions are required to estimatethe impact of the excise tax on the other postretirement obligation for legacy Exelon plans, including projected inflation rates (based on theCPI) and whether pre- and post-65 retiree populations can be aggregated in determining the premium values of health care benefits. Exelonreflected its best estimate of the expected impact in its annual actuarial valuation. Health Care Cost Trend Rate. Assumed health care cost trend rates have a significant effect on the costs reported for Exelon’s otherpostretirement benefit plans. Accounting guidance requires that annual health care cost estimates be developed using past and present healthcare cost trends (both for Exelon and across the broader economy), as well as expectations of health care cost escalation, changes in healthcare utilization and delivery patterns, technological advances and changes in the health status of plan participants. Therefore, the trend rateassumption is subject to significant uncertainty, particularly when considering potential impacts of the 2010 Health Care Reform Acts. Exelonassumed an initial health care cost trend rate of 6.50% for 2013, decreasing to an ultimate health care cost trend rate of 5.00% in 2017. Sensitivity to Changes in Key Assumptions. The following tables illustrate the effects of changing certain of the actuarialassumptions discussed above, while holding all other assumptions constant (dollars in millions): Actuarial Assumption Change inAssumption Pension Other PostretirementBenefits Total Change in 2013 cost: Discount rate 0.5% $(63) $(34) $(97) (0.5%) 68 48 116 EROA 0.5% (68) (10) (78) (0.5%) 68 10 78 Health care cost trend rate 1.00% N/A 90 90 (1.00%) N/A (62) (62) Change in benefit obligation atDecember 31, 2013: Discount rate 0.5% (904) (297) (1,201) (0.5%) 965 318 1,283 Health care cost trend rate 1.00% N/A 858 858 (1.00%) N/A (607) (607) 105(a)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. (a)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 implemented aliability-driven investment strategy for a portion of its pension asset portfolio in 2010. The sensitivities shown above do not reflect the offsetting impact that changes indiscount rates may have on pension asset returns. Average Remaining Service Period. For pension benefits, Exelon amortizes its unrecognized prior service costs and certainactuarial gains and losses, as applicable, based on participants’ average remaining service periods. The average remaining service period ofdefined benefit pension plan participants was 11.8 years, 11.9 years, and 12.1 years for the years ended December 31, 2013, 2012 and 2011,respectively. For other postretirement benefits, Exelon amortizes its unrecognized prior service costs over participants’ average remaining serviceperiod to benefit eligibility age and amortizes its transition obligations and certain actuarial gains and losses over participants’ averageremaining service period to expected retirement. The average remaining service period of postretirement benefit plan participants related tobenefit eligibility age was 8.7 years, 8.9 years and 6.6 years for the years ended December 31, 2013, 2012 and 2011, respectively. Theaverage remaining service period of postretirement benefit plan participants related to expected retirement was 9.8 years, 10.1 years and 8.7years for the years ended December 31, 2013, 2012 and 2011, respectively. Regulatory Accounting (Exelon, ComEd, PECO and BGE) Exelon, ComEd, PECO and BGE account for their regulated electric and gas operations in accordance with the authoritative guidancefor accounting for certain types of regulations, which requires Exelon, ComEd, PECO and BGE to reflect the effects of cost-based rateregulation in their financial statements. This guidance is applicable to 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 orproducts; and (3) a reasonable expectation that rates are set at levels that will recover the entities costs from customers. Regulatory assetsrepresent incurred costs that have been deferred because of their probable future recovery from customers through regulated rates.Regulatory liabilities represent (1) the excess recovery of costs or accrued credits that have been deferred because it is probable such amountswill be returned to customers through future regulated rates; or (2) billings in advance of expenditures for approved regulatory programs. As ofDecember 31, 2013, Exelon, ComEd, PECO and BGE have concluded that the operations of ComEd, PECO and BGE meet the criteria toapply the authoritative guidance. If it is concluded in a future period that a separable portion of those operations no longer meets the criteria ofthis guidance, Exelon, ComEd, PECO and BGE would be required to eliminate any associated regulatory assets and liabilities and theimpact would be recognized in the Consolidated Statements of Operations and could be material. See Note 3 of the Combined Notes toConsolidated Financial Statements for additional information regarding regulatory matters, including the regulatory assets and liabilitiestables of Exelon, ComEd, PECO and BGE. For each regulatory jurisdiction in which they conduct business, Exelon, ComEd, PECO and BGE assess whether the regulatoryassets and liabilities continue to meet the criteria for probable future recovery or settlement at each balance sheet date and when regulatoryevents occur. This assessment includes consideration of recent rate orders, historical regulatory treatment for similar costs in ComEd’s,PECO’s and BGE’s jurisdictions, and factors such as changes in applicable regulatory and political environments. Furthermore, Exelon,ComEd, PECO and BGE make other judgments related to the financial statement impact of their regulatory environments, such as thetypes of adjustments to rate base that will be acceptable to regulatory bodies, if any, to which costs will be recoverable through rates.

Additionally, estimates are made in accordance with the authoritative guidance for contingencies as to theamount of revenues billed under certain regulatory orders that may ultimately be refunded to customers upon finalization of applicableregulatory or judicial processes. These assessments are based, to the extent possible, on past relevant experience with regulatory bodies inComEd’s, PECO’s and BGE’s jurisdictions, known circumstances specific to a particular matter and hearings held with the applicableregulatory body. If the assessments and estimates made by Exelon, ComEd, PECO and BGE are ultimately different than actual regulatoryoutcomes, the impact on their results of operations, financial position, and cash flows could be material. The Registrants treat the impacts of a final rate order received after the balance sheet date but prior to the issuance of the financialstatements as a non-recognized subsequent event, as the receipt of a final rate order is a separate and distinct event that has future impactson the parties affected by the order. Accounting for Derivative Instruments (Exelon, Generation, ComEd, PECO and BGE) The Registrants utilize derivative instruments to manage their exposure to fluctuations in interest rates, changes in interest ratesrelated to planned future debt issuances and changes in the fair value of outstanding debt. Generation uses a variety of derivative and non-derivative instruments to manage the commodity price risk of its electric generation facilities, including power sales, fuel and energypurchases and other energy-related products marketed and purchased. Additionally, Generation enters into energy-related derivatives forproprietary trading purposes. ComEd has entered into contracts to procure energy, capacity and ancillary services. In addition, ComEd had afinancial swap contract with Generation that expired May 31, 2013 and currently holds floating-to-fixed energy swaps with several unaffiliatedsuppliers that extend into 2032. PECO and BGE have entered into derivative natural gas contracts to hedge their long-term price risk in thenatural gas market. PECO has also entered into derivative contracts to procure electric supply through a competitive RFP process as outlinedin its PAPUC-approved DSP Program. BGE has also entered into derivative contracts to procure electric supply through a competitive auctionprocess as outlined in its MDPSC-approved SOS Program. ComEd, PECO and BGE do not enter into derivatives for proprietary tradingpurposes. The Registrants’ derivative activities are in accordance with Exelon’s Risk Management Policy (RMP). See Note 12 of theCombined Notes to Consolidated Financial Statements for additional information regarding the Registrants’ derivative instruments. The Registrants account for derivative financial instruments under the applicable authoritative guidance. Determining whether or not acontract qualifies as a derivative under this guidance requires that management exercise significant judgment, including assessing themarket liquidity as well as determining whether a contract has one or more underlyings and one or more notional amounts. Further,interpretive guidance related to the authoritative literature continues to evolve, including how it applies to energy and energy-related products.Changes in management’s assessment of contracts and the liquidity of their markets, and changes in authoritative guidance related toderivatives, could result in previously excluded contracts being subject to the provisions of the authoritative derivative guidance. Generationhas determined that contracts to purchase uranium, contracts to purchase and sell capacity in certain ISO’s, certain emission products andRECs do not meet the definition of a derivative under the current authoritative guidance since they do not provide for net settlement andneither the uranium, certain capacity, emission nor the REC markets are sufficiently liquid to conclude that physical forward contracts arereadily convertible to cash. If these markets do become sufficiently liquid in the future and Generation would be required to account for thesecontracts as derivative instruments, the fair value of these contracts would be accounted for consistent with Generation’s other derivativeinstruments. In this case, if market prices differ from the underlying prices of the contracts, Generation would be required to record mark-to-market gains or losses, which may have a significant impact to Exelon’s and Generation’s financial positions and results of operations. 107Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Under current authoritative guidance, all derivatives are recognized on the balance sheet at their fair value, except for certain derivativesthat qualify for, and are elected under, the normal purchases and normal sales exception. Further, derivatives that qualify and are designatedfor hedge accounting are classified as fair value or cash flow hedges. For fair value hedges, changes in fair values for both the derivative andthe underlying hedged exposure are recognized in earnings each period. For cash flow hedges, the portion of the derivative gain or loss that iseffective in offsetting the change in the hedged cash flows of the underlying exposure is deferred in accumulated OCI and later reclassifiedinto earnings when the underlying transaction occurs. Gains and losses from the ineffective portion of any hedge are recognized in earningsimmediately. For commodity transactions, effective with the date of merger with Constellation, Generation no longer utilizes the electionprovided for by the cash flow hedge designation and de-designated all of its existing cash flow hedges prior to the merger. Because theunderlying forecasted transactions remain probable, the fair value of the effective portion of these cash flow hedges was frozen inaccumulated OCI and will be reclassified to results of operations when the forecasted purchase or sale of the energy commodity occurs, orbecomes probable of not occurring. None of Constellation’s designated cash flow hedges for commodity transactions prior to the merger werere-designated as cash flow hedges. The effect of this decision is that all economic hedges for commodities are recorded at fair value throughearnings for the combined company. In addition, for energy-related derivatives entered into for proprietary trading purposes, changes in thefair value of the derivatives are recognized in earnings each period. For economic hedges that are not designated for hedge accounting forComEd, PECO and BGE, changes in the fair value each period are recorded as a regulatory asset or liability. Normal Purchases and Normal Sales Exception. As part of Generation’s energy marketing business, Generation enters intocontracts to buy and sell energy to meet the requirements of its customers. These contracts include short-term and long-term commitmentsto purchase and sell energy and energy-related products in the retail and wholesale markets with the intent and ability to deliver or takedelivery. While some of these contracts are considered derivative financial instruments under the authoritative guidance, certain of thesequalifying transactions have been designated as normal purchases and normal sales and 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 normal purchases and normal sales exceptionrequires that management exercise judgment on whether the contract will physically deliver and requires that management ensurecompliance with all of the associated qualification and documentation requirements. Revenues and expenses on contracts that qualify asnormal purchases and normal sales are recognized when the underlying physical transaction is completed. Contracts which qualify for thenormal purchases and normal sales exception are those for which physical delivery is probable, quantities are expected to be used or sold inthe normal course of business over a reasonable period of time and is not financially settled on a net basis. The contracts that ComEd hasentered into with suppliers as part of ComEd’s energy procurement process, PECO’s full requirement contracts and block contracts underthe PAPUC-approved DSP program, most of PECO’s natural gas supply agreements and all of BGE’s full requirement contracts and naturalgas supply agreements that are derivatives qualify for the normal purchases and normal sales exception. Commodity Contracts. Identification of a commodity contract as an economic hedge requires Generation to determine that thecontract is in accordance with the RMP. Generation reassesses its economic hedges on a regular basis to determine if they continue to bewithin the guidelines of the RMP. As a part of accounting for derivatives, the Registrants make estimates and assumptions concerning future commodity prices, loadrequirements, interest rates, the timing of future transactions and their probable cash flows, the fair value of contracts and the expectedchanges in the fair value in deciding whether or not to enter into derivative transactions, and in determining the initial accounting treatmentfor derivative transactions. In accordance with the authoritative guidance for fair value measurements, the Registrants categorize thesederivatives under a fair value hierarchy that prioritizes 108Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. 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 categorized in Level 1 in thefair value hierarchy. Certain derivatives’ pricing is verified using indicative price quotations available through brokers or over-the-counter, on-line exchanges are categorized in Level 2. These price quotations reflect the average of the bid-ask mid-point prices and are obtained fromsources that the Registrants believe provide the most liquid market for the commodity. The price quotations are reviewed and corroborated toensure the prices are observable and representative of an orderly transaction between market participants. This includes consideration ofactual transaction volumes, market delivery points, bid-ask spreads and contract duration. The Registrant’s derivatives are tradedpredominately at liquid trading points. The remaining derivative contracts are valued using the Black model, an industry standard optionvaluation model. The Black model takes into account inputs such as contract terms, including maturity, and market parameters, andassumptions of the future prices of energy, interest rates, volatility, credit worthiness and credit spread. For derivatives that trade in liquidmarkets, such as generic forwards, swaps and options, the model inputs are generally observable. Such instruments are categorized inLevel 2. For derivatives that trade in less liquid markets with limited pricing information, the model inputs generally would include bothobservable and unobservable inputs. In instances where observable data is unavailable, consideration is given to the assumptions thatmarket participants would use in valuing the asset or liability. This includes assumptions about market risks such as liquidity, volatility andcontract duration. Such instruments are categorized in Level 3 as the model inputs generally are not observable. The Registrants considernonperformance risk, including credit risk in the valuation of derivative contracts categorized in Level 1, 2 and 3, including both historical andcurrent market data in its assessment of nonperformance risk, including credit risk. The impacts of credit and nonperformance risk to datehave generally not been material to the financial statements. Interest Rate and Foreign Exchange Derivative Instruments. The Registrants may utilize fixed-to-floating interest rate swaps,which are typically designated as fair value hedges, as a means to achieve the targeted level of variable-rate debt as a percent of total debt.Additionally, the Registrants may use forward-starting interest rate swaps and treasury rate locks to lock in interest-rate levels in anticipationof future financings and floating to fixed swaps for project financing. In addition, Generation enters into interest rate derivative contracts toeconomically hedge risk associated with the interest rate component of commodity positions. The characterization of the interest ratederivative contracts between the economic hedge and proprietary trading activity is driven by the corresponding characterization of theunderlying commodity position that gives rise to the interest rate exposure. Generation does not utilize interest rate derivatives with theobjective of benefiting from shifts or change in market interest rates. To manage foreign exchange rate exposure associated with internationalenergy purchases in currencies other than U.S. dollars, Generation utilizes foreign currency derivatives, which are typically designated aseconomic hedges. The fair value of the agreements is calculated by discounting the future net cash flows to the present value based on theterms and conditions of the agreements and the forward interest rate and foreign exchange curves. As these inputs are based on observabledata and valuations of similar instruments, the interest rate and foreign exchange derivatives are primarily categorized in Level 2 in the fairvalue hierarchy. Certain exchange based interest rate derivatives that are valued using unadjusted quoted prices in active markets arecategorized in Level 1 in the fair value hierarchy. See ITEM 7A.

Taxation (Exelon, Generation, ComEd, PECO and BGE) Significant management judgment is required in determining the Registrants’ provisions for income taxes, primarily due to theuncertainty related to tax positions taken, as well as deferred tax assets and 109Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. liabilities and valuation allowances. In accordance with applicable authoritative guidance, the Registrants account for uncertain income taxpositions using a benefit recognition model with a two-step approach including a more-likely-than-not recognition threshold and ameasurement approach based on 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 taxpositions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold.Management evaluates each position based solely on the technical merits and facts and circumstances of the position, assuming the positionwill be examined by a taxing authority having full knowledge of all relevant information. Significant judgment is required to determinewhether the recognition threshold has been met and, if so, the appropriate amount of unrecognized tax benefits to be recorded in theRegistrants’ consolidated financial statements. The Registrants evaluate quarterly the probability of realizing deferred tax assets by reviewing a forecast of future taxable income andtheir intent and ability to implement tax planning strategies, if necessary, to realize deferred tax assets. The Registrants also assess theirability to utilize tax attributes, including those in the form of carryforwards, for which the benefits have already been reflected in the financialstatements. The Registrants record valuation allowances for deferred tax assets when the Registrants conclude it is more-likely-than-notsuch 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 changes in income taxlaws, the Registrants’ forecasted financial condition and results of operations, failure to successfully implement tax planning strategies, aswell as results of audits and examinations of filed tax returns by taxing authorities. While the Registrants believe the resulting tax balancesas of December 31, 2013 and 2012 are appropriately accounted for in accordance with the applicable authoritative guidance, the ultimateoutcome of tax matters could result in favorable or unfavorable adjustments to their consolidated financial statements and such adjustmentscould be material. See Note 14 of the Combined Notes to Consolidated Financial Statements for additional information regarding taxes. Accounting for Loss Contingencies (Exelon, Generation, ComEd, PECO and BGE) In the preparation of their financial statements, the Registrants make judgments regarding the future outcome of contingent events andrecord liabilities for loss contingencies that are probable and can be reasonably estimated based upon available information. The amountsrecorded may differ from the actual expense incurred when the uncertainty is resolved. The estimates that the Registrants make inaccounting for loss contingencies and the actual results that they record upon the ultimate resolution of these uncertainties could have asignificant effect on their consolidated financial statements. Environmental Costs. Environmental investigation and remediation liabilities are based upon estimates with respect to the number ofsites 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 beshared with other parties, the timing of the remediation work, changes in technology, regulations and the requirements of local governmentalauthorities. Periodic studies are conducted at ComEd, PECO and BGE to determine future remediation requirements and estimates areadjusted accordingly. In addition, periodic reviews are performed at Generation to assess the adequacy of its environmental reserves. Thesematters, if resolved in a manner different from the estimate, could have a significant effect on the Registrants’ results of operations, financialposition and cash flows. See Note 22 of the Combined Notes to Consolidated Financial Statements for further 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 110Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. within policy deductibles or exceed the amount of insurance maintained. The Registrants have reserves for both open claims asserted and anestimate of claims incurred but not reported (IBNR). The IBNR reserve is estimated based on actuarial assumptions and analysis and isupdated annually. Future events, such as the number of new claims to be filed each year, the average cost of disposing of claims, as well asthe numerous uncertainties surrounding litigation and possible state and national legislative measures could cause the actual costs to behigher or lower than estimated. Accordingly, these claims, if resolved in a manner different from the estimate, could have a material effect onthe Registrants’ results of operations, financial position and cash flows. Revenue Recognition (Exelon, Generation, ComEd, PECO and BGE) Sources of Revenue and Selection of Accounting Treatment. The Registrants earn revenues from various business activitiesincluding: the sale of energy and energy-related products, such as natural gas, capacity, and other commodities in non-regulated markets(wholesale and retail); the sale and delivery of electricity and natural gas in regulated markets; and the provision of other energy-related non-regulated products and services. The appropriate accounting treatment for revenue recognition is based on the nature of the underlying transaction and applicableaccounting standards. The Registrants primarily use accrual and mark-to-market accounting as discussed in more detail below. Accrual Accounting. Under accrual accounting, the Registrants record revenues in the period when services are rendered or energyis delivered to customers. The Registrants generally use accrual accounting to recognize revenues for sales of electricity, natural gas, andother commodities as part of their physical delivery activities. The Registrants enter into these sales transactions using a variety ofinstruments, including non-derivative agreements, derivatives that qualify for and are designated as normal purchases and normal sales(NPNS) of commodities that will be physically delivered, sales to utility customers under regulated service tariffs, and spot-market sales,including settlements with independent system operators. Mark-to-Market Accounting. The Registrants record revenues using the mark-to-market method of accounting for transactions thatmeet the definition of a derivative for which they are not permitted, or have not elected, the NPNS exception. These mark-to-markettransactions primarily relate to risk management activities and economic hedges of other accrual activities. Mark-to-market revenues include:inception gains or losses on new transactions where the fair value is observable and realized; and unrealized gains and losses from changesin the fair value of open contracts. Use of Estimates. Estimates are based upon actual costs incurred and investments in rate base for the period and the rates of returnon common equity and associated regulatory capital structure allowed under the applicable tariff. The estimated reconciliations can be affectedby, among other things, variances in costs incurred and investments made and actions by regulators or courts. Unbilled Revenues. The determination of Generation’s, ComEd’s, PECO’s and BGE’s retail energy sales to individual customers isbased on systematic readings of customer meters generally on a monthly basis. At the end of each month, amounts of energy delivered tocustomers since the date of the last meter reading are estimated, and corresponding unbilled revenue is recorded. The measurement ofunbilled revenue is affected by the following factors: daily customer usage measured by generation or gas throughput volume, customerusage by class, losses of energy during delivery to customers and applicable customer rates. Increases or decreases in volumes delivered tothe utilities’ customers and favorable or unfavorable rate mix due to changes in usage patterns in customer classes in the period could besignificant to the calculation of unbilled revenue. In addition, volumes may fluctuate monthly as a result of customers electing to use analternate supplier, which could be 111Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. significant to the calculation of unbilled revenue since unbilled commodity receivables are not recorded for these customers. Changes in thetiming of meter reading schedules and the number and type of customers scheduled for each meter reading date would also have an effect onthe measurement of unbilled revenue; however, total operating revenues would remain materially unchanged. See Note 6 of the Combined Notes to Consolidated Financial Statements for additional information. Regulated Transmission & Distribution Revenues. ComEd’s EIMA distribution formula rate tariff provides for annualreconciliations to the distribution revenue requirement. As of the balance sheet dates, ComEd has recorded its best estimates of thedistribution revenue impact resulting from changes in rates that ComEd believes are probable of approval by the ICC in accordance with theformula rate mechanism. Estimates are based upon actual costs incurred and investments in rate base for the period and the rates of returnon common equity and associated regulatory capital structure allowed under the applicable tariff. The estimated reconciliation can be affectedby, among other things, variances in costs incurred and investments made and actions by regulators or courts. ComEd’s and BGE’s FERC transmission formula rate tariffs provide for annual reconciliations to the transmission revenuerequirements. As of the balance sheet dates, ComEd and BGE have recorded the best estimate of their respective transmission revenueimpact resulting from changes in rates that ComEd and BGE believe are probable of approval by FERC in accordance with the formula ratemechanism. Estimates are based upon actual costs incurred and investments in rate base for the period and the rates of return on commonequity and associated regulatory capital structure allowed under the applicable tariff. The estimated reconciliation can be affected by, amongother things, variances in costs incurred and investments made and actions by regulators or courts. Allowance for Uncollectible Accounts (Exelon, Generation, ComEd, PECO and BGE) The allowance for uncollectible accounts reflects the Registrants’ best estimates of losses on the accounts receivable balances. ForGeneration, the allowance is based on accounts receivable aging historical experience and other currently available information. ComEd andPECO estimate the allowance for uncollectible accounts on customer receivables by applying loss rates developed specifically for eachcompany to the outstanding receivable balance by risk segment. Risk segments represent a group of customers with similar credit qualityindicators that are computed based on various attributes, including delinquency of their balances and payment history. Loss rates applied tothe accounts receivable balances are based on historical average charge-offs as a percentage of accounts receivable in each risk segment.BGE estimates the allowance for uncollectible accounts on customer receivables by assigning reserve factors for each aging bucket. Thesepercentages were derived from a study of billing progression which determined the reserve factors by aging bucket. ComEd, PECO and BGEcustomers’ accounts are generally considered delinquent if the amount billed is not received by the time the next bill is issued, whichnormally occurs on a monthly basis. ComEd, PECO and BGE customer accounts are written off consistent with approved regulatoryrequirements. ComEd’s, PECO’s and BGE’s provisions for uncollectible accounts will continue to be affected by changes in volume, pricesand economic conditions as well as changes in ICC, PAPUC and MDPSC regulations, respectively.

Net Income Attributable to Membership Interest Year Ended December 31, 2013 Compared to Year Ended December 31, 2012. Generation’s net income attributable tomembership interest increased compared to the same period in 2012 primarily due to higher revenues, net of purchased power and fuelexpense, lower operating and maintenance expense and higher earnings from Generation’s interest in CENG; partially offset by impairmentof certain generating assets, higher depreciation expense, higher property taxes, and higher interest expense. The increase in revenues, netor purchased power and fuel expense was primarily due to increased capacity prices and higher nuclear volume partially offset by lowerrealized energy prices, higher nuclear fuel costs, and lower mark-to-market gains in 2013. The decrease in operating and maintenanceexpense was largely due to 2012 costs associated with a settlement with FERC in 2012 and decreases in transaction costs and employee-related costs associated with the merger. Year Ended December 31, 2012 Compared to Year Ended December 31, 2011. Generation’s net income attributable tomembership interest decreased compared to the same period in 2012 primarily due to higher operating expenses, the loss on the sale ofBrandon Shores, Wagner and C.P. Crane (collectively Maryland generating stations) and the amortization of acquired energy contractsrecorded at fair value at the merger date; offset by higher revenues, net of purchased power and fuel expense and favorable NDT fundperformance. The increase in operating expenses was due to the addition of Constellation’s financial results from March 12, 2012, costsrelated to a 2012 settlement with FERC and transaction and employee-related severance costs associated with the merger. The increase inrevenues, net of purchased power and fuel expense was also primarily due to the merger. See Note 4 for additional information regarding theloss on the sale of three Maryland generating stations.

ComEd believes that revenues net of purchased powerexpense is a useful measurement because it provides information that can be used to evaluate its operational performance. In general, ComEd only earns marginbased on the delivery and transmission of electricity. ComEd has included its discussion of revenues net of purchased power expense below as a complement to thefinancial information provided in accordance with GAAP. However, revenues net of purchased power expense is not a presentation defined under GAAP and maynot be comparable to other companies’ presentations or deemed more useful than the GAAP information provided elsewhere in this report. Net Income Year Ended December 31, 2013, Compared to Year Ended December 31, 2012. ComEd’s net income for the year endedDecember 31, 2013, was lower than the same period in 2012, primarily due to the remeasurement of Exelon’s like-kind exchange taxposition, partially offset by increased electric distribution revenues, including the impacts of Senate Bill 9, and increased transmissionrevenues. See Note 3—Regulatory Matters and Note 14—Income Taxes of the Combined Notes to Consolidated Financial Statements foradditional information. Year Ended December 31, 2012, Compared to Year Ended December 31, 2011. ComEd’s net income for the year endedDecember 31, 2012, was lower than the same period in 2011, primarily due to increased operating and maintenance expenses, partiallyoffset by increased electric distribution revenues and increased transmission revenues. Operating 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 commodityprocurement costs and participation in customer choice programs. ComEd is permitted to recover electricity procurement costs from retailcustomers without mark-up. Therefore, fluctuations in electricity procurement costs have no impact on revenues net of purchased powerexpense. See Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information onComEd’s electricity procurement process. 123(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Customer choice programsdo not impact ComEd’s volume of deliveries, but do affect ComEd’s operating revenues related to supplied energy, which is fully offset inpurchased power expense. Therefore, customer choice programs have no impact on revenues net of purchased power expense. The number of retail customers participating in customer choice programs was 2,630,185, 1,627,150 and 380,262 at December 31,2013, 2012 and 2011, respectively, representing 68%, 43% and 10% of total retail customers, respectively. Retail energy purchased fromcompetitive electric generation suppliers represented 81%, 65% and 56% of ComEd’s retail kWh sales for the years ended December 31,2013, 2012 and 2011, respectively. During 2012, the City of Chicago and approximately 240 Illinois municipalities, including governmentalentities such as townships and counties, approved referenda regarding electric supply aggregation. The referenda allowed governmentalofficials to identify and sign contracts with competitive electric generation suppliers on behalf of the eligible retail customers in thecommunity, while also allowing customers to opt-out of the municipal aggregation program. As of December 31, 2013, there areapproximately 330 municipalities that have approved a municipal aggregation referendum in the ComEd service territory. As a result,approximately 69% of residential usage as of December 31, 2013 is being supplied by competitive electric generation suppliers, and ComEdestimates that over 80% of that usage resulted from municipal aggregation activities. The changes in ComEd’s revenues net of purchased power expense for the year ended 2013 compared to the same period in 2012consisted of the following: Increase(Decrease) Weather $(17) Volume (2) Electric distribution revenues, including impacts of Senate Bill 9 168 Discrete impacts of the 2012 Distribution Rate Case Order 13 Transmission revenues 14 Regulatory required programs 20 Uncollectible accounts recovery, net (58) Other 16 Total increase $154 Weather. The demand for electricity is affected by weather conditions. Very warm weather in summer months and very cold weather inother months are referred to as “favorable weather conditions” because these weather conditions result in increased customer usage.Conversely, mild weather reduces demand. For the year ended December 31, 2013, the increase in revenues net of purchased powerexpense was offset by unfavorable weather conditions as a result of the mild weather in 2013, compared to the same period in 2012. 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 ComEd’s service territorywith cooling degree days generally having a more significant impact to ComEd, particularly during the summer months. The changes inheating and cooling degree days in ComEd’s service territory for the years ended December 31, 2013 and 2012 consisted of the following: % Change Heating and Cooling Degree-Days 2013 2012 Normal From 2012 From Normal Twelve Months Ended December 31, Heating Degree-Days 6,603 5,065 6,341 30.4% 4.1% Cooling Degree-Days 933 1,324 842 (29.5)% 10.8% 124Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Revenues net of purchased power expense decreased as a result of lower delivery volume, exclusive of the effects of weather,for the year ended December 31, 2013, reflecting decreased average usage per residential customer as compared to the same period in 2012. Electric Distribution Revenues. EIMA provides for a performance-based formula rate tariff, which requires an annual reconciliation ofthe revenue requirement in effect to the actual costs that the ICC determines are prudently and reasonably incurred in a given year.Distribution revenues vary from year to year based upon fluctuations in the underlying costs, investments being recovered and other billingdeterminants. During the year ended December 31, 2013, ComEd recorded increased revenues of $168 million, primarily due to increasedcapital investments, increased operating expenses, and higher allowed return on common equity, including the impacts of Senate Bill 9.These amounts exclude the discrete impacts of the 2012 Distribution Rate Case Orders, discussed separately below. See Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statements for additional information. Discrete Impacts of the 2012 Distribution Rate Case Orders. On October 3, 2012, the ICC issued its final order related to ComEd’s2011 formula rate proceeding under EIMA (Rehearing Order), which reestablished ComEd’s position on the return on its pension asset,resulting in an increase to revenues in 2013. See Note 3—Regulatory Matters of the Combined Notes to Consolidated Financial Statementsfor additional information. Transmission Revenues. ComEd’s transmission rates are established based on a FERC-approved formula. ComEd’s most recentannual formula rate update, filed in April 2013, reflects 2012 actual costs plus forecasted 2013 capital additions. Transmission revenues varyfrom year to year based upon fluctuations in the underlying costs, investments being recovered and other billing determinants, such as thehighest daily peak load from the previous calendar year. During the year ended December 31, 2013, ComEd recorded increased revenues of$14 million primarily due to increased capital investments and higher operating expenses. See Note 3—Regulatory Matters of the CombinedNotes to Consolidated Financial Statements for additional information. Regulatory Required Programs. Revenues related to regulatory required programs are recoveries from customers for costs of variouslegislative and regulatory programs on a full and current basis through approved regulated rates. Programs include ComEd’s energyefficiency and demand response and purchased power administrative costs. An equal and offsetting amount has been reflected in operatingand maintenance expense during the periods presented. See the operating and maintenance expense discussion below for additionalinformation on included programs. Uncollectible Accounts Recovery, Net.

PECO believes revenues net of purchased power expense and revenues net of fuel expense are useful measurements of its performance because they provideinformation that can be used to evaluate its net revenues from operations. PECO has included the analysis below as a complement to the financial informationprovided in accordance with GAAP. However, revenues net of purchased power expense and revenue net of fuel expense figures are not a presentation definedunder GAAP and may not be comparable to other companies’ presentations or more useful than the GAAP information provided elsewhere in this report. Net Income Year Ended December 31, 2013 Compared to Year Ended December 31, 2012. The increase in net income was driven primarilyby lower operating and maintenance expense partially offset by an increase in income taxes. Year Ended December 31, 2012 Compared to Year Ended December 31, 2011. The decrease in net income was driven primarilyby lower operating revenues net of purchased power and fuel expense and increased storm costs. The decrease in revenues net of purchasedpower and fuel expense was primarily related to unfavorable weather and a decline in electric load. The decrease to net income was partiallyoffset by lower taxes other than income, interest expense and income taxes. Operating Revenues Net of Purchased Power and Fuel Expense Electric and gas revenues and purchased power and fuel expense are affected by fluctuations in commodity procurement costs.PECO’s electric supply and natural gas cost rates charged to customers are subject to adjustments at least quarterly that are designed torecover or refund the difference between the actual cost of electric supply and natural gas and the amount included in rates 130(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Therefore, fluctuations in electric supply and natural gas procurement costshave no impact on electric and gas revenues net of purchased power and fuel expense. Electric and gas revenues and purchased power and fuel expense are also affected by fluctuations in participation in the customer choiceprogram. All PECO customers have the choice to purchase electricity and gas from competitive electric generation and natural gas suppliers,respectively. The customer’s choice of suppliers does not impact the volume of deliveries, but affects revenues collected from customersrelated to supplied energy and natural gas service. Customer choice program activity has no impact on electric and gas revenues net ofpurchase power and fuel expense. The number of retail customers purchasing energy from a competitive electric generation supplier was531,500, 496,500, and 387,600 at December 31, 2013, 2012 and 2011, respectively. Retail deliveries purchased from competitive electricgeneration suppliers represented 68%, 66%, and 57% of PECO’s retail kWh sales for the years ended December 31, 2013, 2012 and 2011,respectively. The number of retail customers purchasing natural gas from a competitive natural gas supplier was 66,400, 53,600, and24,800 at December 31, 2013, 2012 and 2011, respectively. Retail deliveries purchased from competitive natural gas suppliers represented19%, 16%, and 11% of PECO’s mmcf sales for the years ended December 31, 2013, 2012 and 2011, respectively. The changes in PECO’s operating revenues net of purchased power and fuel expense for the year ended December 31, 2013compared to the same period in 2012 consisted of the following: Increase (Decrease) Electric Gas Total Weather $6 $31 $37 Volume (3) (3) (6) Pricing (14) 2 (12) Regulatory required programs (6) — (6) Gross receipts tax (8) — (8) Gas distribution tax repair — (8) (8) Other (7) (1) (8) Total decrease $(32) $21 $(11) Weather The demand for electricity and gas is affected by weather conditions. With respect to the electric business, very warm weather insummer months and, with respect to the electric and gas businesses, very cold weather in winter months are referred to as “favorableweather conditions” because these weather conditions result in increased deliveries of electricity and gas. Conversely, mild weather reducesdemand. Operating revenues net of purchased power and fuel expense were higher due to the impact of favorable 2013 winter weatherconditions. 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 year ended December 31, 2013 compared to the sameperiod in 2012 and normal weather consisted of the following: % Change Heating and Cooling Degree-Days 2013 2012 Normal From 2012 From Normal Twelve Months Ended December 31, Heating Degree-Days 4,474 3,747 4,603 19.4% (2.8)% Cooling Degree-Days 1,411 1,603 1,301 (12.0)% 8.5% 131Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Volume The decrease in electric revenues net of purchased power expense related to delivery volume, exclusive of the effects of weather,reflects the impact of energy efficiency initiatives on customer usages as well as a shift in the volume profile across classes from higherpriced classes to lower priced classes, partially offset by the oil refineries returning to full production in 2013 as well as moderate economicgrowth. The decrease in gas revenues net of fuel expense related to delivery volume, exclusive of the effects of weather, primarily reflects adecline in Residential use per customer. Pricing The decrease in electric operating revenues net of purchased power expense as a result of pricing is primarily attributable to loweroverall effective rates due to increased usage across all major customer classes. Regulatory Required Programs This represents the change in operating revenues collected under approved riders to recover costs incurred for the smart meter, energyefficiency and consumer education programs as well as the administrative costs for the GSA and AEPS programs. The riders are designed toprovide full and current cost recovery as well as a return. The offsetting costs of these programs are included in operating and maintenanceexpense, depreciation and amortization expense and income taxes. Refer to the operating and maintenance expense discussion below foradditional information on included programs. Gross Receipts Tax GRT is an excise tax on total electric revenues. As a result of decreases in operating revenues compared to 2012, GRT decreased.Equal and offsetting decreases in GRT have been reflected in taxes other than income. Gas Distribution Tax Repair The decrease in gas distribution tax repair reflects the 2012 tax benefit received from prior period gas distribution repairs for the 2011 taxyear.

BGE believes revenues net of purchased power and fuel expense are useful measurements of its performance because they provide information that can beused to evaluate its net revenues from operations. BGE has included the analysis below as a complement to the financial information provided in accordance withGAAP. However, revenues net of purchased power and fuel expense figures are not a presentation defined under GAAP and may not be comparable to othercompanies’ presentations or more useful than the GAAP information provided elsewhere in this report. Net Income Year Ended December 31, 2013 Compared to Year Ended December 31, 2012. The increase in net income was driven primarilyby higher distribution rates as a result of the 2012 rate order issued by MDPSC and decreased operating revenues net of purchased powerand fuel expense in 2012 related to the accrual of the residential customer rate credit provided as a condition of the MDPSC’s approval ofExelon’s merger with Constellation. Additionally, the increase in net income was also driven by higher operating and maintenance expensesin 2012, primarily related to BGE’s accrual of its portion of the charitable contributions to be provided as a condition of the MDPSC’s approvalof the merger and lower storm restoration costs in 2013. Year Ended December 31, 2012 Compared to Year Ended December 31, 2011.

None of the customer rate credit, the charitablecontributions, or the transaction costs are recoverable from BGE’s customers. Operating Revenues Net of Purchased Power and Fuel Expense There are certain drivers to operating revenue that are offset by their impact on purchased power expense and fuel expense, such ascommodity procurement costs and programs allowing customers to select a competitive electric or natural gas supplier. Electric and gasrevenues and purchased power and fuel expense are affected by fluctuations in commodity procurement costs. BGE’s electric and naturalgas rates charged to customers are subject to periodic adjustments that are designed to recover or refund the difference between the actualcost of purchased electric power and purchased natural gas and the amount included in rates in accordance with the MDPSC’s market-basedSOS and gas commodity programs, respectively. The number of customers electing to select a competitive electric generation supplier affects electric SOS revenues and purchasedpower expense. The number of customers electing to select a competitive natural gas supplier affects gas cost adjustment revenues andpurchased natural gas expense. All BGE customers have the choice to purchase energy from a competitive electric generation supplier. Thiscustomer choice of electric generation suppliers does not impact the volume of deliveries, but affects revenue collected from customersrelated to SOS. The number of retail customers purchasing electricity from a competitive electric generation supplier was 399,000, 362,000and 314,000 at December 31, 2013, 2012 and 2011, respectively, representing 32%, 29% and 25% of total retail customers, respectively.Retail deliveries purchased from competitive electric generation suppliers represented 61%, 60% and 58% of BGE’s retail kWh sales for theyears ended December 31, 2013, 2012 and 2011, respectively. The number of retail customers purchasing natural gas from a competitivenatural gas supplier was 172,000, 143,000 and 118,000 at December 31, 2013, 2012 and 2011, respectively, representing 26%, 22% and18% of total retail customers, respectively. Retail deliveries purchased from competitive natural gas suppliers represented 54%, 56% and52% of BGE’s retail mmcf sales for the years ended December 31, 2013, 2012 and 2011, respectively. The changes in BGE’s operating revenues net of purchased power and fuel expense for the year ended December 31, 2013 comparedto the same period in 2012 consisted of the following: Increase (Decrease) Electric Gas Total 2012 Residential customer rate credit $82 $31 $113 Pricing 69 24 93 Regulatory program cost recovery 36 6 42 Other 26 4 30 Total increase $213 $65 $278 (a)In accordance with the MDPSC order approving Exelon’s merger with Constellation, the residential customer rate credit is not recoverable from BGE’s customers.Exelon made a $66 million equity contribution to BGE in the second quarter of 2012 to fund the after-tax amount of the rate credit as directed in the MDPSC orderapproving the merger transaction. Revenue Decoupling. The demand for electricity and gas is affected by weather and usage conditions. The MDPSC has allowed BGEto record a monthly adjustment to its electric and gas distribution revenues from all residential customers, commercial electric customers,the majority of large industrial electric customers, and all firm service gas customers to eliminate the effect of abnormal weather and usagepatterns per customer on BGE’s electric and gas distribution volumes, thereby recovering a specified dollar amount of distribution revenuesper customer, by customer class, 138(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. regardless of changes in consumption levels. This allows BGE to recognize revenues at MDPSC-approved levels per customer, regardless ofwhat BGE’s actual distribution volumes were for a billing period. Therefore, while these revenues are affected by customer growth, they willnot be affected by actual weather or usage conditions. BGE bills or credits impacted customers in subsequent months for the differencebetween approved revenue levels under revenue decoupling and actual customer billings. Heating and cooling degree days are quantitative indices that reflect the demand for energy needed to heat a home or business. Normalweather is determined based on historical average heating and cooling degree days for a 30-year period in BGE’s service territory. Thechanges in heating degree days in BGE’s service territory for the year ended December 31, 2013 compared to the same period in 2012 andnormal weather consisted of the following: Heating and Cooling Degree-Days 2013 2012 Normal % Change From 2012 From Normal Twelve Months Ended December 31, Heating Degree-Days 4,744 3,960 4,661 19.8% 1.8% Cooling Degree-Days 869 1,022 864 (15.0)% 0.6% 2012 Residential Customer Rate Credit. The increase in operating revenues net of purchased power and fuel expense for the year ended December 31, 2013 compared to thesame period in 2012 was due to the residential customer rate credit provided in 2012 as a result of the MDPSC’s order approving Exelon’smerger with Constellation. Pricing. The increase in operating revenues net of purchased power and fuel expense as a result of pricing for the year ended December 31,2013 compared to the same period in 2012 was primarily due to the impact of the new electric and natural gas distribution rates charged tocustomers that became effective February 23, 2013 and December 13, 2013 in accordance with the MDPSC approved electric and naturalgas distribution rate case order. See Note 3—Regulatory Matters of the Combined Notes to the Consolidated Financial Statements for furtherinformation. Regulatory Required Programs. This represents the change in revenues collected under approved riders to recover costs incurred for the energy efficiency and demandresponse programs as well as administrative and commercial and industrial customer bad debt costs for SOS. The riders are designed toprovide full recovery, as well as a return in certain instances. The costs of these programs are included in operating and maintenanceexpense, depreciation and amortization expense and taxes other than income taxes.

Liquidity and Capital Resources Exelon’s and Generation’s prior year activity presented below includes the activity of Constellation, and BGE in the case of Exelon,from the merger effective date of March 12, 2012 through December 31, 2012. Exelon’s and Generation’s activity for 2011 is unadjusted forthe effects of the merger. BGE’s prior year activity presented below includes its activity for the 12 months ended December 31, 2012 and2011. The Registrants’ operating and capital expenditures requirements are provided by internally generated cash flows from operations aswell as funds from external sources in the capital markets and through bank borrowings. The Registrants’ businesses are capital intensiveand require considerable capital resources. Each Registrant’s access to external financing on reasonable terms depends on its credit ratingsand current overall capital market business conditions, including that of the utility industry in general. If these conditions deteriorate to theextent that the Registrants no longer have access to the capital markets at reasonable terms, Exelon, Generation, ComEd, PECO and BGEhave access to unsecured revolving credit facilities with aggregate bank commitments of $0.5 billion, $5.3 billion, $1.0 billion, $0.6 billionand $0.6 billion, respectively. The Registrants’ revolving credit facilities are in place until 2018. In addition, Generation has $0.4 billion inbilateral facilities with banks which expire in January 2015, December 2015 and March 2016. The Registrants utilize their credit facilities tosupport their commercial paper programs, provide for other short-term borrowings and to issue letters of credit. See the “Credit Matters”section below for further discussion. The Registrants expect cash flows to be sufficient to meet operating expenses, financing costs andcapital 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. TheRegistrants spend a significant amount of cash on capital improvements and construction projects that have a long-term return oninvestment. Additionally, ComEd, PECO and BGE operate in rate-regulated environments in which the amount of new investment recoverymay be delayed or limited and where such recovery takes place over an extended period of time. See Note 13 of the Combined Notes toConsolidated Financial Statements for further discussion of the Registrants’ debt and credit agreements. 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 andservices to customers. Generation’s future cash flows from operating activities may be affected by future demand for and market prices ofenergy and its ability to continue to produce and supply power at competitive costs as well as to obtain collections from customers. ComEd’s, PECO’s and BGE’s cash flows from operating activities primarily result from the transmission and distribution of electricityand, in the case of PECO and BGE, gas distribution services. ComEd’s, PECO’s and BGE’s distribution services are provided to anestablished and diverse base of retail customers. ComEd’s, PECO’s and BGE’s future cash flows may be affected by the economy, weatherconditions, future legislative initiatives, future regulatory proceedings with respect to their rates or operations, competitive suppliers, and theirability to achieve operating cost reductions. See Notes 3 and 22 of the Combined Notes to Consolidated Financial Statements for further discussion of regulatory and legalproceedings and proposed legislation. 144Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Pension and Other Postretirement Benefits Management considers various factors when making pension funding decisions, including actuarially determined minimumcontribution requirements under ERISA, contributions required to avoid benefit restrictions and at-risk status as defined by the PensionProtection Act of 2006, management of the pension obligation and regulatory implications. On July 6, 2012, President Obama signed intolaw the Moving Ahead for Progress in the Twenty-first Century Act, which contains a pension funding provision that results in lower pensioncontributions in the near term while increasing the premiums pension plans pay to the Pension Benefit Guaranty Corporation. Certainprovisions of the law were applied in 2012 while others take effect in 2013. The estimated impacts of the law are reflected in the projectedpension contributions below. Exelon expects to contribute approximately $264 million to its pension plans in 2014, of which Generation, ComEd, PECO and BGEexpect to contribute $118 million, $119 million, $11 million and $0 million, respectively. See Note 16 of the Combined Notes to ConsolidatedFinancial Statements for the Registrants’ 2013 and 2012 pension contributions. Unlike the qualified pension plans, Exelon’s other postretirement plans are not subject to regulatory minimum contributionrequirements. Management considers several factors in determining the level of contributions to Exelon’s other postretirement benefit plans,including levels of benefit claims paid and regulatory implications (amounts deemed prudent to meet regulatory expectations and best assurecontinued recovery). Exelon expects to contribute approximately $430 million to the other postretirement benefit plans in 2014, of whichGeneration, ComEd, PECO and BGE expect to contribute $168 million, $197 million, $19 million and $17 million, respectively. See Note16 of the Combined Notes to Consolidated Financial Statements for the Registrants’ 2013 and 2012 other postretirement benefitcontributions. See the “Contractual Obligations” section below for management’s estimated future pension and other postretirement benefitscontributions. Tax Matters The Registrants’ future cash flows from operating activities may be affected by the following tax matters: • Exelon, Generation, ComEd, PECO and BGE expect to receive tax refunds of approximately $380 million, $60 million, $320million, $10 million and $20 million, respectively, between 2014 and 2015. • Given the current economic environment, state and local governments are facing increasing financial challenges, which mayincrease the risk of additional income tax levies, property taxes and other taxes. • In September 2012, PECO filed an application with the IRS to change its method of accounting for gas distribution repairs for the2011 tax year. The newly adopted method results in a cash tax benefit in 2012 of approximately $38 million and $41 million atExelon and PECO, respectively. Exelon currently anticipates that the IRS will issue industry guidance in the near future. See Note3 of the Combined Notes to Consolidated Financial Statements for discussion regarding the regulatory treatment of PECO’s taxbenefits from the application of the method change. 145Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Cash flows provided by operations for 2013, 2012 and 2011 by Registrant were as follows: 2013 2012 2011 Exelon $6,343 $6,131 $4,853 Generation 3,887 3,581 3,313 ComEd 1,218 1,334 836 PECO 747 878 818 BGE 561 485 476 (a)Exelon’s and Generation’s prior year activity includes the activity of Constellation, and BGE in the case of Exelon, from the merger effective date of March 12, 2012through December 31, 2012. Exelon’s and Generation’s activity for 2011 is unadjusted for the effects of the merger. BGE’s prior year activity includes its activity for the12 months ended December 31, 2012 and 2011. Changes in Exelon’s, Generation’s, ComEd’s, PECO’s and BGE’s cash flows from operations were generally consistent withchanges in each Registrant’s respective results of operations, as adjusted by changes in working capital in the normal course of business. Inaddition, significant operating cash flow impacts for the Registrants for 2013, 2012 and 2011 were as follows: Generation • During 2013, 2012 and 2011, Generation had net (payments) receipts of counterparty collateral of $162 million, $95 million and$(410) million, respectively. Net payments during 2013 and 2012 were primarily due to market conditions that resulted in changesto Generation’s net mark-to-market position. Depending upon whether Generation is in a net mark-to-market liability or assetposition, collateral may be required to be posted with or collected from its counterparties. This collateral may be in various forms,such as cash, which may be obtained through the issuance of commercial paper, or letters of credit. • During 2013, 2012 and 2011, Generation’s accounts receivable from ComEd increased (decreased) by $(16) million, $(15) millionand $12 million, respectively, primarily due to changes in receivables for energy purchases related to its SFC, ICC-approved RFPcontracts and financial swap contract. 146(a)(b) (a)(a)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The level of option activity in a given year may vary due to several factors,including changes in market conditions as well as changes in hedging strategy. ComEd • During 2013, 2012 and 2011, ComEd’s net payables to Generation for energy purchases related to its supplier forward contract,ICC-approved RFP contracts and financial swap contract settlements increased (decreased) by $(16) million, $(15) million and $12million, respectively. During 2013, 2012 and 2011, ComEd’s payables to other energy suppliers for energy purchases increased(decreased) by $35 million, $20 million and $(43) million, respectively. • During 2013, 2012, and 2012, ComEd received $53 million, $37 million and $63 million, respectively, of incremental cashcollateral from PJM due to variations in its energy transmission activity levels. As of December 31, 2013 and December 31, 2012,ComEd had cash collateral remaining at PJM of $0M and $53 million, respectively. PECO • During 2013, 2012 and 2011, PECO’s payables to Generation for energy purchases increased (decreased) by $(17) million, $17million and $(210) million, respectively, and payables to other energy suppliers for energy purchases increased (decreased) by $33million, $(22) million and $97 million, respectively.

ComEd expects to file an updated investment plan with the ICC in April, 2014.(e)Other primarily consists of corporate operations and BSC.(f)Exelon’s and Generation’s prior year activity includes the activity of Constellation, and BGE in the case of Exelon, from the merger effective date of March 12, 2012through December 31, 2012. Exelon’s and Generation’s activity for 2011 is unadjusted for the effects of the merger. BGE’s prior year activity includes its activity for the12 months ended December 31, 2012 and 2011. Projected capital expenditures and other investments are subject to periodic review and revision to reflect changes in economicconditions and other factors. Generation Approximately 38% and 11% of the projected 2014 capital expenditures at Generation are for the acquisition of nuclear fuel andinvestments in renewable energy generation, including Antelope Valley construction costs, respectively, with the remaining amountsreflecting additions and upgrades to existing facilities (including material condition improvements during nuclear refueling outages). Alsoincluded in the projected 2014 capital expenditures are a portion of the costs of a series of planned power uprates across Generation’s nuclearfleet. See “EXELON CORPORATION—Executive Overview,” for more information on nuclear uprates. On November 30, 2012, a subsidiary of Generation sold three Maryland generating stations and associated assets to Raven PowerHoldings LLC, a subsidiary of Riverstone Holdings LLC, and received net proceeds of approximately $371. In addition, Generation willbegin to make cash payments of approximately $31 million to Raven Power Holdings LLC over a twelve-month period beginning in June2014. In 2012, Generation incurred transaction costs of approximately $15 million through the date of closing of the transaction. The sale willgenerate approximately $195 million of cash tax benefits, of which $155 million will be realized in periods through 2014 with the balance tobe received in later years. Therefore, Generation expects net after-tax cash sale proceeds of approximately $495 million through 2014 andapproximately $36 million in subsequent years. ComEd, PECO and BGE Approximately 91%, 72% and 89% of the projected 2014 capital expenditures at ComEd, PECO and BGE, respectively, are forcontinuing projects to maintain and improve operations, including enhancing reliability and adding capacity to the transmission anddistribution systems such as ComEd’s reliability related investments required under EIMA, and ComEd’s, PECO’s and BGE’s 148(b) (a)(f)(c)(f) (d)(f)(e)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

PECO and BGE capital expenditures include investments related to their respective smart meter program and SGIG project, net ofDOE expected reimbursements. The remaining amounts are for capital additions to support new business and customer growth. See Notes3 and 7 of the Combined Notes to Consolidated Financial Statements for additional information. In 2010, NERC provided guidance to transmission owners, including ComEd, PECO, and BGE, that recommends the completion ofperformance assessments of their transmission lines, with the highest priority lines assessed by December 31, 2011, medium priority linesby December 31, 2012, and the lowest priority lines by December 31, 2013. In compliance with this guidance, ComEd, PECO and BGEsubmitted their most recent bi-annual reports to NERC in January 2014. ComEd, PECO and BGE will incur incremental capitalexpenditures associated with this guidance following the completion of the assessments. Specific projects and expenditures are identified asthe assessments are completed. ComEd’s, PECO’s and BGE’s forecasted 2014 capital expenditures above reflect capital spending forremediation to be completed in 2014. ComEd, PECO and BGE anticipate that they will fund capital expenditures with internally generated funds and borrowings, includingComEd’s capital expenditures associated with EIMA as further discussed in Note 3 of the Combined Notes to Consolidated FinancialStatements.

Credit Matters Market Conditions The Registrants fund liquidity needs for capital investment, working capital, energy hedging and other financial commitments throughcash flows from continuing operations, public debt offerings, commercial paper markets and large, diversified credit facilities. The creditfacilities include $8.4 billion in aggregate total commitments of which $6.6 billion was available as of December 31, 2013, and of which nofinancial institution has more than 8% of the aggregate commitments for Exelon, Generation, ComEd, PECO and BGE. The Registrantshad access to the commercial paper market during 2013 to fund their short-term liquidity needs, when necessary. The Registrants routinelyreview the sufficiency of their liquidity position, including appropriate sizing of credit facility commitments, by performing various stress testscenarios, such as commodity price movements, increases in margin-related transactions, changes in hedging levels and the impacts ofhypothetical credit downgrades. The Registrants have continued to closely monitor events in the financial markets and the financialinstitutions associated with the credit facilities, including monitoring credit ratings and outlooks, credit default swap levels, capital raising andmerger activity. See PART I. ITEM 1A Risk Factors for further 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 sufficientliquidity.

See Note 3 of the Combined Notes to Consolidated Financial Statements for additionalinformation. Exelon’s ability to pay dividends on its common stock depends on the receipt of dividends paid by its operating subsidiaries. Thepayments of dividends to Exelon by its subsidiaries in turn depend on their results of operations and cash flows and other items affectingretained earnings. The Federal Power Act declares it to be unlawful for any officer or director of any public utility “to participate in the makingor paying of any dividends of such public utility from any funds properly included in capital account.” In addition, under Illinois law, ComEdmay not pay any dividend on its stock, unless, among other things, its earnings and earned surplus are sufficient to declare and pay adividend after provision is made for reasonable and proper reserves, or unless ComEd has specific authorization from the ICC. BGE issubject to certain dividend restrictions established by the MDPSC. First, BGE is prohibited from paying a dividend on its common sharesthrough the end of 2014. Second, BGE is prohibited from paying a dividend on its common shares if (a) after the dividend payment, BGE’sequity ratio would be below 48% as calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s senior unsecured credit ratingis rated by two of the three major credit rating agencies below investment grade. Finally, BGE must notify the MDPSC that it intends todeclare a dividend on its common shares at least 30 days before such a dividend is paid. There are no other limitations on BGE payingcommon stock dividends unless: (1) BGE elects to defer interest payments on the 6.20% Deferrable Interest Subordinated Debentures due2043, and any deferred interest remains unpaid; or (2) any dividends (and any redemption payments) due on BGE’s preference stock havenot been paid.

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 ratesand equity prices. Exelon’s RMC approves risk management policies and objectives for risk assessment, control and valuation, counterpartycredit approval, and the monitoring and reporting of risk exposures. The RMC is chaired by the chief risk officer and includes the chiefexecutive officer, chief financial officer, corporate controller, general counsel, treasurer, vice president of strategy, vice president of auditservices and officers representing Exelon’s business units. The RMC reports to the risk oversight committee of the Exelon board of directorson the scope of the risk management activities. Commodity Price Risk (Exelon, Generation, ComEd, PECO and BGE) 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 amount of energy Exelongenerates differs from the amount of energy it has contracted to sell, Exelon has price risk from commodity price movements. Exelon seeksto mitigate its commodity price risk through the sale and purchase of electricity, fossil fuel, and other commodities. Generation Normal Operations and Hedging Activities. Electricity available from Generation’s owned or contracted generation supply in excessof Generation’s obligations to customers, including portions of ComEd’s, PECO’s and BGE’s retail load, is sold into the wholesale markets.To reduce price risk caused by market fluctuations, Generation enters into non-derivative contracts as well as derivative contracts, includingforwards, futures, swaps, and options, with approved counterparties to hedge anticipated exposures. Generation believes these instrumentsrepresent economic hedges that mitigate exposure to fluctuations in commodity prices. Generation expects the settlement of the majority ofits economic hedges will occur during 2014 through 2016. In general, increases and decreases in forward market prices have a positive and negative impact, respectively, on Generation’s ownedand contracted generation positions which have not been hedged. Generation hedges commodity risk on a ratable basis over the three yearsleading to the spot market. As of December 31, 2013, the percentage of expected generation hedged for the major reportable segments was92%-95%, 62%-65% and 30%-33% for 2014, 2015 and 2016, respectively. The percentage of expected generation hedged is the amount ofequivalent sales divided by the expected generation. Expected generation represents the amount of energy estimated to be generated orpurchased through owned or contracted capacity. Equivalent sales represent all hedging products, which include economic hedges andcertain non-derivative contracts including 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 andfuel prices, which routinely change in the market. Market price risk exposure is the risk of a change in the value of unhedged positions. Theforecasted market price risk exposure for Generation’s entire non-trading portfolio associated with a $5 reduction in the annual averagearound-the-clock energy price based on December 31, 2013, market conditions and hedged position would be a decrease in pre-tax netincome of approximately $30 million, $520 million and $820 million, respectively, for 2014, 2015 and 2016.

Past financial performance is no guarantee of future results. adjusting power price assumptions while keeping all other price inputs constant. Generation expects to actively manage its portfolio tomitigate market price risk exposure for its unhedged position. Actual results could differ depending on the specific timing of, and marketsaffected by, price changes, as well as future changes in Generation’s portfolio. Proprietary Trading Activities. Generation also enters into certain energy-related derivatives for proprietary trading purposes.Proprietary trading includes all contracts entered into with the intent of benefiting from shifts or changes in market prices as opposed to thoseentered into with the intent of hedging or managing risk. Proprietary trading activities are subject to limits established by Exelon’s RMC. Theproprietary trading portfolio is subject to a risk management policy that includes stringent risk management limits, including volume, stoploss and Value-at-Risk (VaR) limits to manage exposure to market risk. Additionally, the Exelon risk management group and Exelon’s RMCmonitor the financial risks of the proprietary trading activities. The proprietary trading activities, which included physical volumes of 8,762GWh, 12,958 GWh, and 5,742 GWh for the years ended December 31, 2013, 2012 and 2011 respectively, are a complement toGeneration’s energy marketing portfolio, but represent a small portion of Generation’s overall revenue from energy marketing activities.Trading portfolio activity for the year ended December 31, 2013, resulted in pre-tax losses of $8 million due to net mark-to-market losses of$39 million and realized gains of $31 million. Generation uses a 95% confidence interval, assuming standard normal distribution, one dayholding period, one-tailed statistical measure in calculating its VaR. The daily VaR on proprietary trading activity averaged $1.0 million ofexposure during the year. Generation has not segregated proprietary trading activity within the following discussion because of the relativesize of the proprietary trading portfolio in comparison to Generation’s total gross margin from continuing operations for the year endedDecember 31, 2013 of $7,433 million. Fuel Procurement. Generation procures coal and natural gas through long-term and short-term contracts, and spot-market purchases.Nuclear fuel assemblies are obtained primarily through long-term contracts for uranium concentrates, and long-term contracts for conversionservices, enrichment services and fuel fabrication services. The supply markets for coal, natural gas, uranium concentrates and certainnuclear fuel services are subject to price fluctuations and availability restrictions. Supply market conditions may make Generation’sprocurement contracts subject to credit risk related to the potential non-performance of counterparties to deliver the contracted commodity orservice at the contracted prices. Approximately 60% of Generation’s uranium concentrate requirements from 2014 through 2018 are suppliedby three producers. In the event of non-performance by these or other suppliers, Generation believes that replacement uranium concentratescan 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 impact on Exelon’s and Generation’s results of operations, cash flows andfinancial positions. See Note 22 of the Combined Notes to Consolidated Financial Statements for additional information regarding uraniumand coal supply agreement matters. ComEd The financial swap contract between Generation and ComEd was deemed prudent by the Illinois Settlement Legislation, therebyensuring that ComEd would be entitled to receive full cost recovery in rates. The change in fair value each period was recorded by ComEdwith an offset to a regulatory asset or liability. This financial swap contract between Generation and ComEd expired on May 31, 2013. Allrealized impacts have been included in Generation’s and ComEd’s results of operations. ComEd entered into 20-year contracts for renewable energy and RECs beginning in June 2012. ComEd is permitted to recover itsrenewable energy and REC costs from retail customers with no mark-up. The annual commitments represent the maximum settlementswith suppliers for renewable energy and RECs under the existing contract terms.

Past financial performance is no guarantee of future results. 2012, ComEd’s commitments under the existing long-term contracts were reduced for the June 2013 through May 2014 procurementperiod. The ICC’s December 18, 2013 order approved the reduction of ComEd’s commitments under the long-term contracts for the June2014 through May 2015 procurement period, however the amount of the reduction will not be finalized and approved by the ICC until March2014. See Notes 3 and 12 of the Combined Notes to Consolidated Financial Statements for additional information regarding energyprocurement and derivatives. PECO PECO has contracts to procure electric supply that were executed through the competitive procurement process outlined in its PAPUC-approved DSP Programs, which are further discussed in Note 3 of the Combined Notes to the Consolidated Financial Statements. PECO’sfull requirements contracts and block contracts, which are considered derivatives, qualify for the normal purchases and normal sales scopeexception under current derivative authoritative guidance and as a result, are accounted for on an accrual basis of accounting. Under the DSPPrograms, PECO is permitted to recover its electric supply procurement costs from retail customers with no mark-up. PECO has also entered into derivative natural gas contracts, which either qualify for the normal purchases and normal sales exceptionor have no mark-to-market balances because the derivatives are index priced, to hedge its long-term price risk in the natural gas market.PECO’s hedging program for natural gas procurement has no direct impact on its financial position or results of operations as natural gascosts are fully recovered from customers under the PGC. PECO does not enter into derivatives for speculative or proprietary trading purposes. For additional information on these contracts, seeNote 12 of the Combined Notes to Consolidated Financial Statements. BGE BGE procures electric supply for default service customers through full requirements contracts pursuant to BGE’s MDPSC-approvedSOS program. BGE’s full requirements contracts that are considered derivatives qualify for the normal purchases and normal sales scopeexception under current derivative authoritative guidance and as a result, are accounted for on an accrual basis of accounting. Under the SOSprogram, BGE is permitted to recover its electricity procurement costs from retail customers, plus an administrative fee which includes ashareholder return component and an incremental cost component. However, through December 2016, BGE provides all residential electriccustomers a credit for the residential shareholder return component of the administrative charge. BGE has also entered into derivative natural gas contracts, which qualify for the normal purchases and normal sales scope exception,to hedge its price risk in the natural gas market. The hedging program for natural gas procurement has no direct impact on BGE’s financialposition. However, under BGE’s market-based rates incentive mechanism, BGE’s actual cost of gas is compared to a market index (ameasure of the market price of gas in a given period). The difference between BGE’s actual cost and the market index is shared equallybetween shareholders and customers. BGE does not enter into derivatives for speculative or proprietary trading purposes. For additional information on these contracts, seeNote 12 of the Combined Notes to Consolidated Financial Statements.

ComEd iscurrently obligated to provide service to all electric customers within its franchised territory. ComEd records a provision for uncollectibleaccounts, based upon historical experience, to provide for the potential loss from nonpayment by these customers. See Note 1 of theCombined Notes to Consolidated Financial Statements for the allowance for uncollectible accounts policy. ComEd is permitted to recover itscosts of procuring energy through the Illinois Settlement Legislation as well as the ICC-approved procurement tariffs. ComEd will monitornonpayment from customers and will make any necessary adjustments to the provision for uncollectible accounts. The Illinois SettlementLegislation prohibits utilities, including ComEd, from terminating electric service to a residential electric space heat customer due tononpayment between December 1 of any year through March 1 of the following year. ComEd’s ability to disconnect non space-heatingresidential customers is also impacted by certain weather restrictions, at any time of year, under the Illinois Public Utilities Act. ComEd willmonitor the impact of its disconnection practices and will make any necessary adjustments to the provision for uncollectible accounts.ComEd did not have any customers representing over 10% of its revenues as of December 31, 2013. See Note 3 of the Combined Notes toConsolidated Financial Statements for additional information regarding ComEd’s recently approved tariffs to adjust rates annually through arider mechanism to reflect increases or decreases in annual uncollectible accounts expense. ComEd’s power procurement contracts provide suppliers with a certain amount of unsecured credit. The credit position is based onforward market prices compared to the benchmark prices. The benchmark prices are the forward prices of energy projected through thecontract term and are set at the point of supplier bid submittals. If the forward market price of energy exceeds the benchmark price, thesuppliers are required to post collateral for the secured credit portion after adjusting for any unpaid deliveries and unsecured credit allowedunder the contract. The unsecured credit used by the suppliers represents ComEd’s net credit exposure. ComEd’s counterparty credit risk ismitigated by its ability to recover realized energy costs through customer rates. As of December 31, 2013, ComEd’s credit exposure to energysuppliers was immaterial. PECO Credit risk for PECO is managed by credit and collection policies, which are consistent with state regulatory requirements. PECO iscurrently obligated to provide service to all retail electric customers within its franchised territory. PECO records a provision for uncollectibleaccounts to provide for the potential loss from nonpayment by these customers. See Note 1 of the Combined Notes to Consolidated FinancialStatements for the allowance for uncollectible accounts policy. In accordance with PAPUC regulations, after November 30 and before April 1,an electric distribution utility or natural gas distribution utility shall not terminate service to customers with household incomes at or below250% of the Federal poverty level. PECO’s provision for uncollectible accounts will continue to be affected by changes in prices as well aschanges in PAPUC regulations. PECO did not have any customers representing over 10% of its revenues as of December 31, 2013. PECO’s supplier master agreements that govern the terms of its DSP Program contracts, which define a supplier’s performanceassurance requirements, allow a supplier to meet its credit requirements with a certain amount of unsecured credit. The amount ofunsecured credit is determined based on the supplier’s lowest credit rating from the major credit rating agencies and the supplier’s tangiblenet worth. The credit position is based on the initial market price, which is the forward price of energy on the day a transaction is executed,compared to the current forward price curve for energy. To the extent that the forward price curve for energy exceeds the initial market price,the supplier is required to post collateral to the extent the credit exposure is greater than the supplier’s unsecured credit limit. As ofDecember 31, 2013, PECO had no net credit exposure with suppliers. 168Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. PECO does not obtain cash collateral from suppliers under its natural gas supply and asset management agreements. As ofDecember 31, 2013, PECO had credit exposure of $9 million under its natural gas supply and asset management agreements withinvestment grade suppliers. BGE Credit risk for BGE is managed by credit and collection policies, which are consistent with state regulatory requirements. BGE iscurrently obligated to provide service to all electric customers within its franchised territory. BGE records a provision for uncollectible accountsto provide for the potential loss from nonpayment by these customers. BGE will monitor nonpayment from customers and will make anynecessary adjustments to the provision for uncollectible accounts. See Note 1 of the Combined Notes to Consolidated Financial Statementsfor uncollectible accounts policy. MDPSC regulations prohibit BGE from terminating service to residential customers due to nonpaymentfrom November 1 through March 31 if the forecasted temperature is 32 degrees or below for the subsequent 72 hour period. BGE is alsoprohibited by the Maryland Public Utilities Article and MDPSC regulations from terminating service to residential customers due tononpayment if the forecasted temperature is 95 degrees or above for the subsequent 72 hour period. BGE did not have any customersrepresenting over 10% of its revenues as of December 31, 2013. BGE’s full requirement wholesale electric power agreements that govern the terms of its electric supply procurement contracts, whichdefine a supplier’s performance assurance requirements, allow a supplier, or its guarantor, to meet its credit requirements with a certainamount of unsecured credit. The amount of unsecured credit is determined based on the supplier’s lowest credit rating from the major creditrating agencies and the supplier’s tangible net worth, subject to an unsecured credit cap. The credit position is based on the initial marketprice, which is the forward price of energy on the day a transaction is executed, compared to the current forward price curve for energy. To theextent that the forward price curve for energy exceeds the initial market price, the supplier is required to post collateral to the extent the creditexposure is greater than the supplier’s unsecured credit limit. The seller’s credit exposure is calculated each business day. As ofDecember 31, 2013, BGE had no net credit exposure with suppliers. BGE’s regulated gas business is exposed to market-price risk. This market-price risk is mitigated by BGE’s recovery of its costs toprocure natural gas through a gas cost adjustment clause approved by the MDPSC. BGE does make off-system sales after BGE hassatisfied its customers’ demands, which are not covered by the gas cost adjustment clause. At December 31, 2013, BGE had credit exposureof $14 million related to off-system sales which is mitigated by parental guarantees, letters of credit, or right to offset clauses within othercontracts with those third-party suppliers. Collateral (Exelon, Generation, ComEd, PECO and BGE) Generation As part of the normal course of business, Generation routinely enters into physical or financial contracts for the sale and purchase ofelectricity, fossil fuel and other commodities. These contracts either contain express provisions or otherwise permit Generation and itscounterparties to demand adequate assurance of future performance when there are reasonable grounds for doing so. In accordance with thecontracts and applicable law, if Generation is downgraded by a credit rating agency, especially if such downgrade is to a level belowinvestment grade, it is possible that a counterparty would attempt to rely on such a downgrade as a basis for making a demand for adequateassurance of future performance. Depending on Generation’s net position with a counterparty, the demand could be for the posting ofcollateral. In the absence of expressly agreed-to provisions that specify the collateral that must be provided, collateral requested will be afunction of the facts and circumstances of the situation at the time of the demand. In this case, Generation believes an amount 169Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

See Note 12 of the Combined Notes to Consolidated FinancialStatements for information regarding collateral requirements. Generation sells output through bilateral contracts. The bilateral contracts are subject to credit risk, which relates to the ability ofcounterparties to meet their contractual payment obligations. Any failure to collect these payments from counterparties could have a materialimpact on Exelon’s and Generation’s results of operations, cash flows and financial position. As market prices rise above contracted pricelevels, Generation is required to post collateral with purchasers; as market prices fall below contracted price levels, counterparties arerequired to post collateral with Generation. In order to post collateral, Generation depends on access to bank credit facilities which serve asliquidity sources to fund collateral requirements. See Note 13 of the Combined Notes to Consolidated Financial Statements for additionalinformation. As of December 31, 2013, Generation had cash collateral of $72 million posted and cash collateral held of $206 million forcounterparties with derivative positions, of which $144 million in net cash collateral deposits were offset against mark-to-market assets andliabilities. As of December 31, 2013, $10 million of cash collateral posted was not offset against net derivative positions because it was notassociated with energy-related derivatives. As of December 31, 2012, Generation had cash collateral held of $499 million and cash collateralposted of $527 million for counterparties with derivative positions, of which $31 million in net cash collateral deposits were offset againstmark-to-market assets and liabilities. As of December 31, 2012, $3 million of cash collateral received was not offset against net mark-to-market assets and liabilities because it was not associated with energy-related derivatives. See Note 22 of the Combined Notes toConsolidated Financial Statements for information regarding the letters of credit supporting the cash collateral. ComEd As of December 31, 2013, ComEd held immaterial amounts of cash and letters of credit for the purpose of collateral from suppliers inassociation with energy procurement contracts and held approximately $19 million in the form of cash for both annual and long-termrenewable energy contracts. See Notes 3 and 12 of the Combined Notes to Consolidated Financial Statements for further information. PECO As of December 31, 2013, PECO was not required to post collateral under its energy and natural gas procurement contracts. See Note12 of the Combined Notes to Consolidated Financial Statements for further information. BGE BGE is not required to post collateral under its electric supply contracts. As of December 31, 2013, BGE was not required to postcollateral under its natural gas procurement contracts, nor was it holding collateral under its electric supply and natural gas procurementcontracts. See Note 12 of the Combined Notes to Consolidated Financial Statements for further information. RTOs and ISOs (Exelon, Generation, ComEd, PECO and BGE) Generation, ComEd, PECO and BGE participate in all, or some, of the established, real-time energy markets that are administered byPJM, ISO-NE, ISO-NY, CAISO, MISO, SPP, AESO, OIESO and ERCOT. In these areas, power is traded through bilateral agreementsbetween buyers and sellers 170Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. and on the spot markets that are operated by the RTOs or ISOs, as applicable. In areas where there is no spot market, electricity ispurchased and sold solely through bilateral agreements. For sales into the spot markets administered by an RTO or ISO, the RTO or ISOmaintains financial assurance policies that are established and enforced by those administrators. The credit policies of the RTOs and ISOsmay, under certain circumstances, require that losses arising from the default of one member on spot market transactions be shared by theremaining participants. Non-performance or non-payment by a major counterparty could result in a material adverse impact on theRegistrants’ results of operations, cash flows and financial positions. Exchange Traded Transactions (Exelon and Generation) Generation enters into commodity transactions on NYMEX, ICE and the Nodal exchange. The NYMEX, ICE and Nodal exchangeclearinghouses act as the counterparty to each trade. Transactions on the NYMEX, ICE and Nodal exchange must adhere to comprehensivecollateral and margining requirements. As a result, transactions on NYMEX, ICE and Nodal exchange are significantly collateralized andhave limited counterparty credit risk. Long-Term Leases (Exelon) Exelon’s consolidated balance sheet, as of December 31, 2013, included a $698 million net investment in coal-fired plants in Georgiaand Texas subject to long-term leases. This investment represents the estimated residual value of leased assets at the end of the respectivelease terms of $1,465 million, less unearned income of $767 million. The lease agreements provide the lessees with fixed purchase optionsat the end of the lease terms. If the lessees do not exercise the fixed purchase options, Exelon has the ability to require the lessees to returnthe leasehold interests or to arrange for a third-party to bid on a service contract for a period following the lease term. If Exelon chooses theservice contract option, the leasehold interests will be returned to Exelon at the end of the term of the service contract. In any event, Exelonwill be subject to residual value risk if the lessees do not exercise the fixed purchase options. This risk is partially mitigated by the fair valueof the scheduled payments under the service contract. However, such payments are not guaranteed. Further, the term of the service contractis less than the expected remaining useful life of the plants and, therefore, Exelon’s exposure to residual value risk will not be mitigated bypayments under the service contract in this remaining period. Lessee performance under the lease agreements is supported by collateral andcredit enhancement measures. Management regularly evaluates the creditworthiness of Exelon’s counterparties to these long-term leases.Exelon monitors the continuing credit quality of the credit enhancement party. Pursuant to the applicable accounting guidance, Exelon is required to review the estimated residual values of its direct financing leaseinvestments at least annually and, if the review indicates a fair value below the carrying value and the decline is determined to be other thantemporary, must record an impairment charge in the period the estimate changed. Based on the review performed in the second quarter of2013, the estimated residual value of one of Exelon’s direct financing leases experienced an other than temporary decline resulting in a $14million pre-tax impairment charge in the second quarter of 2013. See Note 8 of the Combined Notes to Consolidated Financial Statementsfor further information. Through December 31, 2013, no events have occurred that would require Exelon to review the estimated residualvalues of its direct financing lease investments subsequent to the review performed in the second quarter of 2013. Interest-Rate Risk (Exelon, Generation, ComEd, PECO and BGE) The Registrants use a combination of fixed-rate and variable-rate debt to manage interest rate exposure. The Registrants may alsoutilize fixed-to-floating interest rate swaps, which are typically designated as fair value hedges, as a means to manage their interest rateexposure. In addition, the 171Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Registrants may utilize interest rate derivatives to lock in rate levels in anticipation of future financings, which are typically designated ascash flow hedges. These strategies are employed to manage interest rate risks. At December 31, 2013, Exelon had $1,425 million ofnotional amounts of fixed-to-floating hedges outstanding and $190 million of notional amounts of floating-to-fixed hedges outstanding.Assuming the fair value and cash flow interest rate hedges are 100% effective, a hypothetical 50 bps increase in the interest rates associatedwith unhedged variable-rate debt (excluding Commercial Paper) and fixed-to-floating swaps would result in an approximate $5 milliondecrease in Exelon Consolidated pre-tax income for the year ended December 31, 2013. Equity Price Risk (Exelon and Generation) Exelon and Generation maintain trust funds, as required by the NRC, to fund certain costs of decommissioning Generation’s nuclearplants. As of December 31, 2013, Generation’s decommissioning trust funds are reflected at fair value on 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 forinflationary increases in decommissioning costs; however, the equity securities in the trust funds are exposed to price fluctuations in equitymarkets, and the value of fixed-rate, fixed-income securities are exposed to changes in interest rates. Generation actively monitors theinvestment performance of the trust funds and periodically reviews asset allocation in accordance with Generation’s NDT fund investmentpolicy. A hypothetical 10% increase in interest rates and decrease in equity prices would result in a $482 million reduction in the fair value ofthe trust assets. This calculation holds all other variables constant and assumes only the discussed changes in interest rates and equityprices. See ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONSfor further discussion of equity price risk as a result of the current capital and credit market conditions. 172Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Basis of Presentation (Exelon, Generation, ComEd, PECO and BGE) This is a combined annual report of Exelon, Generation, ComEd, PECO and BGE. The Notes to the Consolidated FinancialStatements apply to Exelon, Generation, ComEd, PECO and BGE as indicated parenthetically next to each corresponding disclosure. Whenappropriate, Exelon, Generation, ComEd, PECO and BGE are named specifically for their related activities and disclosures. Exelon did not apply push-down accounting to BGE and BGE continued to be subject to reporting requirements as an SEC registrant.The information disclosed for BGE represents the activity of the standalone entity for the twelve months ended December 31, 2013, 2012and 2011 and the financial position as of December 31, 2013 and December 31, 2012. However, for Exelon’s consolidated financialreporting, Exelon is reporting BGE activity from the acquisition date of March 12, 2012 through December 31, 2013. Each of the Registrant’s Consolidated Financial Statements includes the accounts of its subsidiaries. All intercompany transactionshave been eliminated. 216Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Through its business services subsidiary, BSC, Exelon provides its subsidiaries with a variety of support services at cost, includinglegal, human resources, financial, information technology and supply management services. The costs of BSC, including support services,are directly charged or allocated to the applicable subsidiaries using a cost-causative allocation method. Corporate governance-type costs thatcannot be directly assigned are allocated based on a Modified Massachusetts Formula, which is a method that utilizes a combination of grossrevenues, total assets and direct labor costs for the allocation base. The results of Exelon’s corporate operations are presented as “Other”within the consolidated financial statements and include intercompany eliminations unless otherwise disclosed. Exelon owns 100% of all of its significant consolidated subsidiaries, either directly or indirectly, except for ComEd, of which Exelonowns more than 99%, and BGE, of which Exelon owns 100% of the common stock but none of BGE’s preference stock. Exelon ownednone of PECO’s preferred securities, which PECO redeemed in 2013. Exelon has reflected the third-party interests in ComEd, which totaledless than $1 million at December 31, 2013 and December 31, 2012, as equity, PECO’s preferred securities as preferred securities ofsubsidiary through their redemption in 2013, and BGE’s preference stock as BGE preference stock not subject to mandatory redemption inits consolidated financial statements. BGE is subject to some ring-fencing measures established by order of the MDPSC. As part of thisarrangement, BGE common stock is held directly by RF Holdco LLC, which is an indirect subsidiary of Exelon. GSS Holdings (BGEUtility), an unrelated party, holds a nominal non-economic interest in RF Holdco LLC with limited voting rights on specified matters. Generation owns 100% of all of its significant consolidated subsidiaries, either directly or indirectly, except for certain Exelon Windprojects, of which Generation holds a majority interest ranging from 94% to 99% for certain periods of time, and the remaining interests areincluded in non-controlling interest on Exelon’s and Generation’s Consolidated Balance Sheets. See Note 2 for further discussion ofExelon’s and Generation’s VIEs and the reversionary interests of the non-controlling members for certain of these projects. ComEd owns 100% of all of its significant consolidated subsidiaries, either directly or indirectly, except for RITELine Illinois, LLC, ofwhich ComEd owns 75% and an additional 12.5% is indirectly owned by Exelon. Exelon and ComEd have reflected the third-party interestsof 12.5% and 25%, respectively, in RITELine Illinois, LLC, which both totaled less than $1 million at December 31, 2013 and December 31,2012, as equity. Exelon consolidates the accounts of entities in which Exelon has a controlling financial interest, after the elimination of intercompanytransactions. A controlling financial interest is evidenced by either a voting interest greater than 50% in which Exelon can exercise controlover the operations and policies of the investee, or the results of a model that identifies Exelon or one of its subsidiaries as the primarybeneficiary of a VIE. Where Exelon does not have a controlling financial interest in an entity, it applies proportional consolidation, equitymethod accounting or cost method accounting. Exelon applies proportionate consolidation when it has an undivided interest in an asset andis proportionately liable for its share of each liability associated with the asset. Exelon proportionately consolidates its undivided ownershipinterests in jointly owned electric plants and transmission facilities, as well as its undivided ownership interests in upstream natural gasexploration and production activities. Under proportionate consolidation, Exelon separately records its proportionate share of the assets,liabilities, revenues and expenses related to the undivided interest in the asset. Exelon applies equity method accounting when it hassignificant influence over an investee through an ownership in common stock, which generally approximates a 20% to 50% voting interest.Exelon applies equity method accounting 217Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) to certain investments and joint ventures, including the 50.01% interest in CENG, and certain financing trusts of ComEd, PECO, and BGE.Under the equity method, Exelon reports its interest in the entity as an investment and Exelon’s percentage share of the earnings from theentity as single line items in its financial statements. Exelon uses the cost method if it holds less than 20% of the common stock of an entity.Under the cost method, Exelon reports its investment at cost and recognizes income only to the extent Exelon receives dividends ordistributions. For the year ended December 31, 2013, BGE recorded a $2 million (pre-tax) correcting adjustment to decrease amortization expenserelated to regulatory assets that were originally recorded during 2012, an adjustment to decrease income tax expense by $4 million related tothe recognition and measurement of regulatory assets that should have been recorded in periods prior to 2013, and a $4 million (pre-tax)correcting adjustment to decrease operating and maintenance expense for an overstatement of BGE’s life insurance obligation related to post-employment benefits in prior years. For the year ended December 31, 2012, BGE recorded a $2 million (pre-tax) correcting adjustment toreduce electric distribution revenue related to decoupling of 2011 electric distribution revenue, a $3 million (pre-tax) correcting adjustment toincrease electric operations and maintenance expense related to capitalization of electric transmission costs, and a $5 million (pre-tax)correcting adjustment to interest expense to reflect the impacts of amendments of tax positions previously taken on prior-year consolidatedincome tax returns. In addition, ComEd identified a disclosure adjustment within the renewable energy credits and alternative energy creditssection of the 2012 Form 10-K Note 8—Intangible Assets which has been revised in Note 10 of this year’s report. Exelon, ComEd and BGEhave concluded these correcting adjustments are not material to its results of operations, cash flows, or financial positions for the yearsended December 31, 2013, and December 31, 2012, or any prior period. The accompanying consolidated financial statements have been prepared in accordance with GAAP for annual financial statements andin accordance with the instructions to Form 10-K and Regulation S-X promulgated by the SEC. Use of Estimates (Exelon, Generation, ComEd, PECO and BGE) The preparation of financial statements of each of the Registrants in conformity with GAAP requires management to make estimatesand assumptions that affect the amounts reported in the financial statements and accompanying notes. Areas in which significant estimateshave been made include, but are not limited to, the accounting for nuclear decommissioning costs and other AROs, pension and otherpostretirement benefits, the application of purchase accounting, inventory reserves, allowance for uncollectible accounts, goodwill and assetimpairments, derivative instruments, unamortized energy contracts, fixed asset depreciation, environmental costs and other losscontingencies, taxes and unbilled energy revenues. Actual results could differ from those estimates. Reclassifications (Exelon, ComEd, and BGE) Certain prior year amounts in Exelon’s and BGE’s Consolidated Statements of Operations and Cash Flows, and Exelon’s, ComEd’s,and BGE’s Consolidated Balance Sheets have been reclassified between line items for comparative purposes and correction of prior periodclassification errors identified in 2013. The reclassifications did not affect any of the Registrants’ net income or cash flows from operatingactivities. In 2013, Exelon and BGE corrected the presentation of interest expense related to BGE’s financing trust of $12 million and $16million, respectively, to be presented as Interest expense to 218Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) affiliates, net on their Statements of Operations and Comprehensive Income for the year ended December 31, 2012. BGE also reclassifiedthe related Accrued expenses of $4 million to Payables to affiliates on its December 31, 2012 Balance Sheet. Similar adjustments are alsoreflected in Note 22 – Related Party Transactions. Exelon and Generation also corrected amounts disclosed within Note 22 – Related PartyTransactions to increase Purchased power and fuel from affiliates by $114 million and to increase Payables to affiliates by $20 million. In2013, Generation corrected the presentation of interest expense related to certain debt of $75 million to be presented as Interest expense toaffiliates, net on its Statement of Operations and Comprehensive Income for the year ended December 31, 2012 and within Note 22 –Related Party Transactions. Accounting for the Effects of Regulation (Exelon, ComEd, PECO and BGE) Exelon, ComEd, PECO and BGE apply the authoritative guidance for accounting for certain types of regulation, which requiresComEd, PECO and BGE to record in their consolidated financial statements the effects of cost-based rate regulation for entities withregulated operations that meet the following criteria: 1) rates are established or approved by a third-party regulator; (2) rates are designed torecover the entities’ cost of providing services or products; and (3) there is a reasonable expectation that rates are set at levels that will recoverthe entities’ costs from customers. Exelon, ComEd, PECO and BGE account for their regulated operations in accordance with regulatory andlegislative guidance from the regulatory authorities having jurisdiction, principally the ICC, the PAPUC, and the MDPSC, in the cases ofComEd, PECO and BGE, respectively, under state public utility laws and the FERC under various Federal laws. Regulatory assets andliabilities are amortized and the related expense is recognized in the Consolidated Statements of Operations consistent with the recovery orrefund included in customer rates. Exelon believes that it is probable that its currently recorded regulatory assets and liabilities will berecovered and settled, respectively, in future rates. However, Exelon, ComEd, PECO and BGE continue to evaluate their respective abilitiesto apply the authoritative guidance for accounting for certain types of regulation, including consideration of current events in their respectiveregulatory and political environments. If a separable portion of ComEd’s, PECO’s or BGE’s business was no longer able to meet the criteriadiscussed above, the affected entities would be required to eliminate from their consolidated financial statements the effects of regulation forthat portion, which could have a material impact on their results of operations and financial positions. See Note 3—Regulatory Matters foradditional information. The Registrants treat the impacts of a final rate order received after the balance sheet date but prior to the issuance of the financialstatements as a non-recognized subsequent event, as the receipt of a final rate order is a separate and distinct event that has future impactson the parties affected by the order. Revenues (Exelon, Generation, ComEd, PECO and BGE) Operating Revenues. Operating revenues are recorded as service is rendered or energy is delivered to customers. At the end of eachmonth, the Registrants accrue an estimate for the unbilled amount of energy delivered or services provided to customers. ComEd records itsbest estimates of the distribution and transmission revenue impacts resulting from changes in rates that ComEd believes are probable ofapproval by the ICC and FERC in accordance with its formula rate mechanisms. BGE records its best estimate of the transmission revenueimpact resulting from changes in rates that BGE believes are probable of approval by FERC in accordance with its formula rate mechanism.See Note 3—Regulatory Matters and Note 6—Accounts Receivable for further information. RTOs and ISOs. In RTO and ISO markets that facilitate the dispatch of energy and energy-related products, the Registrants generallyreport sales and purchases conducted on a net hourly basis in 219Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) either revenues or purchased power on their Consolidated Statements of Operations, the classification of which depends on the net hourlyactivity. In addition, capacity revenue and expense classification is based on the net sale or purchase position of the Company in the differentRTOs and ISOs. Option Contracts, Swaps and Commodity Derivatives. Certain option contracts and swap arrangements that meet the definition ofderivative instruments are recorded at fair value with subsequent changes in fair value recognized as revenue or expense. The classificationof revenue or expense is based on the intent of the transaction. For example, gas transactions may be used to hedge the sale of power. Thiswill result in the change in fair value recorded through revenue. As of the merger date, Exelon and Generation have currently elected to de-designate all of their commodity cash flow hedge positions. As ComEd receives full cost recovery for energy procurement and related costsfrom retail customers, ComEd records the fair value of its energy swap contracts with unaffiliated suppliers as well as an offsetting regulatoryasset or liability on its Consolidated Balance Sheets. Refer to Note 3—Regulatory Matters and Note 12—Derivative Financial Instruments forfurther information. Proprietary Trading Activities. Exelon and Generation account for Generation’s trading activities under the provisions of theauthoritative guidance for accounting for contracts involved in energy trading and risk management activities, which require energy revenuesand costs related to energy trading contracts to be presented on a net basis in the income statement. Commodity derivatives used for tradingpurposes are accounted for using the mark-to-market method with unrealized gains and losses recognized in operating revenues. Refer toNote 12—Derivative Financial Instruments for further information. Income Taxes (Exelon, Generation, ComEd, PECO and BGE) Deferred Federal and state income taxes are provided on all significant temporary differences between the book basis and the tax basisof assets and liabilities and for tax benefits carried forward. Investment tax credits have been deferred on the Registrants’ ConsolidatedBalance Sheets and are recognized in book income over the life of the related property. In accordance with applicable authoritative guidance,the Registrants account for uncertain income tax positions using a benefit recognition model with a two-step approach; a more-likely-than-notrecognition 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 itstechnical merits, no benefit is recorded. Uncertain tax positions that relate only to timing of when an item is included on a tax return areconsidered to have met the recognition threshold. The Registrants recognize accrued interest related to unrecognized tax benefits in interestexpense or in other income and deductions (interest income) on their Consolidated Statements of Operations. Pursuant to the IRC and relevant state taxing authorities, Exelon and its subsidiaries file consolidated or combined income tax returnsfor Federal and certain state jurisdictions where allowed or required. See Note 14—Income Taxes for further information. Taxes Directly Imposed on Revenue-Producing Transactions (Exelon, Generation, ComEd, PECO and BGE) Exelon, Generation, ComEd, PECO and BGE collect certain taxes from customers such as sales and gross receipts taxes, along withother taxes, surcharges, and fees that are levied by state or local governments on the sale or distribution of gas and electricity. Some of thesetaxes are imposed on the customer, but paid by the Registrants, while others are imposed on the Registrants. Where these taxes 220Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) are imposed on the customer, such as sales taxes, they are reported on a net basis with no impact to the Consolidated Statements ofOperations and Comprehensive Income. However, where these taxes are imposed on the Registrants, such as gross receipts taxes or othersurcharges or fees, they are reported on a gross basis. Accordingly, revenues are recognized for the taxes collected from customers along withan offsetting expense. See Note 23—Supplemental Financial Information for Generation’s, ComEd’s, PECO’s and BGE’s utility taxes thatare presented on a gross basis. Cash and Cash Equivalents (Exelon, Generation, ComEd, PECO and BGE) The Registrants consider investments purchased with an original maturity of three months or less to be cash equivalents. Restricted Cash and Investments (Exelon, Generation, ComEd, PECO and BGE) Restricted cash and investments represent funds that are restricted to satisfy designated current liabilities. As of December 31, 2013and 2012, Exelon Corporate’s restricted cash and investments primarily represented restricted funds for payment of medical, dental, visionand long-term disability benefits. Additionally, Exelon Corporate has funds restricted for merger commitments. In addition, ExelonCorporate’s investments include its direct financing lease investments. As of December 31, 2013, Generation’s restricted cash andinvestments primarily included cash at Antelope Valley required for debt service and construction and cash at Continental Wind required fordebt service and financing of operation and maintenance of the underlying entities. As of December 31, 2012, Generation’s restricted cashprimarily included cash at Antelope Valley required for debt service and construction. As of December 31, 2013 and 2012, ComEd’s restrictedcash primarily represented cash collateral held from suppliers associated with ComEd’s REC procurement contracts. As of December 31,2013, PECO’s restricted cash primarily represented funds from the sales of assets that were subject to PECO’s mortgage indenture. As ofDecember 31, 2013 and 2012, BGE’s restricted cash primarily represented funds restricted at its consolidated variable interest entity forrepayment of rate stabilization bonds. Restricted cash and investments not available to satisfy current liabilities are classified as noncurrent assets. As of December 31, 2013and 2012, Exelon’s and Generation’s NDT funds, which are designated to satisfy future decommissioning obligations, were classified asnoncurrent assets. As of December 31, 2013, Exelon, Generation, ComEd, PECO and BGE had investments in Rabbi trusts classified asnoncurrent assets. Allowance for Uncollectible Accounts (Exelon, Generation, ComEd, PECO and BGE) The allowance for uncollectible accounts reflects the Registrants’ best estimates of losses on the accounts receivable balances. ForGeneration, the allowance is based on accounts receivable aging, historical experience and other currently available information. ComEd andPECO estimate the allowance for uncollectible accounts on customer receivables by applying loss rates developed specifically for eachcompany to the outstanding receivable balance by risk segment. Risk segments represent a group of customers with similar credit qualityindicators that are computed based on various attributes, including delinquency of their balances and payment history. Loss rates applied tothe accounts receivable balances are based on historical average charge-offs as a percentage of accounts receivable in each risksegment. BGE estimates the allowance for uncollectible accounts on customer receivables by assigning reserve factors for each agingbucket. These percentages were derived from a study of billing progression which determined the reserve factors by aging bucket. ComEd,PECO and BGE customers’ accounts are generally considered delinquent if the amount billed 221Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) is not received by the time the next bill is issued, which normally occurs on a monthly basis. ComEd, PECO and BGE customer accountsare written off consistent with approved regulatory requirements. ComEd’s, PECO’s and BGE’s provisions for uncollectible accounts willcontinue to be affected by changes in volume, prices and economic conditions as well as changes in ICC, PAPUC and MDPSC regulations,respectively. See Note 3—Regulatory Matters for additional information regarding the regulatory recovery of uncollectible accounts receivableat ComEd. Variable Interest Entities (Exelon, Generation, ComEd, PECO and BGE) Exelon accounts for its investments in and arrangements with VIEs based on the authoritative guidance which includes the followingspecific requirements: • requires an entity to qualitatively assess whether it should consolidate a VIE based on whether the entity (1) has the power to directmatters that most significantly impact the activities of the VIE, and (2) has the obligation to absorb losses or the right to receivebenefits of the VIE that could potentially be significant to the VIE, • 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 present separately on the face of its balance sheet (1) theassets of the consolidated VIE, if they can be used to only settle specific obligations of the consolidated VIE, and (2) the liabilities ofa consolidated VIE for which creditors do not have recourse to the general credit of the primary beneficiary. Based on the above accounting guidance, Exelon has adopted the following policies related to variable interest entities: • Exelon has presented separately on its Consolidated Balance Sheets, to the extent material, the assets of its consolidated VIEs thatcan only be used to settle specific obligations of the consolidated VIE, and the liabilities of Exelon’s consolidated VIEs for whichcreditors do not have recourse to Exelon’s general credit. • Exelon has qualitatively assessed whether the equity holders of the entity have the power to direct matters that most significantlyimpact the entity. See Note 2—Variable Interest Entities for additional information. Inventories (Exelon, Generation, ComEd, PECO and BGE) Inventory is recorded at the lower of weighted average cost or market. Provisions are recorded for excess and obsolete inventory. Fossil Fuel. Fossil fuel inventory includes the weighted average costs of stored natural gas, propane and oil. The costs of natural gas,propane, coal and oil are generally included in inventory when purchased and charged to fuel expense when used or sold. Materials and Supplies. Materials and supplies inventory generally includes the weighted average costs of transmission, distributionand generating plant materials. Materials are generally charged to inventory when purchased and expensed or capitalized to property, plantand equipment, as appropriate, when installed or used. 222Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Emission Allowances. Emission allowances are included in inventory (for emission allowances exercisable in the current year) andother deferred debits (for emission allowances that are exercisable beyond one year) and are carried at the lower of weighted average cost ormarket and charged to fuel expense as they are used in operations. Marketable Securities (Exelon, Generation, ComEd, PECO and BGE) All marketable securities are reported at fair value. Marketable securities held in the NDT funds, certain Generation Rabbi trustinvestments and BGE’s Rabbi trust investments are classified as trading securities and all other securities are classified as available-for-salesecurities. Realized and unrealized gains and losses, net of tax, on Generation’s NDT funds associated with the former ComEd and formerPECO nuclear generating units (Regulatory Agreement Units) are included in regulatory liabilities at Exelon, ComEd and PECO and innoncurrent payables to affiliates at Generation and in noncurrent receivables from affiliates at ComEd and PECO. Realized and unrealizedgains and losses, net of tax, on Generation’s NDT funds associated with the former AmerGen nuclear generating units, the Zion generatingstation and portions of the Peach Bottom nuclear generating units not subject to a regulatory agreement (Non-Regulatory Agreement Units)are included in earnings at Exelon and Generation. Realized and unrealized gains and losses, net of tax, on certain Generation Rabbi trustinvestments and BGE’s Rabbi trust investments are included in earnings at Exelon, Generation and BGE. Unrealized gains and losses, netof tax, for Generation’s, ComEd’s and PECO’s available-for-sale securities are reported in OCI. Any decline in the fair value of ComEd’s andPECO’s available-for-sale securities below the cost basis is reviewed to determine if such decline is other-than-temporary. If the decline isdetermined to be other-than-temporary, the cost basis of the available-for-sale securities is written down to fair value as a new cost basis andthe amount of the write-down is included in earnings. See Note 15—Asset Retirement Obligations for information regarding marketablesecurities held by NDT funds and Note 23—Supplemental Financial Information for additional information regarding ComEd’s and PECO’sregulatory assets and liabilities. Property, Plant and Equipment (Exelon, Generation, ComEd, PECO and BGE) Property, plant and equipment is recorded at original cost. Original cost includes labor, materials and construction overhead. Whenappropriate, original cost also includes capitalized interest for Generation and Exelon Corporate and AFUDC for regulated property at ComEd,PECO and BGE. The cost of repairs and maintenance, including planned major maintenance activities and minor replacements of property,is charged to maintenance expense as incurred. For constructed assets, Exelon capitalizes construction-related direct labor and material costs.ComEd, PECO and BGE also capitalized indirect construction costs including labor and related costs of departments associated withsupporting construction activities. Third parties reimburse ComEd, PECO and BGE for all or a portion of expenditures for certain capital projects. Such contributions inaid of construction costs (CIAC) are recorded as a reduction to Property, Plant and Equipment. DOE SGIG funds reimbursed to PECO andBGE are accounted for as CIAC. For Generation, upon retirement, the cost of property is charged to accumulated depreciation in accordance with the composite methodof depreciation. Upon replacement of an asset, the costs to remove the asset, net of salvage, are capitalized to gross plant when incurred aspart 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. 223Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) For ComEd, PECO and BGE, upon retirement, the cost of property, net of salvage, is charged to accumulated depreciation inaccordance with the composite method of depreciation. ComEd’s and BGE’s depreciation expense includes the estimated cost of dismantlingand removing plant from service upon retirement, which is consistent with each utility’s regulatory recovery method. ComEd’s and BGE’sactual incurred removal costs are applied against a related regulatory liability. PECO’s removal costs are capitalized to accumulateddepreciation when incurred, and recorded to depreciation expense over the life of the new asset constructed consistent with PECO’sregulatory recovery method. Generation’s oil and gas exploration and production activities consist of working interests in gas producing fields. Generation accountsfor these activities under the successful efforts method of accounting. Acquisition, development and exploration costs are capitalized. Costs ofdrilling exploratory wells are initially capitalized and later charged to expense if reserves are not discovered or deemed not to be commerciallyviable. Other exploratory costs are charged to expense when incurred. See Note 7—Property, Plant and Equipment, Note 9—Jointly Owned Electric Utility Plant and Note 23—Supplemental FinancialInformation 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-productionmethod. The estimated disposal cost of SNF is established per the Standard Waste Contract with the DOE and is expensed through fuelexpense at one mill ($0.001) per kWh of net nuclear generation. 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 22—Commitments and Contingencies for additionalinformation regarding the SNF disposal fee. Nuclear Outage Costs (Exelon and Generation) Costs associated with nuclear outages, including planned major maintenance activities, are expensed to operating and maintenanceexpense or capitalized to property, plant and equipment (based on the nature of the activities) in the period incurred. New Site Development Costs (Exelon and Generation) New site development costs represent the costs incurred in the assessment and design of new power generating facilities. Such costsare capitalized when management considers project completion to be probable, primarily based on management’s determination that theproject is economically and operationally feasible, management and/or the Exelon board of directors has approved the project and hascommitted to a plan to develop it, and Exelon and Generation have received the required regulatory approvals or management believes thereceipt of required regulatory approvals is probable. Capitalized development costs are charged to Operating and maintenance expense whenproject completion is no longer probable. At December 31, 2013 and 2012, there were no material capitalized development costs for projectsnot yet under construction included in Property, plant and equipment, net on Exelon’s and Generation’s Consolidated Balance Sheets.Approximately $10 million, $4 million and $2 million of costs were expensed by Exelon and Generation for the years ended December 31,2013, 2012, and 2011, respectively. These costs primarily related to the possible development of new renewable energy projects. 224Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Capitalized Software Costs (Exelon, Generation, ComEd, PECO and BGE) Costs incurred during the application development stage of software projects that are internally developed or purchased for operationaluse are capitalized. 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 orpursuant to prescribed regulatory requirements. The following table presents net unamortized capitalized software costs and amortization ofcapitalized software costs by year: Net unamortized software costs Exelon Generation ComEd PECO BGE December 31, 2013 $479 $129 $101 $71 $155 December 31, 2012 499 143 105 63 157 Amortization of capitalized software costs Exelon Generation ComEd PECO BGE 2013 $198 $67 $52 $33 $36 2012 208 81 56 30 32 2011 122 41 50 25 25 (a)Exelon activity for the year ended December 31, 2012 includes the results of Constellation and BGE for March 12, 2012—December 31, 2012. Generation activity forthe year ended December 31, 2012 includes the results of Constellation for March 12, 2012—December 31, 2012. BGE activity represents the activity for the yearsended December 31, 2012 and 2011. Depreciation, Depletion and Amortization (Exelon, Generation, ComEd, PECO and BGE) Except for the amortization of nuclear fuel, depreciation is generally recorded over the estimated service lives of property, plant andequipment on a straight-line basis using the composite method. ComEd’s and BGE’s depreciation includes a provision for estimatedremoval costs as authorized by the respective regulators. The estimated service lives for ComEd, PECO and BGE are primarily based on theaverage service lives from the most recent depreciation study for each respective company. The estimated service lives of the nuclear-fuelgenerating facilities are based on the remaining useful lives of the stations, which assume a 20-year license renewal extension of theoperating licenses (to the extent that such renewal has not yet been granted) for all of Generation’s operating nuclear generating stationsexcept for Oyster Creek. The estimated service lives of the hydroelectric generating facilities are based on the remaining useful lives of thestations, which assume a license renewal extension of the operating licenses. The estimated service lives of the fossil fuel and otherrenewable generating facilities are based on the remaining useful lives of the stations, which Generation periodically evaluates based onfeasibility assessments taking into account economic and capital requirement considerations. See Note 7—Property, Plant and Equipment for further information regarding depreciation. Depletion of oil and gas exploration and production activities is recorded using the units-of-production method over the remaining life ofthe estimated proved reserves at the field level for acquisition costs and over the remaining life of proved developed reserves at the field levelfor development costs. The estimates for gas reserves are based on internal calculations. Amortization of regulatory assets is recorded over the recovery period specified in the related legislation or regulatory agreement. Whenthe recovery or refund period is less than one year, amortization is recorded to the line item in which the deferred cost would have originallybeen recorded 225(a) (a)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

With exception of income tax-related regulatoryassets, when the recovery period is more than one year, the amortization is recorded to Depreciation and amortization in the Registrants’Consolidated Statements of Operations and Comprehensive Income. For income tax related regulatory assets, amortization is generallyrecorded to Income tax expense 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’snuclear fuel, Generation’s ARC and the amortization of ComEd’s, PECO’s and BGE’s regulatory assets. Asset Retirement Obligations (Exelon, Generation, ComEd, PECO and BGE) The authoritative guidance for accounting for AROs requires the recognition of a liability for a legal obligation to perform an assetretirement activity even though the timing and/or method of settlement may be conditional on a future event. To estimate itsdecommissioning obligation related to its nuclear generating stations, Generation uses a probability-weighted, discounted cash flow modelwhich, on a unit-by-unit basis, considers multiple outcome scenarios that include significant estimates and assumptions, and are based ondecommissioning cost studies, cost escalation rates, probabilistic cash flow models and discount rates. Generation generally updates itsARO annually during the third quarter, unless circumstances warrant more frequent updates, based on its review of updated cost studiesand its annual evaluation of cost escalation factors and probabilities assigned to various scenarios. Decommissioning cost studies areupdated, on a rotational basis, for each of Generation’s nuclear units at least every five years. The liabilities associated with Exelon’s non-nuclear AROs are adjusted on an ongoing rotational basis, at least once every five years. Changes to the recorded value of an ARO resultfrom the passage of new laws and regulations, revisions to either the timing or amount of estimates of undiscounted cash flows, andestimates of cost escalation factors. AROs are accreted each year to reflect the time value of money for these present value obligationsthrough a charge to operating and maintenance expense in the Consolidated Statements of Operations or, in the case of the majority ofComEd’s, PECO’s, and BGE’s accretion, through an increase to regulatory assets. See Note 15—Asset Retirement Obligations foradditional information. Capitalized Interest and AFUDC (Exelon, Generation, ComEd, PECO and BGE) 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. Exelon, ComEd, PECO and BGE apply the authoritative guidance for accounting for certain types of regulation to calculate AFUDC,which 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 AFUDC that is included in interest expense for debt-relatedfunds and other income and deductions for equity-related funds. The rates used for capitalizing AFUDC are computed under a methodprescribed by regulatory authorities. 226Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Guarantees (Exelon, Generation, ComEd, PECO and BGE) The Registrants recognize, at the inception of a guarantee, a liability for the fair market value of the obligations they have undertaken inissuing the guarantee, including the ongoing obligation to perform over the term of the guarantee in the event that the specified triggeringevents or conditions occur. The liability that is initially recognized at the inception of the guarantee is reduced as the Registrants are released from risk under theguarantee. Depending on the nature of the guarantee, the release from risk of the Registrant may be recognized only upon the expiration orsettlement of the guarantee or by a systematic and rational amortization method over the term of the guarantee. See Note 22—Commitments and Contingencies for additional information. Asset Impairments (Exelon, Generation, ComEd, PECO and BGE) Long-Lived Assets. The Registrants evaluate the carrying value of their long-lived assets or asset groups, excluding goodwill, whencircumstances indicate the carrying value of those assets may not be recoverable. The Registrants determine if long-lived assets and assetgroups are impaired by comparing their undiscounted expected future cash flows to their carrying value. Cash flows for long-lived assets andasset groups are determined at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets andliabilities. Cash flows from Generation plant assets are generally evaluated at a regional portfolio level along with cash flows generated fromGeneration’s supply and risk management activities, including cash flows from contracts that are recorded as intangible contract assets andliabilities on the balance sheet. In certain cases generation assets may be evaluated on an individual basis where those assets are contractedon a long-term basis with a third party and operations are independent of other generation assets (typically contracted renewables). Impairment may occur when the carrying value of the asset or asset group exceeds the future undiscounted cash flows. When theundiscounted cash flow analysis indicates a long-lived asset or 227 (a)(a) (a)(b)(b)(b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) 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. Conditions that could have an adverse impact on the expected future cash flows and the fair value of the long-lived assets and assetgroups include, among other factors, a deteriorating business climate, including energy prices and market conditions, revisions to regulatorylaws, or plans to dispose of a long-lived asset significantly before the end of its useful life. See Note 8—Impairment of Long-Lived Assets foradditional information. Goodwill. Goodwill represents the excess of the purchase price paid over the estimated fair value of the assets acquired and liabilitiesassumed in the acquisition of a business. Goodwill is not amortized, but is tested for impairment at least annually or on an interim basis ifan 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 10—Intangible Assets for additional information regarding Exelon’s and ComEd’s goodwill. Equity Method Investments. Exelon and Generation regularly monitor and evaluate equity method investments to determinewhether they are impaired. An impairment is recorded when the investment has experienced a decline in value that is not temporary innature. Additionally, if the project in which Generation holds an investment recognizes an impairment loss, Exelon and Generation wouldrecord their proportionate share of that impairment loss and evaluate the investment for an other than temporary decline in value. Direct Financing Lease Investments. Direct financing lease investments represent the estimated residual values of leased coal-firedplants in Georgia and Texas. Exelon reviews the estimated residual values of its direct financing lease investments and records animpairment charge if the review indicates an other than temporary decline in the fair value of the residual values below their carrying values.See Note 8—Impairment of Long-Lived Assets for additional information. Derivative Financial Instruments (Exelon, Generation, ComEd, PECO and BGE) All derivatives are recognized on the balance sheet at their fair value unless they qualify for certain exceptions, including the normalpurchases and normal sales exception. Additionally, derivatives that qualify and are designated for hedge accounting are classified as eitherhedges of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge) or hedges of a forecastedtransaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For fair valuehedges, changes in fair values for both the derivative and the underlying hedged exposure are recognized in earnings each period. For cashflow hedges, the portion of the derivative gain or loss that is effective in offsetting the change in the cost or value of the underlying exposure isdeferred in accumulated OCI and later reclassified into earnings when the underlying transaction occurs. Gains and losses from theineffective portion of any hedge are recognized in earnings immediately. For derivative contracts intended to serve as economic hedges andthat are not designated or do not qualify for hedge accounting or the normal purchases and normal sales exception, changes in the fair valueof the derivatives are recognized in earnings each period. Amounts classified in earnings are included in revenue, purchased power and fuel,interest expense or other, net on the Consolidated Statement of Operations based on the activity the transaction is economically hedging. Forenergy-related derivatives entered into for proprietary trading purposes, which are subject to Exelon’s Risk Management Policy, changes inthe fair value of the derivatives are recognized in earnings each period. All amounts classified in earnings related to proprietary trading are 228Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) included in revenue on the Consolidated Statement of Operations. Cash inflows and outflows related to derivative instruments are includedas a component of operating, investing or financing cash flows in the Consolidated Statements of Cash Flows, depending on the nature ofeach transaction. For commodity derivative contracts, effective with the date of the merger with Constellation, Generation no longer utilizes the electionprovided for by the cash flow hedge designation and de-designated all of its existing cash flow hedges prior to the merger. Because theunderlying forecasted transactions remain probable, the fair value of the effective portion of these cash flow hedges was frozen inaccumulated OCI and will be reclassified to results of operations when the forecasted purchase or sale of the energy commodity occurs, orbecomes probable of not occurring. None of Constellation’s designated cash flow hedges for commodity transactions prior to the merger werere-designated as cash flow hedges. The effect of this decision is that all derivatives executed to hedge economic risk for commodities arerecorded at fair value with changes in fair value recognized through earnings for the combined company. As part of Generation’s energy marketing business, Generation enters into contracts to buy and sell energy to meet the requirementsof its customers. These contracts include short-term and long-term commitments to purchase and sell energy and energy-related products inthe energy markets with the intent and ability to deliver or take delivery of the underlying physical commodity. Normal purchases and normalsales are contracts where physical delivery is probable, quantities are expected to be used or sold in the normal course of business over areasonable period of time and will not be financially settled. Revenues and expenses on derivative contracts that qualify, and are designated,as normal purchases and normal sales are recognized when the underlying physical transaction is completed. While these contracts areconsidered derivative financial instruments, they are not required to be recorded at fair value, but rather are recorded on an accrual basis ofaccounting. See Note 12—Derivative Financial Instruments for additional information. Retirement Benefits (Exelon, Generation, ComEd, PECO and BGE) Exelon sponsors defined benefit pension plans and other postretirement benefit plans for essentially all Generation, ComEd, PECO,BGE and BSC employees. Effective March 12, 2012, Exelon became the sponsor of all of Constellation’s defined benefit pension and otherpostretirement benefit plans and defined contribution savings plans. The measurement of the plan obligations and costs of providing benefits under these plans involve various factors, including numerousassumptions and accounting elections. The assumptions are reviewed annually and at any interim remeasurement of the plan obligations.The impact of assumption changes or experience different from that assumed on pension and other postretirement benefit obligations isrecognized over time rather than immediately recognized in the income statement. Gains or losses in excess of the greater of ten percent ofthe projected benefit obligation or the MRV of plan assets are amortized over the expected average remaining service period of planparticipants. See Note 16—Retirement Benefits for additional discussion of Exelon’s accounting for retirement benefits. Equity Investment Earnings (Losses) of Unconsolidated Affiliates (Exelon and Generation) Exelon and Generation include equity in earnings from equity method investments in qualifying facilities, power projects and jointventures, including Generation’s 50.01% interest in CENG, in equity in earnings (losses) of unconsolidated affiliates. Equity in earnings(losses) of unconsolidated affiliates also includes any adjustments to amortize the difference, if any, except for goodwill and land, between 229Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

See Note 5—Investment in CENG and Note 25—Related Party Transactions for additional discussion of Exelon’s and Generation’s investment inCENG. Exelon and Generation continuously monitor for issues that potentially could impact future profitability of these equity methodinvestments and which could result in the recognition of an impairment loss if such investment experiences an other than temporary declinein value. New Accounting Pronouncements (Exelon, Generation, ComEd, PECO and BGE) Exelon has identified the following new accounting pronouncements that have been recently adopted or issued that may affect theRegistrants. Presentation of Items Reclassified out of Accumulated Other Comprehensive Income In February 2013, the FASB issued authoritative guidance requiring entities to present either in the notes or parenthetically on the faceof the financial statements, reclassifications from each component of accumulated other comprehensive income and the affected incomestatement line items. Entities only need to disclose the affected income statement line item for components reclassified to net income in theirentirety; otherwise, a cross-reference to the related note should be provided. This guidance was effective for the Registrants for periodsbeginning after December 15, 2012 and was required to be applied prospectively. As this guidance provides only disclosure requirements, theadoption of this standard did not impact the Registrants’ results of operations, cash flows or financial positions. See Note 21—Changes inAccumulated Other Comprehensive Income for the new disclosures. Disclosures About Offsetting Assets and Liabilities In December 2011 (and amended in January 2013), the FASB issued authoritative guidance requiring entities to disclose both grossand net information about recognized derivative instruments, including bifurcated embedded derivatives, repurchase and reverse repurchaseagreements, and securities borrowing or lending transactions that are offset on the balance sheet or subject to an enforceable master nettingarrangement or similar agreement, irrespective of whether they are offset on the balance sheet. The guidance was effective for theRegistrants for periods beginning on or after January 1, 2013 and was required to be applied retrospectively. This guidance is primarilyapplicable to certain derivative transactions for Exelon and Generation. As this guidance provides only disclosure requirements, the adoptionof this standard did not impact the Registrants’ results of operations, cash flows or financial positions. See Note 12—Derivative FinancialInstruments for the new disclosures. Inclusion of the Fed Funds Effective Swap Rate as a Benchmark Interest Rate for Hedge Accounting Purposes In July 2013, the FASB issued authoritative guidance permitting entities to designate the Fed Funds Effective Swap Rate as a U.S.benchmark interest rate for hedge accounting purposes. Prior to the issuance of this guidance, only interest rates on direct treasuryobligations of the U.S. government and the LIBOR swap rate were considered benchmark interest rates in the U.S. This guidance waseffective immediately and can be applied prospectively for qualifying new or redesignated hedging relationships entered into on or afterJuly 17, 2013. Currently, the Registrants do not use the Fed Funds Effective Swap Rate as a benchmark interest rate, but may in the future. 230Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The following recently issued accounting standard is not yet required to be reflected in the combined financial statements of theRegistrants. Presentation of Unrecognized Tax Benefits When Net Operating Loss Carryforwards, Similar Tax Losses or Tax CreditCarryforwards Exist In July 2013, the FASB issued authoritative guidance requiring entities to present unrecognized tax benefits as a reduction to deferredtax assets for losses or other tax carryforwards that would be available to offset the uncertain tax positions at the reporting date. Currently, theRegistrants present their unrecognized tax benefits as liabilities on a gross basis unless an unrecognized tax benefit is directly associatedwith a tax position taken in a tax year that results in the recognition of a net operating loss or other tax carryforward for that year. Thisguidance is effective for the Registrants for periods beginning after December 15, 2013 and is required to be applied prospectively, withretroactive application permitted. The Registrants will not retroactively adopt this guidance. This guidance is currently not expected to have animpact on the Registrants upon adoption with the exception of Exelon and Generation in which approximately $11 million of unrecognizedtax benefits will be offset against current deferred income assets. The adoption of this standard will not impact the Registrants’ results ofoperations. 2. Variable Interest Entities (Exelon, Generation, ComEd, PECO and BGE) Under the applicable authoritative guidance, a VIE is a legal entity that possesses any of the following characteristics: an insufficientamount of equity at risk to finance its activities, equity owners who do not have the power to direct the significant activities of the entity (orhave voting rights that are disproportionate to their ownership interest), or equity owners who do not have the obligation to absorb expectedlosses or the right to receive the expected residual returns of the entity. Companies are required to consolidate a VIE if they are its primarybeneficiary, which is the enterprise that has the power to direct the activities that most significantly impact the entity’s economic performance. At December 31, 2013 and 2012, the Exelon, Generation, and BGE consolidated four and five VIEs or VIE groups, respectively, forwhich the applicable Registrant was the primary beneficiary. As of December 31, 2013, the Registrants had one VIE for which theRegistrants were the primary beneficiary, however, the VIE is immaterial and was not included in the consolidated financial statements or inthe consolidated VIE table below. As of December 31, 2013 and 2012, the Registrants had significant interests in eight and nine other VIEsfor which the Registrants do not have the power to direct the entities’ activities, respectively, and accordingly, were not the primarybeneficiary. 231Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Consolidated Variable Interest Entities The carrying amounts and classification of the consolidated VIEs’ assets and liabilities included in the Registrants’ consolidatedfinancial statements at December 31, 2013 and 2012 are as follows: December 31, 2013 December 31, 2012 Exelon Generation BGE Exelon Generation BGE Current assets $484 $446 $28 $550 $519 $30 Noncurrent assets 1,905 1,884 3 1,719 1,680 — Total assets $2,389 $2,330 $31 $2,269 $2,199 $30 Current liabilities $566 $481 $74 $684 $612 $71 Noncurrent liabilities 774 562 195 775 470 265 Total liabilities $1,340 $1,043 $269 $1,459 $1,082 $336 (a)Includes certain purchase accounting adjustments not pushed down to the BGE standalone entity.(b)Includes total assets of $146 million and total liabilities of $42 million as of December 31, 2012 related to a retail supply company that is not a consolidated VIE as ofDecember 31, 2013. See additional information below. Except as specifically noted below, the assets in the table above are restricted for settlement of the VIE obligations and the liabilities inthe preceding table can only be settled using VIE resources. RSB BondCo LLC. In 2007, BGE formed RSB BondCo LLC (BondCo), a special purpose bankruptcy remote limited liabilitycompany, to acquire and hold rate stabilization property and to issue and service bonds secured by the rate stabilization property. In June2007, BondCo purchased rate stabilization property from BGE, including the right to assess, collect, and receive non-bypassable ratestabilization charges payable by all residential electric customers of BGE. These charges are being assessed in order to recover previouslyincurred power purchase costs that BGE deferred pursuant to Senate Bill 1. BGE has determined that BondCo is a VIE for which it is theprimary beneficiary. As a result, BGE consolidates BondCo. BondCo’s assets are restricted and can only be used to settle the obligations of BondCo. Further, BGE is required to remit all paymentsit receives from customers for rate stabilization charges to BondCo. During 2013, 2012, and 2011, BGE remitted $83 million, $85 million,and $92 million, respectively, to BondCo. BGE did not provide any additional financial support to BondCo during 2013. Further, BGE does not have any contractualcommitments or obligations to provide additional financial support to BondCo unless additional rate stabilization bonds are issued. TheBondCo creditors do not have any recourse to the general credit of BGE in the event the rate stabilization charges are not sufficient to coverthe bond principal and interest payments of BondCo. Retail Gas Group. During 2009, Constellation formed two new entities, which now are part of Generation, and combined them withits existing retail gas activities into a retail gas entity group for the purpose of entering into a collateralized gas supply agreement with a third-party gas supplier. While Generation owns 100% of these entities, it has been determined that the retail gas entity group is a VIE becausethere is not sufficient equity to fund the group’s activities without the additional credit support that is provided in the form of a parentalguarantee. Generation is the primary beneficiary of the retail gas entity group; accordingly, Generation consolidates the retail gas entity groupas a VIE. 232(a)(a)(b) (b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The third-party gas supply arrangement is collateralized as follows: • The assets of the retail gas entity group must be used to settle obligations under the third-party gas supply agreement before it canmake any distributions to Generation, • The third-party gas supplier has a collateral interest in all of the assets and equity of the retail gas entity group, and • As of December 31, 2013 Exelon provided a $75 million parental guarantee to the third-party gas supplier in support of the retailgas entity group. Other than credit support provided by the parental guarantee, Exelon or Generation do not have any contractual or other obligations toprovide additional financial support under the collateralized third-party gas supply agreement. The third-party gas supply creditors do not haveany recourse to Exelon’s or Generation’s general credit other than the parental guarantee. Solar Project Entity Group. In 2011, Constellation formed a group of solar project limited liability companies to build, own, andoperate solar power facilities, which are now part of Generation. Additionally, on September 30, 2011, Generation acquired all of the equityinterests in Antelope Valley Solar Ranch One (Antelope Valley) from First Solar, Inc., a 230-MW solar PV project under construction innorthern Los Angeles County, California. While Generation owns 100% of these entities, it has been determined that certain of the individualsolar project 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 pricevariability from the entities through the fixed price power and/or REC purchase agreements. Generation is the primary beneficiary of thesolar project entities that qualify as VIEs because Generation controls the design, construction, and operation of the solar power facilities.Generation provides capital funding to these solar VIE entities for ongoing construction of the solar power facilities. In addition, these solarVIE entities have an aggregate amount of outstanding debt with third parties of $536 million, as of December 31, 2013, for which thecreditors have no recourse to Generation, however there is limited recourse to Generation with respect to remaining equity contributionsnecessary to complete the Antelope Valley project. For additional information on these project-specific financing arrangements refer to Note 13—Debt and Credit Agreements. Retail Power Supply Entity. In August 2013, Generation executed an agreement to terminate its energy supply contract with a retailpower supply company that was previously a consolidated VIE. Generation did not have an ownership interest in the entity, but was theprimary beneficiary through the energy supply contract. As a result of the termination, Generation no longer has a variable interest in theretail power supply company and ceased consolidation of the entity during the third quarter of 2013. Upon deconsolidation, there was no gainor loss recognized. The assets, liabilities, and non-controlling interest were removed from Exelon’s and Generation’s balance sheet and thechange in non-controlling interest is also reflected on the Statement of Changes in Shareholders’ Equity and the Statement of Changes inMember’s Equity for Exelon and Generation, respectively. Wind Project Entity Group. Generation owns and operates a number of wind project limited liability entities, the majority of whichwere acquired on December 9, 2010 when Generation completed the acquisition of all of the equity interests of John Deere Renewables,LLC (now known as Exelon Wind). Generation has evaluated the significant agreements and ownership structures and risks of each of itswind projects and underlying entities, and determined that certain of the entities are VIEs because either the projects have non-controllinginterest holders that absorb variability from the wind projects, or the customers absorb price variability from the entities through the fixed pricepower and/or REC purchase agreements. Generation is the primary beneficiary of the wind project entities that 233Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) qualify as VIEs because Generation controls the design, construction, and operation of the wind power facilities. While Generation owns100% of the majority of the wind project entities, 10 of the projects have non-controlling equity interests held by third parties, that currentlyrange between 1% and 6%. Of these 10 projects, Generation’s current economic interests in nine of the projects are significantly greater thanits stated contractual governance rights and all of these projects have reversionary interest provisions that provide the non-controlling interestholder with a purchase option, certain of which are considered bargain purchase prices, which, if exercised, transfers ownership of theprojects to the non-controlling interest holder upon either the passage of time or the achievement of targeted financial returns. The ownershipagreements with the non-controlling interests state that Generation is to provide financial support to the projects in proportion to its currenteconomic interests in the projects that currently range between 94% and 99%. However, no additional support to these projects beyond whatwas contractually required has been provided during 2013. As of December 31, 2013, the carrying amount of the assets and liabilities thatare consolidated as a result of Generation being the primary beneficiary of the wind VIE entities primarily relate to the wind generatingassets, PPA intangible assets and working capital amounts. As of December 31, 2013 and 2012, ComEd and PECO did not have any consolidated VIEs. Unconsolidated Variable Interest Entities Exelon’s and Generation’s variable interests in unconsolidated VIEs generally include three transaction types: (1) equity investments,(2) energy purchase and sale contracts, and (3) fuel purchase commitments. For the equity investments, the carrying amount of theinvestments is reflected on their Consolidated Balance Sheets in Investments in affiliates. For the energy purchase and sale contracts andthe fuel purchase commitments (commercial agreements), the carrying amount of assets and liabilities in Exelon’s and Generation’sConsolidated Balance Sheets that relate to their involvement with the VIEs are predominately related to working capital accounts andgenerally represent the amounts owed by, or owed to, Exelon and Generation for the deliveries associated with the current billing cyclesunder the commercial agreements. Further, Exelon and Generation have not provided material debt or equity support, liquidity arrangementsor performance guarantees associated with these commercial agreements. As of December 31, 2013 and 2012, Exelon and Generation had significant unconsolidated variable interests in eight and nine,respectively, VIEs for which they were not the primary beneficiary; including certain equity investments and certain commercial agreements.The change in the number of unconsolidated variable interests is driven by the completion of certain obligations which cause the entities tono longer be unconsolidated variable interests offset by the addition of an equity investment in a residential solar provider.

These items are included toprovide information regarding the relative size of the unconsolidated VIEs.(b)These items represent amounts on Exelon’s and Generation’s Consolidated Balance Sheets related to the asset sale agreement with ZionSolutions, LLC. The netassets pledged for Zion Station decommissioning includes gross pledged assets of $458 million and $614 million as of December 31, 2013 and December 31, 2012,respectively; offset by payables to ZionSolutions LLC of $414 million and $564 million as of December 31, 2013 and December 31, 2012, respectively. These items areincluded to provide information regarding the relative size of the ZionSolutions LLC unconsolidated VIE. See Note 15—Asset Retirement Obligations for furtherdiscussion. For each unconsolidated VIE, Exelon and Generation assess 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. In addition,there are no agreements with, or commitments by, third parties that would materially affect the fair value or risk of their variable interests inthese variable interest entities. Energy Purchase and Sale Agreements. In March 2005, Constellation, to which Generation is now a successor, closed atransaction in which Generation assumed from a counterparty two power sales contracts with previously existing VIEs. The VIEs previouslywere created by the counterparty to issue debt in order to monetize the value of the original contracts to purchase and sell power. Under thepower sales contracts, Generation sold power to the VIEs which, in turn, sold that power to an electric distribution utility through 2013. Inconnection with this transaction, a third-party acquired the equity of the VIEs and Generation loaned that party a portion of the purchase price.If the electric distribution utility were to default under its obligation to buy power from the VIEs, the equity holder could transfer its equityinterests to Generation in lieu of repaying the loan. In this event, Generation would have the right to seek recovery of its losses from theelectric distribution utility. As a result, Generation has concluded that consolidation was not required. During 2013, the third-party repaid theirobligations of the loan with Generation which caused the entities to no longer be unconsolidated VIEs. ZionSolutions. Generation has an asset sale agreement with EnergySolutions, Inc. and certain of its subsidiaries, includingZionSolutions, LLC (ZionSolutions), which is further discussed in Note 15—Asset Retirement Obligations. Under this agreement,ZionSolutions can put the assets and liabilities back to Generation when decommissioning is complete. Generation has evaluated thisagreement and determined that, through the put option, it has a variable interest in ZionSolutions but is not the primary beneficiary. As aresult, Generation has concluded that consolidation is not required. Other than the asset sale agreement, Exelon or Generation do not haveany contractual or other obligations to provide additional financial support and ZionSolutions’ creditors do not have any recourse to Exelon’sor Generation’s general credit. 235(a)(a)(a)(a)(b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Fuel Purchase Commitments. Generation’s customer supply operations include the physical delivery and marketing of powerobtained through its generating capacity, and long-, intermediate- and short-term contracts. Generation also has contracts to purchase fuelsupplies for nuclear and fossil generation. These contracts and Generation’s membership in NEIL are discussed in further detail in Note 22—Commitments and Contingencies. Generation has evaluated these contracts and its membership with NEIL and determined that it eitherhas no variable interest in an entity or, where Generation does have a variable interest in an entity, the variable interest is not significant andit is not the primary beneficiary; therefore, consolidation is not required. For contracts where Generation has a variable interest, the level of variability being absorbed through the contracts is not consideredsignificant because of the small proportion of the entities’ activities encompassed by the contracts with Generation. Further, Generation hasconsidered which interest holder has the power to direct the activities that most significantly affect the economic performance of the VIE andthus is considered the primary beneficiary and is required to consolidate the entity. The primary beneficiary must also have exposure tosignificant losses or the right to receive significant benefits from the VIE. In general, the most significant activity of the VIEs is the operationand maintenance of the facilities. Facilities represent power plants, sources of uranium and fossil fuels, or plants used in the uraniumconversion, enrichment and fabrication process. Generation does not have control over the operation and maintenance of the facilitiesconsidered VIEs, and it does not bear operational risk of the facilities. Furthermore, Generation has no debt or equity investments in theentities and Generation does not provide any other financial support through liquidity arrangements, guarantees or other commitments otherthan purchase commitments described in Note 22—Commitments and Contingencies. Upon consideration of these factors, Generationdoes not consider itself to have significant variable interests in these entities or be the primary beneficiary of these VIEs and, accordingly, hasdetermined that consolidation is not required. Investment in Energy Development Projects. Generation has several equity investments in energy generating facilities.Generation has evaluated the significant agreements, ownership structures and risks of each of its equity investments, and determined thatcertain of the entities are VIEs because Generation guarantees the debt of the entity, provides equity support, or provides operating services tothe entity. Generation has reviewed the entities and has determined that Generation is not the primary beneficiary of the entities that qualifyas VIEs because Generation does not have the power to direct the activities of the VIEs that most significantly impact the VIEs economicperformance. Residential Solar Provider. Generation has an equity investment in a residential solar provider. Generation has evaluated thesignificant agreements, ownership structure and risks of the entity, and determined that the entity is a VIE because it does not have sufficientequity at risk to fund its operations. Generation has determined that its equity investment in the entity is a variable interest. However,Generation has concluded that we are not the primary beneficiary because Generation does not have the power to direct the activities of theVIE that most significantly impact the entity’s economic performance. Exelon or Generation do not have any contractual or other obligationsto provide additional financial support and the residential solar provider’s creditors do not have any recourse to Exelon’s or Generation’sgeneral credit. ComEd, PECO and BGE ComEd’s, PECO’s, and BGE’s retail operations frequently include the purchase of electricity and RECs through procurement contractsof varying durations. See Note 3—Regulatory Matters and Note 22—Commitments and Contingencies for additional information on thesecontracts. ComEd, PECO 236Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) and BGE have evaluated these types of contracts and have historically determined that either there is no significant variable interest in theentity, or where either ComEd, PECO or BGE does have a significant variable interest in a VIE, ComEd, PECO or BGE would not be theprimary beneficiary and, therefore, consolidation would not be required. For contracts where ComEd, PECO or BGE is considered to have a significant variable interest, consideration is given to whichinterest holder has the power to direct the activities that most significantly affect the economic performance of the VIE. In general, the mostsignificant activity of the VIEs is the operation and maintenance of their production or procurement processes related to electricity, RECs,AECs or natural gas. ComEd, PECO and BGE do not have control over the operation and maintenance of the entities and they do not bearoperational risk related to the associated activities. Generally, the carrying amounts of assets and liabilities in ComEd’s, PECO’s, andBGE’s Consolidated Balance Sheets that relate to their involvement with VIEs as a result of commercial arrangements represent theamounts owed by the utilities for the purchases associated with the current billing cycles under the contracts. As of December 31, 2013, thetotal amount of accounts payable owed by the utilities under agreements with these VIEs was not material. In addition, variability from thesecontracts is mitigated by the fact that the utilities are able to recover costs incurred under purchase agreements through customer rates.Furthermore, ComEd, PECO and BGE do not have any debt or equity investments in these VIEs and do not provide any other financialsupport through liquidity arrangements, guarantees or other commitments other than purchase commitments described in Note 22—Commitments and Contingencies. Accordingly, none of ComEd, PECO or BGE considers itself to be the primary beneficiary of any VIEsas a result of commercial arrangements. The financing trust of ComEd, ComEd Financing III, the financing trusts of PECO, PECO Trust III and PECO Trust IV, and thefinancing trust of BGE, BGE Capital Trust II are not consolidated in Exelon’s, ComEd’s, PECO’s or BGE’s financial statements. Thesefinancing trusts were created to issue mandatorily redeemable trust preferred securities. ComEd, PECO, and BGE have concluded that theydo not have a significant variable interest in ComEd Financing III, PECO Trust III, PECO Trust IV or BGE Capital Trust II as each Registrantfinanced its equity interest in the financing trusts through the issuance of subordinated debt and, therefore, has no equity at risk. See Note 13—Debt and Credit Agreements for additional information. 3. Regulatory Matters (Exelon, Generation, ComEd, PECO and BGE) The following matters below discuss the current status of material regulatory and legislative proceedings of the Registrants. Illinois Regulatory Matters Energy Infrastructure Modernization Act (Exelon and ComEd). Background Since 2011, ComEd’s distribution rates are established through a performance-based rate formula, pursuant to EIMA. EIMA alsoprovides a structure for substantial capital investment by utilities over a ten-year period to modernize Illinois’ electric utility infrastructure.Participating utilities are required to file an annual update to the performance-based formula rate tariff on or before May 1, with resulting rateseffective in January of the following year. This annual formula rate update is based on prior year actual costs and current year projected capitaladditions. The update also reconciles any differences between the revenue requirement(s) in effect for the prior year and actual costs incurredfor that year. Throughout each year, ComEd records regulatory assets or regulatory liabilities and 237Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely. The user assumes all risks for any damages or losses arising from any use of this information,except to the extent such damages or losses cannot be limited or excluded by applicable law. Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) corresponding increases or decreases to operating revenues for any differences between the revenue requirement(s) in effect and ComEd’sbest estimate of the revenue requirement expected to be approved by the ICC for that year’s reconciliation. As of December 31, 2013, andDecember 31, 2012, ComEd had a net regulatory asset associated with the distribution formula rate of $463 million and $209 million,respectively. Formula Rate Tariff On November 8, 2011, ComEd filed its initial formula rate tariff and associated testimony based on 2010 costs and 2011 plant additions.The primary purpose of that proceeding was to establish the formula rate under which rates will be calculated going-forward, and the initialrates, which went into effect in late June 2012. On May 29, 2012, the ICC issued an Order (May Order) in that proceeding. The May Orderreduced the annual revenue requirement by $168 million, or approximately $110 million more than the proposed reduction by ComEd. Ofthis incremental revenue requirement reduction, approximately $50 million reflected the ICC’s determination that certain costs should berecovered through alternative rate recovery tariffs available to ComEd or will be reflected in a subsequent annual reconciliation, therebyprimarily delaying the timing of cash flows. The incremental revenue reduction also reflected a $35 million reduction for the disallowance ofreturn on ComEd’s pension asset, a $10 million reduction for incentive compensation related adjustments, and $15 million of reductions forvarious adjustments for cash working capital, operating reserves, and other technical items. In the second quarter of 2012, ComEd recordeda decrease in revenue of approximately $100 million pre-tax to decrease the regulatory asset for 2011 and for the first three months of 2012consistent with the terms of the May Order. On June 22, 2012, the ICC granted an expedited rehearing on three of the issues decided in the May Order. On October 3, 2012, theICC issued its final order (Rehearing Order) in that rehearing, adopting ComEd’s position on the return on its pension asset, resulting in anincrease in the annual revenue requirement. For the two other issues, the ICC ruled against ComEd by reaffirming use of an average ratherthan year-end rate base in the annual reconciliation and amending its prior order to provide a short-term debt rate to apply to the annualreconciliation. In the fourth quarter of 2012, ComEd recorded an increase in revenue of approximately $135 million pre-tax consistent withthe terms of the Rehearing Order, of which $75 million pre-tax reflects the reinstatement of the return on pension asset for 2011 and $60million pre-tax reflects the return on pension asset for 2012. New rates reflecting the impacts of the Rehearing Order went into effect inNovember 2012. ComEd has filed an appeal with the Illinois Appellate Court. ComEd cannot predict the results of any such appeals. In March 2013, the Illinois legislature passed Senate Bill 9 to clarify the intent of EIMA on the three issues decided in the RehearingOrder: an allowed return on ComEd’s pension asset; the use of year-end rather than average rate base and capital structure in the annualreconciliation; and the use of ComEd’s weighted average cost of capital interest rate rather than a short-term debt rate to apply to the annualreconciliation. On May 22, 2013, Senate Bill 9 became effective after the Illinois legislature overrode the Governor’s veto of that Bill. OnJune 5, 2013, the ICC approved ComEd’s updated distribution formula rate structure to reflect the impacts of Senate Bill 9. In October 2013, the ICC opened an investigation (the Investigation), in response to a complaint filed by the Illinois Attorney General, tochange the formula rate structure by requesting three changes: the elimination of the income tax gross-up on the weighted average cost ofcapital used to calculate interest on the annual reconciliation balance, the netting of associated accumulated deferred income taxes against theannual reconciliation balance in calculating interest, and the use of average rather than year-end rate base for determining any ROE collaradjustment. On November 26, 2013, the ICC 238Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) issued its final order in the Investigation, rejecting two of the proposed changes but accepting the proposed change to eliminate the incometax gross-up on the weighted average cost of capital used to calculate interest on the annual reconciliation balance. The accepted changebecame effective in January 2014, and is estimated to reduce ComEd’s 2014 revenue by approximately $8 million. This change had nofinancial statement impact on ComEd in 2013. ComEd and intervenors requested rehearing, however all rehearing requests were denied bythe ICC. ComEd and intervenors have filed appeals with the Illinois Appellate Court. ComEd cannot predict the results of any such appeals. Annual Reconciliation 2012 Filing. On April 30, 2012, ComEd filed its annual distribution formula rate. On December 20, 2012, the ICC, issued its finalorder, which increased the revenue requirement by $73 million, in conformity with the formula rate structure provided in the May 2012 andRehearing Orders. The $73 million reflected an increase of $80 million for the initial revenue requirement for 2012 and a decrease of $7million for the annual reconciliation for 2011. The rate increase was set using an allowed return on capital of 7.54% (inclusive of an allowedreturn on common equity of 9.81%). The rates took effect in January 2013. ComEd and intervenors requested a rehearing on specific issues,which was denied by the ICC. ComEd and intervenors also filed appeals with the Illinois Appellate Court. ComEd cannot predict the resultsof any such appeals. On May 30, 2013, ComEd updated its revenue requirement allowed in the December 2012 Order to reflect the impacts of Senate Bill9, which resulted in a reduction to the current revenue requirement in effect of $14 million. The rates took effect in July 2013. 2013 Filing. On April 29, 2013, ComEd filed its annual distribution formula rate, which was updated in August 2013, to request a totalincrease to the revenue requirement of $353 million of which approximately $42 million related to Senate Bill 9. On December 19, 2013,the ICC issued its final order which increased the revenue requirement by $341 million, reflecting an increase of $160 million for the initialrevenue requirement for 2013 and an increase of $181 million for the annual reconciliation for 2012. The rate increase was set using anallowed return on capital of 6.94% (inclusive of an allowed return on common equity of 8.72%). The rates took effect in January 2014.ComEd requested a rehearing on specific issues, which was denied by the ICC. ComEd also filed an appeal. ComEd cannot predict theresults of any such appeals. Expenditures and Capital Investment As part of the enactment of EIMA legislation ComEd made an initial contribution of $15 million (recognized as expense in 2011) to anew Science and Technology Innovation Trust fund on July 31, 2012, and will make recurring annual contributions of $4 million, the first ofwhich was made on December 31, 2012, which will be used for customer education for as long as the AMI Deployment Plan remains ineffect. In addition, ComEd will contribute $10 million per year for five years, as long as ComEd is subject to EIMA, to fund customerassistance programs for low-income customers, which will not be recoverable through rates. These contributions began in 2012. On January 6, 2012, ComEd filed its Infrastructure Investment Plan with the ICC. Under that plan, ComEd will invest approximately$2.6 billion over ten years to modernize and storm-harden its distribution system and to implement smart grid technology. On April 23,2012, ComEd filed its initial AMI Deployment Plan with the ICC, which was approved by the ICC on June 22, 2012, with certainmodifications. ComEd outlined the new deployment schedule within testimony provided in the AMI Plan Rehearing and filed a revised AMIdeployment plan. The deployment plan provides for the installation of 4 million electric smart meters, of which more than 60,000 meterswere installed by the end of 2013. 239Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Appeal of 2007 Illinois Electric Distribution Rate Case (Exelon and ComEd). The ICC issued an order in ComEd’s 2007 electricdistribution rate case (2007 Rate Case) approving a $274 million increase in ComEd’s annual delivery services revenue requirement, whichbecame effective in September 2008. In the order, the ICC authorized a 10.3% rate of return on common equity. ComEd and several otherparties filed appeals of the rate order with the Illinois Appellate Court (Court). The Court issued a decision on September 30, 2010, rulingagainst ComEd on the treatment of post-test year accumulated depreciation and the recovery of system modernization costs via a rider (RiderSMP). The court held the ICC abused its discretion in not reducing ComEd’s rate base to account for an additional 18 months of accumulateddepreciation while including post-test year pro forma plant additions through that period. ComEd continued to bill rates as established underthe ICC’s order in the 2007 Rate Case until June 1, 2011 when the rates set in the 2010 electric distribution rate case (2010 Rate Case)became effective. In subsequent ICC proceedings, the ICC issued an order requiring ComEd to provide a refund of approximately $37million to customers related to the treatment of post-test year accumulated depreciation issue. On March 26, 2012, ComEd filed a notice ofappeal with the Court. However, on September 27, 2013 the Court ruled against ComEd on the accumulated depreciation issue and affirmed that ComEdowes a refund to customers of $37 million. As of December 31, 2013, and December 31, 2012, ComEd was fully reserved for this liability.ComEd will not seek rehearing or appeal on this matter and is working with the ICC on the process and timing for a refund to customers. Advanced Metering Program Proceeding (Exelon and ComEd) ComEd’s 2007 Rate Case filing included a system modernizationrider, which permitted investments in AMI to study the costs and benefits and to develop the cost estimate of full system-wideimplementation. In October 2009, the ICC approved a modified version of ComEd’s system modernization rider proposed in the 2007 RateCase, Rider AMP (Advanced Metering Program). ComEd collected approximately $24 million under Rider AMP through December 31,2013. Several other parties, including the Illinois Attorney General, appealed the ICC’s order on Rider AMP. In ComEd’s 2010 electricdistribution rate case, the ICC approved ComEd’s transfer of other costs from recovery under Rider AMP to recovery through electricdistribution rates. On March 19, 2012, the Court reversed the ICC’s approval of Rider AMP, concluding that the ICC’s October 2009 approvalof the rider constituted single-issue ratemaking. ComEd filed a Petition for Leave to Appeal to the Illinois Supreme Court on April 23, 2012,which was denied in September 2012, and the matter was returned to the ICC to calculate a refund amount. ComEd believes any refundobligation associated with Rider AMP should be prospective from no earlier than the date of the Appellate Court’s order on March 19, 2012.As a result, ComEd recorded a regulatory liability of approximately $0.4 million at December 31, 2013, which represents the amountscollected from customers since March 19, 2012. ComEd cannot predict the ultimate outcome of the ICC proceeding and therefore, actualrefunds may differ from the estimated accrual recorded at December 31, 2013. 2010 Illinois Electric Distribution Rate Case (Exelon and ComEd). On May 24, 2011, the ICC issued an order in ComEd’s 2010Rate Case, which became effective on June 1, 2011. The order approved a $143 million increase to ComEd’s annual delivery servicesrevenue requirement and a 10.5% rate of return on common equity. ComEd originally requested a $396 million increase, although it wassubsequently reduced to $343 million to account for various adjustments. As expected, the ICC followed the Court’s ruling on ComEd’s2007 Rate Case on the post-test year accumulated depreciation issue. The order allowed ComEd to establish or reestablish a net amount ofapproximately 240Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) $40 million of previously expensed plant balances or new regulatory assets, which is reflected as a reduction in operating and maintenanceexpense and income tax expense in 2011. The order also affirmed the current regulatory asset for severance costs, which was challenged byan intervener in the 2010 Rate Case. The order was appealed to the Court by several parties on a number of issues. On May 16, 2013, theCourt dismissed as moot the appeals of the ICC’s order in the 2010 Rate Case as ComEd now recovers distribution costs under EIMAthrough a pre-established formula rate tariff. Utility Consolidated Billing and Purchase of Receivables (Exelon and ComEd). Since the first quarter of 2011, ComEd has beenrequired to buy certain RES receivables, primarily residential and small commercial and industrial customers, at the option of the RES, forelectric supply service and then include those amounts on ComEd’s bill to customers. Receivables are purchased at a discount tocompensate ComEd for uncollectible accounts. ComEd produces consolidated bills for the aforementioned retail customers reflecting chargesfor electric delivery service and purchased receivables. As of December 31, 2013, the balance of purchased accounts receivable was $105million. Under the applicable tariff, ComEd recovers from RES and customers the costs for implementing and operating the program. Anumber of municipalities, including the City of Chicago have switched to RES electric supply. As a result, ComEd experienced a significantincrease in the amount of RES receivables it purchased in 2013. Illinois Procurement Proceedings (Exelon, Generation and ComEd). ComEd is permitted to recover its electricity procurementcosts from retail customers without mark-up. Since June 2009, as a result of the Illinois Settlement Legislation, the IPA designs, and theICC approves, an electricity supply portfolio for ComEd and the IPA administers a competitive process under which ComEd procures itselectricity supply from various suppliers, including Generation. On December 21, 2011, the ICC approved the IPA’s procurement plancovering the period June 2012 through May 2017. The Illinois Settlement Legislation requires ComEd to purchase an increasing percentage of the electricity it purchases for customerdeliveries from renewable energy resources. Purchases by customers of electricity from competitive generation suppliers, whether as aresult of the customers’ own actions or as a result of municipal aggregation, are not included in this calculation and have the effect ofreducing ComEd’s purchase obligation. ComEd entered into several 20-year contracts with unaffiliated suppliers in December 2010regarding the procurement of long-term renewable energy and associated RECs in order to meet its obligations under the state’s RPS. Underthe Illinois Settlement Legislation, all associated costs are recoverable from customers. As a result of reduced ComEd load forecasts, purchases under the existing long-term contracts for energy and the associated RECswere reduced on a pro-rata basis under the terms of those contracts for the June 2013—May 2014 period to keep the purchases under thestatutory rate impact cap. The curtailment’s impact on ComEd’s financial position and cash flows was immaterial. On December 18, 2013, the ICC approved the IPA’s 2014-2019 procurement plan. The plan provides for two separate energyprocurements during 2014 to address potential fluctuations in energy demand due to customer switching between ComEd and competitiveelectric generation suppliers. The Commission also approved the IPA’s expansion of energy efficiency programs for both ComEd andAmeren. The ICC did not require the acquisition of additional renewable resources in 2014-2015 due to insufficient available funds to procurethose resources. Further, the ICC again approved a reduction of purchases under the existing long-term contracts for energy and theassociated RECs on a pro-rata basis under the terms of those contracts for the June 2014—May 2015 period to keep the purchases under thestatutory rate impact cap; however the amount of the reduction will not be finalized and approved by the ICC until March 2014.

See Note 12—Derivative Financial Instruments for additional information regarding ComEd’sfinancial swap contract with Generation, which expired in May 2013, and long-term renewable energy contracts. During 2013, the ICC approved, and directed ComEd and Ameren (the Utilities) to enter into 20-year sourcing agreements withFutureGen Industrial Alliance, Inc (FutureGen), under which FutureGen will retrofit and repower an existing plant in Morgan County, Illinoisto a 166 MW near zero emissions coal-fueled generation plant, with an assumed commercial operation date in 2017. The sourcingagreement provides that the Utilities will pay FutureGen’s contract prices, which are set annually pursuant to a formula rate. The contractprices are based on the difference between the costs of the facility and the revenues FutureGen receives from selling capacity and energyfrom the unit into the MISO or other markets, as well as any other revenue FutureGen receives from the operation of the facility. The orderalso directs the Utilities to recover (or pass along) these costs from the Utilities’ distribution system customers, regardless of whether theypurchase electricity from the utility or from competitive electric generation suppliers. In February 2013, ComEd filed an appeal with theIllinois Appellate Court questioning the legality of requiring ComEd to procure power for retail customers purchasing electricity fromcompetitive electric generation suppliers. On August 22, 2013, the Utilities executed the sourcing agreement with FutureGen in accordance with the ICC order. However, in theevent the order is reversed as a result of the appeal, ComEd’s obligations under the sourcing agreement should be suspended. Dependingon the ultimate outcome of the appeals, the eventual market conditions and the cost of the facility, the sourcing agreement could have amaterial adverse impact on Exelon’s and ComEd’s cash flows and financial positions. See Note 22—Commitments and Contingencies for additional information on ComEd’s energy commitments. Energy Efficiency and Renewable Energy Resources (Exelon and ComEd). As a result of the Illinois Settlement Legislation,electric utilities in Illinois are required to include cost-effective energy efficiency resources in their plans to meet an incremental annualprogram energy savings requirement of 0.2% of energy delivered to retail customers for the year ended June 1, 2009, which increasesannually to 2.0% of energy delivered in the year commencing June 1, 2015 and each year thereafter. Additionally, during the ten-year periodthat began June 1, 2008, electric utilities must implement cost-effective demand response measures to reduce peak demand by 0.1% overthe prior year for eligible retail customers. The energy efficiency and demand response goals are subject to rate impact caps each year.Utilities are allowed recovery of costs for energy efficiency and demand response programs, subject to approval by the ICC. In December2010, the ICC approved ComEd’s second three-year Energy Efficiency and Demand Response Plan covering the period June 2011 throughMay 2014. The plans are designed to meet the Illinois Settlement Legislation’s energy efficiency and demand response goals through May2014, including reductions in delivered energy to all retail customers and in the peak demand of eligible retail customers. EIMA provides for additional energy efficiency in Illinois. Starting in the June 2013—May 2014 period and occurring annually thereafter,as part of the IPA procurement plan, ComEd is to include cost-effective expansion of current energy efficiency programs, and additional newcost-effective program and/or third-party energy efficiency programs that are identified through a request for proposal process. All cost-effectiveenergy efficiency programs are included in the IPA procurement plan for consideration of implementation. While these programs aremonitored separately from the Energy Efficiency Portfolio Standard (EEPS), funds for both the EEPS portfolio and IPA energy efficiencyprograms are collected under the same rider. 242Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Since June 1, 2008, utilities have been required to procure cost-effective renewable energy resources in amounts that equal or exceed2% of the total electricity that each electric utility supplies to its eligible retail customers. ComEd is also required to acquire amounts ofrenewable energy resources that will cumulatively increase this percentage to at least 10% by June 1, 2015, with an ultimate target of at least25% by June 1, 2025. All goals are subject to rate impact criteria set forth in the Illinois Settlement Legislation. As of December 31, 2013,ComEd had purchased sufficient renewable energy resources or equivalents, such as RECs, to comply with the Illinois SettlementLegislation. ComEd currently retires all RECs upon transfer and acceptance. ComEd is permitted to recover procurement costs of RECsfrom retail customers without mark-up through rates.

Pennsylvania Regulatory Matters 2010 Pennsylvania Electric and Natural Gas Distribution Rate Cases (Exelon and PECO). On December 16, 2010, thePAPUC approved the settlement of PECO’s electric and natural gas distribution rate cases, which were filed in March 2010, providingincreases in annual service revenue of $225 million and $20 million, respectively. The electric settlement provides for recovery of PJMtransmission service costs on a full and current basis through a rider. The approved electric and natural gas distribution rates becameeffective on January 1, 2011. In addition, the settlements included a stipulation regarding how tax benefits related to the application of any new IRS guidance onrepairs deduction methodology are to be handled from a rate-making perspective. The settlements require that the expected cash benefit fromthe application of any new guidance to tax years prior to 2011 be refunded to customers over a seven-year period. On August 19, 2011, theIRS issued Revenue Procedure 2011-43 providing a safe harbor method of tax accounting for electric transmission and distribution property.PECO adopted the safe harbor and elected a method change for the 2010 tax year. The expected total refund to customers for the tax cashbenefit from the application of the safe harbor to costs incurred prior to 2010 is $171 million. On October 4, 2011, PECO filed a supplementto its electric distribution tariff to execute the refund to customers of the tax cash benefit related to the IRC Section 481(a) “catch-up”adjustment claimed on the 2010 income tax return, which is subject to adjustment based on the outcome of IRS examinations. Credits havebeen reflected in customer bills since January 1, 2012. In September 2012, PECO filed an application with the IRS to change its method of accounting for gas distribution repairs for the 2011tax year. The expected total refund to customers for the tax cash benefit from the application of the new method to costs incurred prior to 2011is $54 million. This amount is subject to adjustment based on the outcome of IRS examinations. Credits have been reflected in customerbills since January 1, 2013. PECO currently anticipates that the IRS will issue guidance in early 2014 providing a safe harbor method ofaccounting for gas transmission and distribution property. The prospective tax benefits claimed as a result of the new methodology will be reflected in tax expense in the year in which they areclaimed on the tax return and will be reflected in the determination of revenue requirements in the next electric and natural gas distributionrate cases. See Note 14 for additional information. The 2010 electric and natural gas distribution rate case settlements did not specify the rate of return upon which the settlement rates arebased, but rather provided for an increase in annual revenue. PECO has not filed a transmission rate case since rates have been unbundled. 243Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Pennsylvania Procurement Proceedings (Exelon and PECO). PECO’s first PAPUC approved DSP Program, under whichPECO was providing default electric service, had a 29-month term that ended May 31, 2013. On October 12, 2012, the PAPUC issued itsOpinion and Order approving PECO’s second DSP Program, which was filed with the PAPUC in January 2012. The program, which has a24-month term from June 1, 2013 through May 31, 2015, complies with electric generation procurement guidelines set forth in Act 129.Under the DSP Programs, PECO is permitted to recover its electric procurement costs from retail default service customers without mark-upthrough the GSA. The GSA provides for the recovery of energy, capacity, ancillary costs and administrative costs and is subject toadjustments at least quarterly for any over or under collections. In addition, PECO’s second DSP Program provides for the recovery of AEPScompliance costs through the GSA rather than a separate AEPS rider. In the second DSP Program, PECO is procuring electric supply for its default electric customers through five competitive procurements.The load for the residential and small and medium commercial classes is served through competitively procured fixed price, fullrequirements contracts of two years or less. For the large commercial and industrial class load, PECO has competitively procured contractsfor full requirements default electric generation with the price for energy in each contract set to be the hourly price of the spot market duringthe term of delivery. In December 2012 and February 2013, PECO entered into contracts with PAPUC-approved bidders, includingGeneration, for its residential and small and medium commercial classes that began in June 2013. In September 2013, PECO entered intocontracts with PAPUC-approved bidders, including Generation, for its residential and small and medium commercial classes that began inDecember 2013. In January 2014, PECO entered into contracts with PAPUC-approved bidders, including Generation, for its residential andsmall, medium, and large commercial classes that will begin in June 2014. Charges incurred for electric supply procured through contractswith Generation are included in purchased power from affiliates on PECO’s Statement of Operations and Comprehensive Income. In addition, the second DSP Program includes a number of retail market enhancements recommended by the PAPUC in its previouslyissued Retail Markets Intermediate Work Plan Order. PECO was also directed to allow its low-income Customer Assistance Program (CAP)customers to purchase their generation supply from electric generation suppliers beginning April 1, 2014. On May 1, 2013, PECO filed aPetition for Approval of its CAP Shopping Plan with the PAPUC, which the PAPUC granted and denied in part on January 9, 2014. PECOand other parties to the proceeding filed petitions for reconsideration of the Commission’s decision on February 10, 2014, and these petitionsare currently pending before the PAPUC. Smart Meter and Smart Grid Investments (Exelon and PECO). Pursuant to Act 129 and the follow-on Implementation Order of2009, in April 2010, the PAPUC approved PECO’s Smart Meter Procurement and Installation Plan (SMPIP), under which PECO will installmore than 1.6 million smart meters and an AMI communication network by 2020. The first phase of PECO’s SMPIP, which was completedon June 19, 2013, included the installation of an AMI communications network and the deployment of 600,000 smart meters tocommunicate with that network. On May 31, 2013, PECO and interested parties filed a Joint Petition for Settlement of the universaldeployment plan with the PAPUC which was approved without modification on August 15, 2013. The Joint Petition for Settlement supportsall material aspects of PECO’s universal deployment plan, including cost recovery, excluding certain amounts discussed below. Universaldeployment is the second phase of PECO’s SMPIP, under which PECO will deploy the remainder of the 1.6 million smart meters on anaccelerated basis by the end of 2014. In total, PECO currently expects to spend up to $595 million, excluding the cost of the original meters(as further described below), on its smart meter infrastructure and approximately 244Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) $120 million on smart grid investments through 2014 of which $200 million will be funded by SGIG as discussed below. As ofDecember 31, 2013, PECO has spent $423 million and $116 million on smart meter and smart grid infrastructure, respectively, notincluding the DOE reimbursements received to date. Pursuant to the ARRA of 2009, PECO and the DOE entered into a Financial Assistance Agreement to extend PECO $200 million innon-taxable SGIG funds of which $140 million relates to smart meter deployment and $60 million relates to smart grid infrastructure. As partof the agreement, the DOE has a conditional ownership interest in qualifying Federally-funded project property and equipment, which issubordinate to PECO’s existing mortgage. The SGIG funds are being used to offset the total impact to ratepayers of the smart meterdeployment required by Act 129. As of December 31, 2013, PECO has received $190 million of the $200 million in reimbursements.PECO’s outstanding receivable from the DOE for reimbursable costs was $3 million as of December 31, 2013, which has been recorded inOther accounts receivable, net on Exelon’s and PECO’s Consolidated Balance Sheets. On August 15, 2012, PECO suspended installation of smart meters for new customers based on a limited number of incidentsinvolving overheating meters. Following its own internal investigation and additional scientific analysis and testing by independent expertscompleted after September 30, 2012, PECO announced its decision to resume meter deployment work on October 9, 2012. PECO hasreplaced the previously installed meters with an alternative vendor’s meters. PECO is moving forward with the alternative meters duringuniversal deployment and continues to evaluate meters from several vendors and may use more than one meter vendor during universaldeployment. Following PECO’s decision, as of October 9, 2012 PECO will no longer use the original smart meters. For the meters that will nolonger be used, the accounting guidance requires that any difference between the carrying value and net realizable value be recognized in thecurrent period’s earnings, before considering potential regulatory recovery. The cost of the original meters, including installation and removalcosts, owned by PECO was approximately $17 million, net of approximately $16 million of reimbursements from the DOE andapproximately $2 million of depreciation. PECO requested and received approval from the DOE that the original meters continue to beallowable costs and that any agreement with the vendor will not be considered project income. In addition, PECO remains eligible for the full$200 million in SGIG funds. On August 15, 2013, PECO entered into an agreement with the original vendor, which was part of the finalagreement discussed below, under which PECO transferred the original uninstalled meters to the vendor and will receive $12 million inreturn, of which $7 million has been received as of December 31, 2013. On January 23, 2014, PECO entered a final agreement with thevendor pursuant to which PECO will be reimbursed for amounts incurred for the original meters and related installation and removal costs,via cash payments and rebates on future purchases of licenses, goods and services primarily through 2017. PECO previously had intendedto seek regulatory rate recovery in a future filing with the PAPUC of amounts not recovered from the vendor. As PECO believed such costswere probable of rate recovery based on applicable case law and past precedent on reasonably and prudently incurred costs, a regulatory assetwas established at the time of the removals. As of December 31, 2013 and 2012, $5 million and $17 million, respectively, was recorded onExelon’s and PECO’s Consolidated Balance Sheets. Pursuant to the January 23, 2014, vendor agreement, PECO will reclassify theregulatory asset balance as a receivable, with no gain or loss impacts on future results of operations. Energy Efficiency Programs (Exelon and PECO). PECO’s PAPUC-approved Phase I EE&C Plan had a four-year term that beganon June 1, 2009 and concluded on May 31, 2013. The Phase I plan set forth how PECO would meet the required reduction targetsestablished by Act 129’s EE&C provisions, 245Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) which included a 3% reduction in electric consumption in PECO’s service territory and a 4.5% reduction in PECO’s annual system peakdemand in the 100 hours of highest demand by May 31, 2013. The peak demand period ended on September 30, 2012 and PECO communicated its compliance with the reduction targets in apreliminary filing with the PAPUC on March 1, 2013. The final compliance report for all Phase I targets, was filed with the PAPUC onNovember 15, 2013. On March 29, 2013, PECO filed a Petition with the PAPUC to change the recovery period of certain Direct Load Control (DLC)Program costs necessary to implement the Phase I Plan. The Petition sought approval to allow PECO to recover $12 million in equipment,installation and information technology costs for its Residential DLC program with the amounts collected for the Phase I Plan. As the Phase IPlan was implemented at a cost less than originally budgeted, PECO proposed to recover these expenses from its Phase I Energy EfficiencyProgram Charge over-collection consistent with PAPUC guidance to recover all Phase I costs through Phase I funding. The PAPUCapproved PECO’s Petition on May 9, 2013. A regulatory liability was established for the DLC program costs that will be amortized as a creditto the income statement to offset the related depreciation expense during the same period. The PAPUC issued its Phase II EE&C implementation order on August 2, 2012, that provides energy consumption reductionrequirements for the second phase of Act 129’s EE&C programs, which went into effect on June 1, 2013. The order tentatively establishedPECO’s three-year cumulative consumption reduction target at 1,125,852 MWh, which was reaffirmed by the PAPUC on December 5,2012. Pursuant to the Phase II implementation order, PECO filed its three-year EE&C Phase II plan with the PAPUC on November 1, 2012.The plan sets forth how PECO will reduce electric consumption by at least 1,125,852 MWh in its service territory for the period June 1, 2013through May 31, 2016, adjusted for weather and extraordinary loads. The implementation order permits PECO to apply any excess savingsachieved during Phase I against its Phase II consumption reduction targets, with no reduction to its Phase II budget. In accordance with theAct 129 Phase II implementation order, at least 10% and 4.5% of the total consumption reductions must be through programs directed towardPECO’s public and low income sectors, respectively. If PECO fails to achieve the required reductions in consumption, it will be subject tocivil penalties of up to $20 million, which would not be recoverable from ratepayers. Act 129 mandates that the total cost of the plan may notexceed 2% of the electric company’s total annual revenue as of December 31, 2006. On March 15, 2013, PECO filed a Petition for Approval to amend its EE&C Phase II Plan to continue its DLC demand reductionprogram for mass market customers from June 1, 2013 to May 31, 2014. PECO proposed to fund the estimated $10 million costs of the one-year program by modifying incentive levels for other Phase II programs. On May 9, 2013, the PAPUC approved PECO’s amended EE&CPhase II plan. The costs of DLC program will be recovered through PECO’s Energy Efficiency Program Charge along with all other Phase IIPlan costs. On November 14, 2013, the PAPUC issued a Tentative Order on Act 129 demand reduction programs which seeks comments on aproposed demand response program methodology for future Act 129 demand reduction programs as well as demand response potential andwholesale prices suppression studies. The comment process is scheduled to be completed in the first quarter of 2014. Any decision reachedwould affect PECO’s EE&C Plan subsequent to its Phase II Plan. Alternative Energy Portfolio Standards (Exelon and PECO). In November 2004, Pennsylvania adopted the AEPS Act.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) PECO’s rate cap transition period, certain percentages of electric energy sold to Pennsylvania retail electric customers shall be generatedfrom certain alternative energy resources as measured in AECs. The requirement for electric energy that must come from Tier I alternativeenergy resources ranges from approximately 3.5% to 8% and the requirement for Tier II alternative energy resources ranges from 6.2% to10%. The required compliance percentages incrementally increase each annual compliance period, which is from June 1 through May 31,until May 31, 2021. These Tier I and Tier II alternative energy resources include acceptable energy sources as set forth in Act 129 and theAEPS Act. PECO has entered into five-year and ten-year agreements with accepted bidders, including Generation, totaling 452,000 non-solar and8,000 solar Tier I AECs annually in accordance with a PAPUC approved plan. The plan allowed PECO to bank AECs procured prior to 2011and use the banked AECs to meet its AEPS Act obligations over two compliance years ending May 2013. The PAPUC also approved theprocurement of Tier II AECs and supplemental AECs as well as the sale of excess AECs through independent third-party auctions or brokers. All AEPS administrative costs and costs of AECs incurred after December 31, 2010 are being recovered on a full and current basis fromdefault service customers through a surcharge. PECO’s second DSP Program eliminated the AEPS surcharge. Beginning in June 2013, AEPS compliance costs are being recoveredthrough the GSA. Investigation of Pennsylvania Retail Electricity Market (Exelon and PECO). On July 28, 2011, the PAPUC issued an orderoutlining the next steps in its investigation into the status of competition in Pennsylvania’s retail electric market. The PAPUC found that theexisting default service model presents substantial impediments to the development of a vibrant retail market in Pennsylvania and directedits Office of Competitive Markets Oversight to evaluate potential intermediate and long-term structural changes to the default service model.On March 1, 2012, the PAPUC issued the final order describing more detailed recommendations to be implemented prior to the expiration ofthe electric distribution company’s current default service plan and providing guidelines for electric distribution companies for development oftheir next default service plan. On October 12, 2012, the PAPUC approved PECO’s second DSP Program, which includes several newprograms to continue PECO’s support of retail market competition in Pennsylvania in accordance with the order issued by the PAPUC onDecember 15, 2011. Further, the PAPUC issued a final order on February 14, 2013, outlining its proposed end-state for default service,which included default service pricing for residential and small commercial customers based on three month full requirements contracts, fullrequirement contracts using hourly spot market pricing for large commercial and industrial default service customers, and the inclusion ofCAP customers in the customer choice programs. Pennsylvania Act 11 of 2012 (Exelon and PECO). On February 13, 2012, Act 11 was signed into law by the Governor. Act 11 seeksto clarify the PAPUC’s authority to approve alternative ratemaking mechanisms, which would allow for the implementation of a distributionsystem improvement charge (DSIC) in rates designed to recover capital project costs incurred to repair, improve or replace utilities’ agingelectric and natural gas distribution systems in Pennsylvania. Act 11 also includes a provision that allows utilities to use a fully projectedfuture test year under which the PAPUC may permit the inclusion of projected capital costs in rate base for assets that will be placed inservice during the first year rates are in effect. On August 2, 2012, the PAPUC issued a final order establishing rules and procedures toimplement the ratemaking provisions of Act 11.

Maryland Regulatory Matters 2011 Maryland Electric and Gas Distribution Rate Case (Exelon and BGE). In March 2011, the MDPSC issued acomprehensive rate order setting forth the details of the decision contained in its abbreviated electric and gas distribution rate order issued inDecember 2010. As part of the March 2011 comprehensive rate order, BGE was authorized to defer $19 million of costs as regulatory assets.These costs are being recovered over a 5-year period that began in December 2010 and include the deferral of $16 million of storm costsincurred in February 2010. The regulatory asset for the storm costs earns a regulated rate of return. 2012 Maryland Electric and Gas Distribution Rate Case (Exelon and BGE). On July 27, 2012, BGE filed an application forincreases to its electric and gas base rates with the MDPSC. On February 22, 2013, the MDPSC issued an order in BGE’s 2012 electric andnatural gas distribution rate case for increases in annual distribution service revenue of $81 million and $32 million, respectively. Theelectric distribution rate increase was set using an allowed return on equity of 9.75% and the gas distribution rate increase was set using anallowed return on equity of 9.60%. The approved electric and natural gas distribution rates became effective for services rendered on or afterFebruary 23, 2013. As part of the rate order, the MDPSC approved both recovery of and return on merger integration costs incurred duringthe test year, including severance. As a result, the order affirmed the treatment of $20 million of severance-related costs that BGE hadrecorded as a regulatory asset in 2012, consistent with prior MDPSC decisions. Additionally, BGE established a new regulatory asset of $8million related to non-severance merger integration costs, which includes $6 million of costs incurred during 2012. Current MDPSCtreatment of these merger integration regulatory assets is to provide recovery over a five year period. 2013 Maryland Electric and Gas Distribution Rate Case (Exelon and BGE). On May 17, 2013, BGE filed an application forincreases of $101 million and $30 million to its electric and gas base rates, respectively, with the MDPSC. The requested rates of return onequity in the application were 10.50% and 10.35% for electric and gas distribution, respectively. In addition to these requested rate increases,BGE’s application includes a request for recovery of incremental capital expenditures and operating costs associated with BGE’s proposedshort-term reliability improvement plan in response to a MDPSC order through a surcharge separate from base rates. On August 23, 2013,BGE filed an update to its rate request which altered the requested increase to electric base rates from $101 million to $83 million and therequested increase to gas base rates from $30 million to $24 million. On December 13, 2013, the MDPSC issued an order in BGE’s 2013electric and natural gas distribution rate case for increases in annual distribution service revenue of $34 million and $12 million, respectively.The electric distribution rate increase was set using an allowed return on equity of 9.75% and the gas distribution rate increase was set usingan allowed return on equity of 9.60%. The approved electric and natural gas distribution rates became effective for services rendered on orafter December 13, 2013. The MDPSC also conditionally approved five of the eight programs included in BGE’s proposed short-termreliability improvement plan. Commencement of the program and recovery are dependent on final MDPSC approval with the surchargestarting no earlier than April 1, 2014. Smart Meter and Smart Grid Investments (Exelon and BGE). In August 2010, the MDPSC approved a comprehensive smart gridinitiative for BGE that includes the planned installation of 2 million residential and commercial electric and gas smart meters at an expectedtotal cost of $480 million.

As of December 31, 2013 and December 31, 2012, BGE recorded a regulatory asset of $66 million and $31 million,respectively, representing incremental costs, depreciation and amortization, and a debt return on fixed assets related to its AMI program.Additionally, the MDPSC has determined that the cost recovery for the non-AMI meters that BGE retires will be considered in a futuredepreciation proceeding. The MDPSC continues to evaluate the impacts of a customer opt-out feature in BGE’s Smart Grid program. InMarch 2013, BGE filed a description of the overall additional costs associated with allowing customers to retain their current meter, and forradio frequency (RF)-Free and RF-Minimizing options related to the installation of their smart meters as well as a proposed cost recoverymechanism. The MDPSC held a hearing in August 2013 to consider the filings made by BGE and other Maryland electric utilities. Theultimate resolution related to this feature could affect BGE’s ability to demonstrate cost-effectiveness of the advanced metering system.Overall, BGE continues to believe the recovery of smart grid initiative costs in future rates is probable as BGE expects to be able todemonstrate that the program benefits exceed costs. Pursuant to the ARRA of 2009, BGE is a recipient of $200 million in federal fundingfrom the DOE for its smart grid and other related initiatives, which substantially reduces the total cost of these initiatives to BGE’sratepayers. The project to install the smart meters began in late April 2012. As of December 31, 2013, BGE had received $200 million inreimbursements from the DOE. New Electric Generation (Exelon and BGE). On April 12, 2012, the MDPSC issued an order directing BGE and two other Marylandutilities to enter into a contract for differences (CfD) with CPV Maryland, LLC (CPV), under which CPV will construct an approximately 700MW natural gas-fired combined-cycle generation plant in Waldorf, Maryland, that CPV projected will be in commercial operation by June 1,2015. The initial term of the proposed contract is 20 years. The CfD mandates that BGE and the other utilities pay (or receive) the differencebetween CPV’s contract prices and the revenues CPV receives for capacity and energy from clearing the unit in the PJM capacity market.The MDPSC’s Order requires the three Maryland utilities to enter into a CfD in amounts proportionate to their relative SOS load. On April 16, 2013, the MDPSC issued an order that required BGE to execute a specific form of contract with CPV, and the partiesexecuted the contract as of June 6, 2013. As of December 31, 2013, there is no impact on Exelon’s and BGE’s results of operations, cashflows and financial positions. Furthermore, the agreement does not become effective until the resolution of certain items, including all currentlitigation. On April 27, 2012, a civil complaint was filed in the U.S. District Court for the District of Maryland by certain unaffiliated parties thatchallenges the actions taken by the MDPSC on Federal law grounds. On October 24, 2013, the U.S. District Court issued a judgment orderfinding that the MDPSC’s Order directing BGE and the two other Maryland utilities to enter into a CfD, which assures that CPV receives aguaranteed fixed price regardless of the price set by the federally regulated wholesale market, violates the Supremacy Clause of the UnitedStates Constitution. On November 22, 2013, the MDPSC and CPV appealed the District Court’s ruling to the United States Court ofAppeals for the Fourth Circuit. On May 4, 2012, BGE filed a petition in the Circuit Court for Anne Arundel County, Maryland, seeking judicial review of the MDPSCorder under state law. That petition was subsequently transferred to the Circuit Court for Baltimore City and consolidated with similar appealsthat have been filed by other interested parties. On October 1, 2013, the Circuit Court Judge issued a Memorandum Opinion and Orderfinding the decisions of the MDPSC were within its statutory authority under 249Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

This decision is separate from the judgment in the federal litigation that the MDPSC Order is unconstitutional and the CfD isunenforceable under federal law. The federal judgment, if upheld, would prevent enforcement of the CfD even if the Circuit Court decisionstands. On October 29, 2013, BGE and the two other Maryland utilities appealed the Circuit Court’s ruling to the Maryland Court of SpecialAppeals. Depending on the ultimate outcome of the pending state and federal litigation, on the eventual market conditions, and on the manner ofcost recovery as of the effective date of the agreement, the CfD could have a material impact on Exelon and BGE’s results of operations, cashflows and financial positions. Exelon believes that this and other states’ projects may have artificially suppressed capacity prices in PJM and may continue to do so infuture auctions to the detriment of Exelon’s market driven position. In addition to this litigation, Exelon is working with other marketparticipants to implement market rules that will appropriately limit the market suppressing effect of such state activities. MDPSC Derecho Storm Order (Exelon and BGE). Following the June 2012 Derecho storm which hit the mid-Atlantic regioninterrupting electrical service to a significant portion of the State of Maryland, the MDPSC issued an order on February 27, 2013 requiringBGE and other Maryland utilities to file several comprehensive reports with short-term and long-term plans to improve reliability and gridresiliency that were due at various times before August 30, 2013. On September 3, 2013, BGE filed a comprehensive long term assessment examining potential alternatives for improving theresiliency of the electric grid and a staffing analysis reviewing historical staffing levels as well as forecasting staffing levels necessary undervarious storm scenarios. BGE currently cannot predict the outcome of these proceedings, which may result in increased capital expendituresand operating costs. The Maryland Strategic Infrastructure Development and Enhancement Program (Exelon and BGE). In February 2013, theMaryland General Assembly passed legislation intended to accelerate gas infrastructure replacements in Maryland by establishing amechanism for gas companies to promptly recover reasonable and prudent costs of eligible infrastructure replacement projects separate frombase rate proceedings. On May 2, 2013, the Governor of Maryland signed the legislation into law; which took effect June 1, 2013. Under thenew law, following a proceeding before the MDPSC and with the MDPSC’s approval of the eligible infrastructure replacement projects alongwith a corresponding surcharge, BGE could begin charging gas customers a monthly surcharge for infrastructure costs incurred after June 1,2013. The legislation includes caps on the monthly surcharges to residential and non-residential customers, and would require an annualtrue-up of the surcharge revenues against actual expenditures. Investment levels in excess of the cap would be recoverable in a subsequentgas base rate proceeding at which time all costs for the infrastructure replacement projects would be rolled into gas distribution rates.Irrespective of the cap, BGE is required to file a gas rate case every five years under this legislation. On August 2, 2013, BGE filed itsinfrastructure replacement plan and associated surcharge. The MDPSC held evidentiary hearings on BGE’s proposed plan and surchargefrom November 12, 2013 through November 14, 2013. On January 29, 2014, the MDPSC issued a decision conditionally approving thefirst five years of BGE’s plan and surcharge. BGE must submit a list detailing specific projects planned for 2014 to the MDPSC for approvalwithin 30 days of the decision. Upon approval of the project list by the MDPSC, BGE will be able to implement the surcharge rates on gascustomers’ bills. The new surcharges are expected to take effect in second quarter of 2014. In addition, BGE will be subject to an annualindependent audit to review plan performance and progress. 250Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Federal Regulatory Matters Transmission Formula Rate (Exelon, ComEd and BGE). ComEd’s and BGE’s transmission rates are each established based on aFERC-approved formula. ComEd’s most recent annual formula rate update filed in April 2013 reflects 2012 actual costs plus forecasted 2013 capital additions.The update resulted in a revenue requirement of $488 million plus a $25 million adjustment related to the reconciliation of 2012 actual costsfor a net revenue requirement of $513 million. This compares to the May 2012 updated revenue requirement of $450 million offset by a $5million reduction related to the reconciliation of 2011 actual costs for a net revenue requirement of $445 million. The increase in the revenuerequirement was primarily driven by increased capital investment, higher pension and post-retirement healthcare costs, and higher operatingand maintenance costs. The 2013 net revenue requirement became effective June 1, 2013, and is being recovered over the period extendingthrough May 31, 2014. The regulatory asset associated with the true-up is being amortized as the associated amounts are recovered throughrates. ComEd’s updated formula transmission rate currently provides for a weighted average debt and equity return on transmission rate baseof 8.70%, a decrease from the 8.91% return previously authorized. The decrease in return was primarily due to lower interest rates onComEd’s long-term debt outstanding. As part of the FERC-approved settlement of ComEd’s 2007 transmission rate case, the rate of returnon common equity is 11.5% and the common equity component of the ratio used to calculate the weighted average debt and equity return forthe formula transmission rate is currently capped at 55%. BGE’s most recent annual formula rate update filed in April 2013 reflects actual 2012 expenses and investments plus forecasted 2013capital additions. The update resulted in a revenue requirement of $158 million offset by a $1 million reduction related to the reconciliation of2012 actual costs for a net revenue requirement of $157 million. This compares to the April 2012 updated revenue requirement of $156million increased by $2 million related to the reconciliation of 2011 actual costs for a net revenue requirement of $158 million. The decreasein the revenue requirement was primarily driven by a lower allowed rate of return associated with a reduced equity ratio and reduced ratebase, offset partially by higher depreciation and operating and maintenance costs. The 2013 net revenue requirement became effectiveJune 1, 2013, and is being recovered over the period extending through May 31, 2014. The regulatory liability associated with the true-up isbeing amortized as the associated amounts are recovered through rates. BGE’s updated formula transmission rate currently provides for a weighted average debt and equity return on transmission rate base of8.35%, a decrease from the 8.43% included in the prior year formula update. The decrease in return was primarily due to a debt issuance in2012 and lower interest rates on BGE’s debt outstanding. As part of the FERC-approved settlement in 2006 of BGE’s 2005 transmission ratecase, the base rate of return on common equity for BGE’s electric transmission business for new transmission projects placed in service onand after January 1, 2006 is 11.3%, inclusive of a 50 basis point incentive for participating in PJM. FERC Transmission Complaint (Exelon and BGE). On February 27, 2013, consumer advocates and regulators from the District ofColumbia, New Jersey, Delaware and Maryland, and the Delaware Electric Municipal Cooperatives (the parties), filed a complaint at FERCagainst BGE and the Pepco Holdings, Inc. companies relating to their respective transmission formula rates. BGE’s formula rate includes a10.8% base rate of return on common equity (ROE) for most investments included in its rate base and 11.3% for the remainingtransmission investment (the latter of which is conditioned upon crediting the first 50 basis points of any incentive ROE adders). The partiesseek a reduction in the 251Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) base return on equity to 8.7% and changes to the formula rate process. FERC docketed the matter and set April 3, 2013 as the deadline forinterventions, protests and answers. Under FERC rules, the earliest date from which the base return on equity could be adjusted andrefunds required is the date of the complaint. On March 19, 2013, BGE filed a motion to dismiss or sever the complaint. As of December 31,2013, BGE cannot predict the likelihood or a reasonable estimate of the amount of a change, if any, in the allowed base return on equity, or areasonable estimate of the refund period start date. While BGE cannot predict the outcome of this matter, if FERC orders a reduction ofBGE’s base return on equity to 8.7% (while retaining the 50 basis points of any incentives that were credited to the base return on equity forcertain new transmission investment), the estimated annual impact would be a reduction in revenues of approximately $10 million. PJM Transmission Rate Design and Operating Agreements (Exelon, ComEd, PECO and BGE). PJM Transmission RateDesign specifies the rates for transmission service charged to customers within PJM. Currently, ComEd, PECO and BGE incur costs basedon the existing rate design, which charges customers based on the cost of the existing transmission facilities within their load zone and thecost of new transmission facilities based on those who benefit from those facilities. In April 2007, FERC issued an order concluding thatPJM’s current rate design for existing facilities is just and reasonable and should not be changed. In the same order, FERC held that thecosts of new facilities 500 kV and above should be socialized across the entire PJM footprint and that the costs of new facilities less than 500kV should be allocated to the customers of the new facilities who caused the need for those facilities. After FERC ultimately denied allrequests for rehearing on all issues, several parties filed petitions in the U.S. Court of Appeals for the Seventh Circuit for review of thedecision. On August 6, 2009, that court issued its decision affirming FERC’s order with regard to the costs of existing facilities but reversingand remanding to FERC for further consideration its decision with regard to the costs of new facilities 500 kV and above. On March 30, 2012,FERC issued an order on remand affirming the cost allocation in its April 2007 order. On March 22, 2013, FERC issued an order denyingrehearing of its March 30, 2012 Order and made it clear that the cost allocation at issue concerns only projects approved prior to February 1,2013. A number of entities have filed appeals of the FERC orders. ComEd, and BGE anticipate that all impacts of any rate design changeseffective after December 31, 2006 and June 30, 2006, respectively, should be recoverable through retail rates and, thus, the rate designchanges are not expected to have a material impact on their respective results of operations, cash flows or financial position. PECOanticipates that all impacts of any rate design changes should be recoverable through the transmission service charge rider approved inPECO’s 2010 electric distribution rate case settlement and, thus, the rate design changes are not expected to have a material impact onPECO’s results of operations, cash flows or financial position. To the extent that any rate design changes are retroactive to periods prior toJanuary 1, 2011, however, there may be an impact on PECO’s results of operations. On October 11, 2012, the PJM Transmission Owners filed with FERC a cost allocation for new transmission facilities asking that thenew cost allocation methodology apply to all transmission approved by the PJM Board on or after February 1, 2013. The proposedmethodology is a hybrid methodology that would socialize 50% of the costs of new facilities at 500kV and above and double-circuit 345kVlines, and allocate the remaining 50% to direct beneficiaries. For all other facilities, the costs would be allocated to the direct beneficiaries. OnMarch 22, 2013, FERC issued an order accepting the cost allocation with minor exceptions and requiring a compliance filing on those fewissues within 120 days of the order. The compliance filing was made on July 22, 2013. ComEd, PECO and BGE are committed to the construction of transmission facilities under their operating agreements with PJM tomaintain system reliability. ComEd, PECO and BGE will work with 252Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

ComEd, PECO and BGE’s estimated commitmentsare as follows: Total 2014 2015 2016 2017 2018 ComEd $486 $134 $173 $177 $2 $— PECO 133 32 29 40 24 8 BGE 400 42 83 95 87 93 PJM Minimum Offer Price Rule (Exelon and Generation). PJM’s capacity market rules include a Minimum Offer Price Rule(MOPR) that is intended to preclude sellers from artificially suppressing the competitive price signals for generation capacity. The proceedingsleading to FERC’s approval of the MOPR were extensive, and there have been numerous changes to the MOPR and litigation related to itsince it was originally implemented. For example, in 2011 the parties disputed numerous elements of the MOPR including: (i) the defaultprice that should apply to bids found subject to the MOPR, (ii) the duration of the MOPR and (iii) the application of the MOPR to self-supplying capacity and state-sponsored capacity. The FERC orders approving that MOPR have been appealed to the United States Court ofAppeals for the Third Circuit. A resolution of that appeal is not expected until sometime in 2014. In May 2012 (based on the MOPR provisions the FERC approved in 2011), PJM announced the results of its capacity auction coveringthe delivery year ending May 31, 2016. Several new units with state-sanctioned subsidy contracts cleared in the auction at prices below theMOPR. Potentially, these states could expand such state-sanctioned subsidy programs or other states may seek to establish similarprograms. Generation believed that further revisions to that MOPR were necessary to ensure that the potential to artificially reduce capacityauction prices is appropriately limited in PJM. In early December 2012, PJM filed a new MOPR for approval at the FERC, which Exelonbelieved would be more effective in preventing state-sanctioned subsidy contracts from artificially reducing capacity prices. Generation wasactively involved in the process through which those MOPR changes were developed and supported the changes. On May 3, 2013, theFERC issued its order. While the FERC order accepted certain aspects of the proposal that Exelon supported (such as applying the MOPR toall of PJM and not just certain zones within PJM), the FERC required PJM to retain a key element of its previous MOPR structure, the unit-specific exemption, an element that Exelon had supported removing. Several entities, including two capacity suppliers that Exelon has beenworking with sought rehearing of that order. In May 2013 (based on the MOPR provisions the FERC approved earlier that month), PJM announced the results of its capacityauction covering the delivery year ending May 31, 2017. Exelon is working with PJM stakeholders on several proposed changes to the PJMtariff aimed at ensuring that capacity resources (including those with state-sanctioned subsidy contracts, excessive imported capacityresources and certain limited availability demand response resources) cannot inappropriately affect capacity auction prices in PJM. Market-Based Rates (Exelon, Generation, ComEd, PECO and BGE). Generation, ComEd, PECO and BGE are public utilities forpurposes of the Federal Power Act and are required to obtain FERC’s acceptance of rate schedules for wholesale electricity sales. Currently,Generation, ComEd, PECO and BGE have authority to execute wholesale electricity sales at market-based rates. As is customary withmarket-based rate schedules, FERC has reserved the right to suspend market-based rate authority on a retroactive basis if it subsequentlydetermines that Generation, ComEd, PECO or BGE has violated the terms and conditions of its tariff or the Federal Power Act. FERC isalso authorized to order refunds in certain instances if it finds that the market-based rates are not just and reasonable under the FederalPower Act. 253Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) As required by FERC’s regulations, as promulgated in the Order No. 697 series, Generation, ComEd, PECO and BGE file marketpower analyses using the prescribed market share screens to demonstrate that Generation, ComEd, PECO and BGE qualify for market-based rates in the regions where they are selling energy, capacity, and ancillary services under market-based rate tariffs. FERC accepted the2008 filings on September 16, 2008, January 15, 2009 and September 2, 2009 and accepted the 2009 filings on July 28, 2009, October 26,2009, February 23, 2010 and April 30, 2010, affirming Exelon’s affiliates continued right to make sales at market-based rates. Theseanalyses must examine historic test period data and must be updated every three years on a prescribed schedule. Generation, ComEd,PECO and BGE filed an updated analysis for the Northeast Region, which includes PJM, in late 2010, based on 2009 historic test perioddata. On June 22, 2011, FERC issued an order confirming Generation’s continued authority to charge market based rates, based onGeneration’s most recent updated analysis filed in 2010, stating that any market power concerns are adequately addressed by PJM’smonitoring and mitigation programs. On December 30, 2013, Generation, ComEd, PECO and BGE filed its updates analysis for theNortheast Region, based on 2012 historic test period data and FERC has not yet acted on the filing. Similarly, on June 29, 2012,Generation, ComEd, BGE and PECO filed their updated market power analysis for the Central Region which the FERC accepted onNovember 13, 2012, and on December 23, 2011, Generation filed its updated market power analysis for the Southeast Region which theFERC accepted on October 10, 2012. On December 21, 2012, Generation, ComEd, BGE and PECO filed their updated market poweranalysis for the SPP region, which the FERC accepted on October 8, 2013. Reliability Pricing Model (Exelon, Generation and BGE). PJM’s RPM Base Residual Auctions take place approximately 36months ahead of the scheduled delivery year. The most recent auction for the delivery year ending May 31, 2017 occurred in May 2013. License Renewals (Exelon and Generation). On June 22, 2011, Generation submitted applications to the NRC to extend theoperating licenses of Limerick Units 1 and 2 by 20 years. The current operating licenses for Limerick Units 1 and 2 expire in 2024 and 2029,respectively. In June 2012, the United States Court of Appeals for the DC Circuit vacated the NRC’s temporary storage rule on the groundsthat the NRC should have conducted a more comprehensive environmental review to support the rule. The temporary storage rule (alsoreferred to as the “waste confidence decision”) recognizes that licensees can safely store spent nuclear fuel at nuclear plants for up to 60 yearsbeyond the original and renewed licensed operating life of the plants and that licensing renewal decisions do not require discussion of theenvironmental impact of spent fuel stored on site. In August 2012, the NRC placed a hold on issuing new or renewed operating licenses thatdepend on the temporary storage rule until the court’s decision is addressed. In September 2012, the NRC directed NRC Staff to revise thetemporary storage rule which is now not expected until October 3, 2014. Generation does not expect the NRC to issue license renewals untilthe end of 2014, at the earliest. On May 29, 2013, Generation submitted applications to the NRC to extend the operating licenses of Byron Units 1 and 2 andBraidwood Units 1 and 2 by 20 years. The current operating licenses for Byron Units 1 and 2 expire in 2024 and 2026, respectively. Thecurrent operating licenses for Braidwood Units 1 and 2 expire in 2026 and 2027, respectively. Generation does not expect the NRC to issuelicense renewals for Byron and Braidwood until 2015 at the earliest. On August 29, 2012 and August 30, 2012, Generation submitted hydroelectric license applications to the FERC for 46-year licensesfor the Conowingo Hydroelectric Project (Conowingo) and the Muddy Run Pumped Storage Facility Project (Muddy Run), respectively. 254Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The FERC extended the deadline to January 31, 2014 to file a water quality certification application pursuant to Section 401 of the CleanWater Act (CWA) with the MDE for Conowingo. Generation is working with stakeholders to resolve licensing issues, including: (1) waterquality, (2) fish passage and habitat, and (3) sediment. On January 30, 2014, Exelon filed a water quality certification application pursuant toSection 401 of the CWA with MDE for Conowingo, addressing these and other issues, although Generation cannot currently predict theconditions that ultimately may be imposed. Resolution of these issues relating to Conowingo may have a material effect on Generation’sresults of operations and financial position through an increase in capital expenditures and operating costs. On August 29, 2013, Exelon filed a water quality certification application pursuant to Section 401 of the CWA with PA DEP for MuddyRun, addressing these and other issues that included certain commitments made by Generation. The financial impact associated with thesecommitments is estimated to be in the range of $20 million to $30 million, and will include both an increase in capital expenditures as wellas an increase in operating expenses. Exelon anticipates that the PA DEP will issue the water quality certification pursuant to Section 401 ofthe CWA for Muddy Run in the first quarter of 2014. Based on the latest FERC procedural schedule, the FERC licensing process is not expected to be completed prior to the expiration ofMuddy Run’s current license on August 31, 2014, and the expiration of Conowingo’s license on September 1, 2014. However, the stationswould continue to operate under annual licenses until FERC takes action on the 46-year license applications. The stations are currentlybeing depreciated over their useful lives, which includes the license renewal period. As of December 31, 2013, $33 million of direct costsassociated with relicensing efforts have been capitalized. Regulatory Assets and Liabilities (Exelon, ComEd, PECO and BGE) Exelon, ComEd, PECO and BGE prepare their consolidated financial statements in accordance with the authoritative guidance foraccounting for certain types of regulation. Under this guidance, regulatory assets represent incurred costs that have been deferred because oftheir probable future recovery from customers through regulated rates. Regulatory liabilities represent the excess recovery of costs or accruedcredits that have been deferred because it is probable such amounts will be returned to customers through future regulated rates or representbillings in advance of expenditures for approved regulatory programs. 255Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Pension and other postretirement benefits. As of December 31, 2013, Exelon had regulatory assets of $3,015 million andregulatory liabilities of $45 million related to ComEd’s and BGE’s portion of deferred costs associated with Exelon’s pension plans andComEd’s, PECO’s and BGE’s portion of deferred costs associated with Exelon’s other postretirement benefit plans. PECO’s pensionregulatory recovery is based on cash contributions and is not included in the regulatory asset (liability) balances. The regulatory asset(liability) is amortized in proportion to the recognition of prior service costs (gains), transition obligations and actuarial losses (gains)attributable to Exelon’s pension and other postretirement benefit plans determined by the cost recognition provisions of the authoritativeguidance for pensions and postretirement benefits. ComEd, PECO and BGE will recover these costs through base rates as allowed in theirmost recently approved regulated rate orders. The pension and other postretirement benefit regulatory asset balance includes a regulatoryasset established at the date of the merger related to BGE’s portion of the deferred costs associated with legacy Constellation’s pension andother postretirement benefit plans. The BGE-related regulatory asset is being amortized over a period of approximately 12 years, whichgenerally represents the expected average remaining service period of plan participants at the date of the merger. See Note 16—RetirementBenefits for additional detail. No return is earned on Exelon’s regulatory asset. Deferred income taxes. These costs represent the difference between the method by which the regulator allows for the recovery ofincome taxes and how income taxes would be recorded under GAAP. Regulatory assets and liabilities associated with deferred income taxes,recorded in compliance with the authoritative guidance for accounting for certain types of regulation and income taxes, include the deferred taxeffects associated principally with accelerated depreciation accounted for in accordance with the ratemaking policies of the ICC, PAPUC andMDPSC, as well as the revenue impacts thereon, and assume continued recovery of these costs in future transmission and distributionrates. For ComEd and BGE, this amount includes the impacts of a reduction in the deductibility, for Federal income tax purposes, of certainretiree health care costs pursuant to the March 2010 Health Care Reform Acts. ComEd was granted recovery of these additional income taxeson May 24, 2011 in the ICC’s 2010 Rate Case order. The recovery period for these costs is through May 31, 2014. For BGE, these additionalincome taxes are being amortized over a 5-year period that began in March 2011 in accordance with the MDPSC’s March 2011 rate order. SeeNote 14—Income Taxes and Note 16—Retirement Benefits for additional information. ComEd, PECO and BGE are not earning a return onthe regulatory asset in base rates. AMI programs. For ComEd, this amount represents operating and maintenance expenses and meter costs associated with ComEd’sAMI pilot program approved in the May 24, 2011, ICC order in ComEd’s 2010 rate case. The recovery periods for operating and maintenanceexpenses and meter costs are through May 31, 2014, and January 1, 2020, respectively. As of December 31, 2013, ComEd had regulatoryassets of $35 million related to accelerated depreciation costs resulting from the early retirements of non-AMI meters, which will be amortizedover an average ten year period pursuant to the ICC approved AMI Deployment plan. ComEd is earning a return on the meter costs. ForPECO, this amount represents accelerated depreciation and filing and implementation costs relating to the PAPUC-approved Smart MeterProcurement and Installation Plan as well as the return on the un-depreciated investment, taxes, and operating and maintenance expenses.The approved plan allows for recovery of filing and implementation costs incurred through December 31, 2012. In addition, the approved planprovides for recovery of program costs, which includes depreciation on new equipment placed in service, beginning in January 2011 on fulland current basis, which includes interest income or expense on the under or over recovery. The approved plan also provides for recovery ofaccelerated depreciation on PECO’s non-AMI meter assets over a 10-year period ending December 31, 2020. For BGE, this amountrepresents smart grid pilot program costs as well as the incremental costs associated with implementing full deployment of a smart gridprogram.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) pilot program costs of $11 million were deferred in a regulatory asset, and, beginning with the MDPSC’s March 2011 rate order, is earningBGE’s most current authorized rate of return. In August 2010, the MDPSC approved a comprehensive smart grid initiative for BGE,authorizing BGE to establish a separate regulatory asset for incremental costs incurred to implement the initiative, including the netdepreciation and amortization costs associated with the meters, and an authorized rate of return on these costs, a portion of which is notrecognized under GAAP until cost recovery begins. Additionally, the MDPSC order requires that BGE prove the cost-effectiveness of theentire smart grid initiative prior to seeking recovery of the costs deferred in these regulatory assets. Therefore, the commencement andtiming of the amortization of these deferred costs is currently unknown. BGE’s AMI regulatory asset excludes costs for non-AMI meters beingreplaced by AMI meters, as the MDPSC has ordered that the cost recovery for non-AMI meters will be considered in a future depreciationproceeding. AMI Meter Events. This amount represents the remaining cost value of the original smart meters, net of accumulated depreciation,DOE reimbursements and amounts recovered from the vendor, of smart meter deployment that will no longer be used, including installationand removal costs. PECO intended to seek through regulatory rate recovery in a future filing with the PAPUC, any amounts no recoveredfrom the vendor. PECO believed the amounts incurred for the original meters and related installation and removal costs were probable ofrecovery based on applicable case law and past precedent on reasonably and prudently incurred costs. As such, PECO has deferred thesecosts on Exelon’s and PECO’s Consolidated Balance Sheet. PECO will not earn a return on the recovery of these costs. Under-recovered distribution services costs. Under EIMA, which became effective in the fourth quarter of 2011, ComEd isallowed recovery of distribution services costs through a formula rate tariff. The legislation provides for an annual reconciliation of the revenuerequirement in effect to reflect the actual costs that the ICC determines are prudently and reasonably incurred in a given year. The overrecovery associated with the 2011 reconciliation was recovered through rates over a one-year period, that began in January 2013. The underrecovery associated with the 2012 reconciliation will be recovered through rates over a one-year period beginning in January 2014. ComEd isearning a return on these costs. The regulatory asset also includes costs associated with certain one-time events, such as large storms,which will be recovered over a five-year period. As of December 31, 2013, the regulatory asset was comprised of $377 million for the annualreconciliation and $86 million related to significant one-time events. In addition to $58 million in deferred storm costs, net of amortization, theDecember 31, 2013 balance related to significant one-time events contains $28 million of merger and integration related costs, net ofamortization, incurred as a result of the merger. As of December 31, 2012, the regulatory asset was comprised of $125 million for the annualreconciliation and $84 million related to significant one-time events. In addition to $58 million in deferred storm costs, net of amortization, theDecember 31, 2012 balance related to significant one-time events contains $26 million of merger and integration related costs, net ofamortization, incurred as a result of the merger. See Note 4—Mergers and Acquisitions for additional information. Debt costs. Consistent with rate recovery for ratemaking purposes, ComEd’s, PECO’s and BGE’s recoverable losses on reacquiredlong-term debt related to regulated operations are deferred and amortized to interest expense over the life of the new debt issued to finance thedebt redemption or over the life of the original debt issuance if the debt is not refinanced. Interest-rate swap settlements are deferred andamortized over the period that the related debt is outstanding or the life of the original issuance retired. These debt costs are used in thedetermination of the weighted cost of capital applied to rate base in the rate-making process. ComEd and BGE are not earning a return on therecovery of these costs, while PECO is earning a return on the premium of the cost of the reacquired debt through base rates. 259Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

BGE is earning a regulated return on the regulatory asset included in base rates. Asset retirement obligations. These costs represent future legally required removal costs associated with existing asset retirementobligations. PECO will begin to earn a return on, and a recovery of, these costs once the removal activities have been performed. ComEdand BGE will recover these costs through future depreciation rates and will earn a return on these costs once the removal activities havebeen performed. See Note 15—Asset Retirement Obligations for additional information. MGP remediation costs. Recovery of these items was granted to ComEd in the July 26, 2006, ICC rate order. For PECO, thesecosts are recoverable through rates as affirmed in the 2010 approved natural gas distribution rate case settlement. While BGE does not havea rider for MGP clean-up costs, BGE has historically received recovery of actual clean-up costs on a site-specific basis in distribution rates.The period of recovery for both ComEd and PECO will depend on the timing of the actual expenditures. ComEd and PECO are not earning areturn on the recovery of these costs. For BGE, $5 million of clean-up costs incurred during the period from July 2000 through November2005 and an additional $1 million from December 2005 through November 2010 are recoverable through rates in accordance with MDPSCorders.

Financial swap with Generation. To fulfill a requirement of the Illinois Settlement Legislation, ComEd entered into a five-yearfinancial swap contract with Generation that expired on May 31, 2013. Since the swap contract was deemed prudent by the IllinoisSettlement Legislation, ensuring ComEd of full recovery in rates, the changes in fair value each period were recorded by ComEd as well asan offsetting regulatory asset or liability. ComEd did not earn (pay) a return on the regulatory asset (liability). The basis for the mark-to-marketderivative asset or liability position was based on the difference between ComEd’s cost to purchase energy on the spot market and thecontracted price.

As a result of the deregulation of electric generation, BGE ceased to meet therequirements for accounting for a regulated business for the previous electric generation portion of its business. As a result, BGE wrote-off itsentire individual, generation-related regulatory assets and liabilities and established a single, generation-related regulatory asset to becollected through its regulated rates, which is being amortized on a basis that approximates the pre-existing individual regulatory assetamortization schedules. The portion of this regulatory asset that does not earn a regulated rate of return were $37 million as of December 31,2013, and $47 million as of December 31, 2012. BGE will continue to amortize this amount through 2017. Rate stabilization deferral. In June 2006, Senate Bill 1 was enacted in Maryland and imposed a rate stabilization measure thatcapped rate increases by BGE for residential electric customers at 15% from July 1, 2006, to May 31, 2007. As a result, BGE recorded aregulatory asset on its Consolidated Balance Sheets equal to the difference between the costs to purchase power and the revenues collectedfrom customers, as well as related carrying charges based on short-term interest rates from July 1, 2006, to May 31, 2007.

ComEd recorded a regulatory asset for the cumulative under-collections in 2008 and 2009.Recovery of the initial regulatory asset was completed over an approximate 14-month time frame which began in April 2010. The recovery orrefund of the difference in the uncollectible accounts expense applicable to the years starting with January 1, 2010, will take place over a 12-month time frame beginning in June of the following year.

Merger and Acquisitions Merger with Constellation (Exelon, Generation, ComEd, PECO and BGE) Description of Transaction On March 12, 2012, Exelon completed the merger contemplated by the Merger Agreement among Exelon, Bolt AcquisitionCorporation, a wholly owned subsidiary of Exelon (Merger Sub), and Constellation. As a result of that merger, Merger Sub was merged intoConstellation (the Initial Merger) and Constellation became a wholly owned subsidiary of Exelon. Following the completion of the InitialMerger, Exelon and Constellation completed a series of internal corporate organizational restructuring transactions. Constellation mergedwith and into Exelon, with Exelon continuing as the surviving corporation (the Upstream Merger). Simultaneously with the UpstreamMerger, Constellation’s interest in RF HoldCo LLC, which holds Constellation’s interest in BGE, was transferred to Exelon Energy DeliveryCompany, LLC, a wholly owned subsidiary of Exelon that also owns Exelon’s interests in ComEd and PECO. Following the UpstreamMerger and the transfer of RF HoldCo LLC, Exelon contributed to Generation certain subsidiaries, including those with generation andcustomer supply operations that were acquired from Constellation as a result of the Initial Merger and the Upstream Merger. 265(a)(b)(a)(b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Regulatory Matters In February 2012, the MDPSC issued an Order approving the Exelon and Constellation merger. As part of the MDPSC Order, Exelonagreed to provide a package of benefits to BGE customers, the City of Baltimore and the State of Maryland, resulting in an estimated directinvestment in the State of Maryland of approximately $1 billion. The following costs were recognized after the closing of the merger and are included in Exelon’s, Generation’s and BGE’s ConsolidatedStatements of Operations and Comprehensive Income for the year ended December 31, 2012.

The direct investment estimate includes $95 million to $120 million relating to the construction of a headquarters building in Baltimorefor Generation’s competitive energy businesses. On March 20, 2013, Generation signed a 20 year lease agreement that is contingent uponthe developer obtaining all required approvals, permits and financing for the construction of the building. Once required approvals arereceived and financing conditions are met, construction will commence and the building is expected to be ready for occupancy inapproximately 2 years after building construction commences. The direct investment estimate also includes $600 million to $650 million for Exelon’s and Generation’s commitment to develop orassist in development of 285—300 MWs of new generation in Maryland, expected to be completed over a period of 10 years. The MDPSCOrder contemplates various options for complying with the new generation development commitments, including building or acquiringgenerating assets, making subsidy or compliance payments, or in circumstances in which the generation build is delayed, making liquidateddamages payments. Exelon and Generation expect that the majority of these commitments will be satisfied by building or acquiringgenerating assets and, therefore, will be primarily capital in nature and recognized as incurred. If in the future Exelon determines that it isprobable that it will make subsidy, compliance or liquidated damages payments related to the new generation development commitments,Exelon will record a liability at that time. As of December 31, 2013, it is reasonably possible that Exelon will be required to make subsidy or 266(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) liquidated damages payments of approximately $40 million rather than build one of the generation projects contemplated by thecommitments, given that the generation build is dependent upon the passage of legislation and other conditions that Exelon does not control. On July 26, 2013, Generation executed an engineering procurement and construction contract to expand its Perryman, Maryland sitewith 120MW of new natural gas-fired generation to satisfy certain of these commitments and achievement of commercial operation isexpected in 2015. In December 2013, Generation acquired the Fourmile Ridge Project in western Maryland and executed a wind turbinesupply agreement for construction of a 32.5 MW project targeted for commercial operation in November 2014. This project will satisfy aportion of the 125 MW Tier I land-based renewables commitment. See Note 22—Commitments and Contingencies for additionalinformation. As of December 31, 2013, amounts reflected in the Exelon and Generation consolidated financial statements include $24million of capital expenditures and $6 million of development costs included within operating and maintenance expense associated withpursuit of these commitments for new generation in the State of Maryland. Associated with certain of the regulatory approvals required for the merger, on November 30, 2012, a subsidiary of Generation soldthree Maryland generating stations and associated assets, Brandon Shores and H.A. Wagner in Anne Arundel County, Maryland, and C.P.Crane in Baltimore County, Maryland, to Raven Power Holdings LLC (Raven Power), a subsidiary of Riverstone Holdings LLC. The saleagreement included a base price with purchase price adjustments based on fuel inventory, working capital, capital expenditures, and timingof the closing, resulting in net proceeds from the sale of approximately $371 million. Decisions by certain market participants to removethemselves from the bidding process, combined with the deadlines and limitations on the pool of potential buyers imposed by the mergerapproval orders, resulted in realized sales proceeds below Generation’s estimated fair value of the Maryland generating stations.Consequently, Exelon and Generation recorded a pre-tax loss of $272 million in 2012 to reflect the difference between the sales price and thecarrying value of the generating stations and associated assets. In the first quarter of 2013, Exelon and Generation recorded a pre-tax gain of$8 million to reflect the final settlement of the sales price with Raven Power. In connection with the sale of the Maryland generating stations, Exelon agreed to indemnify Raven Power for certain costs associatedwith the treatment of hazardous substances at off-site disposal facilities and any claims arising as a result of, or in connection with, any toxictort, natural resource damages, loss of life or injury to persons due to releases of, or exposure to hazardous substances in connection withRaven Power’s remediation of environmental contamination or Exelon’s non-compliance with environmental laws or permits prior to theclosing date of the sale. Pursuant to the MDPSC merger approval conditions, BGE is restricted from paying any dividend on its common shares through theend of 2014, was required to maintain specified minimum capital and O&M expenditure levels in 2012 and 2013, and is not permitted toreduce employment levels due to involuntary attrition associated with the merger integration process for two years following the closing of themerger. Additionally, BGE is subject to other merger approval conditions to enhance BGE’s ring-fencing measures established by order of theMDPSC. Subsequent to the merger, Generation discovered that, for the first two weeks following the merger, due to a software error, Generationinadvertently bid certain generating units into the PJM energy market at prices that slightly exceeded the cost-based caps to which it hadagreed. This error was a violation of the commitments made in connection with merger approvals by DOJ, FERC and the MDPSC.Generation reported the error to the DOJ, FERC and the MDPSC and committed to remedy 267Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) the impacts of its error. The MDPSC held a hearing to review the error, and accepted Generation’s proposed remediation. Subsequent closeexamination by Generation of its cost-based bids also revealed the need for some minor adjustments to the cost build up for certain of itsPJM units. Generation has coordinated with PJM to determine the impact on Generation’s revenues and the market from this error andthese adjustments, and Generation has worked with PJM to reverse the financial impacts. In November 2012, Generation reached asettlement with the DOJ regarding this matter. The final resolution did not have a material impact on Exelon’s or Generation’s results ofoperations, cash flows or financial position. Exelon was named in suits filed in the Circuit Court of Baltimore City, Maryland alleging that individual directors of Constellationbreached their fiduciary duties by entering into the proposed merger transaction and Exelon aided and abetted the individual directors’breaches. Similar suits were also filed in the United States District Court for the District of Maryland. The suits sought to enjoin aConstellation shareholder vote on the proposed merger until all material information was disclosed and sought rescission of the proposedmerger. During the third quarter of 2011, the parties to the suits reached an agreement in principle to settle the suits through additionaldisclosures to Constellation shareholders. On June 26, 2012, the court approved the settlement and entered final judgment. Accounting for the Merger Transaction The fair value of Constellation’s non-regulated business assets acquired and liabilities assumed was determined based on significantestimates and assumptions that are judgmental in nature, including projected future cash flows (including timing); discount rates reflectingrisk inherent in the future cash flows; and future market prices. There were also judgments made to determine the expected useful livesassigned to each class of assets acquired and duration of liabilities assumed. The financial statements of BGE do not include fair value adjustments for assets or liabilities subject to rate-setting provisions for BGE.BGE is subject to the rate-setting authority of FERC and the MDPSC and is accounted for pursuant to the accounting guidance for regulatedoperations. The rate-setting and cost recovery provisions currently in place for BGE provide revenue derived from costs including a return oninvestment of assets and liabilities included in rate base. Except for debt, fuel supply contracts and regulatory assets not earning a return, thefair values of BGE’s tangible and intangible assets and liabilities subject to these rate-setting provisions are assumed to approximate theircarrying values and, therefore, do not reflect any net adjustments related to these amounts. For BGE’s debt, fuel supply contracts andregulatory assets not earning a return, the difference between fair value and book value of BGE’s assets acquired and liabilities assumed isrecorded as a regulatory asset and liability at Exelon Corporate as Exelon did not apply push-down accounting to BGE. See Note 1—Significant Accounting Policies for additional information on BGE’s push-down accounting treatment. Also see Note 3—Regulatory Mattersfor additional information on BGE’s regulatory assets. The preliminary valuations performed in the first quarter of 2012 were updated in the second, third and fourth quarters of 2012, with themost significant adjustments to the preliminary valuation amounts having been made to the fair values assigned to the acquired powersupply and fuel contracts, unregulated property, plant and equipment and investments in affiliates. There were no significant adjustments tothe purchase price allocation in the first quarter of 2013 and the purchase price allocation was final as of March 31, 2013. 268Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The market approach was utilized when prices and other relevant information generatedby market transactions involving comparable transactions were available. Otherwise the income approach, which is based upon discountedprojected future cash flows associated with the underlying contracts, was utilized. The measure is based upon certain unobservable inputs,which are considered Level 3 inputs, pursuant to applicable accounting guidance. Key estimates and inputs include forecasted power and fuelprices and the discount rate. The fair value amounts are amortized over the life of the contract in relation to the present value of the underlyingcash flows as of the merger date. Amortization expense and income are recorded through purchased power and fuel expense or operatingrevenues. Exelon and Generation present separately in their Consolidated Balance Sheets the unamortized energy contract assets and liabilitiesfor these contracts. Generation’s amortization expense for the year ended December 31, 2013 amounted to $470 million. Generation’samortization expense for the period March 12, 2012 to December 31, 2012 amounted to $1,101 million. In addition, Exelon Corporate hasestablished a regulatory asset and an unamortized energy contract liability related to BGE’s power supply and fuel contracts. The powersupply and fuel contracts regulatory asset amortization was $77 million for the year ended December 31, 2013 and $116 million for theperiod March 12, 2012 to December 31, 2012. An equally offsetting amortization of the unamortized energy contract liability has beenrecorded at Exelon Corporate in the Consolidated Statement of Operations. The fair value of the Constellation trade name intangible asset was determined based on the relief from royalty method of the incomeapproach whereby fair value is determined to be the present value of the license fees avoided by owning the assets.

Key assumptions include the hypothetical royaltyrate and the discount rate. Exelon’s and Generation’s straight line amortization expense for the fair value of the Constellation trade nameintangible asset for the year ended December 31, 2013 and for the period March 12, 2012 to December 31, 2012 amounted to $26 millionand $20 million, respectively. The trade name intangible asset is included in deferred debits and other assets within Exelon’s andGeneration’s Consolidated Balance Sheets. The fair value of the retail relationships was determined based on a “multi-period excess method” of the income approach. Under thismethod, the intangible asset’s fair value is determined to be the estimated future cash flows that will be earned on the current customerbase, taking into account expected contract renewals based on customer attrition rates and costs to retain those customers. The measure isbased upon certain unobservable inputs, which are considered Level 3 inputs, pursuant to applicable accounting guidance. Key assumptionsinclude the customer attrition rate and the discount rate. The intangible assets for the fair value of the retail relationships are amortized asamortization expense on a straight line basis over the useful life of the underlying assets. Exelon’s and Generation’s straight lineamortization expense for year ended December 31, 2013 and for the period March 12, 2012 to December 31, 2012 amounted to $21 millionand $15 million, respectively. The retail relationships intangible assets are included in deferred debits and other assets within Exelon’s andGeneration’s Consolidated Balance Sheets.

Impact of Merger It is impracticable to determine the overall financial statement impact for the Constellation subsidiaries contributed down to Generationfollowing the Upstream Merger for the year ended December 31, 2012. Upon closing of the merger, the operations of these Constellationsubsidiaries were integrated into Generation’s operations and are therefore not fully distinguishable after the merger. The impact of BGE on Exelon’s Consolidated Statement of Operations and Comprehensive Income includes operating revenues of$3,065 million and $2,091 million and net income (loss) of $210 million and $(31) million during the years ended December 31, 2013 andDecember 31, 2012, respectively.

Additionally, Exelon and BGE established a regulatory asset of $6million as of December 31, 2013 for previously incurred 2012 merger and integration-related costs. During the year ended December 31, 2012, Exelon, Generation, ComEd, PECO and BGE incurred merger and integration-relatedcosts of $804 million, $340 million, $41 million, $17 million and $182 million, respectively. Of these amounts, Exelon, ComEd and BGEdeferred $58 million, $36 million and $22 million, respectively, as a regulatory asset as of December 31, 2012.

Acquisitions (Exelon and Generation) Consistent with the applicable accounting guidance, the fair value of the assets acquired and liabilities assumed was determined as ofthe acquisition date through the use of significant estimates and assumptions that are judgmental in nature. Some of the more significantestimates and assumptions used include: projected future cash flows (including the amount and timing); discount rates reflecting the riskinherent in the future cash flows; and future power and fuel market prices. Additionally, market prices based on the Market Price Referent(MPR) established by the CPUC for renewable energy resources were used in determining the fair value of the Antelope Valley assetsacquired and liabilities assumed. There were also judgments made to determine the expected useful lives assigned to each class of assetsacquired and the duration of the liabilities assumed.

For accounting purposes, this aspect of the transaction is considered to be akin to a“seller financing” arrangement. As such, Generation recorded a liability of $135 million associated with the portion of the future payments to First Solar, Inc. underthe EPC agreement to reflect Generation’s implicit amounts due First Solar, Inc. for the remainder of the value of the net assets acquired. The $135 million payableto First Solar, Inc. will be relieved as Generation makes payments for costs incurred over the project construction period. At December 31, 2012, $87 millionremained payable to First Solar, Inc. During 2013, a subsidiary of Generation paid off the remaining balance of the payable to First Solar, Inc. Wolf Hollow, LLC. On August 24, 2011, Generation completed the acquisition of all of the equity interests of Wolf Hollow, LLC (WolfHollow), a combined-cycle natural gas-fired power plant in north Texas, for a purchase price of $311 million which increased Generation’sowned capacity within the ERCOT power market by 720 MWs. The acquisition supports the Exelon commitment to low-carbon generationas part of Exelon 2020. Generation recognized an approximately $36 million non-cash bargain purchase gain (i.e., negative goodwill).

When fully operational, Antelope Valley will be one of the largest PVsolar projects in the world, with approximately 3.8 million solar panels generating enough clean, renewable electricity to power theequivalent of 75,000 average homes per year. The project has a 25-year PPA, approved by the California Public Utilities Commission, withPacific Gas & Electric Company for the full output of the plant. The acquisition supports Exelon’s commitment to renewable energy as part ofExelon 2020. Exelon expects to invest up to $650 million in equity in the project through 2014. The DOE’s Loan Programs Office issued a guaranteefor up to $646 million for a non-recourse loan from the Federal Financing Bank to support the financing of the construction of the project. SeeNote 13—Debt and Credit Agreements for additional information on the DOE loan guarantee. The pro forma impact of this acquisition would not have been material to Exelon’s or Generation’s results of operations for the yearended December 31, 2011. 5. Investment in Constellation Energy Nuclear Group, LLC (Exelon and Generation) As a result of the Constellation merger, Generation owns a 50.01% interest in CENG, a nuclear generation business. Generation’stotal equity in earnings (losses) on the investment in CENG is as follows: Year EndedDecember 31,2013 Period March 12,through December 31,2012 Equity investment income $123 $73 Amortization of basis difference in CENG (114) (172) Total equity in earnings (losses)—CENG $9 $(99) As of March 12, 2012, Generation had an initial basis difference of approximately $204 million between the initial carrying value of itsinvestment in CENG and its underlying equity in CENG. This basis difference resulted from the requirement to record the investment inCENG at fair value under purchase accounting while the underlying assets and liabilities within CENG continue to be accounted for on ahistorical cost basis. Generation is amortizing this basis difference over the respective useful lives of the assets and liabilities of CENG or asthose assets and liabilities affect the earnings of CENG. Based on tax sharing provisions contained in the operating agreement for CENG, Generation may be eligible for distributions from itsinvestment in CENG in excess of its 50.01% ownership interest. Through purchase accounting, Generation has recorded the fair value ofexpected future distributions. When these distributions are realized, Generation will record a reduction in its investment in CENG. Anydistributions in excess of Generation’s investment in CENG would be recorded in earnings. Generation has various agreements with CENG to purchase power and to provide certain services. For further information regardingthese agreements see Note 25—Related Party Transactions. 273Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) On July 29, 2013, Exelon, Generation and subsidiaries of Generation entered into a Master Agreement with EDF, EDF Inc. (EDFI) (asubsidiary of EDF) and CENG. The Master Agreement contemplates that the parties will execute a series of additional agreements at aclosing that will occur following the receipt of regulatory approvals and the satisfaction of other customary closing conditions. Exelon currentlyexpects that the closing will occur early in the second quarter of 2014. The Master Agreement requires CENG to make two pre-closing cash distributions to EDF and Generation, if CENG has cash inexcess of reserves and the amount of an outstanding credit facility are available, through one of its wholly owned subsidiaries, as owners ofthe joint venture. Generation received the first distribution of $115 million in December 2013 and recorded it as a reduction to the Investmentin CENG on Exelon’s and Generation’s Consolidated Balance Sheets. A second distribution will occur prior to the closing provided thatCENG has sufficient available cash. At the closing, Generation, CENG and subsidiaries of CENG will execute a Nuclear Operating Services Agreement (NOSA) pursuantto which Generation will operate the CENG nuclear generation fleet owned by CENG subsidiaries and provide corporate and administrativeservices for the remaining life of the CENG nuclear plants as if they were a part of the Generation nuclear fleet, subject to EDFI’s rights as amember of CENG. CENG will reimburse Generation for its direct and allocated costs for such services. The NOSA will replace the SSA. Atthe closing, Nine Mile Point Nuclear Station, a subsidiary of CENG, will also assign to Generation its obligations as Operator of Nine MilePoint Unit 2 under an operating agreement with the co-owner. In addition, at the closing the PSAA will be amended and extended until thepermanent cessation of power generation by the CENG generation plants. In addition, at closing, Generation will make a $400 million loan to CENG, bearing interest at 5.25% per annum and payable out ofspecified available cash flows of CENG and in any event, payable upon the settlement of the Put Option Agreement discussed below, if theput option is exercised, or payable upon the maturity date of the note (which will be 20 years from the closing), whichever occurs first.Immediately following receipt of the proceeds of such loan, CENG will make a $400 million special distribution to EDFI. The parties will alsoexecute a Fourth Amended and Restated Operating Agreement for CENG, pursuant to which, among other things, CENG will commit tomake preferred distributions to Generation (after repayment of the $400 million loan) quarterly out of specified available cash flows, untilGeneration has received aggregate distributions of $400 million plus a return of 8.5% per annum from the date of the special distribution toEDFI. Generation and EDFI will also enter into a Put Option Agreement at closing pursuant to which EDFI will have the option, exercisablebeginning on January 1, 2016 and thereafter until June 30, 2022, to sell its 49.99% interest in CENG to Generation for a fair market valueprice determined by agreement of the parties, or absent agreement, a third-party arbitration process. The appraisers determining fair marketvalue of EDF’s 49.99% interest in CENG under the Put Option Agreement are instructed to take into account all rights and obligations underthe CENG Operating Agreement, including Generation’s rights with respect to any unpaid aggregate preferred distributions and the relatedreturn, and the value of Generation’s rights to other distributions. The beginning of the exercise period will be accelerated if Exelon’s affiliatescease to own a majority of CENG and exercise a related right to terminate the Nuclear Operating Services Agreement. In addition, underlimited circumstances, the period for exercise of the put option may be extended for 18 months. Also at closing, Generation will execute an Indemnity Agreement pursuant to which Generation will indemnify EDF and its affiliatesagainst third-party claims that may arise from any future nuclear incident (as defined in the Price Anderson Act) in connection with the CENGnuclear plants or their operations. Exelon will guarantee Generation’s obligations under this indemnity. 274Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Currently, Exelon and Generation account for their investment in CENG under the equity method of accounting. The transfer of theoperating licenses and corresponding operational control to Exelon and Generation will result in Exelon and Generation being required toconsolidate the financial position and results of operations of CENG. When that accounting change occurs, Exelon and Generation willderecognize their equity method investment in CENG and will record all assets, liabilities and the non-controlling interest in CENG at fairvalue on Exelon and Generation’s balance sheets. Any difference between the former carrying value and newly recorded fair value at thatdate will be recognized as a gain or loss upon consolidation, which could be material to Exelon’s and Generation’s results of operations. 6. Accounts Receivable (Exelon, Generation, ComEd PECO and BGE) Accounts receivable at December 31, 2013 and 2012 included estimated unbilled revenues, representing an estimate for the unbilledamount of energy or services provided to customers, and is net of an allowance for uncollectible accounts as follows: 2013 Exelon Generation ComEd PECO BGE Unbilled customer revenues $1,151 $584 $201 $161 $205 Allowance for uncollectible accounts (272) (57) (62) (107) (46) 2012 Exelon Generation ComEd PECO BGE Unbilled customer revenues $1,094 $535 $213 $164 $182 Allowance for uncollectible accounts (293) (84) (70) (99) (40) (a)Represents unbilled portion of retail receivables estimated under Exelon’s unbilled critical accounting policy.(b)Includes the allowance for uncollectible accounts on customer and other accounts receivable.(c)Includes an allowance for uncollectible accounts of $8 million and $7 million at December 31, 2013 and 2012, respectively, related to PECO’s current installment planreceivables described below. PECO Installment Plan Receivables (Exelon and PECO). PECO enters into payment agreements with certain delinquentcustomers, primarily residential, seeking to restore their service, as required by the PAPUC. Customers with past due balances that meetcertain income criteria are provided the option to enter into an installment payment plan, some of which have terms greater than one year, torepay past due balances in addition to paying for their ongoing service on a current basis. The receivable balance for these paymentagreement receivables is recorded in accounts receivable for the current portion and other deferred debits and other assets for the noncurrentportion. The net receivable balance for installment plans with terms greater than one year was $19 million and $18 million as ofDecember 31, 2013 and 2012, respectively. The allowance for uncollectible accounts reserve methodology and assessment of the creditquality of the installment plan receivables are consistent with the customer accounts receivable methodology discussed in Note 1—Significant Accounting Policies. The allowance for uncollectible accounts balance associated with these receivables at December 31, 2013of $18 million consists of $1 million, $4 million and $13 million for low risk, medium risk and high risk segments, respectively. Theallowance for uncollectible accounts balance at December 31, 2012 of $15 million consists of $1 million, $3 million and $11 million for lowrisk, medium risk and high risk segments, respectively. The balance of the payment agreement is billed to the customer in equal monthlyinstallments over the term of the agreement. Installment receivables outstanding as of December 31, 2013 and 2012 include balances notyet presented on the customer bill, accounts currently billed and an immaterial amount of past due receivables. When a customer defaults onits payment agreement, the terms of which are defined by plan type, the entire balance of the agreement becomes due and the balance isreclassified to current customer accounts receivable and reserved for in accordance with the methodology discussed in Note 1—SignificantAccounting Policies. 275(a)(b)(c) (a)(b)(c) Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

License Renewals. Generation’s depreciation provisions are based on the estimated useful lives of its generating stations, whichassume the renewal of the licenses for all nuclear generating stations (except for Oyster Creek) and the hydroelectric generating stations. Asa result, the receipt of license renewals has no impact on the Consolidated Statements of Operations. See Note 3—Regulatory Matters foradditional information regarding license renewals. Plant Retirements Schuylkill Station and Riverside Station. On October 31, 2012, Generation notified PJM of its intention to permanently retireSchuylkill Generating Station Unit 1 by February 1, 2013, and Riverside Generating Station Unit 6 by June 1, 2014.

Riverside Unit 6 is a 115 MW peaking gas/kerosene unit that was placedin service in 1970, located in Baltimore, Maryland. On December 1, 2013, Generation notified PJM of its intention to permanently retireRiverside Generating Station Unit 4 by June 1, 2016. Riverside Unit 4 is a 74 MW intermediate gas unit that was placed in service in 1951also located in Baltimore, Maryland. The units are being retired because they are no longer economic to operate due to their age, relativelyhigh capital and operating costs and declining revenue expectations. On November 30, 2012, PJM notified Generation that it did not identifyany transmission system reliability issues associated with the proposed Schuylkill Unit 1 retirement date, and as a result, Schuylkill Unit 1was retired on January 1, 2013. On January 7, 2013 and December 23, 2013, PJM notified Generation that it did not identify anytransmission system reliability issues associated with the retirements of Riverside Units 6 and 4, respectively. The early retirements will nothave a material impact on Generation or Exelon’s results of operations, cash flows or financial position. Eddystone Station and Cromby Station. In December 2009, Exelon announced its intention to permanently retire three coal-firedgenerating units and one oil/gas-fired generating unit, effective May 31, 2011, in response to the economic outlook related to the continuedoperation of these four units. However, PJM determined that transmission reliability upgrades would be necessary to alleviate reliabilityimpacts and that those upgrades would be completed in a manner that will permit Generation’s retirement of two of the units on that date andtwo of the units subsequent to May 31, 2011. On May 31, 2011, Cromby Generating Station (Cromby) Unit 1 and Eddystone GeneratingStation (Eddystone) Unit 1 were retired. On May 27, 2011, the FERC approved a settlement providing for a reliability-must-run rate schedule,which defined compensation to be paid to Generation for continuing to operate Cromby Unit 2 and Eddystone Unit 2. The monthly fixed-costrecovery during the reliability-must-run period for Eddystone Unit 2 was approximately $6 million, and covered operating costs, plus a returnon net assets, of the two units during the reliability-must-run period. In addition, Generation was reimbursed for variable costs, includingfuel, emissions costs, chemicals, auxiliary power and for project investment costs during the reliability-must-run period. Eddystone Unit 2and Cromby Unit 2 operated under the reliability-must-run agreement from June 1, 2011 until their respective retirement dates, Cromby Unit2 on December 31, 2011 and Eddystone Unit 2 on May 31, 2012. During the years ended December 31, 2013, 2012, and 2011, Generation incurred $1 million, $11 million, and $2 million of shutdown costs reflected within Operating and maintenance expense in Exelon’s and Generation’s Consolidated Statements of Operations andComprehensive Income.

Impairment of Long-Lived Assets (Exelon and Generation) Long-Lived Assets (Exelon and Generation) Generation evaluates long-lived assets for recoverability whenever events or changes in circumstances indicate that the carryingamount may not be recoverable. In the third quarter of 2013, lower projected wind production and a decline in power prices suggested that thecarrying value of certain wind projects may be impaired. Generation concluded that the estimated undiscounted future cash flows and fairvalue of eleven wind projects, primarily located in West Texas and Minnesota, were less than their respective carrying values atSeptember 30, 2013. The fair value analysis was 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. As a result, long-lived assetsheld and used with a carrying amount of approximately $75 million were written down to their fair value of $32 million and a pre-taximpairment charge of $43 million was recorded during the third quarter in operating and maintenance expense in Exelon’s and Generation’sConsolidated Statements of Operations. Of the $43 million, $4 million was attributable to non-controlling interests for certain of the windprojects. 280(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Nuclear Uprate Program (Exelon and Generation) Generation is engaged in individual projects as part of a planned power uprate program across its nuclear fleet. When economicallyviable, the projects take advantage of new production and measurement technologies, new materials and application of expertise gained froma half-century of nuclear power operations. Based on ongoing reviews, the nuclear uprate implementation plan was adjusted during 2013 tocancel certain projects. The Measurement Uncertainty Recapture (MUR) uprate projects at the Dresden and Quad Cities nuclear stationswere cancelled as a result of the cost of additional plant modifications identified during final design work which, when combined with thencurrent market conditions, made the projects not economically viable. Additionally, the market conditions prompted Generation to cancel thepreviously deferred extended power uprate projects at the LaSalle and Limerick nuclear stations. During 2013, Generation recorded a pre-taxcharge to operating and maintenance expense and interest expense of approximately $111 million and $8 million, respectively, to accrueremaining costs and reverse the previously capitalized costs. Like-Kind Exchange Transaction (Exelon) Prior to the PECO/Unicom Merger in October 2000, UII, LLC (formerly Unicom Investments, Inc.) (UII), a wholly owned subsidiary ofExelon, entered into a like-kind exchange transaction pursuant to which approximately $1.6 billion was invested in coal-fired generatingstation leases located in Georgia and Texas with two separate entities unrelated to Exelon. The generating stations were leased back to suchentities as part of the transaction. See Note 14—Income Taxes for further information. For financial accounting purposes, the investments areaccounted for as direct financing lease investments. UII holds the leasehold interests in the generating stations in several separatebankruptcy remote, special purpose companies it directly or indirectly wholly owns. The lease agreements provide the lessees with fixedpurchase options at the end of the lease terms. If the lessees do not exercise the fixed purchase options, Exelon has the ability to require thelessees to return the leasehold interests or to arrange for a third-party to bid on a service contract for a period following the lease term. IfExelon chooses the service contract option, the leasehold interests will be returned to Exelon at the end of the term of the service contract. Inany event, Exelon will be subject to residual value risk if the lessees do not exercise the fixed purchase options. This risk is partiallymitigated by the fair value of the scheduled payments under the service contract. However, such payments are not guaranteed. Further, theterm of the service contract is less than the expected remaining useful life of the plants and, therefore, Exelon’s exposure to residual valuerisk will not be mitigated by payments under the service contract in this remaining period. In the fourth quarter of 2000, under the terms ofthe lease agreements, UII received a prepayment of $1.2 billion for all rent, which reduced the investment in the leases. There are nominimum scheduled lease payments to be received over the remaining term of the leases. Pursuant to the applicable accounting guidance, Exelon is required to review the estimated residual values of its direct financing leaseinvestments at least annually and record an impairment charge if the review indicates an other than temporary decline in the fair value of theresidual values below their carrying values. Exelon estimates the fair value of the residual values of its direct financing lease investmentsunder the income approach, which uses a discounted cash flow analysis, which takes into consideration significant unobservable inputs(Level 3) including the expected revenues to be generated and costs to be incurred to operate the plants over their remaining useful livessubsequent to the lease end dates. Significant assumptions used in estimating the fair value include fundamental energy and capacityprices, fixed and variable costs, capital expenditure requirements, discount rates, tax rates, and the estimated remaining useful lives of theplants. The estimated fair values also reflect the cash flows associated with the service contract option discussed above given that a marketparticipant would take into consideration all of the terms and conditions contained in the lease agreements. 281Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Based on the review performed in the second quarter of 2013, the estimated residual value of one of Exelon’s direct financing leasesexperienced an other than temporary decline given reduced long-term energy and capacity price expectations. As a result, Exelon recorded a$14 million pre-tax impairment charge in the second quarter of 2013, which was recorded in investments and operating and maintenanceexpense in the Consolidated Balance Sheet and the Consolidated Statement of Operations, respectively. Changes in the assumptionsdescribed above could potentially result in future impairments of Exelon’s direct financing lease investments, which could be material.Through December 31, 2013, no events have occurred that would require Exelon to review the estimated residual values of its directfinancing lease investments subsequent to the review performed in the second quarter of 2013. As of December 31, 2012, Exelon concluded that the estimated fair values of the residual values at the end of the lease terms exceededthe residual values established at the lease dates. At December 31, 2013 and December 31, 2012, the components of the net investment in long-term leases were as follows: December 31, 2013 December 31, 2012 Estimated residual value of leased assets $1,465 $1,492 Less: unearned income 767 807 Net investment in long-term leases $698 $685 9.

Intangible Assets (Exelon, Generation, ComEd and PECO) Goodwill Exelon’s and ComEd’s gross amount of goodwill, accumulated impairment losses and carrying amount of goodwill for the years endedDecember 31, 2013 and 2012 were as follows: GrossAmount AccumulatedImpairmentLosses CarryingAmount Balance, January 1, 2012 $4,608 $1,983 $2,625 Impairment losses — — — Balance, December 31, 2013 $4,608 $1,983 $2,625 (a)Reflects goodwill recorded in 2000 from the PECO/Unicom (predecessor parent company of ComEd) merger net of amortization, resolution of tax matters and other non-impairment-related changes as allowed under previous authoritative guidance. Goodwill is not amortized, but is subject to an assessment for impairment at least annually, or more frequently if events occur orcircumstances change that would more likely than not reduce the fair value of the ComEd reporting unit below its carrying amount. Underthe authoritative guidance for goodwill, a reporting unit is an operating segment or one level below an operating segment (known as acomponent) and is the level at which goodwill is tested for impairment. A component of an operating segment is a reporting unit if thecomponent constitutes a business for which discrete financial information is available and is regularly reviewed by segment management.ComEd has a single operating segment for its combined business. There is no level below this operating segment for which discretefinancial information is regularly reviewed by segment management. Therefore, ComEd’s operating segment is considered its only reportingunit. Entities assessing goodwill for impairment have the option of first performing a qualitative assessment before calculating the fair valueof the reporting unit (i.e., step one of the two-step fair value based impairment test). If an entity determines, on the basis of qualitative factors,that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step fair value based impairment test isrequired. Otherwise, no further testing is required. If an entity bypasses the qualitative assessment or performs the qualitative assessment, but determines that it is more likely than notthat its fair value is less than its carrying amount, a quantitative two-step, fair value based test is performed. The first step compares the fairvalue of the reporting unit to its carrying amount, including goodwill. If the carrying amount of the reporting unit 283(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) exceeds its fair value, the second step is performed. The second step requires an allocation of fair value to the individual assets and liabilitiesusing purchase price allocation in order to determine the implied fair value of goodwill. If the implied fair value of goodwill is less than thecarrying amount, an impairment loss is recorded as a reduction to goodwill and a charge to operating expense. Any goodwill impairmentcharge at ComEd will affect Exelon’s consolidated results of operations. ComEd’s valuation approach is based on a market participant view, pursuant to authoritative guidance for fair value measurement, andutilizes a weighted combination of a discounted cash flow analysis and a market multiples analysis. The discounted cash flow analysis relieson a single scenario reflecting “base case” or “best estimate” projected cash flows for ComEd’s business and includes an estimate ofComEd’s terminal value based on these expected cash flows using the generally accepted Gordon Dividend Growth formula, which derivesa valuation using an assumed perpetual annuity based on the entity’s residual cash flows. The discount rate is based on the generallyaccepted Capital Asset Pricing Model and represents the weighted average cost of capital of comparable companies. The market multiplesanalysis utilizes multiples of business enterprise value to earnings, before interest, taxes, depreciation and amortization (EBITDA) ofcomparable companies in estimating fair value. Significant assumptions used in estimating the fair value include discount and growth rates,utility sector market performance and transactions, projected operating and capital cash flows from ComEd’s business and the fair value ofdebt. Management performs a reconciliation of the sum of the estimated fair value of all Exelon reporting units to Exelon’s enterprise valuebased on its trading price to corroborate the results of the discounted cash flow analysis and the market multiple analysis. 2013 Goodwill Impairment Assessments. Management concluded the remeasurement of the like-kind exchange position and thecharge to ComEd’s earnings in the first quarter of 2013 triggered an interim goodwill impairment assessment and, as a result, ComEdtested its goodwill for impairment as of January 31, 2013. The first step of the interim impairment assessment comparing the estimated fairvalue of ComEd to its carrying value, including goodwill, indicated no impairment of goodwill; therefore, the second step was not required. ComEd performed a quantitative assessment as of November 1, 2013, for its 2013 annual goodwill impairment assessment. The firststep of the annual impairment assessment comparing the estimated fair value of ComEd to its carrying value, including goodwill, indicatedno impairment of goodwill; therefore, the second step was not required. In both the interim and annual assessments, the discounted cash flow analysis reflected Exelon’s indemnity to hold ComEd harmlessfrom any unfavorable impacts of the after-tax interest amounts related to the like-kind exchange position on ComEd’s equity. While neitherthe interim nor the annual assessments indicated an impairment of ComEd’s goodwill, certain assumptions used to estimate the fair valueof ComEd are highly sensitive to changes. Adverse regulatory actions, such as early termination of EIMA, or changes in significantassumptions, including discount and growth rates, utility sector market performance and transactions, projected operating and capital cashflows from ComEd’s business, and the fair value of debt could potentially result in a future impairment of ComEd’s goodwill, which could bematerial. Based on the results of the annual goodwill test performed as of November 1, 2013, the estimated fair value of ComEd would haveneeded to decrease by more than 10% for ComEd to fail the first step of the impairment test. Prior Goodwill Impairment Assessments. Management concluded that the May 2012 ICC final Order in ComEd’s 2011 formula rateproceeding triggered an interim goodwill impairment assessment and, as a result, ComEd tested its goodwill for impairment as of May 31,2012. The first step of the 284Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) interim impairment assessment comparing the estimated fair value of ComEd to its carrying value, including goodwill, indicated noimpairment of goodwill; therefore, the second step was not required. ComEd performed a qualitative assessment as of November 1, 2012,for its 2012 annual goodwill impairment assessment and determined that its fair value was not more likely than not less than its carryingvalue. Therefore, ComEd did not perform a quantitative assessment. As part of its qualitative assessment, ComEd evaluated, among otherthings, management’s best estimate of projected operating and capital cash flows for ComEd’s business (including the impacts of the May2012 Order) as well as changes in certain other market conditions, such as the discount rate and EBITDA multiples.

Theintangible asset recognized as a result of the settlement agreement is being amortized ratably over the remaining term of the City of Chicago franchise agreement,which ends in 2020. As required by the settlement, ComEd also made a payment of $2 million to a third-party on the City of Chicago’s behalf. Under the terms of theagreement with Midwest Generation, ComEd received payments of $32 million from Midwest Generation to relieve Midwest Generation’s obligation under the 1999fossil sale agreement with ComEd to build the generation facility in the City of Chicago.

The valuation of the acquired intangible assets discussed below were estimated by applying the incomeapproach, which is based upon discounted projected future cash flows associated with the respective PPAs. Key assumptions used in thevaluation of these intangible assets include forecasted power prices and discount rates. Those measures are based upon certainunobservable inputs, which are considered Level 3 inputs, pursuant to applicable accounting guidance. The intangible assets are amortizedas a decrease in operating revenue within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Incomeover the term of the underlying PPAs. Exelon Wind. The output of the acquired wind turbines has been sold under PPA contracts. The excess of the contract price of the PPAsover market prices was recognized as intangible assets at the acquisition date. Generation determined that the estimated acquisition-date fairvalue of the intangible assets was approximately $224 million, which is recorded in unamortized energy contract assets within Exelon’s andGeneration’s Consolidated Balance Sheets. The intangible assets are amortized on a straight-line basis over the period in which theassociated contract revenues are recognized. Antelope Valley. Upon completion of the development project, all of the output will be sold under a PPA with Pacific Gas & ElectricCompany. The excess of the contract price of the PPA over forecasted MPR-based market prices was recognized as an intangible asset at theacquisition date. Generation determined that the estimated acquisition-date fair value of the intangible asset was approximately $190 million,which is recorded in unamortized energy contract assets within Exelon’s and Generation’s Consolidated Balance Sheets. The fair value isamortized over the life of the contract in relation to the present value of the underlying cash flows as of the acquisition date. Renewable Energy Credits and Alternative Energy Credits (Exelon, Generation, ComEd and PECO). Exelon’s, Generation’s, ComEd’s and PECO’s other intangible assets, included in other current assets and other deferred debits andother assets on the Consolidated Balance Sheets, include RECs (Exelon, Generation and ComEd) and AECs (Exelon and PECO).Revenue for RECs that are part of a bundled power sale is recognized when the power is produced and delivered to the customer. As ofDecember 31, 2013, and 2012, PECO had current AECs of $19 million and $17 million, respectively, and noncurrent AECs of $5 millionand $9 million, respectively. As of December 31, 2013, and 2012, Generation had current RECs of $158 million and $61 million,respectively, and noncurrent RECs of $0 million and $45 million, respectively. As of December 31, 2013, and 2012, ComEd, had currentRECs of $3 million and $4 million, respectively.

The short-term liabilities included in the tables above are comprised of short-term borrowings (Level 2), short-term notes payable related to PECO’s accounts receivable agreement (Level 2), and dividends payable (Level 1). The Registrants’ carryingamounts of the short-term liabilities are representative of fair value because of the short-term nature of these instruments. See Note 13—Debt and Credit Agreements for additional information on PECO’s accounts receivable agreement. Long-Term Debt. The fair value amounts of Exelon’s taxable debt securities (Level 2) are determined by a valuation model that isbased on a conventional discounted cash flow methodology and utilizes assumptions of current market pricing curves. In order to incorporatethe credit risk of the Registrants into the discount rates, Exelon obtains pricing (i.e., U.S. Treasury rate plus credit spread) based on trades ofexisting Exelon debt securities as well as debt securities of other issuers in the electric utility sector with similar credit ratings in both theprimary and secondary market, across the Registrants’ debt maturity spectrum. The credit spreads of various tenors obtained from thisinformation are added to the appropriate benchmark U.S. Treasury rates in order to determine the current market yields for the varioustenors. The yields are then converted into discount rates of various tenors that are used for discounting the respective cash flows of the sametenor for each bond or note. The fair value of Generation’s non-government-backed fixed rate project financing debt (Level 3) is based on market and quoted pricesfor its own and other project financing debt with similar risk profiles. Given the low trading volume in the project financing debt market, theprice quotes used to determine fair value will reflect certain qualitative factors, such as market conditions, investor demand, newdevelopments that might significantly impact the project cash flows or off-taker credit, and other circumstances related to the project (e.g.,political and regulatory environment). The fair value of Generation’s government-back fixed rate project financing debt (Level 3) is largelybased on a discounted cash flow methodology that is similar to the taxable debt securities methodology described above. Due to the lack ofmarket trading data on similar debt, the discount rates are derived based on the original loan interest rate spread to the applicable Treasuryrate as well as a current market curve derived from government-backed securities. Variable rate project financing debt resets on a quarterlybasis and the carrying value approximates fair value. The Registrants also have tax-exempt debt (Level 3). Due to low trading volume in this market, qualitative factors, such as marketconditions, investor demand, and circumstances related to the issuer (i.e., political and regulatory environment), may be incorporated into thecredit spreads that are used to obtain the fair value as described above. SNF Obligation. The carrying amount of Generation’s SNF obligation (Level 2) is derived from a contract with the DOE to provide fordisposal of SNF from Generation’s nuclear generating stations. When determining the fair value of the obligation, the future carrying amountof the SNF obligation 288Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) estimated to be settled in 2025 is calculated by compounding the current book value of the SNF obligation at the 13-week Treasury rate. Thecompounded obligation amount is discounted back to present value using Generation’s discount rate, which is calculated using the samemethodology as described above for the taxable debt securities, and an estimated maturity date of 2025. Long-Term Debt to Financing Trusts. Exelon’s long-term debt to financing trusts is valued based on publicly traded securities issuedby the financing trusts. Due to low trading volume of these securities, qualitative factors, such as market conditions, investor demand, andcircumstances related to each issue, this debt is classified as Level 3. Preferred Securities. The fair value of these securities is determined based on the last closing price prior to quarter end, less accruedinterest. The securities are registered with the SEC and are public. PECO redeemed all outstanding series of preferred securities on May 1,2013. See Note 20—Earnings Per Share and Equity for additional information. Recurring Fair Value Measurements Exelon records the fair value of assets and liabilities in accordance with the hierarchy established by the authoritative guidance for fairvalue measurements. 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 accessas of the reporting date. Financial assets and liabilities utilizing Level 1 inputs include active exchange-traded equity securities andfunds, certain exchange-based derivatives, and money market funds. • Level 2—inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectlyobservable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include fixedincome securities, derivatives, commingled and mutual investment funds priced at NAV per fund share and fair value hedges. • Level 3—unobservable inputs, such as internally developed pricing models or third-party valuations for the asset or liability due tolittle or no market activity for the asset or liability. Financial assets and liabilities utilizing Level 3 inputs include infrequently tradedsecurities and derivatives, and investments priced using an alternative pricing mechanism or third party valuation. 289Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Cash Equivalents (Exelon, Generation, ComEd, PECO and BGE). The Registrants’ cash equivalents include investments withmaturities of three months or less when purchased. The cash equivalents shown in the fair value tables are comprised of investments inmutual and money market funds. The fair values of the shares of these funds are based on observable market prices and, therefore, havebeen categorized in Level 1 in the fair value hierarchy. Nuclear Decommissioning Trust Fund Investments and Pledged Assets for Zion Station Decommissioning (Exelon andGeneration). The trust fund investments have been established to satisfy Generation’s nuclear decommissioning obligations as required bythe NRC. The NDT funds hold debt and equity securities directly and indirectly through commingled funds. Generation’s investment policiesplace limitations on the types and investment grade ratings of the securities that may be held by the trusts. These policies limit the trustfunds’ exposures to investments in highly illiquid markets and other alternative investments. Investments with maturities of three monthsor less when purchased, including certain short-term fixed income securities are considered cash equivalents and included in the recurringfair value measurements hierarchy as Level 1 or Level 2. With respect to individually held equity securities, the trustees obtain prices from pricing services, whose prices are obtained from directfeeds from market exchanges, which Generation is able to independently corroborate. The fair values of equity securities held directly by thetrust funds are based on quoted prices in active markets and are categorized in Level 1. Equity securities held individually are primarily tradedon the New York Stock Exchange and NASDAQ-Global Select Market, which contain only actively traded securities due to the volume tradingrequirements imposed by these exchanges. For fixed income securities, multiple prices from pricing services are obtained whenever possible, which enables cross-providervalidations in addition to checks for unusual daily movements. A primary price source is identified based on asset type, class or issue foreach security. The trustees monitor prices supplied by pricing services and may use a supplemental price source or change the primary pricesource of a given security if the portfolio managers challenge an assigned price and the trustees determine that another price source isconsidered to be preferable. Generation has obtained an understanding of how these prices are derived, including the nature andobservability of the inputs used in deriving such prices. Additionally, Generation selectively corroborates the fair values of securities bycomparison to other market-based price sources. U.S. Treasury securities are categorized as Level 1 because they trade in a highly liquid andtransparent market. The fair values of fixed income securities, excluding U.S. Treasury securities, are based on evaluated prices that reflectobservable market information, such as actual trade information or similar securities, adjusted for observable differences and are categorizedin Level 2. The fair values of private placement fixed income securities are determined using a third party valuation that contains certainsignificant unobservable inputs and are categorized in Level 3. Equity and fixed income commingled funds and fixed income mutual funds are maintained by investment companies and hold certaininvestments in accordance with a stated set of fund objectives. The fair values of fixed income commingled and mutual funds held within thetrust funds, which generally hold short-term fixed income securities and are not subject to restrictions regarding the purchase or sale ofshares, are derived from observable prices. The objectives of the remaining equity commingled funds in which Exelon and Generationinvest primarily seek to track the performance of certain equity indices by purchasing equity securities to replicate the capitalization andcharacteristics of the indices. Commingled and mutual funds are categorized in Level 2 because the fair value of the funds are based onNAVs per fund share (the unit of account), primarily derived from the quoted prices in active markets on the underlying equity securities. 305Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Middle market lending are investments in loans or managed funds which invest in private companies. Generation elected the fair valueoption for its investments in certain limited partnerships that invest in middle market lending managed funds. The fair value of these loans isdetermined using a combination of valuation models including cost models, market models, and income models. Investments in middlemarket lending are categorized as Level 3 because the fair value of these securities is based largely on inputs that are unobservable andutilize complex valuation models. Investments in middle market lending typically cannot be redeemed until maturity of the term loan. Rabbi Trust Investments (Exelon, Generation, ComEd, PECO and BGE). The Rabbi trusts were established to hold assets related todeferred compensation plans existing for certain active and retired members of Exelon’s executive management and directors. Theinvestments in the Rabbi trusts are included in investments in the Registrants’ Consolidated Balance Sheets and consist primarily ofmutual funds. These funds are maintained by investment companies and hold certain investments in accordance with a stated set of fundobjectives, which are consistent with Exelon’s overall investment strategy. Mutual funds are publicly quoted and have been categorized asLevel 1 given the clear observability of the prices. Mark-to-Market Derivatives (Exelon, Generation, and ComEd). Derivative contracts are traded in both exchange-based and non-exchange-based markets. Exchange-based derivatives that are valued using unadjusted quoted prices in active markets are categorized inLevel 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 andare obtained from sources that the Registrants believe provide the most liquid market for the commodity. The price quotations are reviewedand corroborated to ensure the prices are observable and representative of an orderly transaction between market participants. This includesconsideration of actual transaction volumes, market delivery points, bid-ask spreads and contract duration. The remainder of derivativecontracts are valued using the Black model, an industry standard option valuation model. The Black model takes into account inputs such ascontract 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 inputsare generally observable. Such instruments are categorized in Level 2. The Registrants’ derivatives are predominately at liquid trading points.For derivatives that trade in less liquid markets with limited pricing information model inputs generally would include both observable andunobservable inputs. These valuations may include an estimated basis adjustment from an illiquid trading point to a liquid trading point forwhich active price quotations are available. Such instruments are categorized in Level 3. Transfers in and out of levels are recognized as of the end of the reporting period the transfer occurred. Given derivatives categorizedwithin Level 1 are valued using exchange-based quoted prices within observable periods, transfers between Level 2 and Level 1 were notmaterial. Transfers into Level 2 from Level 3 generally occur when the contract tenure becomes more observable. Transfers into Level 3from Level 2 generally occur due to changes in market liquidity or assumptions for certain commodity contracts. Exelon may utilize fixed-to-floating interest rate swaps, which are typically designated as fair value hedges, as a means to achieve itstargeted level of variable-rate debt as a percent of total debt. In addition, the Registrants may utilize interest rate derivatives to lock in interestrate levels in anticipation of future financings. These interest rate derivatives are typically designated as cash flow hedges. Exelon determinesthe current fair value by calculating the net present value of expected payments and receipts under the swap agreement, based on anddiscounted by the market’s expectation of 306Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) future interest rates. Additional inputs to the net present value calculation may include the contract terms, counterparty credit risk and othermarket parameters. As these inputs are based on observable data and valuations of similar instruments, the interest rate swaps arecategorized in Level 2 in the fair value hierarchy. See Note 12—Derivative Financial Instruments for further discussion on mark-to-marketderivatives. Deferred Compensation Obligations (Exelon, Generation, ComEd, PECO and BGE). The Registrants’ deferred compensationplans allow participants to defer certain cash compensation into a notional investment account. The Registrants include such plans in othercurrent and noncurrent liabilities in their Consolidated Balance Sheets. The value of the Registrants’ deferred compensation obligations isbased on the market value of the participants’ notional investment accounts. The notional investments are comprised primarily of mutualfunds, which are based on observable market prices. However, since the deferred compensation obligations themselves are not exchangedin an active market, they are categorized as Level 2 in the fair value hierarchy. Additional Information Regarding Level 3 Fair Value Measurements (Exelon, Generation, ComEd) Mark-to-Market Derivatives (Exelon, Generation, ComEd). For valuations that include both observable and unobservable inputs, ifthe unobservable input is determined to be significant to the overall inputs, the entire valuation is categorized in Level 3. This includesderivatives valued using indicative price quotations whose contract tenure extends into unobservable periods. In instances where observabledata is unavailable, consideration is given to the assumptions that market participants would use in valuing the asset or liability. Thisincludes assumptions about market risks such as liquidity, volatility and contract duration. Such instruments are categorized in Level 3 asthe model inputs generally are not observable. 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 riskofficer and includes the chief financial officer, corporate controller, general counsel, treasurer, vice president of strategy, vice president of auditservices and officers representing Exelon’s business units. The RMC reports to the Exelon board of directors on the scope of the riskmanagement activities and is responsible for approving all valuation procedures at Exelon. Forward price curves for the power market utilizedby the front office to manage the portfolio are reviewed and verified by the middle office and used for financial reporting by the back office. TheRegistrants consider credit and nonperformance risk in the valuation of derivative contracts categorized in Level 2 and 3, including bothhistorical and current market data in its assessment of credit and nonperformance risk by counterparty. Due to master netting agreementsand 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 marketabilitydiscounts for margining provisions and notional size. Generation’s Level 3 balance generally consists of forward sales and purchases ofpower and natural gas, coal purchases, certain transmission congestion contracts, and project financing debt. Generation utilizes variousinputs and factors including market data and assumptions that market participants would use in pricing assets or liabilities as well asassumptions 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. 307Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) 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 illiquidlocations. All locations are reviewed and verified by risk management considering published exchange transaction prices, executed bilateraltransactions, broker quotes, and other observable or public data sources. The relevant forward commodity curve used to value each of thederivatives depends on a number of factors, including commodity type, delivery location, and delivery period. Price volatility varies bycommodity and location. When appropriate, Generation discounts future cash flows using risk free interest rates with adjustments to reflectthe credit quality of each counterparty for assets and Generation’s own credit quality for liabilities. The level of observability of a forwardcommodity price is 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 highly liquid and prices are observable for up to three years in the future. The observability period ofvolatility is generally shorter than the underlying power curve used in option valuations. The forward curve for a less liquid location isestimated by using the forward curve from the liquid location and applying a spread to represent the cost to transport the commodity to thedelivery location. This spread does not typically represent a majority of the instrument’s market price. As a result, the change in fair value isclosely tied to liquid market movements and not a change in the applied spread. The change in fair value associated with a change in thespread is generally immaterial. An average spread calculated across all Level 3 power and gas delivery locations is approximately $3.92 and$0.12 for power and natural gas, respectively. Many of the commodity derivatives are short term in nature and thus a majority of the fairvalue may be based on observable inputs even though the contract as a whole must be classified as Level 3. See ITEM 7A.—QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK for information regarding the maturity by year of theRegistrant’s mark-to-market derivative assets and liabilities. On December 17, 2010, ComEd entered into several 20-year floating to fixed energy swap contracts with unaffiliated suppliers for theprocurement of long-term renewable energy and associated RECs. See Note 12—Derivative Financial Instruments for more 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 modelingassumptions. The modeling assumptions include using natural gas heat rates to project long term forward power curves adjusted by arenewable factor that incorporates time of day and seasonality factors to reflect accurate renewable energy pricing. In addition, marketabilityreserves are applied to the positions based on the tenor and supplier risk. 308Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Increases (decreases) in the forward commodity price in isolation would result in significantly higher (lower) fair values forlong 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) thevalue for the holder of the option (writer of the option). Generally, a change in the estimate of forward commodity prices is unrelated to achange in the estimate of volatility of prices. An increase to the reserves listed above would decrease the fair value of the positions. Anincrease to the heat rate or renewable factors would increase the fair value accordingly. Generally, interrelationships exist between marketprices of natural gas and power. As such, an increase in natural gas pricing would potentially have a similar impact on forward powermarkets. Nuclear Decommissioning Trust Fund Investments and Pledged Assets for Zion Station Decommissioning (Exelon andGeneration). For middle market lending, certain corporate debt securities, and private equity investments the fair value is determined usinga combination of valuation models including cost models, market models and income models. The valuation estimates are based onvaluations of comparable companies, discounting the forecasted cash flows of the portfolio company, estimating the liquidation or collateralvalue of the portfolio company or its assets, considering offers from third parties to buy the portfolio company, its historical and projectedfinancial results, as well as other factors that may impact value. Significant judgment is required in the application of discounts or premiumsapplied to the prices of comparable companies for factors such as size, marketability, credit risk and relative performance. Because Generation relies on third-party fund managers to develop the quantitative unobservable inputs without adjustment for thevaluations of its’ Level 3 investments, quantitative information about significant unobservable inputs used in valuing these investments isnot reasonably available to Generation. This includes information regarding the sensitivity of the fair values to changes in the unobservableinputs. Generation gains an understanding of the fund managers’ inputs and assumptions used in preparing the valuations. Generationperformed procedures to assess the reasonableness of the valuations. For a sample of its’ Level 3 investments, Generation reviewedindependent valuations and reviewed the assumptions in the detailed pricing models used by the fund managers. As of December 31, 2013, Generation has outstanding commitments to invest in middle market lending, corporate debt securities, andprivate equity investments of approximately $448 million. These commitments will be funded by Generation’s existing nucleardecommissioning trust funds. 12. Derivative Financial Instruments (Exelon, Generation, ComEd, PECO and BGE) The Registrants are exposed to certain risks related to ongoing business operations. The primary risks managed by using derivativeinstruments are commodity price risk and interest rate risk. 310Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Commodity Price Risk (Exelon, Generation, ComEd, PECO and BGE) To the extent the amount of energy Exelon generates differs from the amount of energy it has contracted to sell, the Registrants areexposed to market fluctuations in the prices of electricity, fossil fuels and other commodities. The Registrants employ established policies andprocedures to manage their risks associated with market fluctuations by entering into physical and financial derivative contracts, includingswaps, futures, forwards, options and short-term and long-term commitments to purchase and sell energy and energy-related products. TheRegistrants believe these instruments, which are classified as either economic hedges or non-derivatives, mitigate exposure to fluctuationsin commodity prices. Derivative accounting guidance requires that derivative instruments be recognized as either assets or liabilities at fair value, withchanges in fair value of the derivative recognized in earnings each period. Other accounting treatments are available through special electionand designation, provided they meet specific, restrictive criteria both at the time of designation and on an ongoing basis. These alternativepermissible accounting treatments include normal purchase normal sale (NPNS), cash flow hedge, and fair value hedge. For commoditytransactions, effective with the date of merger with Constellation, Generation no longer utilizes the special election provided for by the cashflow hedge designation and de-designated all of its existing cash flow hedges prior to the merger. Because the underlying forecastedtransactions remain at least reasonably possible, the fair value of the effective portion of these cash flow hedges was frozen in accumulatedOCI and reclassified to results of operations when the forecasted purchase or sale of the energy commodity occurs, or becomes probable ofnot occurring. None of Constellation’s designated cash flow hedges for commodity transactions prior to the merger were re-designated ascash flow hedges. The effect of this decision is that all derivative economic hedges for commodities are recorded at fair value throughearnings for the combined company, referred to as economic hedges in the following tables. The Registrants have applied the NPNS scopeexception to certain derivative contracts for the forward sale of generation, power procurement agreements, and natural gas supplyagreements. Non-derivative contracts for access to additional generation and certain sales to load-serving entities are accounted for primarilyunder the accrual method of accounting, which is further discussed in Note 22—Commitments and Contingencies. Additionally, Generationis exposed to certain market risks through its proprietary trading activities. The proprietary trading activities are a complement to Generation’senergy marketing portfolio but represent a small portion of Generation’s overall energy marketing activities. Economic Hedging. The Registrants are exposed to commodity price risk primarily relating to changes in the market price of electricity,fossil fuels, and other commodities associated with price movements resulting from changes in supply and demand, fuel costs, marketliquidity, weather conditions, governmental regulatory and environmental policies, and other factors. Within Exelon, Generation has themost exposure to commodity price risk. Generation uses a variety of derivative and non-derivative instruments to manage the commodityprice risk of its electric generation facilities, including power sales, fuel and energy purchases, natural gas transportation and pipeline capacityagreements and other energy-related products marketed and purchased. In order to manage these risks, Generation may enter into fixed-price derivative or non-derivative contracts to hedge the variability in future cash flows from forecasted sales of energy and purchases of fueland energy. The objectives for entering into such hedges include fixing the price for a portion of anticipated future electricity sales at a levelthat provides an acceptable return on electric generation operations, fixing the price of a portion of anticipated fuel purchases for the operationof power plants, and fixing the price for a portion of anticipated energy purchases to supply load-serving customers. The portion of forecastedtransactions hedged may vary based upon management’s policies and hedging objectives, the market, weather conditions, operational andother factors. Generation is also exposed to 311Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) differences between the locational settlement prices of certain economic hedges and the hedged generating units. This price difference isactively managed through other instruments which include derivative congestion products, whose changes in fair value are recognized inearnings each period, and auction revenue rights, which are accounted for on an accrual basis. In general, increases and decreases in forward market prices have a positive and negative impact, respectively, on Generation’s ownedand contracted generation positions that have not been hedged. Generation hedges commodity price risk on a ratable basis over three-yearperiods. As of December 31, 2013, the percentage of expected generation hedged for the major reportable segments was 92%-95%, 62%-65% and 30%-33% for 2014, 2015, and 2016, respectively. The percentage of expected generation hedged is the amount of equivalent salesdivided by the expected generation. Expected generation represents the amount of energy estimated to be generated or purchased throughowned or contracted capacity. Equivalent sales represent all hedging products, which include economic hedges and certain non-derivativecontracts, including Generation’s sales to ComEd, PECO and BGE to serve their retail load. In order to fulfill a requirement of the Illinois Settlement Legislation, Generation and ComEd entered into a five-year financial swapcontract that expired May 31, 2013. The financial swap was designed to hedge spot market purchases, which, along with ComEd’sremaining energy procurement contracts, met its load service requirements. The terms of the financial swap contract required Generation topay the around-the-clock market price for a portion of ComEd’s electricity supply requirement, while ComEd paid a fixed price. As the contract expired May 31, 2013, all realized impacts have been included in Generation’s and ComEd’s results of operations. InExelon’s consolidated financial statements, all financial statement effects of the financial swap recorded by Generation and ComEd areeliminated. In addition, the physical contracts that Generation has entered into with ComEd and that ComEd has entered into with Generation andother suppliers as part of the ComEd power procurement process, which are further discussed in Note 3—Regulatory Matters, qualify andare accounted for under the NPNS exception. Based on the Illinois Settlement Legislation and ICC-approved procurement methodologiespermitting ComEd to recover its electricity procurement costs from retail customers with no mark-up, ComEd’s price risk related to powerprocurement is limited. On December 17, 2010, ComEd entered into several 20-year floating-to-fixed energy swap contracts with unaffiliated suppliers for theprocurement of long-term renewable energy and associated RECs. Delivery under the contracts began in June 2012. Pursuant to the ICC’sOrder on December 19, 2012, ComEd’s commitments under the existing long-term contracts for energy and associated RECs were reducedin the first quarter of 2013. These contracts are designed to lock in a portion of the long-term commodity price risk resulting from therenewable energy resource procurement requirements in the Illinois Settlement Legislation. ComEd has not elected hedge accounting forthese derivative financial instruments. ComEd records the fair value of the swap contracts on its balance sheet. Because ComEd receives fullcost recovery for energy procurement and related costs from retail customers, the change in fair value each period is recorded by ComEd as aregulatory asset or liability. See Note 3—Regulatory Matters for additional information. PECO has contracts to procure electric supply that were executed through the competitive procurement process outlined in its PAPUC-approved DSP Programs, which are further discussed in Note 3—Regulatory Matters. Based on Pennsylvania legislation and the DSPPrograms permitting 312Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) PECO to recover its electric supply procurement costs from retail customers with no mark-up, PECO’s price risk related to electric supplyprocurement is limited. PECO locked in fixed prices for a significant portion of its commodity price risk through full requirements contractsand block contracts. PECO has certain full requirements contracts and block contracts, that are considered derivatives and qualify for theNPNS scope exception under current derivative authoritative guidance. PECO’s natural gas procurement policy is designed to achieve a reasonable balance of long-term and short-term gas purchases underdifferent pricing approaches in order to achieve system supply reliability at the least cost. PECO’s reliability strategy is two-fold. First, PECOmust assure that there is sufficient transportation capacity to satisfy delivery requirements. Second, PECO must ensure that a firm source ofsupply exists to utilize the capacity resources. All of PECO’s natural gas supply and asset management agreements that are derivativeseither qualify for the NPNS scope exception and have been designated as such, or have no mark-to-market balances because the derivativesare index priced. Additionally, in accordance with the 2013 PAPUC PGC settlement and to reduce the exposure of PECO and its customersto natural gas price volatility, PECO has continued its program to purchase natural gas for both winter and summer supplies using a layeredapproach of locking-in prices ahead of each season with long-term gas purchase agreements (those with primary terms of at least twelvemonths). Under the terms of the 2013 PGC settlement, PECO is required to lock in (i.e., economically hedge) the price of a minimumvolume of its long-term gas commodity purchases. PECO’s gas-hedging program is designed to cover about 30% of planned natural gaspurchases in support of projected firm sales. The hedging program for natural gas procurement has no direct impact on PECO’s financialposition or results of operations as natural gas costs are fully recovered from customers under the PGC. BGE has contracts to procure SOS electric supply that are executed through a competitive procurement process approved by theMDPSC. The SOS rates charged recover BGE’s wholesale power supply costs and include an administrative fee. The administrative feeincludes an incremental cost component and a shareholder return component for commercial and industrial rate classes. BGE’s price riskrelated to electric supply procurement is limited. BGE locks in fixed prices for all of its SOS requirements through full requirements contracts.Certain of BGE’s full requirements contracts, which are considered derivatives, qualify for the NPNS scope exception under currentderivative authoritative guidance. Other BGE full requirements contracts are not derivatives. BGE provides natural gas to its customers under a MBR mechanism approved by the MDPSC. Under this mechanism, BGE’s actualcost of gas is compared to a market index (a measure of the market price of gas in a given period). The difference between BGE’s actual costand the market index is shared equally between shareholders and customers. BGE must also secure fixed price contracts for at least 10%,but not more than 20%, of forecasted system supply requirements for flowing (i.e., non-storage) gas for the November through March period.These fixed-price contracts are not subject to sharing under the MBR mechanism. BGE also ensures it has sufficient pipeline transportationcapacity to meet customer requirements. All of BGE’s natural gas supply and asset management agreements qualify for the NPNS scopeexception and result in physical delivery. Proprietary Trading. Generation also enters into certain energy-related derivatives for proprietary trading purposes. Proprietary tradingincludes all contracts entered into with the intent of benefiting from shifts or changes in market prices as opposed to those entered into withthe intent of hedging or managing risk. Proprietary trading activities are subject to limits established by Exelon’s RMC. The proprietarytrading activities, which included settled physical sales volumes of 8,762 GWh, 12,958 GWh and 5,742 Gwh for the years endedDecember 31, 2013, 2012 and 2011, are a complement to 313Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

ComEd,PECO and BGE do not enter into derivatives for proprietary trading purposes. Interest Rate and Foreign Exchange Risk (Exelon, Generation, ComEd, PECO and BGE) The Registrants use a combination of fixed-rate and variable-rate debt to manage interest rate exposure. The Registrants may alsoutilize fixed-to-floating interest rate swaps, which are typically designated as fair value hedges, as a means to manage their interest rateexposure. In addition, the Registrants may utilize interest rate derivatives to lock in rate levels in anticipation of future financings, which aretypically designated as cash flow hedges. These strategies are employed to manage interest rate risks. At December 31, 2013, Exelon had$1,425 million of notional amounts of fixed-to-floating hedges outstanding and $190 million of notional amounts of floating-to-fixed hedgesoutstanding. Assuming the fair value and cash flow interest rate hedges are 100% effective, a hypothetical 50 bps increase in the interestrates associated with unhedged variable-rate debt (excluding Commercial Paper) and fixed-to-floating swaps would result in an approximate$5 million decrease in Exelon Consolidated pre-tax income for the year ended December 31, 2013. To manage foreign exchange rateexposure associated with international energy purchases in currencies other than U.S. dollars, Generation utilizes foreign currencyderivatives, which are typically designated as economic hedges. Below is a summary of the interest rate and foreign currency hedges as ofDecember 31, 2013.

Fair Value Hedges. For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivativeas well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. Exelon includes thegain or loss on the hedged items and the offsetting loss or gain on the related interest rate swaps in interest expense as follows: Twelve Months Ended December 31, Income Statement Location 2013 2012 2011 2013 2012 2011 Gain (Loss) on Swaps Gain (Loss) on Borrowings Generation Interest expense $(15) $(6) $— $— $(6) $— Exelon Interest expense $(24) $(9) $1 $11 $(3) $(1) (a)For the years ended December 31, 2013 and 2012, the loss on Generation swaps included $16 million and $12 realized in earnings, respectively, with $2 million andan immaterial amount excluded from hedge effectiveness testing, respectively. During the third and fourth quarters of 2013, Exelon entered into $625 million of notional amounts of fixed-to-floating fair value hedgesrelated to interest rate swaps, which expire in 2020. At December 31, 2013, Exelon and Generation had total outstanding fixed-to-floating fairvalue hedges related to interest rate swaps of $1,275 million and $550 million, with unrealized gains of $26 million and $23 million,respectively. At December 31, 2012, Exelon and Generation had outstanding fixed-to-floating fair value hedges related to interest rate swapsof $650 million and $550 million that expire in 2015, with unrealized gains of $49 million and $38 million, respectively. During the yearsended December 31, 2013 and 2012, the impact on the results of operations as a result of ineffectiveness from fair value hedges was a $2million gain and immaterial, respectively. 315(a)(b) (a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Cash Flow Hedges. In anticipation of the Continental Wind, LLC non-recourse project financing that was completed on September 30,2013, Exelon entered into forward-starting interest rate swaps that were designated as cash flow hedges to hedge the change in benchmarkinterest rates. Upon settlement of the swaps, a $26 million effective gain in OCI was deferred and will be amortized into interest expenseover the life of the debt. See Note 13—Debt and Credit Agreements for additional information on the project financing. In connection with the DOE guaranteed loan for the Antelope Valley acquisition, as discussed in Note 13—Debt and CreditAgreements, Generation entered into a floating-to-fixed forward starting interest rate swap with a notional amount of $485 million and amandatory early termination date of April 5, 2014. The swap hedges approximately 75% of Generation’s future interest rate exposureassociated with the financing and was designated as a cash flow hedge. As such, the effective portion of the hedge is recorded in othercomprehensive income within Generation’s Consolidated Balance Sheets, with any ineffectiveness recorded in Generation’s ConsolidatedStatements of Operations and Comprehensive Income. Net gains (or losses) from settlement of the hedges, to the extent effective, areamortized as an adjustment to the interest expense over the term of the DOE guaranteed loan. Every time Generation draws down on the loan, an offsetting hedge (fixed-to-floating) is executed and a portion of the cash flow hedgewith a notional amount equal to the offsetting hedge, is de-designated and the related gains or losses going forward are reflected in earnings,which are largely offset by the losses or gains in the offsetting hedge. Antelope Valley received its first loan advance on April 5, 2012, and a series of additional advances subsequently. Generation hasentered into a series of fixed-to-floating interest rate swaps with an aggregated notional amount of $350 million, approximately 75% of theloan advance amount to offset portions of the original interest rate hedge, which are not designated as cash flow hedges. The remaining cashflow hedge has a notional amount of $135 million. At December 31, 2013, Generation’s mark-to-market non-current derivative liabilityrelating to the interest rate swaps in connection with the loan agreement to fund Antelope Valley was $10 million. During the third quarter of 2011, a subsidiary of Constellation entered into floating-to-fixed interest rate swaps to manage a portion of theinterest rate exposure for anticipated long-term borrowings to finance Sacramento PV Energy. The swaps have a total notional amount of $28million as of December 31, 2013 and expire in 2027. After the closing of the merger with Constellation, the swaps were re-designated ascash flow hedges. At December 31, 2013, the subsidiary had a $1 million derivative liability related to these swaps. During the third quarter of 2012, a subsidiary of Exelon Generation entered into a floating-to-fixed interest rate swap to manage aportion of the interest rate exposure of anticipated long-term borrowings to finance Constellation Solar Horizons. The swap has a notionalamount of $27 million as of December 31, 2013, and expires in 2030. This swap is designated as a cash flow hedge. At December 31,2013, the subsidiary had a $2 million derivative asset related to the swap. During the years ended December 31, 2013, and 2012, the impact on the results of operations as a result of ineffectiveness from cashflow hedges was immaterial. Economic Hedges.

At December 31, 2013, Exelon and Generation had $150 million in notional amounts of fixed-to-floating interest rate swaps that aremarked-to-market, with unrealized gains of $2 million. These swaps, which were acquired as part of the merger with Constellation, expire in2014. During the year ended December 31, 2013, and the period from March 12 to December 31, 2012, the impact on the results ofoperations was immaterial. Fair Value Measurement and Accounting for the Offsetting of Amounts Related to Certain Contracts (Exelon, Generation,ComEd, PECO and BGE) Fair value accounting guidance and disclosures about offsetting assets and liabilities requires the fair value of derivative instruments tobe shown in the Notes to the Consolidated Financial Statements on a gross basis, even when the derivative instruments are subject tolegally enforceable master netting agreements and qualify for net presentation in the Consolidated Balance Sheet. A master nettingagreement is an agreement between two counterparties that may have derivative and non-derivative contracts with each other providing forthe net settlement of all referencing contracts via one payment stream, which takes place either as the contracts deliver, when collateral isrequested or in the event of default. Generation’s use of cash collateral is generally unrestricted unless Generation is downgraded belowinvestment grade (i.e. to BB+ or Ba1). In the table below, Generation’s energy-related economic hedges and proprietary trading derivativesare shown gross and the impact of the netting of fair value balances with the same counterparty that are subject to legally enforceable masternetting agreements, as well as netting of cash collateral, is aggregated in the collateral and netting column. As of December 31, 2013 and2012, $10 million of cash collateral posted and $3 million of cash collateral received, respectively, was not offset against derivative positionsbecause such collateral was not associated with any energy-related derivatives or as of the balance sheet date there were no positions tooffset. Excluded from the tables below are economic hedges that qualify for the NPNS scope exception and other non-derivative contracts thatare accounted for under the accrual method of accounting. ComEd’s use of cash collateral is generally unrestricted unless ComEd is downgraded below investment grade (i.e. to BB+ or Ba1). Cash collateral held by PECO and BGE must be deposited in a non affiliate major U.S. commercial bank or foreign bank with a U.S.branch office that meet certain qualifications. 317Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

These amounts include unrealizedderivative transactions with the same counterparty under legally enforceable master netting agreements and cash collateral. In some cases Exelon and Generationmay have other offsetting exposures, subject to a master netting or similar agreement, such as trade receivables and payables, transactions that do not qualify asderivatives, and letters of credit. These are not reflected in the table above.(c)Current and noncurrent assets are shown net of collateral of $113 million and $201 million, respectively, and current and noncurrent liabilities are shown net ofcollateral of $ (214) million and $ (131) million, respectively.

Cash Flow Hedges (Exelon, Generation and ComEd). As discussed previously, effective prior to the merger with Constellation,Generation de-designated all of its cash flow hedges relating to commodity price risk. Because the underlying forecasted transactions remainat least reasonably possible, the fair value of the effective portion of these cash flow hedges was frozen in accumulated OCI and isreclassified to results of operations when the forecasted purchase or sale of the energy commodity occurs, or becomes probable of notoccurring.

Approximately $195 million of thesenet pre-tax unrealized gains within accumulated OCI are expected to be reclassified from accumulated OCI during the next twelve months byGeneration. Generation expects the settlement of the majority of its cash flow hedges will occur during 2013 through 2014. Exelon discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the cashflows of a hedged item or when it is no longer probable that the forecasted transaction will occur. For the year ended 2012, the amountreclassified into earnings as a result of the discontinuance of cash flow hedges was immaterial. The tables below provide the activity of accumulated OCI related to cash flow hedges for the years ended December 31, 2013 and 2012,containing information about the changes in the fair value of cash flow hedges and the reclassification from accumulated OCI into results ofoperations. The amounts reclassified from accumulated OCI, when combined with the impacts of the actual physical power sales, result inthe ultimate recognition of net revenues at the contracted price.

Changes in cash flowhedge ineffectiveness were losses of $5 million and a gain of $10 million for the years ended 2012 and 2011, respectively. Exelon’s former energy-related cash flow hedge activity impact to pre-tax earnings based on the reclassification adjustment fromaccumulated OCI to earnings was a $464 million, $747 million and $512 million pre-tax gain for the years ended December 31, 2013, 2012and 2011, respectively.

Economic Hedges (Exelon and Generation). These instruments represent hedges that economically mitigate exposure tofluctuations in commodity prices and include financial options, futures, swaps, physical forward sales and purchases, but for which the fairvalue or cash flow hedge elections were not made. Additionally, Generation enters into interest rate derivative contracts and foreign exchangecurrency swaps to manage the exposure related to the interest rate component of commodity positions and international purchases ofcommodities in currencies other than U.S. Dollars. For the years ended December 31, 2013, 2012 and 2011, the following net pre-tax mark-to-market gains (losses) of certain purchase and sale contracts were reported in operating revenues or purchased power and fuel expense atExelon and Generation in the Consolidated Statements of Operations and Comprehensive Income and are included in “Net fair valuechanges related to derivatives” in Exelon’s and Generation’s Consolidated Statements of Cash Flows.

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 creditlimits are based on an internal credit review process that considers a variety of factors, including the results of a scoring model, leverage,liquidity, profitability, credit ratings by credit rating agencies, and risk management capabilities. To the extent that a counterparty’s marginingthresholds 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 andan aggregate basis. The following tables provide information on Generation’s credit exposure for all derivative instruments, NPNS, and applicable payablesand receivables, net of collateral and instruments that are subject to master netting agreements, as of December 31, 2013.

If the forward market price of energy exceeds the benchmark price, the suppliers are required to postcollateral for the secured credit portion after adjusting for any unpaid deliveries and unsecured credit allowed under the contract. Theunsecured credit used by the suppliers represents ComEd’s net credit exposure. As of December 31, 2013, ComEd’s credit exposure tosuppliers was immaterial. ComEd is permitted to recover its costs of procuring energy through the Illinois Settlement Legislation. ComEd’s counterparty creditrisk is mitigated by its ability to recover realized energy costs through customer rates. See Note 3—Regulatory Matters for additionalinformation. PECO’s supplier master agreements that govern the terms of its electric supply procurement contracts, which define a supplier’sperformance assurance requirements, allow a supplier to meet its credit requirements with a certain amount of unsecured credit. Theamount of unsecured credit is determined based on the supplier’s lowest credit rating from the major credit rating agencies and the supplier’stangible net worth. The credit position is based on the initial market price, which is the forward price of energy on the day a transaction isexecuted, compared to the current forward price curve for energy. To the extent that the forward price curve for energy exceeds the initialmarket price, the supplier is required to post collateral to the extent the credit exposure is greater than the supplier’s unsecured credit limit.The unsecured credit used by the suppliers represents PECO’s net credit exposure. As of December 31, 2013, PECO had no net creditexposure with suppliers. PECO is permitted to recover its costs of procuring electric supply through its PAPUC-approved DSP Program. PECO’s counterpartycredit risk is mitigated by its ability to recover realized energy costs through customer rates. See Note 3—Regulatory Matters for additionalinformation. PECO’s natural gas procurement plan is reviewed and approved annually on a prospective basis by the PAPUC. PECO’s counterpartycredit risk under its natural gas supply and asset management agreements is mitigated by its ability to recover its natural gas costs throughthe PGC, which allows PECO to adjust rates quarterly to reflect realized natural gas prices. PECO does not obtain collateral from suppliersunder its natural gas supply and asset management agreements. As of December 31, 2013, PECO had credit exposure of $9 million underits natural gas supply and asset management agreements with investment grade suppliers. BGE is permitted to recover its costs of procuring energy through the MDPSC-approved procurement tariffs. BGE’s counterparty creditrisk is mitigated by its ability to recover realized energy costs through customer rates. See Note 3—Regulatory Matters for additionalinformation. BGE’s full requirement wholesale electric power agreements that govern the terms of its electric supply procurement contracts, whichdefine a supplier’s performance assurance requirements, allow a supplier, or its guarantor, to meet its credit requirements with a certainamount of unsecured credit. The amount of unsecured credit is determined based on the supplier’s lowest credit rating from the major creditrating agencies and the supplier’s tangible net worth, subject to an unsecured credit cap. The credit position is based on the initial marketprice, which is the forward price of energy on the day a transaction is executed, compared to the current forward price curve for energy. To theextent that the forward price curve for energy exceeds the initial market price, the supplier is required to post collateral to the extent the creditexposure is greater than the supplier’s unsecured credit limit. The unsecured credit used by the suppliers represents BGE’s net creditexposure. The seller’s credit exposure is calculated each business day. As of December 31, 2013, BGE had no net credit exposure tosuppliers. 324Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) BGE’s regulated gas business is exposed to market-price risk. This market-price risk is mitigated by BGE’s recovery of its costs toprocure natural gas through a gas cost adjustment clause approved by the MDPSC. BGE does make off-system sales after BGE hassatisfied its customers’ demands, which are not covered by the gas cost adjustment clause. At December 31, 2013, BGE had credit exposureof $14 million related to off-system sales which is mitigated by parental guarantees, letters of credit, or right to offset clauses within othercontracts with those third-party suppliers. Collateral and Contingent-Related Features (Exelon, Generation, ComEd, PECO and BGE) As part of the normal course of business, Generation routinely enters into physical or financially settled contracts for the purchase andsale of electric capacity, energy, fuels, emissions allowances and other energy-related products. Certain of Generation’s derivativeinstruments contain provisions that require Generation to post collateral. Generation also enters into commodity transactions on exchanges(i.e. NYMEX, ICE). The exchanges act as the counterparty to each trade. Transactions on the exchanges must adhere to comprehensivecollateral and margining requirements. This collateral may be posted in the form of cash or credit support with thresholds contingent uponGeneration’s credit rating from each of the major credit rating agencies. The collateral and credit support requirements vary by contract and bycounterparty. These credit-risk-related contingent features stipulate that if Generation were to be downgraded or lose its investment gradecredit rating (based on its senior unsecured debt rating), it would be required to provide additional collateral. This incremental collateralrequirement allows for the offsetting of derivative instruments that are assets with the same counterparty, where the contractual right of offsetexists under applicable master netting agreements. In the absence of expressly agreed-to provisions that specify the collateral that must beprovided, 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 thebest 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 fullycollateralized (excluding transactions on the exchanges that are fully collateralized) is detailed in the table below: For the Years Ended December 31, Credit-Risk Related Contingent Feature 2013 2012 Gross Fair Value of Derivative Contracts Containing this Feature $(1,056) $(1,849) Offsetting Fair Value of In-the-Money Contracts Under Master Netting Arrangements $846 $1,426 Net Fair Value of Derivative Contracts Containing This Feature $(210) $(423) (a)Amount represents the gross fair value of out-of-the-money derivative contracts containing credit-risk-related contingent ignoring the effects of master nettingagreements.(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 ofoffsetting positions under master netting arrangements and reflects the actual net liability upon which any potential contingent collateral obligations would be based.

In the event of a credit downgrade below investment grade (i.e. BB+ or Ba1), Generation could berequired to post additional collateral of $2.0 billion as of December 31, 2013 and December 31, 2012. These amounts represent the potentialadditional collateral required after giving consideration to offsetting derivative and non-derivative positions under master netting agreements. Generation’s and Exelon’s interest rate swaps contain provisions that, in the event of a merger, if Generation’s debt ratings were tomaterially weaken, it would be in violation of these provisions, resulting in the ability of the counterparty to terminate the agreement prior tomaturity. Collateralization would not be required under any circumstance. Termination of the agreement could result in a settlement paymentby Exelon or the counterparty on any interest rate swap in a net liability position. The settlement amount would be equal to the fair value ofthe swap on the termination date. As of December 31, 2013, Generation’s and Exelon’s swaps were in an asset position, with a fair value of$18 million and $21 million, respectively. See Note 24—Segment Information for additional information regarding the letters of credit supporting the cash collateral. Generation entered into supply forward contracts with certain utilities, including PECO and BGE, with one-sided collateral postingsonly 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 postcollateral once certain unsecured credit limits are exceeded. Under the terms of ComEd’s standard block energy contracts, collateral postingsare one-sided from suppliers, including Generation, should exposures between market prices and benchmark prices exceed establishedunsecured credit limits outlined in the contracts. As of December 31, 2013, ComEd held neither cash nor letters of credit for the purpose ofcollateral from suppliers in association with energy procurement contracts. Under the terms of ComEd’s annual renewable energy contracts,collateral postings are required to cover a fixed value for RECs only. In addition, under the terms of ComEd’s long-term renewable energycontracts, collateral postings are required from suppliers for both RECs and energy. The REC portion is a fixed value and the energy portionis one-sided from suppliers should the forward market prices exceed contract prices. As of December 31, 2013, ComEd held approximately$19 million in the form of cash and letters of credit as margin for both the annual and long-term REC obligations. See Note 1—SignificantAccounting Policies for additional information. PECO’s natural gas procurement contracts contain provisions that could require PECO to post collateral. This collateral may be postedin the form of cash or credit support with thresholds contingent upon PECO’s credit rating from the major credit rating agencies. Thecollateral and credit support requirements vary by contract and by counterparty. As of December 31, 2013, PECO was not required to postcollateral for any of these agreements. If PECO lost its investment grade credit rating as of December 31, 2013, PECO could have beenrequired to post approximately $42 million of collateral to its counterparties. PECO’s supplier master agreements that govern the terms of its DSP Program contracts do not contain provisions that would requirePECO to post collateral.

Credit Agreements On January 23, 2013, Generation entered into a two year $75 million bilateral letter of credit facility with a bank. The credit agreementexpires in January 2015. This facility will solely be utilized by Generation to issue letters of credit. On March 14, 2013, ComEd extended its unsecured revolving credit facility with aggregate bank commitments of $1.0 billion. Underthis facility, ComEd may issue letters of credit in the aggregate amount of up to $500 million. The credit agreement expires on March 28,2018, and ComEd may request another one-year extension of that term. The credit facility also allows ComEd to request increases in theaggregate commitments of up to an additional $500 million. Any such extension or increases are subject to the approval of the lenders partyto the credit agreement in their sole discretion. Costs incurred to extend the facility for ComEd were not material. On August 10, 2013, Exelon Corporate, Generation, PECO and BGE amended and extended their respective unsecured syndicatedrevolving credit facilities, with aggregate bank commitments of $500 million, $5.3 billion, $600 million and $600 million, respectively. Thenew covenants are substantially consistent with existing covenants. Costs incurred to amend and extend the facilities for Exelon Corporate,Generation, PECO and BGE were not material. Effective August 10, 2013, Exelon and ComEd entered into amendments to each of their respective revolving credit facilities (theAmendments). The Amendments relate to the IRS’s challenge to the position taken by Exelon on its 1999 federal income tax return withrespect to the sale of ComEd’s fossil generating assets in a like-kind exchange tax position. The Amendments are intended to exclude thenon-cash impact of the like-kind exchange tax position from the calculation of the interest coverage ratio under each of Exelon and ComEd’srespective credit facilities. See Note 12—Income Taxes for additional information. On January 27, 2014 ComEd began the process of extending its unsecured syndicated revolving credit facility, with aggregate bankcommitments of $1.0 billion. The transaction is expected to close and become effective in March 2014, with a maturity of five years from theclose of the transaction. No changes are expected to be made to the facility other than extension of the term for an additional one year period.Generally, it is expected that costs incurred to extend the facility will be amortized over the newly extended life of the facility. 329Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Borrowings under Exelon Corporate’s, Generation’s, ComEd’s, PECO’s and BGE’s credit agreements bear interest at a rate basedupon either the prime rate or a LIBOR-based rate, plus an adder based upon the particular registrant’s credit rating. Exelon Corporate,Generation, ComEd, PECO and BGE have adders of 27.5, 27.5, 27.5, 0.0 and 7.5 basis points for prime based borrowings and 127.5,127.5, 127.5, 100.0 and 107.5 basis points for LIBOR-based borrowings. The maximum adders for prime rate borrowings and LIBOR-basedrate borrowings are 65 basis points and 165 basis points, respectively. The credit agreements also require the borrower to pay a facility feebased upon the aggregate commitments under the agreement. The fee varies depending upon the respective credit ratings of the borrower. An event of default under any of the Registrants’ credit facilities would not constitute an event of default under any of the otherRegistrants’ credit facilities, except that a bankruptcy or other event of default in the payment of principal, premium or indebtedness inprincipal amount in excess of $100 million in the aggregate by Generation under its credit facility would constitute an event of default underthe Exelon Corporate credit facility. On October 18, 2013, Generation, ComEd, PECO and BGE refinanced their respective minority and community bank credit facilityagreements in the amounts of $50 million, $34 million, $34 million and $5 million, respectively. These facilities, which expire in October2014, are solely utilized to issue letters of credit. Each credit facility requires the affected borrower to maintain a minimum cash from operations to interest expense ratio for the twelve-month period ended on the last day of any quarter. The ratios exclude revenues and interest expenses attributable to securitization debt,certain changes in working capital, distributions on preferred securities of subsidiaries and, in the case of Exelon and Generation, interest onthe debt of its project subsidiaries.

The agreement terminated on August 30, 2013and PECO paid down the outstanding principal of $210 million. The financial institution no longer has an undivided interest in the accountsreceivable designated under the agreement. As of December 31, 2012, the financial institution’s undivided interest in Exelon’s and PECO’sgross accounts receivable was equivalent to $289 million, which represented the financial institution’s interest in PECO’s eligiblereceivables as calculated under the terms of the agreement. The agreement required PECO to maintain eligible receivables at leastequivalent to the financial institution’s undivided interest. 330Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The disallowance of such positions would not materially affect the annual effective tax rate but would accelerate the payment ofcash to, or defer the receipt of the cash tax benefit from, the taxing authority to an earlier or later period respectively. Unrecognized tax benefits that if recognized would affect the effective tax rate Exelon and Generation have $788 million and $768 million, respectively, of unrecognized tax benefits at December 31, 2013 that, ifrecognized, would decrease the effective tax rate. Exelon and Generation had $294 million and $263 million, respectively, of unrecognizedtax benefits at December 31, 2012 that, if recognized, would decrease the effective tax rate. Reasonably possible that total amount of unrecognized tax benefits could significantly increase or decrease within 12months after the reporting date Nuclear Decommissioning Liabilities (Exelon and Generation) AmerGen filed income tax refund claims taking the position that nuclear decommissioning liabilities assumed as part of its acquisitionof nuclear power plants are taken into account in determining the tax basis in the assets it acquired. The additional basis results primarily inreduced capital gains or increased capital losses on the sale of assets in nonqualified decommissioning funds and increased tax depreciationand amortization deductions. The IRS disagrees with this position and has disallowed the claims. In November 2008, Generation received afinal determination from the Appeals division of the IRS (IRS Appeals) disallowing AmerGen’s refund claims. Generation filed a complaint inthe United States Court of Federal Claims on February 20, 2009 to contest this determination. During the first and second quarters of 2013,AmerGen and the DOJ completed and filed cross motions for summary judgment. On September 17, 2013, the Court granted thegovernment’s motion denying AmerGen’s claims for refund. Exelon is expecting to appeal this decision to the United States Court of Appealsfor the Federal Circuit during 2014. Due to the possibility of final resolution through an appellate decision, Generation continues to believe that it is reasonably possible thatthe total amount of unrecognized tax benefits will significantly decrease in the next twelve months. Settlement of Income Tax Audits and Litigation As of December 31, 2013, Exelon and Generation had approximately $256 million of other federal and state unrecognized tax benefitsthat could significantly increase or decrease within the 12 months 340Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The gain was deferred by reinvesting the proceeds from the sale in qualifying replacementproperty under the like-kind exchange provisions of the IRC. The like-kind exchange replacement property purchased by 341Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Exelon included interests in three municipal-owned electric generation facilities which were properly leased back to the municipalities. TheIRS disagreed with this position and asserted that the entire gain of approximately $2.8 billion was taxable in 1999. Exelon has been unable to reach agreement with the IRS regarding the dispute over the like kind exchange position. The IRS hasasserted that the Exelon purchase and leaseback transaction is substantially similar to a leasing transaction, known as a SILO, which theIRS does not respect as the acquisition of an ownership interest in property. A SILO is a “listed transaction” that the IRS has identified as apotentially abusive tax shelter under guidance issued in 2005. Accordingly, the IRS has asserted that the sale of the fossil plants followed bythe purchase and leaseback of the municipal owned generation facilities does not qualify as a like-kind exchange and the gain on the sale isfully subject to tax. The IRS has also asserted a penalty of approximately $87 million for a substantial understatement of tax. Exelon disagrees with the IRS and continues to believe that its like-kind exchange transaction is not the same as or substantiallysimilar to a SILO. Although Exelon has been and remains willing to settle the disagreement on terms commensurate with the hazards oflitigation, Exelon does not believe a settlement is possible. Because Exelon believed, as of December 31, 2012, that it was more-likely-than-not that Exelon would prevail in litigation, Exelon and ComEd had no liability for unrecognized tax benefits with respect to the like-kindexchange position. On January 9, 2013, the U.S. Court of Appeals for the Federal Circuit reversed the U.S. Court of Federal Claims and reached adecision for the government in Consolidated Edison v. United States. The Court disallowed Consolidated Edison’s deductions stemmingfrom its participation in a LILO transaction that the IRS also has characterized as a tax shelter. In accordance with applicable accounting standards, Exelon is required to assess whether it is more-likely-than-not that it will prevail inlitigation. Exelon continues to believe that its transaction is not a SILO and that it has a strong case on the merits. However, in light of theConsolidated Edison decision and Exelon’s current determination that settlement is unlikely, Exelon has concluded that subsequent toDecember 31, 2012, it is no longer more-likely-than-not that its position will be sustained. As a result, in the first quarter of 2013, Exelonrecorded a non-cash charge to earnings of approximately $265 million, which represents the amount of interest expense (after-tax) andincremental state income tax expense for periods through March 31, 2013 that would be payable in the event that Exelon is unsuccessful inlitigation. Of this amount, approximately $170 million was recorded at ComEd. Exelon intends to hold ComEd harmless from anyunfavorable impacts of the after-tax interest amounts on ComEd’s equity. As such, ComEd recorded on its consolidated balance sheet as ofMarch 31, 2013, a $172 million receivable and non-cash equity contributions from Exelon. Exelon and ComEd will continue to accrueinterest on the uncertain tax position, and the charges arising from future interest accruals are not expected to be material to the annualoperating earnings of Exelon or ComEd. In addition ComEd will continue to record non-cash equity contributions from Exelon in the amountof the net after-tax interest charges attributable to ComEd in connection with the like-kind exchange position. Exelon continues to believe thatit is unlikely that the $87 million penalty assertion will ultimately be sustained and therefore no liability for the penalty has been recorded. On September 30, 2013, the Internal Revenue Service issued a notice of deficiency to Exelon for the like-kind exchange position.Exelon filed a petition on December 13, 2013 to initiate litigation in the United States Tax Court. Exelon was not required to remit any part ofthe asserted tax or penalty in order to litigate the issue. The litigation could take three to five years including appeals, if necessary. Decisionsin the Tax Court are not controlled by the Federal Circuit’s decision in Consolidated Edison. 342Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) As of December 31, 2013, in the event of a fully successful IRS challenge to Exelon’s like-kind exchange position, the potential tax andafter-tax interest, exclusive of penalties, that could become currently payable may be as much as $840 million, of which approximately $305million would be attributable to ComEd after consideration of Exelon’s agreement to hold ComEd harmless, and the balance at Exelon.Litigation could take several years such that the estimated cash impacts would likely change by a material amount. Accounting for Generation Repairs (Exelon and Generation) On April 30, 2013, the IRS issued Revenue Procedure 2013-24 providing guidance for determining the appropriate tax treatment ofcosts incurred to repair electric generation assets. Generation expects to change its method of accounting for deducting repairs in accordancewith this guidance beginning with its 2014 tax year. Generation has estimated that adoption of the new method will result in a cash taxdetriment of approximately $100 - $120 million. Accounting for Electric Transmission and Distribution Property Repairs (Exelon, Generation, ComEd, PECO and BGE) On August 19, 2011, the IRS issued Revenue Procedure 2011-43 providing a safe harbor method of tax accounting for repair costsassociated with electric transmission and distribution property. ComEd and PECO adopted the safe harbor in the Revenue Procedure for the2011 and 2010 tax years, respectively. For the year ended December 31, 2011, the adoption of the safe harbor resulted in a $35 millionreduction to income tax expense at PECO, while Generation incurred additional income tax expense in the amount of $28 million due to adecrease in its domestic production activities deduction, which are reflected in the effective income tax rate reconciliation above in the plantbasis differences and domestic production activities deduction lines, respectively. For Exelon, the adoption had a minimal effect onconsolidated earnings. In addition, the adoption of the safe harbor resulted in a cash tax benefit at Exelon, ComEd and PECO in the amountof approximately $300 million, $250 million, $95 million respectively, partially offset by a cash tax detriment at Generation in the amount of$28 million related to a decreased domestic production activities deduction. BGE adopted the safe harbor for the short period 2012 pre-merger tax year. For the year ended December 31, 2012, the adoption of thesafe harbor resulted in a cash tax benefit at BGE in the amount of $27 million. See Note 3—Regulatory Matters for discussion of the regulatory treatment prescribed in the 2010 electric distribution rate casesettlement for PECO’s cash tax benefit resulting from the application of the method change to years prior to 2010. Accounting for Gas Distribution Property Repairs (Exelon, PECO and BGE). In September 2012, PECO filed an application with the IRS to change its method of accounting for gas distribution repairs for the 2011tax year. The change to the newly adopted method for the 2011 tax year and 2012 resulted in a tax benefit of $26 million at Exelon, of which$29 million in tax benefit is recorded at PECO, partially offset by an expense recorded at Generation to reflect a reduction in its domesticproduction activities deduction. BGE changed its method of accounting for gas distribution repairs for the 2008 tax year. The IRS is expectedto issue industry guidance in the near future. Exelon, PECO and BGE will then determine the financial statement impacts of the gasdistribution repair costs accounting method changes after guidance is issued. 343Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Accounting for Final Tangible Property Regulations (Exelon, Generation, ComEd, PECO, and BGE) On September 19, 2013, the Treasury Department and the IRS published final regulations regarding the tax treatment of costs incurredto acquire, produce, or improve tangible property. The Registrants have assessed the financial impact of this guidance and do not expect it tohave a material impact. Any changes in method of accounting required to conform to the final regulations will be made for the Registrant’s2014 taxable year. 2011 Illinois State Tax Rate Legislation (Exelon, Generation and ComEd) The Taxpayer Accountability and Budget Stabilization Act, (SB 2505), enacted into law in Illinois on January 13, 2011, increases thecorporate tax rate in Illinois from 7.3% to 9.5% for tax years 2011—2014, provides for a reduction in the rate from 9.5% to 7.75% for tax years2015—2024 and further reduces the rate from 7.75% to 7.3% for tax years 2025 and thereafter. Pursuant to the rate change, Exelon re-evaluated its deferred state income taxes during the first quarter of 2011. Illinois’ corporate income tax rate changes resulted in a charge tostate deferred taxes (net of Federal taxes) during the first quarter of 2011 of $7 million, $11 million and $4 million for Exelon, Generation andComEd, respectively. Exelon’s and ComEd’s charge is net of a regulatory asset of $15 million. In 2011, the income tax rate change increased Exelon’s Illinois income tax provision (net of Federal taxes) by approximately $7 million,of which $12 million and $5 million of additional tax relates to Exelon Corporate and Generation, respectively, and a $10 million benefit forComEd. The 2011 tax benefit at ComEd reflects the impact of a 2011 tax net operating loss generated primarily by the bonus depreciationdeduction allowed under the Tax Relief Act of 2010 and the electric transmission and distribution property repairs deduction discussed below. Long-Term State Tax Apportionment (Exelon and Generation) Exelon and Generation periodically review events that may significantly impact how income is apportioned among the states and,therefore, the calculation of Exelon’s and Generation’s deferred state income taxes. In 2011 as a result of the 2011 Illinois State Tax RateLegislation discussed above, Exelon and Generation re-evaluated their long-term state tax apportionment for Illinois and all other stateswhere they have state income tax obligations, resulting in recording a deferred state tax expense during the first quarter of 2011 of $22million and $11 million (net of Federal taxes) for Exelon and Generation, respectively. The long-term state tax apportionment also wasrevised in the fourth quarter of 2011 pursuant to long-term state tax apportionment policy, resulting in recording an additional deferred statetax expense of $1 million and a deferred state tax benefit of $8 million (net of Federal taxes) for Exelon and Generation, respectively. As a result of the merger with Constellation, Exelon and Generation re-evaluated their long-term state tax apportionment in the firstquarter of 2012. The total effect of revising the long-term state tax apportionment resulted in the recording of a deferred state tax asset of $72million (net of Federal taxes) for Exelon. Of this, a benefit in the amount of $116 million and $14 million (net of Federal taxes) was recordedfor Exelon and Generation, respectively, for the three months ended March 31, 2012. Further, Exelon and Generation recorded deferred statetax liabilities of $44 million and $14 million (net of Federal taxes), respectively, as part of purchase accounting during the three monthsended March 31, 2012. The long-term state tax apportionment also was updated in the fourth quarter of 2012, resulting in the recording of adeferred state tax benefit of $3 million (net of Federal taxes) for Exelon, and a deferred state tax expense of $7 million (net of Federal taxes)for Generation. There was no change to the long-term state tax apportionment for BGE, ComEd and PECO. 344Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The long-term state tax apportionment was revised in the fourth quarter of 2013 pursuant to its long-term state tax apportionment policy,resulting in the recording of amounts that are immaterial for Exelon and Generation, respectively. Allocation of Tax Benefits (Exelon, Generation, ComEd, PECO and BGE) Generation, ComEd, PECO and BGE are all party to an agreement with Exelon and other subsidiaries of Exelon that provides for theallocation of consolidated tax liabilities and benefits (Tax Sharing Agreement). The Tax Sharing Agreement provides that each party isallocated an amount of tax similar to that which would be owed had the party been separately subject to tax. In addition, any net benefitattributable to Exelon is reallocated to the other Registrants. That allocation is treated as a contribution to the capital of the party receiving thebenefit. During 2013, Generation and PECO recorded an allocation of Federal tax benefits from Exelon under the Tax Sharing Agreement of$26 million and $27 million, respectively. During 2013, ComEd and BGE did not record an allocation of Federal tax benefits from Exelonunder the Tax Sharing Agreement as a result of ComEd’s and BGE’s 2013 tax net operating loss generated primarily by the bonusdepreciation deduction allowed under the Tax Relief Act of 2010. During 2012, Generation and PECO recorded an allocation of Federal taxbenefits from Exelon under the Tax Sharing Agreement of $48 million and $9 million, respectively. During 2012, ComEd and BGE did notrecord an allocation of Federal tax benefits from Exelon under the Tax Sharing Agreement as a result of ComEd’s and BGE’s 2012 tax netoperating loss generated primarily by the bonus depreciation deduction allowed under the Tax Relief Act of 2010. ComEd received a non-cash contribution to equity from Exelon in 2012 of $11, related to tax benefits associated with capital projectsconstructed by ComEd on behalf of Exelon and Generation. 15. Asset Retirement Obligations (Exelon, Generation, ComEd, PECO and BGE) Nuclear Decommissioning Asset Retirement Obligations Generation has a legal obligation to decommission its nuclear power plants following the expiration of their operating licenses. Toestimate its decommissioning obligation related to its nuclear generating stations for financial accounting and reporting purposes, Generationuses a probability-weighted, discounted cash flow model which, on a unit-by-unit basis, considers multiple outcome scenarios that includesignificant estimates and assumptions, and are based on decommissioning cost studies, cost escalation rates, probabilistic cash flow modelsand discount rates. Generation generally updates its ARO annually during the third quarter, unless circumstances warrant more frequentupdates, based on its review of updated cost studies and its annual evaluation of cost escalation factors and probabilities assigned to variousscenarios. 345Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The following table provides a rollforward of the nuclear decommissioning ARO reflected on Exelon’s and Generation’s ConsolidatedBalance Sheets, from January 1, 2012 to December 31, 2013: Exelon andGeneration Nuclear decommissioning ARO at January 1, 2012 $3,680 Accretion expense 231 Net increase due to changes in, and timing of, estimated future cash flows 833 Costs incurred to decommission retired plants (3) Nuclear decommissioning ARO at December 31, 2012 4,741 Accretion expense 259 Net decrease due to changes in, and timing of, estimated future cash flows (140) Costs incurred to decommission retired plants (5) Nuclear decommissioning ARO at December 31, 2013 $4,855 (a)Includes $9 million and $10 million as the current portion of the ARO at December 31, 2013 and 2012, respectively, which is included in Other current liabilities onExelon’s and Generation’s Consolidated Balance Sheets. During 2013, Generation’s ARO increased by approximately $114 million. The increase is largely driven by an increase in theestimated costs to decommission the Limerick and Three Mile Island nuclear units resulting from the completion of updateddecommissioning costs studies received during 2013 and an increase for accretion of the obligation. These increases in the ARO were offsetby decreases to the ARO due to changes in long-term escalation rates, primarily for labor and energy costs, as well as changes in the timingof the future nominal cash flows coupled with the fact that cash flows affected by this change in timing are re-measured and discounted atcurrent credit adjusted risk free rates (CARFRs), which have increased from the prior year. The decrease in the ARO due to the changes in,and timing of, estimated cash flows were entirely offset by decreases in Property, plant and equipment within Exelon’s and Generation’sConsolidated Balance Sheets. During 2012, Generation’s ARO increased by $1,061 million. The increase in the ARO was largely driven by four factors: i) changes inthe timing of the future nominal cash flows resulting from an assumed five year deferral to 2025 of the acceptance date of spent nuclear fuelby the DOE coupled with the fact that; ii) cash flows affected by this change in timing are re-measured and discounted at current CARFRs,which had dramatically decreased given the lower interest rate environment; iii) an increase in the estimated costs to decommission theQuad Cities, Dresden and Clinton nuclear units resulting from the completion of updated decommissioning costs studies received during2012; and iv) accretion of the obligation. The increase in the ARO due to the changes in, and timing of, estimated cash flows resulted in $10million of expense, which is included in Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income. Nuclear Decommissioning Trust Fund Investments NDT funds have been established for each generating 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 the former ComEd, former PECO and former AmerGen units have been funded with amountscollected from ComEd customers, PECO customers and the previous owners of the former AmerGen plants, respectively. Based on an ICCorder, ComEd ceased collecting amounts from its customers to pay for decommissioning costs. PECO is authorized to collect funds, in 346(a)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) revenues, for decommissioning the former PECO nuclear plants through regulated rates, and these collections are scheduled through theoperating lives of the plants. The amounts collected from PECO customers are remitted to Generation and deposited into the NDT funds forthe unit for which funds are collected. Every five years, PECO files a rate adjustment with the PAPUC that reflects PECO’s calculations ofthe estimated amount needed to decommission each of the former PECO units based on updated fund balances and estimateddecommissioning costs. The rate adjustment is used to determine the amount collectible from PECO customers. The most recent rateadjustment occurred on January 1, 2013, and the effective rates currently yield annual collections of approximately $24 million. The nextfive-year adjustment is expected to be reflected in rates charged to PECO customers effective January 1, 2018. With respect to the formerAmerGen units, Generation does not collect any amounts, nor is there any mechanism by which Generation can seek to collect additionalamounts, from customers. Apart from the contributions made to the NDT funds from amounts collected from ComEd and PECO customers,Generation has not made contributions to the NDT funds. Any shortfall of funds necessary for decommissioning, determined for each generating station unit, is ultimately required to be fundedby Generation, with the exception of a shortfall for the current decommissioning activities at Zion Station, where certain decommissioningactivities have been transferred to a third-party (see Zion Station Decommissioning below). Generation has recourse to collect additionalamounts 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 associatedwith the first $50 million of any shortfall of trust funds, on an aggregate basis for all former PECO units, compared to decommissioningobligations, as well as 5% of any additional shortfalls. The initial $50 million and up to 5% of any additional shortfalls would be borne byGeneration. No recourse exists to collect additional amounts from ComEd customers for the former ComEd units or from the previousowners of the former AmerGen units. With respect to the former ComEd and PECO units, any funds remaining in the NDTs after alldecommissioning has been completed are required to be refunded to ComEd’s or PECO’s customers, subject to certain limitations thatallow sharing of excess funds with Generation related to the former PECO units. With respect to the former AmerGen units, Generationretains any funds remaining in the funds after decommissioning. During 2012, the NDT fixed income portfolio completed its transition from solely core fixed income investments to a blend of TreasuryInflation Protected Securities (TIPS), investment-grade corporate credit and middle market lending. There was no change in the equityinvestment strategy. At December 31, 2013, approximately 48% of the funds were invested in equity securities and 52% were invested infixed income securities. At December 31, 2012, approximately 47% of the funds were invested in equity securities and 53% were invested infixed income securities. At December 31, 2013, and 2012, Exelon and Generation had NDT fund investments totaling $8,071 million and $7,248 million,respectively. The following table provides unrealized gains (losses) on NDT funds for 2013, 2012 and 2011: Exelon and Generation For the Years Ended December 31, 2013 2012 2011 Net unrealized gains (losses) on decommissioning trustfunds—Regulatory Agreement Units $406 $386 $(74) Net unrealized gains (losses) on decommissioning trustfunds—Non-Regulatory Agreement Units 146 105 (4) 347(a)(b)(c)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Interest and dividends earned on the NDT fundinvestments for the Regulatory Agreement Units are eliminated within Other, net in Exelon’s and Generation’s Consolidated Statement ofOperations and Comprehensive Income. Accounting Implications of the Regulatory Agreements with ComEd and PECO. Based on the regulatory agreement with the ICCthat dictates Generation’s obligations related to the shortfall or excess of NDT funds necessary for decommissioning the former ComEd unitson a unit-by-unit basis, as long as funds held in the NDT funds are expected to exceed the total estimated decommissioning obligation,decommissioning-related activities, including realized and unrealized gains and losses on the NDT funds and accretion of thedecommissioning obligation, are generally offset within Exelon’s and Generation’s Consolidated Statements of Operations andComprehensive Income. The offset of decommissioning-related activities within the Consolidated Statement of Operations andComprehensive Income results in an equal adjustment to the noncurrent payables to affiliates at Generation and an adjustment to theregulatory liabilities at Exelon. Likewise, ComEd has recorded an equal noncurrent affiliate receivable from Generation and correspondingregulatory liability. Should the expected value of the NDT fund for any former ComEd unit fall below the amount of the expecteddecommissioning obligation for that unit, the accounting to offset decommissioning-related activities in the Consolidated Statement ofOperations and Comprehensive Income for that unit would be discontinued, the decommissioning-related activities would be recognized inthe Consolidated Statements of Operations and Comprehensive Income and the adverse impact to Exelon’s and Generation’s results ofoperations and financial position could be material. As of December 31, 2013, the NDT funds of each of the former ComEd units areexpected to exceed the related decommissioning obligation for each of the units. For the purposes of making this determination, thedecommissioning obligation referred to is different, as described below, from the calculation used in the NRC minimum funding obligationfilings based on NRC guidelines. Based on the regulatory agreement supported by the PAPUC that dictates Generation’s rights and obligations related to the shortfall orexcess of trust funds necessary for decommissioning the seven former PECO nuclear units, regardless of whether the funds held in theNDT funds are expected to exceed or fall short of the total estimated decommissioning obligation, decommissioning-related activities aregenerally offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income. The offset ofdecommissioning-related activities within the Consolidated Statement of Operations and Comprehensive Income results in an equaladjustment to the noncurrent payables to affiliates at Generation and an adjustment to the regulatory liabilities at Exelon. Likewise, PECOhas recorded an equal noncurrent affiliate receivable from Generation and a corresponding regulatory liability. Any changes to the PECOregulatory agreements could impact Exelon’s and Generation’s ability to offset decommissioning-related activities within the ConsolidatedStatement of Operations and Comprehensive Income, and the impact to Exelon’s and Generation’s results of operations and financialposition could be material. 348Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The decommissioning-related activities related to the Clinton, Oyster Creek and Three Mile Island nuclear plants (the former AmerGenunits) and the portions of the Peach Bottom nuclear plants that are not subject to regulatory agreements with respect to the NDT funds arereflected in Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income, as there are no regulatoryagreements associated with these units.

Zion Station Decommissioning On September 1, 2010, Generation completed an Asset Sale Agreement (ASA) with EnergySolutions Inc. and its wholly ownedsubsidiaries, EnergySolutions, LLC (EnergySolutions) and ZionSolutions under which ZionSolutions has assumed responsibility fordecommissioning Zion Station, which is located in Zion, Illinois and ceased operation in 1998. Specifically, Generation transferred toZionSolutions substantially all of the assets (other than land) associated with Zion Station, including assets held in related NDT funds. Inconsideration for Generation’s transfer of those assets, ZionSolutions assumed decommissioning and other liabilities, excluding theobligation to dispose of SNF, associated with Zion Station. Pursuant to the ASA, ZionSolutions will periodically request reimbursement fromthe Zion Station-related NDT funds for costs incurred related to the decommissioning efforts at Zion Station. During 2013, EnergySolutionsentered a definitive acquisition agreement and was acquired by another Company. Generation reviewed the acquisition as it relates to theASA to decommission Zion Station. Based on that review, Generation determined that the acquisition will not adversely impactdecommissioning activities under the ASA. On July 14, 2011, three people filed a purported class action lawsuit in the United States District Court for the Northern District ofIllinois naming ZionSolutions and Bank of New York Mellon as defendants and seeking, among other things, an accounting for use of NDTfunds, an injunction against the use of NDT funds, the appointment of a trustee for the NDT funds, and the return of NDT funds tocustomers of ComEd to the extent legally entitled thereto. On July 20, 2012, ZionSolutions and Bank of New York Mellon filed a motion todismiss the amended complaint for failing to state a claim. On July 29, 2013, United States District Court for the Northern District of Illinoisdismissed the amended complaint. On August 26, 2013, the plaintiffs filed a notice of appeal with the United States Court of Appeals for theSeventh Circuit. On January 31, 2014, the United States Court of Appeals for the Seventh Circuit dismissed the appeal. ZionSolutions is subject to certain restrictions on its ability to request reimbursements from the Zion Station NDT funds as definedwithin the ASA. Therefore, the transfer of the Zion Station assets did not qualify for asset sale accounting treatment and, as a result, therelated NDT funds were reclassified to pledged assets for Zion Station decommissioning within Generation’s and Exelon’s ConsolidatedBalance Sheets and will continue to be measured in the same manner as prior to the completion of the transaction. Additionally, thetransferred ARO for decommissioning was replaced with a payable to ZionSolutions in Generation’s and Exelon’s Consolidated BalanceSheets. Changes in the value of the Zion Station NDT assets, net of applicable taxes, will be recorded as a change in the payable toZionSolutions. At no point will the payable to ZionSolutions exceed the project budget of the costs remaining to decommission Zion Station.Generation has retained its obligation to the SNF following ZionSolutions completion of its contractual obligations, to transfer the SNF at ZionStation to the DOE for ultimate disposal, and to complete all remaining decommissioning activities associated with the SNF 349Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Generation has a liability of approximately $82 million, which is included within the nuclear decommissioning ARO atDecember 31, 2013. Generation also has retained NDT assets to fund its obligation to maintain and transfer the SNF at Zion Station and tocomplete all remaining decommissioning activities for the SNF storage facility. Any shortage of funds necessary to maintain the SNF anddecommission the SNF storage facility is ultimately required to be funded by Generation. Any Zion Station NDT funds remaining after thecompletion of all decommissioning activities will be returned to ComEd customers in accordance with the applicable orders. The followingtable provides the pledged assets and payable to ZionSolutions, and withdrawals by ZionSolutions at December 31, 2013 and 2012: Exelon and Generation 2013 2012 Carrying value of Zion Station pledged assets $458 $614 Payable to Zion Solutions 414 564 Current portion of payable to Zion Solutions 109 132 Withdrawals by Zion Solutions to pay decommissioning costs 498 335 (a)Excludes a liability recorded within Exelon’s and Generation’s Consolidated Balance Sheets related to the tax obligation on the unrealized activity associated with theZion Station NDT Funds.

ZionSolutions leased the land associated with Zion Station from Generation pursuant to a Lease Agreement. Under the LeaseAgreement, ZionSolutions has committed to complete the required decommissioning work according to an established schedule and willconstruct a dry cask storage facility on the land for the SNF currently held in SNF pools at Zion Station. Rent payable under the LeaseAgreement is $1.00 per year, although the Lease Agreement requires ZionSolutions to pay property taxes associated with Zion Station andpenalty rents may accrue if there are unexcused delays in the progress of decommissioning work at Zion Station or the construction of thedry cask SNF storage facility. To reduce the risk of default by EnergySolutions or ZionSolutions, EnergySolutions provided a $200 millionletter of credit to be used to fund decommissioning costs in the event the NDT assets are insufficient. EnergySolutions has also provided aperformance guarantee and entered into other agreements that will provide rights and remedies for Generation and the NRC in the case ofother specified events of default, including a special purpose easement for disposal capacity at the EnergySolutions site in Clive, Utah, for allLLRW volume of Zion Station. NRC Minimum Funding Requirements. NRC regulations require that licensees of nuclear generating facilities demonstratereasonable assurance that funds will be available in specified minimum amounts to decommission the facility at the end of its life. Theestimated decommissioning obligations as calculated using the NRC methodology differ from the ARO recorded on Generation’s andExelon’s Consolidated Balance Sheets primarily due to differences in the type of costs included in the estimates, the basis for estimatingsuch costs, and assumptions regarding the decommissioning alternatives to be used, potential license renewals, decommissioning costescalation, and the growth rate in the NDT funds. Under NRC regulations, if the minimum funding requirements calculated under the NRCmethodology are less than the future value of the NDT funds, also calculated under the NRC methodology, then the NRC requires eitherfurther funding or other financial guarantees. Key assumptions used in the minimum funding calculation using the NRC methodology at December 31, 2013 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 350(a)(b)(c)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In contrast, the key criteria and assumptions used by Generation to determine the ARO and to forecast the target growth in the NDTfunds at December 31, 2013 include: (1) the use of site specific cost estimates that are updated at least once every five years; (2) the inclusionin the ARO estimate of all legally unavoidable costs required to decommission the unit (e.g., radiological decommissioning and full siterestoration for certain units, on-site spent fuel maintenance and storage subsequent to ceasing operations and until DOE acceptance, anddisposal of certain low-level radioactive waste); (3) the consideration of multiple scenarios where decommissioning activities are completedunder three possible scenarios ranging from 10 to 70 years after the cessation of plant operations; (4) the assumption plants cease operatingat the end of an extended license life (assuming 20-year license renewal extensions, except Oyster Creek with an assumed end-of-operations date of 2019); (5) the measurement of the obligation at the present value of the future estimated costs and an annual averageaccretion 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 5.9% to 6.7% (as compared to a historical 5-year annual average pre-taxreturn of approximately 11.7%). Generation is required to provide to the NRC a biennial report by unit (annually for units that have been retired or are within five yearsof the current approved license life), based on values as of December 31, addressing Generation’s ability to meet the NRC minimumfunding levels. Depending on the value of the trust funds, Generation may be required to take steps, such as providing financial guaranteesthrough letters of credit or parent company guarantees or make additional contributions to the trusts, which could be significant, to ensurethat the trusts are adequately funded and that NRC minimum funding requirements are met. As a result, Exelon’s and Generation’s cashflows and financial position may be significantly adversely affected. On April 1, 2013, Generation submitted its NRC-required biennial decommissioning funding status report as of December 31,2012. As of December 31, 2012, Generation provided adequate funding assurance for all of its units, including Limerick Unit 1, whereGeneration has in place a $115 million parent guarantee to cover the NRC minimum funding assurance requirements. On October 2, 2013,the NRC issued summary findings from the NRC Staff’s review of the 2013 decommissioning funding status reports for all 104 operatingreactors, including the Generation operating units. Based on that review, the NRC Staff determined that Generation provideddecommissioning funding assurance under the NRC regulations for all of its operating units, including Limerick Unit 1. On January 31, 2013, Generation received a letter from the NRC indicating that the NRC has identified potential “apparent violations”of its regulations because of alleged inaccuracies in the Decommissioning Funding Status reports for 2005, 2006, 2007, and 2009. The NRCasserted that Generation’s status reports deliberately reflected cost estimates for decommissioning its nuclear plants that were less thanwhat the NRC says are the minimum amounts required by NRC regulations. Generation met with the NRC on April 30, 2013 for a pre-decisional enforcement conference to provide additional information to explain why Generation believes that it complied with the regulatoryrequirements and did not deliberately or otherwise provide incomplete or inaccurate information in its decommissioning funding statusreports. While Generation does not believe that any sanction is appropriate, the ultimate outcome of this proceeding including the amount ofa potential fine or sanction, if any, is uncertain.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Generation’s current funding status, and as reflected in Generation’s April 1, 2013 decommissioning funding status report referenced above,Generation continues to provide adequate funding assurance for each of its units. In the normal course of NRC review, Generation hasreceived a series of data requests that are unrelated to the potential apparent violations and the pre-decisional enforcement conference.Generation continues to cooperate with the NRC and provide the requested information. Generation does not have a definite date on which itwill receive a response from the NRC. In addition, on June 24, 2013, Exelon received a subpoena from the SEC requesting that Exelon provide the SEC with certaindocuments generally relating to Exelon and Generation’s reporting and funding of the future decommissioning of Exelon’s nuclear powerplants. Exelon and Generation are cooperating with the SEC and providing the requested documents. As the future values of trust funds change due to market conditions, the NRC minimum funding status of Generation’s units willchange. In addition, if changes occur to the regulatory agreement with the PAPUC that currently allows amounts to be collected from PECOcustomers for decommissioning the former PECO nuclear plants, the NRC minimum funding status of those plants could change atsubsequent NRC filing dates. Non-Nuclear Asset Retirement Obligations (Exelon, Generation, ComEd, PECO and BGE) Generation has AROs for plant closure costs associated with its fossil and renewable generating facilities, including asbestosabatement, removal of certain storage tanks, restoring leased land to the condition it was in prior to construction of renewable generatingstations and other decommissioning-related activities.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Exelon’s traditional and cash balance pension plans are intended to be tax-qualified defined benefit plans. Substantially all non-unionemployees 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. Exelon has elected that the trustsunderlying these plans be treated under the IRC as qualified trusts. If certain conditions are met, Exelon can deduct payments made to thequalified trusts, subject to certain IRC limitations. Benefit Obligations, Plan Assets and Funded Status Exelon recognizes the overfunded or underfunded status of defined benefit pension and other postretirement benefit plans as an assetor liability on its balance sheet, with offsetting entries to Accumulated Other Comprehensive Income (AOCI) and regulatory assets(liabilities), in accordance with the applicable authoritative guidance. The measurement date for the plans is December 31. During the first quarter of 2013, Exelon received an updated valuation of its legacy pension and other postretirement benefit obligationsto reflect actual census data as of January 1, 2013. This valuation resulted in an increase to the pension obligation of $8 million and adecrease to the other postretirement benefit obligation of $39 million. Additionally, accumulated other comprehensive loss decreased byapproximately $75 million (after tax) and regulatory assets increased by approximately $93 million. During the second quarter of 2013,Exelon received the updated valuation for the legacy Constellation pension and other postretirement obligations to reflect actual census dataas of January 1, 2013. This valuation resulted in an increase to the pension obligation of $23 million and a decrease to the otherpostretirement benefit obligation of $12 million. Additionally, accumulated other comprehensive loss increased by approximately $2 million(after tax) and regulatory assets increased by approximately $14 million. The following table provides a rollforward of the changes in the benefit obligations and plan assets for the most recent two years for allplans combined: Pension Benefits OtherPostretirement Benefits 2013 2012 2013 2012 Change in benefit obligation: Net benefit obligation at beginning of year $16,800 $13,538 $4,820 $4,062 Service cost 317 280 162 156 Interest cost 650 698 194 205 Plan participants’ contributions — — 34 34 Actuarial loss (gain) (1,363) 1,520 (551) 313 Plan amendments 1 — 15 (103) Acquisitions/divestitures — 1,880 — 362 Curtailments — (10) — (8) Settlements (69) (169) — — Contractual termination benefits — 15 — 6 Gross benefits paid (877) (952) (223) (219) Federal subsidy on benefits paid — — — 12 Net benefit obligation at end of year $15,459 $16,800 $4,451 $4,820 354(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Components of Net Periodic Benefit Costs The following table presents the components of Exelon’s net periodic benefit costs for the years ended December 31, 2013, 2012 and2011. The table reflects an increase in 2012 and a reduction in 2011 of net periodic postretirement benefit costs of approximately $(17) millionand $28 million, respectively, related to a Federal subsidy provided under the Medicare Prescription Drug, Improvement and ModernizationAct of 2003 (Medicare Modernization Act), discussed further below. The 2013 pension benefit cost for all plans is calculated using an expected long-term rate of return on plan assets of 7.50% and adiscount rate of 3.92%. Certain plans were remeasured during the year using a discount rate of 4.21%. The 2013 other postretirementbenefit cost is calculated using an expected long-term rate of return on plan assets of 6.45% for funded plans and a discount rate of 4.00% forall plans. Certain plans were remeasured during the year using a discount rate of 4.66%. Certain other postretirement benefit plans are notfunded. A portion of the net periodic benefit cost is capitalized within the Consolidated Balance Sheets.

Through Exelon’s postretirement benefit plans, the Registrants provide retirees with prescription drug coverage. The MedicareModernization Act, enacted on December 8, 2003, introduced a prescription drug benefit under Medicare as well as a Federal subsidy tosponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to the Medicare prescription drugbenefit. Management believes the prescription drug benefit provided under Exelon’s postretirement benefit plans meets the requirements forthe subsidy. In December 2011, the Company decided that beginning in 2013, it will no longer elect to take the direct Part D subsidy.Beginning in 2013, eligible employees are offered an Employee Group Waiver Plan, a Medicare Part D Plan, with a supplemental “wrap”that closely matches the current prescription drug plan design.

Assumptions The measurement of the plan obligations and costs of providing benefits under Exelon’s defined benefit and other postretirement plansinvolves various factors, including the development of valuation assumptions and accounting policy elections. When developing the requiredassumptions, Exelon considers historical information as well as future expectations. The measurement of benefit obligations and costs isimpacted by several assumptions including the discount rate applied to benefit obligations, the long-term expected rate of return on planassets, Exelon’s expected level of contributions to the plans, the long-term expected investment rate credited to employees participating incash balance plans and the anticipated rate of increase of health care costs. Additionally, assumptions related to plan participants include theincidence of mortality, the expected remaining service period, the level of compensation and rate of compensation increases, employee ageand length of service, among other factors. 358 (a) (a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Expected Rate of Return. In selecting the expected rate of return on plan assets, Exelon considers historical economic indicators(including inflation and GDP growth) that impact asset returns, as well as expectations regarding future long-term capital marketperformance, weighted by Exelon’s target asset class allocations. The following assumptions were used to determine the benefit obligations for all of the plans at December 31, 2013, 2012 and 2011.Assumptions used to determine year-end benefit obligations are the assumptions used to estimate the subsequent year’s net periodic benefitcosts.

Certain of the benefit plans were remeasured during the year using discount rates of 4.21% and 4.66% for pension and other postretirementbenefits, respectively. Costs for the year ended December 31, 2013 reflect the impact of these remeasurements.(b)The discount rates above represent the initial discounts rates used to establish Exelon’s pension and other postretirement benefits costs for 2012. Certain of the benefitplans were remeasured during the year due to the Constellation merger, plan settlement and curtailment events, and plan changes using discount rates of 3.71%and 3.72% for pension and other postretirement benefits, respectively. Costs for the year ended December 31, 2012 reflect the impact of these remeasurements.(c)Not applicable to pension and other postretirement benefit plans that do not have plan assets.(d)3.25% for 2013-2017 and 3.75% thereafter. Assumed health care cost trend rates have a significant effect on the costs reported for the other postretirement benefit plans. A onepercentage point change in assumed health care cost trend rates would have the following effects: Effect of a one percentage point increase in assumed health care cost trend: on 2013 total service and interest cost components $90 on postretirement benefit obligation at December 31, 2013 858 Effect of a one percentage point decrease in assumed health care cost trend: on 2013 total service and interest cost components (62) on postretirement benefit obligation at December 31, 2013 (607) Health Care Reform Legislation In March 2010, the Health Care Reform Acts were signed into law, which contain a number of provisions that impact retiree health careplans provided by employers. One such provision reduces the deductibility, for Federal income tax purposes, of retiree health care costs to theextent an employer’s postretirement health care plan receives Federal subsidies that provide retiree prescription drug benefits at leastequivalent to those offered by Medicare. Although this change did not take effect immediately, the Registrants were required to recognize thefull accounting impact in their financial statements in the period in which the legislation was enacted. As a result, in the first quarter of 2010,Exelon recorded total after-tax charges of approximately $65 million to income tax expense to reverse deferred tax assets previouslyestablished. Generation, ComEd, PECO and BGE recorded charges of $24 million, $11 million, $9 million and $3 million, respectively.Additionally, as a result of this deductibility change for employers and other Health Care Reform provisions that impact the federalprescription drug subsidy options provided to employers, Exelon has made a change in the manner in which it will receive prescription drugsubsidies beginning in 2013. Additionally, the Health Care Reform Acts also include a provision that imposes an excise tax on certain high-cost plans beginning in2018, whereby premiums paid over a prescribed threshold will be taxed at a 40% rate. Although the excise tax does not go into effect until2018, accounting guidance requires Exelon to incorporate the estimated impact of the excise tax in its annual actuarial valuation. Theapplication of the legislation is still unclear and Exelon continues to monitor the Department of Labor and IRS for additional guidance. Certainkey assumptions are required to estimate the impact of the excise tax on Exelon’s other postretirement benefit obligation, including projectedinflation rates (based on the CPI) and whether pre- and post-65 retiree populations can be aggregated in determining the premium values ofhealth care benefits. Exelon reflected its best estimate of the expected impact in its annual actuarial valuation. 360Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Effective January 1, 2013, Exelon is no longer receiving this subsidy.(b)BGE’s pension benefit contributions for 2012 and 2011 exclude $0 million and $54 million, respectively, of pension contributions made by BGE prior to the closing ofExelon’s merger with Constellation on March 12, 2012. BGE’s other postretirement benefit payments for 2012 and 2011 exclude $4 million and $13 million,respectively, of other postretirement benefit payments made by BGE prior to the closing of Exelon’s merger with Constellation on March 12, 2012. These pre-mergercontributions are not included in Exelon’s financial statements but are reflected in BGE’s financial statements.(c)The increase in 2011 pension contributions was related to Exelon’s $2.1 billion contribution to its pension plans as a result of accelerated cash benefits associated withthe Tax Relief Act of 2010. Exelon plans to contribute $264 million to its qualified pension plans in 2014, of which Generation, ComEd, PECO and BGE willcontribute $118 million, $119 million, $11 million and $0 million, respectively. Unlike the qualified pension plans, Exelon’s non-qualifiedpension plans are not funded. Exelon plans to make non-qualified pension plan benefit payments of $12 million in 2014, of whichGeneration, ComEd, PECO and BGE will make payments of $5 million, $1 million, $0 million and $1 million, respectively. Managementconsiders various factors when making pension funding decisions, including actuarially determined minimum contribution requirementsunder 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 benefitrestrictions (such as an inability to pay lump sums or to accrue benefits prospectively), and at-risk status (which triggers higher minimumcontribution requirements and participant notification). Additionally, for Exelon’s largest qualified pension plan, the projected contributionsreflect a funding strategy of contributing the greater of $250 million, which approximates service cost, or the minimum amounts underERISA to avoid benefit restrictions and at-risk status. This level funding strategy helps minimize volatility of future period required pensioncontributions. On July 6, 2012, President Obama signed into law the Moving Ahead for Progress in the Twenty-first Century Act, whichcontains a pension funding provision that results in lower minimum pension contributions in the near term while increasing the premiumspension plans pay to the Pension Benefit Guaranty Corporation. Certain provisions of the law were applied in 2012 while others wereapplied in 2013. The estimated impacts of the law are reflected in the projected pension contributions. Unlike the qualified pension plans, other postretirement plans are not subject to statutory minimum contribution requirements.Exelon’s management has historically considered several factors in determining the level of contributions to its other postretirement benefitplans, including levels of benefit claims paid and regulatory implications (amounts deemed prudent to meet regulatory expectations and 361(c)(a)(a)(a)(b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In 2014, Exelon anticipates funding its other postretirement benefit plans based on the fundingconsiderations discussed above, with the exception of those plans which remain unfunded. Exelon expects to make other postretirementbenefit plan contributions, including benefit payments related to unfunded plans, of approximately $430 million in 2014, of whichGeneration, ComEd, PECO, and BGE expect to contribute $168 million, $197 million, $19 million, and $17 million, respectively. Estimated Future Benefit Payments Estimated future benefit payments to participants in all of the pension plans and postretirement benefit plans at December 31, 2013were: PensionBenefits OtherPostretirementBenefits 2014 $929 $204 2015 851 210 2016 873 219 2017 902 228 2018 1,015 238 2019 through 2023 5,257 1,383 Total estimated future benefit payments through 2023 $9,827 $2,482 Allocation to Exelon Subsidiaries Generation, ComEd, PECO, and BGE account for their participation in Exelon’s pension and other postretirement benefit plans byapplying multiemployer accounting. Employee-related assets and liabilities, including both pension and postretirement liabilities, for thelegacy Exelon plans were allocated by Exelon to its subsidiaries based on the number of active employees as of January 1, 2001 as part ofExelon’s corporate restructuring. Exelon allocates the components of pension and other postretirement costs to the subsidiaries in the legacyExelon plans based upon several factors, including the measures of active employee participation in each participating unit. The obligation forGeneration, ComEd and PECO reflects the initial allocation and the cumulative costs incurred and contributions made since January 1,2001. Pension and postretirement benefit contributions are allocated to legacy Exelon subsidiaries in proportion to active service costsrecognized and total costs recognized, respectively. For legacy CEG plans, components of pension and other postretirement benefit costs andcontributions are allocated to the subsidiaries based on employee participation (both active and retired). The amounts below were included in capital expenditures and operating and maintenance expense for the years ended December 31,2013, 2012 and 2011, respectively, for Generation’s, ComEd’s, PECO’s, BSC’s and BGE’s allocated portion of the pension andpostretirement benefit plan costs. These amounts include the recognized contractual termination benefit charges, curtailment gains, andsettlement charges: For the Year Ended December 31, Generation ComEd PECO BSC BGE Exelon 2013 $347 $309 $43 $71 $55 $825 2012 341 282 50 99 60 820 2011 249 213 32 48 51 542 362(a)(b)(c)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Plan Assets Investment Strategy. On a regular basis, Exelon evaluates its investment strategy to ensure that plan assets will be sufficient to payplan benefits when due. As part of this ongoing evaluation, Exelon may make changes to its targeted asset allocation and investmentstrategy. Exelon has developed and implemented a liability hedging investment strategy for its qualified pension plans that has reduced thevolatility of its pension assets relative to its pension liabilities. Exelon is likely to continue to gradually increase the liability hedging portfolioas the funded status of its plans improves. The overall objective is to achieve attractive risk-adjusted returns that will balance the liquidityrequirements of the plans’ liabilities while striving to minimize the risk of significant losses. Trust assets for Exelon’s other postretirementplans are managed in a diversified investment strategy that prioritizes maximizing liquidity and returns while minimizing asset volatility. Exelon used an EROA of 7.00% and 6.59% to estimate its 2014 pension and other postretirement benefit costs, respectively. Exelon’s pension and other postretirement benefit plan target asset allocations and December 31, 2013 and 2012 asset allocationswere as follows: Pension Plans Percentage of Plan Assetsat December 31, Asset Category Target Allocation 2013 2012 Equity securities 31% 35% 35% Fixed income securities 38% 37 40 Alternative investments 31% 28 25 Total 100% 100% Other Postretirement Benefit Plans Percentage of Plan Assetsat December 31, Asset Category Target Allocation 2013 2012 Equity securities 41% 45% 46% Fixed income securities 39% 37 40 Alternative investments 20% 18 14 Total 100% 100% 363(a)(a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Concentrations of Credit Risk. Exelon evaluated its pension and other postretirement benefit plans’ asset portfolios for the existence ofsignificant concentrations of credit risk as of December 31, 2013. 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, 2013, there were nosignificant concentrations (defined as greater than 10 percent of plan assets) of risk in Exelon’s pension and other postretirement benefit planassets.

As such, these hedge fund investments are reflected as transfers out of Level 3 to Level 2 of$627 million in 2013.(c)In connection with the acquisition of Constellation in March 2012, Exelon assumed Constellation’s pension plan assets resulting in transfers into Level 3 of $141million.(d)In 2012, Exelon refined its policy over the criteria that hedge fund investments must meet in order to be categorized within Level 2 and Level 3 of the fair valuehierarchy. Therefore, certain hedge fund investments that were categorized within Level 3 in prior periods have been re-categorized as Level 2 investments as ofDecember 31, 2012. The re-categorization of these hedge fund investments is reflected as transfers out of Level 3 of $1.1 billion.(e)In 2012, the liquidity terms of a certain real estate investment changed to allow redemption within a reasonable period of time from the redemption date which led toa transfer out of Level 3 to Level 2 of $5 million. Valuation Techniques Used to Determine Fair Value Cash equivalents. Investments with maturities of three months or less when purchased, including certain short—term fixed incomesecurities 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. Equity securities. With respect to individually held equity securities, including investments in U.S. and international securities, thetrustees obtain prices from pricing services, whose prices are obtained from direct feeds from market exchanges, which Exelon is able toindependently corroborate.

Equity securities are valued based on quoted prices in active markets and are categorized asLevel 1. Certain private placement equity securities are categorized as Level 3 because they are not publicly traded and are priced usingsignificant unobservable inputs. Equity commingled funds and mutual funds are maintained by investment companies that hold certain investments in accordance witha stated set of fund objectives, which are consistent with Exelon’s overall investment strategy. The values of some of these funds are publiclyquoted. For mutual funds which are publicly quoted, the funds are valued based on quoted prices in active markets and have beencategorized as Level 1. For equity commingled funds and mutual funds which are not publicly quoted, the fund administrators value thefunds using the net asset value per fund share, derived from the quoted prices in active markets of the underlying securities. These fundshave been categorized as Level 2. Fixed income. For fixed income securities, which consist primarily of corporate debt securities, foreign government securities,municipal bonds, asset and mortgage-backed securities, commingled funds, mutual funds and derivative instruments, the trustees obtainmultiple prices from pricing vendors whenever possible, which enables cross-provider validations in addition to checks for unusual dailymovements. A primary price source is identified based on asset type, class or issue for each security. The trustees monitor prices supplied bypricing services and may use a supplemental price source or change the primary price source of a given security if the portfolio managerschallenge an assigned price and the trustees determine that another price source is considered to be preferable. Exelon has obtained anunderstanding of how these prices are derived, including the nature and observability of the inputs used in deriving such prices. Additionally,Exelon selectively corroborates the fair values of securities by comparison to other market-based price sources. Investments in U.S. Treasurysecurities have been categorized as Level 1 because they trade in highly-liquid and transparent markets. Certain private placement fixedincome securities have been categorized as Level 3 because they are priced using certain significant unobservable inputs and are typicallyilliquid. The fair values of fixed income securities, excluding U.S. Treasury securities and privately placed fixed income securities, are basedon evaluated prices that reflect observable market information, such as actual trade information of similar securities, adjusted for observabledifferences and are categorized as Level 2. Derivative instruments consisting primarily of interest rate swaps to manage risk are recorded at fair value. Derivative instruments arevalued based on external price data of comparable securities and have been categorized as Level 2. Fixed income commingled funds and mutual funds, including short-term investment funds, are maintained by investment companiesand hold certain investments in accordance with a stated set of fund objectives, which are consistent with Exelon’s overall investmentstrategy. The values of some of these funds are publicly quoted. For mutual funds which are publicly quoted, the funds are valued based onquoted prices in active markets and have been categorized as Level 1. For fixed income commingled funds and mutual funds which are notpublicly quoted, the fund administrators value the funds using the net asset value per fund share, derived from the quoted prices in activemarkets of the underlying securities. These funds have been categorized as Level 2. Private equity. Private equity investments include those in limited partnerships that invest in operating companies that are not publiclytraded on a stock exchange such as leveraged buyouts, growth capital, venture capital, distressed investments and investments in naturalresources.

Since these valuation inputs are not highlyobservable, private equity investments have been categorized as Level 3. Hedge funds. Hedge fund investments include those seeking to maximize absolute returns using a broad range of strategies toenhance returns and provide additional diversification. The fair value of hedge funds is determined using NAV or ownership interest of theinvestments. Exelon has the ability to redeem these investments at NAV or its equivalent subject to certain restrictions which may include alock-up period or a gate. For Exelon’s investments that have terms that allow redemption within a reasonable period of time from themeasurement date, the hedge fund investments are categorized as Level 2. For investments that have restrictions that may limit Exelon’sability to redeem the investments at the measurement date or within a reasonable period of time, the hedge fund investments are categorizedas Level 3.

Since these funds are not publicly quoted, the fund administrators value thefunds using the net asset value per fund share, derived from the quoted prices in active markets of the underlying securities. These fundshave been categorized as Level 2. Other real estate funds are funds with a direct investment in a pool of real estate properties. These fundsare valued by investment managers on a periodic basis using pricing models that use independent appraisals from sources with professionalqualifications. Since these valuation inputs are not highly observable, these real estate funds have been categorized as Level 3. Defined Contribution Savings Plan (Exelon, Generation, ComEd, PECO and BGE) The Registrants participate in various 401(k) defined contribution savings plans that are sponsored by Exelon. The plans are qualifiedunder applicable sections of the IRC and allow employees to contribute a portion of their pre-tax income in accordance with specifiedguidelines. All Registrants match a percentage of the employee contributions up to certain limits. The following table presents matchingcontributions to the savings plan for the years ended December 31, 2013, 2012 and 2011: For the Year Ended December 31, Exelon Generation ComEd PECO BGE BSC 2013 $85 $40 $22 $8 $8 $7 2012 67 30 19 7 7 5 2011 78 40 22 9 7 7 (a)BGE’s matching contributions for the years ended December 31, 2012 and 2011 include $1 million and $7 million of costs, respectively, incurred prior to the closing ofExelon’s merger with Constellation on March 12, 2012. These costs are not included in Exelon’s matching contributions for the years ended December 31, 2012 and2011.(b)These amounts primarily represent amounts billed to Exelon’s subsidiaries through intercompany allocations. These costs are not included in the Generation,ComEd, PECO, or BGE amounts above. 17. Severance (Exelon, Generation, ComEd, PECO and BGE) The Registrants have an ongoing severance plan under which, in general, the longer an employee worked prior to termination thegreater the amount of severance benefits.

For severance benefits that are incremental to its ongoing severance plan(“one-time termination benefits”), the Registrants measure the obligation and record the expense at fair value at the communication date ifthere are no future service requirements, or, if future service is required to receive the termination benefit, ratably over the required serviceperiod. Merger-Related Severance Upon closing the merger with Constellation, Exelon recorded a severance accrual for the anticipated employee position reductions as aresult of the post-merger integration. The majority of these positions are corporate and Generation support positions. Since then, Exelon hasidentified specific employees to be severed pursuant to the merger-related staffing and selection process as well as employees that werepreviously identified for severance but have since accepted another position within Exelon and are no longer receiving a severance benefit.Exelon adjusts its accrual each quarter to reflect its best estimate of remaining severance costs. In addition, certain employees identifiedduring the staffing and selection process also receive pension and other postretirement benefits that are deemed contractual terminationbenefits, which the Registrants recorded during the second quarter of 2012. The amount of severance expense associated with the post-merger integration recognized for the year ended December 31, 2013 forExelon and Generation was $6 million and $6 million, respectively. For Generation, $5 million represents amounts billed by BSC throughintercompany allocations. There was no severance expense associated with post-merger integration recognized for the year endedDecember 31, 2013 for ComEd, PECO and BGE. Estimated costs to be incurred after December 31, 2013 are not material. For the year ended December 31, 2012, the Registrants recorded the following severance benefit costs associated with the identified jobreductions within operating and maintenance expense in their Consolidated Statements of Operations, except for those costs that werecapitalized as regulatory assets related to ComEd and BGE: Year Ended December 31, 2012Severance Benefits Exelon Generation ComEd PECO BGE Severance charges $124 $80 $14 $7 $17 Stock compensation 7 4 1 — 1 Other charges 7 4 1 — 1 Total severance benefits $138 $88 $16 $7 $19 (a)The amounts above include $46 million at Generation, $14 million at ComEd, $7 million at PECO, and $7 million at BGE, for amounts billed by BSC throughintercompany allocations for the year ended December 31, 2012.(b)Exelon, ComEd and BGE established regulatory assets of $35 million, $16 million and $19 million, respectively, for severance benefits costs for the year endedDecember 31, 2012.

In April 2004, Exelon’s Board of Directors approved a discretionary share repurchase program thatallowed Exelon to repurchase shares of its common stock on a periodic basis in the open market. The share repurchase program wasintended to mitigate, in part, the dilutive effect of shares issued under Exelon’s employee stock option plan and Exelon’s ESPP. Theaggregate value of the shares of common stock repurchased pursuant to the program cannot exceed the economic benefit received afterJanuary 1, 2004 due to stock option exercises and share purchases pursuant to Exelon’s ESPP. The economic benefit consists of the directcash proceeds from purchases of stock and the tax benefits associated with exercises of stock options. The 2004 share repurchase programhad no specified limit on the number of shares that could be repurchased and no specified termination date. In 2008, Exelon managementdecided to defer indefinitely any share repurchases. Any shares repurchased are held as treasury shares, at cost, unless cancelled orreissued at the discretion of Exelon’s management. Under the share repurchase programs, 35 million shares of common stock are held astreasury stock with a cost of $2.3 billion at December 31, 2013. During 2013, 2012 and 2011, Exelon had no common stock repurchases. 375 (a)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Stock-Based Compensation Plans Exelon grants stock-based awards through its LTIP, which primarily includes stock options, restricted stock units and performanceshare awards. At December 31, 2013, there were approximately 16 million shares authorized for issuance under the LTIP. For the yearsended December 31, 2013, 2012 and 2011, exercised and distributed stock-based awards were primarily issued from authorized butunissued common stock shares. The Compensation Committee of Exelon’s Board of Directors changed the mix of awards granted under the LTIP in 2013 byeliminating stock options in favor of the use of full value shares, consisting of performance shares and restricted stock. The performanceshare awards granted in 2013 will cliff vest at the end of a three-year performance period. The performance share awards granted in 2012 andearlier had a one-year performance period and vested ratably over three years. To address the reduction in annual award opportunity resultingfrom the transition to a three-year cliff vesting performance period, the Compensation Committee also approved a one-time grant ofperformance share transition awards in 2013, which will vest one-third after one year, with the remaining balance vesting over a two-yearperformance period.

In addition, the stock-based compensation expense at ComEd does not reflect the impact of the ComEd Key Manager Long-Term PerformanceProgram in 2013 for certain employees, which is not considered stock-based compensation expense under the applicable authoritative guidance. In 2012, theseemployees participated in the Exelon Restricted Stock Award Program.(d)The total stock-based compensation expense (pre-tax) for December 31, 2011 of $69 million does not include the $6 million expense for BGE as those costs wereincurred prior to the closing of Exelon’s merger with Constellation on March 12, 2012. There were no significant stock-based compensation costs capitalized during the years ended December 31, 2013, 2012 and 2011. Exelon receives a tax deduction based on the intrinsic value of the award on the exercise date for stock options and the distribution datefor performance share awards and restricted stock units. For each award, throughout the requisite service period, Exelon recognizes the taxbenefit related to compensation costs. The tax deductions in excess of the benefits recorded throughout the requisite service period arerecorded to common stock and are included in other financing activities within Exelon’s Consolidated Statements of Cash Flows. Thefollowing table presents information regarding Exelon’s tax benefits for the years ended December 31, 2013, 2012 and 2011: Year EndedDecember 31, 2013 2012 2011 Realized tax benefit when exercised/distributed: Stock options $— $3 $2 Restricted stock units 11 11 8 Performance share awards 11 7 7 Stock deferral plan 1 — 1 Excess tax benefits included in other financing activities of Exelon’s Consolidated Statements of Cash Flows: Stock options $— $2 $1 Stock Options Non-qualified stock options to purchase shares of Exelon’s common stock are granted under the LTIP. The exercise price of the stockoptions is equal to the fair market value of the underlying stock on the date of option grant. The vesting period of stock options is generallyfour years. All stock options expire ten years from the date of grant. There were no stock options granted in 2013. The Compensation Committee eliminated stock option grants by changing the mix oflong-term incentives for senior vice presidents (SVPs) and higher officers from 75% performance shares and 25% stock options to 67%performance shares and 33% restricted stock units. The value of stock options at the date of grant is expensed over the requisite service period using the straight-line method. The requisiteservice period for stock options is generally four years. However, certain stock options become fully vested upon the employee reachingretirement-eligibility. The value of the stock options granted to retirement-eligible employees is either recognized immediately upon the date ofgrant or through the date at which the employee reaches retirement eligibility. 377Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Historically, Exelon has granted most of its stock options in the first quarter of each year. Stock options granted during the remainingquarters of 2012 and 2011 were not significant. The fair value of each option is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The following tablepresents the weighted average assumptions used in the pricing model for grants and the resulting weighted average grant date fair value ofstock options granted for the years ended 2012 and 2011: Year EndedDecember 31, 2012 2011 Dividend yield 5.28% 4.84% Expected volatility 23.20% 24.40% Risk-free interest rate 1.30% 2.65% Expected life (years) 6.25 6.25 Weighted average grant date fair value (per share) $4.18 $6.22 The assumptions above relate to Exelon stock options granted during the periods presented and therefore do not include stock optionsthat were converted in connection with the merger with Constellation during the year ended 2012. The dividend yield is based on several factors, including Exelon’s most recent dividend payment at the grant date and the average stockprice over the previous year. Expected volatility is based on implied volatilities of traded stock options in Exelon’s common stock and historicalvolatility over the estimated expected life of the stock options. The risk-free interest rate for a security with a term equal to the expected life isbased on a yield curve constructed from U.S. Treasury strips at the time of grant. For each year presented, the expected life represents theperiod of time the stock options are expected to be outstanding and is based on the simplified method. Exelon believes that the simplifiedmethod is appropriate due to several factors that result in historical exercise data not being sufficient to determine a reasonable estimate ofexpected term. Exelon uses historical data to estimate employee forfeitures, which are compared to actual forfeitures on a quarterly basis andadjusted as necessary.

At December 31, 2013, $2 million of total unrecognized compensation costs related to nonvested stock options are expected to berecognized over the 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 afterthe service condition has been met. The corresponding cost of services is measured based on the grant date fair value of the restricted stockunit issued. The value of the restricted stock units is expensed over the requisite service period using the straight-line method. The requisite serviceperiod for restricted stock units is generally three to five years. However, certain restricted stock unit awards become fully vested upon theemployee reaching retirement-eligibility. The value of the restricted stock units granted to retirement-eligible employees is either recognizedimmediately upon the date of grant or through the date at which the employee reaches retirement eligibility.

The one-time 2013 performance share transition awards, which provide an opportunity to earn an award contingent on companyperformance, will be settled 50% in common stock and 50% in cash, except for awards granted to executive vice presidents and higherofficers that may be settled 100% in cash if certain ownership requirements are satisfied. One-third of the award vests and is payable after aone-year performance period while the remaining two-thirds vests and is payable after a two-year performance period. The payout of the 2013 performance share awards and one-time performance share transition awards are based on the Company’sperformance against specific operational and financial goals set annually during the respective performance periods. As a result, the 2013performance share awards have been divided into equal tranches for the purpose of expense recognition as though the respective award weremultiple awards; with each tranche representing a corresponding fiscal year. The one-time performance share transition awards have alsobeen divided into multiple tranches for the purpose of expense recognition. One tranche reflects the one-third of the awards that vests and arepayable after a one-year period. The two-thirds of the one-time performance share transition awards that are subject to a two-year performanceperiod have also been divided into equal tranches; with each tranche representing a corresponding fiscal year. The grant date for each trancheof the 2013 performance share and one-time performance share transition awards is the date in which the performance goals for that fiscalyear are approved and communicated, which typically occurs at the corresponding January Compensation Committee meeting. The 2013 performance share awards and one-time performance share transition awards are recorded at fair value at the grant dates foreach tranche, with the estimated grant date fair value based on the expected payout of the award, which may range from 50% to 150% of thepayout target. The 2013 performance share awards also include a total shareholder return modifier (TSR) that may increase or decrease theaward up to 25% and an individual performance modifier (IPM) that can 380Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The one-time performance share transition award is not affected by either TSR or the IPM. The common stock portion of the performance share and one-time performance share transition awards is considered an equity awardbeing valued based on Exelon’s stock price on the grant date. The cash portion of the awards is considered a liability award which isremeasured each reporting period based on Exelon’s current stock price. As the value of the common stock and cash portions of the awardsare based on Exelon’s stock price during the performance period, coupled with changes in the total shareholder return modifier and expectedpayout of the award, the compensation costs are subject to volatility until payout is established. The 2012 performance share awards are recorded at fair value at the date of grant with the estimated grant date fair value based on theexpected payout of the award, which may range from 75% to 125% of the payout target. The common stock portion is considered an equityaward with the 75% payout floor being valued based on Exelon’s stock price on the grant date. The cash portion of the award is considered aliability award with the 75% payout floor being remeasured each reporting period based on Exelon’s current stock price. The expected payoutin excess of the 75% floor for the equity and liability portions are remeasured each reporting period based on Exelon’s current stock price andchanges in the expected payout of the award; therefore these portions of the award are subject to volatility until the payout is established. For nonretirement-eligible employees, stock-based compensation costs are recognized over the vesting period of three years using thegraded-vesting method. For performance share and one-time performance share transition awards granted to retirement-eligible employees,the value of the performance shares in recognized ratably over the vesting period, which is the year of grant.

Earnings Per Share and Equity (Exelon) Earnings per Share Diluted earnings per share is calculated by dividing net income by the weighted average number of shares of common stockoutstanding, including shares to be issued upon exercise of stock options, performance share awards and restricted stock outstanding underExelon’s LTIPs considered to be common stock equivalents. The following table sets forth the components of basic and diluted earnings pershare and shows the effect of these stock options, performance share awards and restricted stock on the weighted average number of sharesoutstanding used in calculating diluted earnings per share: Year Ended December 31, 2013 2012 2011 Net income attributable to common shareholders $1,719 $1,160 $2,495 Weighted average common shares outstanding—basic 856 816 663 Assumed exercise and/or distributions of stock-based awards 4 3 2 Weighted average common shares outstanding—diluted 860 819 665 The number of stock options not included in the calculation of diluted common shares outstanding due to their antidilutive effect wasapproximately 20 million in 2013, 14 million in 2012 and 9 million in 2011. Under share repurchase programs, 35 million shares of common stock are held as treasury stock with a cost of $2.3 billion as ofDecember 31, 2013. In 2008, Exelon management decided to defer indefinitely any share repurchases. Preferred Securities Redemption (Exelon and PECO) On May 1, 2013, PECO redeemed all of its outstanding preferred securities. PECO had $87 million of cumulative preferred securitiesthat were redeemable at its option at any time for the redemption price established when each series of securities were issued. Theredemption premium of $6 million is treated as a reduction to Net income to arrive at Net income attributable to common shareholdersutilized in the calculation of earnings per share for Exelon for the year ending December 31, 2013. As a result of the redemption, PECO isnow indirectly, wholly-owned by Exelon. 382 (a) (b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Commitments and Contingencies (Exelon, Generation, ComEd, PECO and BGE) Nuclear Insurance Generation is subject to liability, property damage and other risks associated with major incidents at any of its nuclear stations,including the CENG nuclear stations. Generation has reduced its financial exposure to these risks through insurance and other industryrisk-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 theU.S. licensed nuclear facilities and also to limit the liability of nuclear reactor owners for such claims from any single incident. As ofDecember 31, 2013, the current liability limit per incident was $13.6 billion and is subject to change to account for the effects of inflation andchanges in the number of licensed reactors. An inflation adjustment must be made at least once 384(a)(b)(b)(c)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) every 5 years and the last inflation adjustment was made effective September 10, 2013. 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 thepurchase of private nuclear energy liability insurance for public liability claims that could arise in the event of an incident. As of January 1,2013, the amount of nuclear energy liability insurance purchased is $375 million for each operating site. Additionally, the Price-Anderson Actrequires a second layer of protection through the mandatory participation in a retrospective rating plan for power reactors (currently 104reactors) resulting in an additional $13.2 billion in funds available for public liability claims. Participation in this secondary financial protectionpool requires the operator of each reactor to fund its proportionate share of costs for any single incident that exceeds the primary layer offinancial protection. Under the Price-Anderson Act, the maximum assessment in the event of an incident for each nuclear operator, perreactor, per incident (including a 5% surcharge), is $127.3 million, payable at no more than $19 million per reactor per incident per year.Exelon’s maximum liability per incident is approximately $2.4 billion. In addition, the U.S. Congress could impose revenue-raising measures on the nuclear industry to pay public liability claims exceedingthe $13.6 billion limit for a single incident. Generation is required each year to report to the NRC the current levels and sources of property insurance that demonstratesGeneration possesses sufficient financial resources to stabilize and decontaminate a reactor and reactor station site in the event of anaccident. The property insurance maintained for each facility is currently provided through insurance policies purchased from NEIL, anindustry 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 madedistributions to its members, but Generation cannot predict the level of future distributions or if they will continue at all. NEIL declared adistribution for 2013, of which Generation’s portion was $18.5 million. The distribution was recorded as a reduction to Operating andmaintenance expense within Exelon and Generation’s Consolidated Statements of Operations and Comprehensive Income. Nodistributions were declared in 2011 or 2012. Premiums paid to NEIL by its members are subject to assessment for adverse loss experience(the retrospective premium obligation). NEIL has never exercised this assessment since its formation in 1973, and while Generation cannotpredict the level of future assessments, or if they will be imposed at all, as of December 31, 2013, the current maximum aggregate annualretrospective premium obligation for Generation is approximately $287 million. NEIL provides “all risk” property damage, decontamination and premature decommissioning insurance for each station for lossesresulting from damage to its nuclear plants, either due to accidents or acts of terrorism. As of December 31, 2013, Generation’s current limitfor this coverage is $2.1 billion. For property limits in excess of the first $1.25 billion of that limit, Generation participates in an $850 millionsingle limit blanket policy shared by all the Generation operating nuclear sites and the Salem and Hope Creek nuclear sites. This blanketlimit is not subject to automatic reinstatement in the event of a loss. In the event of an accident, insurance proceeds must first be used forreactor stabilization and site decontamination. If the decision is made to decommission the facility, a portion of the insurance proceeds will beallocated to a fund, which Generation is required by the NRC to maintain, to provide for decommissioning the facility. In the event of aninsured loss, Generation is unable to predict the timing of the availability of insurance proceeds to Generation and the amount of suchproceeds that would be available. Under the terms of the various insurance agreements, Generation could be assessed up to $229 millionper year for losses incurred at any plant insured by the insurance company (the retrospective premium obligation). In the event that one ormore acts of terrorism cause accidental property damage within a twelve-month period from the first accidental 385Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) property damage under one or more policies for all insured plants, the maximum recovery for all losses by all insureds will be an aggregateof $3.2 billion plus such additional amounts as the insurer may recover for all such losses from reinsurance, indemnity and any othersource, applicable to such losses. The $3.2 billion maximum recovery limit is not applicable, however, in the event of a “certified act ofterrorism” as defined in the Terrorism Risk Insurance Act of 2002, as amended by the Terrorism Risk Insurance Program ReauthorizationAct of 2007. The Terrorism Risk Insurance Act expires on December 31, 2014. Additionally, NEIL provides replacement power cost insurance in the event of a major accidental outage at an insured nuclear station.The premium for this coverage is subject to assessment for adverse loss experience. Generation’s maximum share of any assessment is$58 million per year (the retrospective premium obligation). Recovery under this insurance for terrorist acts is subject to the $3.2 billionaggregate limit and secondary to the property insurance described above. This limit would not apply in cases of certified acts of terrorismunder the Terrorism Risk Insurance Act of 2002, as amended by the Terrorism Risk Insurance Program Reauthorization Act of 2007, asdescribed above. NEIL requires its members to maintain an investment grade credit rating or to ensure collectability of their annual retrospectivepremium obligation by providing a financial guarantee, letter of credit, deposit premium, or some other means of assurance. For its insured losses, Generation is self-insured to the extent that losses are within the policy deductible or exceed the amount ofinsurance maintained. Uninsured losses and other expenses, to the extent not recoverable from insurers or the nuclear industry, could alsobe borne by Generation. Any such losses could have a material adverse effect on Exelon’s and Generation’s financial condition, results ofoperations and liquidity. Spent Nuclear Fuel Obligation Under the NWPA, the DOE is responsible for the development of a geologic repository for and the disposal of SNF and high-levelradioactive waste. As required by the NWPA, Generation is a party to contracts with the DOE (Standard Contracts) to provide for disposal ofSNF from Generation’s nuclear generating stations. In accordance with the NWPA and the Standard Contracts, Generation pays the DOEone mill ($0.001) per kWh of net nuclear generation for the cost of SNF disposal. This fee may be adjusted prospectively in order to ensurefull cost recovery. The NWPA and the Standard Contracts required the DOE to begin taking possession of SNF generated by nucleargenerating units by no later than January 31, 1998. The DOE, however, failed to meet that deadline and its performance will be delayedsignificantly. On November 19, 2013, the United States Court of Appeals for the District of Columbia Circuit ordered the DOE to submit toCongress a proposal to reduce the current SNF disposal fee to zero, unless and until there is a viable disposal program. On January 3, 2014,the DOE filed a petition for rehearing. On the same date, as ordered by the court, the DOE submitted a proposal to Congress to reduce thecurrent SNF disposal fee to zero, subject to any further judicial decision. The DOE’s submitted proposal becomes effective after the 90-days ofcontinuous session of the Congress unless there is Congressional action contrary to the DOE proposal. However, if the court grants thepetition for rehearing, the proposal to eliminate the fee (and the review period) will be held in suspense until after the court rules. Until suchtime as a new fee structure is in effect, Generation must continue to pay the current SNF disposal fees. The 2010 Federal budget (which became effective October 1, 2009) eliminated almost all funding for the creation of the Yucca Mountainrepository while the Obama administration devised a new strategy for long-term SNF management.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Future, appointed by the U.S. Energy Secretary, released a report on January 26, 2012, detailing comprehensive recommendations forcreating a safe, long-term solution for managing and disposing of the nation’s spent nuclear fuel and high-level radioactive waste. In early 2013, the DOE issued an updated “Strategy for the Management and Disposal of Used Nuclear Fuel and High-LevelRadioactive Waste” in response to the BRC recommendations. This strategy included a consolidated interim storage facility that is planned tobe operational in 2025. Generation uses the 2025 date as the assumed date for when the DOE will begin accepting SNF for purposes of determining nucleardecommissioning asset retirement obligations. The extended delay in SNF acceptance by the DOE has led to Generation’s adoption of drycask storage at its Dresden, Clinton, Limerick, Oyster Creek, Peach Bottom, Byron, Braidwood, LaSalle and Quad Cities stations. In August 2004, Generation and the DOJ, in close consultation with the DOE, reached a settlement under which the governmentagreed to reimburse Generation, subject to certain damage limitations based on the extent of the government’s breach, for costs associatedwith storage of SNF at Generation’s nuclear stations pending the DOE’s fulfillment of its obligations. Generation submits annualreimbursement requests to the DOE for costs associated with the storage of SNF. In all cases, reimbursement requests are made only aftercosts are incurred and only for costs resulting from DOE delays in accepting the SNF. Under the settlement agreement, Generation has received cash reimbursements for costs incurred through April 30, 2013, totalingapproximately $712 million ($601 million after considering amounts due to co-owners of certain nuclear stations and to the former owner ofOyster Creek). As of December 31, 2013, the amount of SNF storage costs for which reimbursement will be requested from the DOE underthe settlement agreement is $71 million, which is recorded within Accounts receivable, other. Of this amount, $18 million representsamounts owed to the co-owners of the Peach Bottom and Quad Cities generating facilities. CENG entered into settlement agreements with the DOE during 2011 and 2012 to recover damages caused by the DOE’s failure tocomply with legal and contractual obligations to dispose of spent nuclear fuel related to the Ginna, Calvert Cliffs and Nine Mile Point nuclearpower plants. At December 31, 2012, Generation had approximately $22 million recorded as a receivable from CENG with respect to costsincurred by Constellation prior to the formation of the CENG joint venture for the Nine Mile Point and Calvert Cliffs nuclear powerplants. CENG received the funds for the Nine Mile Point and Calvert Cliffs settlement from the DOE in January 2013 and February 2013,respectively, and remitted the $22 million to Generation. The Standard Contracts with the DOE also required the payment to the DOE of a one-time fee applicable to nuclear generation throughApril 6, 1983. The fee related to the former PECO units has been paid. Pursuant to the Standard Contracts, ComEd previously elected todefer payment of the one-time fee of $277 million for its units (which are now part of Generation), with interest to the date of payment, untiljust prior to the first delivery of SNF to the DOE. As of December 31, 2013, the unfunded SNF liability for the one-time fee with interest was$1,021 million. Interest accrues at the 13-week Treasury Rate. The 13-week Treasury Rate in effect, for calculation of the interest accrual atDecember 31, 2013, was 0.051%. The liabilities for SNF disposal costs, including the one-time fee, were transferred to Generation as part ofExelon’s 2001 corporate restructuring. The outstanding one-time fee obligations for the Oyster Creek and TMI units remain with the formerowners. Clinton has no outstanding obligation.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Energy Commitments Generation’s customer facing activities include the physical delivery and marketing of power obtained through its generation capacity,and long-, intermediate- and short-term contracts. Generation maintains an effective supply strategy through ownership of generation assetsand power purchase and lease agreements. Generation has also contracted for access to additional generation through bilateral long-termPPAs. These agreements are firm commitments related to power generation of specific generation plants and/or are dispatchable in nature.Several of Generation’s long-term PPAs, which have been determined to be operating leases, have significant contingent rental paymentsthat are dependent on the future operating characteristics of the associated plants, such as plant availability. Generation recognizes contingentrental expense when it becomes probable of payment. Generation enters into PPAs with the objective of obtaining low-cost energy supplysources to meet its physical delivery obligations to its customers. Generation has also purchased firm transmission rights to ensure that ithas reliable transmission capacity to physically move its power supplies to meet customer delivery needs. The primary intent and businessobjective for the use of its capital assets and contracts is to provide Generation with physical power supply to enable it to deliver energy tomeet customer needs. In addition to physical contracts, Generation uses financial contracts for economic hedging purposes and, to a lesserextent, as part of proprietary trading activities. Generation has entered into bilateral long-term contractual obligations for sales of energy to load-serving entities, including electricutilities, municipalities, electric cooperatives and retail load aggregators. Generation also enters into contractual obligations to deliver energyto market participants who primarily focus on the resale of energy products for delivery. Generation provides for delivery of its energy to thesecustomers through firm transmission. As part of reaching a comprehensive agreement with EDF in October 2010, the existing power purchase agreements with CENG weremodified to be unit-contingent through the end of their original term in 2014. Under these agreements, CENG has the ability to fix the energyprice on a forward basis by entering into monthly energy hedge transactions for a portion of the future sale, while any unhedged portions willbe provided at market prices by default. Additionally, beginning in 2015 and continuing to the end of the life of the respective plants,Generation agreed to purchase 50.01% of the nuclear plant output owned by CENG at market prices. Generation discloses in the table belowcommitments to purchase from CENG at fixed prices. All commitments to purchase at market prices, which include all purchasessubsequent to December 31, 2014, are excluded from the table. Generation continues to own a 50.01% membership interest in CENG thatis accounted for as an equity method investment.

Construction Commitments Generation has committed to the construction of the Antelope Valley solar PV facility in Los Angeles County, California. The first portionof the project began operations in December 2012, with six additional blocks coming online in 2013 and an expectation of full commercialoperation in the first half of 2014. Generation’s estimated remaining commitment for the project is $110 million. On July 3, 2013, Generation executed a Turbine Supply Agreement to expand its Beebe wind project in Michigan. The estimatedremaining commitment under the contract is $50 million and achievement of commercial operations is expected in 2014. On July 26, 2013, Generation executed an engineering procurement and construction contract to expand its Perryman, Marylandgeneration site with 120 MW of new natural gas-fired generation to satisfy certain merger commitments. The estimated remainingcommitment under the contract is $80 million and achievement of commercial operation is expected in 2015. See 4—Merger andAcquisitions for additional information on commitments to develop or assist in development of new generation in Maryland resulting fromthe merger.

Indemnifications Related to Sale of Sithe (Exelon and Generation) On January 31, 2005, subsidiaries of Generation completed a series of transactions that resulted in Generation’s sale of its investmentin Sithe. Specifically, subsidiaries of Generation consummated the acquisition of Reservoir Capital Group’s 50% interest in Sithe andsubsequently sold 100% of Sithe to Dynegy Inc. (Dynegy). The estimated maximum possible exposure to Exelon related to the guarantees provided as part of the sales transaction to Dynegy wasapproximately $200 million at December 31, 2013. Generation believes that it is remote that it will be required to make any additionalpayments under the guarantee, and currently has no recorded liabilities associated with this guarantee. Generation expects that the exposurecovered by this guarantee will expire in 2014.

(TII), a wholly owned subsidiary of Generation, sold its 49.5% ownership interests inTEG and TEP to a subsidiary of AES Corporation for $95 million in cash plus certain purchase price adjustments. In connection with thetransaction, Generation entered into a guarantee agreement under which Generation guarantees the timely payment of TII’s obligations tothe subsidiary of AES Corporation pursuant to the terms of the purchase and sale agreement relating to the sale of TII’s ownership interests.Generation was required to perform in the event that TII did not pay any obligation covered by the guarantee that was not otherwise subject toa dispute resolution process. Portions of the exposures covered by this guarantee expired in 2008, and the remaining guarantee expired inthe third quarter of 2013. Generation was not required to make payments under the guarantee, and therefore, has no further obligationrelated to this guarantee as of December 31, 2013. Environmental Matters General. The Registrants’ operations have in the past, and may in the future, require substantial expenditures in order to comply withenvironmental laws. Additionally, under Federal and state environmental laws, the Registrants are generally liable for the costs ofremediating environmental contamination of property currently or formerly owned by them and of property contaminated by hazardoussubstances generated by them. The Registrants own or lease a number of real estate parcels, including parcels on which their operations orthe operations of others may have resulted in contamination by substances that are considered hazardous under environmental laws. Inaddition, the Registrants are currently involved in a number of proceedings relating to sites where hazardous substances have beendeposited and may be subject to additional proceedings in the future. ComEd, PECO and BGE have identified sites where former MGP activities have or may have resulted in actual site contamination.For many of these sites, ComEd, PECO or BGE is one of several PRPs that may be responsible for ultimate remediation of each location. • ComEd has identified 42 sites, 16 of which have been approved for cleanup by the Illinois EPA or the U.S. EPA and 26 that arecurrently under some degree of active study and/or remediation. ComEd expects the majority of the remediation at these sites tocontinue through at least 2016. • PECO has identified 26 sites, 16 of which have been approved for cleanup by the PA DEP and 10 that are currently under somedegree of active study and/or remediation. PECO expects the majority of the remediation at these sites to continue through at least2020. • BGE has identified 13 former gas manufacturing or purification sites that it currently owns or owned at one time through apredecessor’s acquisition. Two gas manufacturing sites require some level of remediation and ongoing monitoring under thedirection of the MDE. The required costs at these two sites are not considered material. One gas purification site is in the initialstages of investigation at the direction of the MDE. ComEd, pursuant to an ICC order, and PECO, pursuant to settlements of natural gas distribution rate cases with the PAPUC, arecurrently recovering environmental remediation costs of former MGP facility sites through customer rates. BGE is authorized to and iscurrently recovering environmental costs for the remediation of former MGP facility sites from customers; however, while BGE does nothave a rider for MGP clean-up costs, BGE has historically received recovery of actual clean-up costs in distribution rates. ComEd, PECO andBGE have recorded regulatory assets for the recovery of these 395Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

During the third quarter of 2013, ComEd and PECO completed an annual study of their future estimated MGP remediationrequirements. The results of these studies indicated that additional remediation would be required at certain sites; accordingly, ComEd andPECO increased their reserves and regulatory assets by less than $1 million and $6 million, respectively. BGE assessed its currently andformerly owned gas manufacturing and purification sites quarterly in 2013 and determined that a loss was not probable at ten of its sites as ofDecember 31, 2013. As discussed above, the remediation costs at two of BGE’s MGP sites are not considered material. Furthermore, anestimate of a range of possible loss, if any, related to BGE’s gas purification site under investigation cannot be determined as ofDecember 31, 2013 given that the site is in the early stages of investigation and the extent of contamination is currently unknown. See Note3—Regulatory Matters for additional information regarding the associated regulatory assets. The historical nature of the MGP sites and the fact that many of the sites have been buried and built over, impacts the ability todetermine a precise estimate of the ultimate costs prior to initial sampling and determination of the exact scope and method of remedialaction. Management determines its best estimate of remediation costs based on probabilistic modeling and deterministic estimates using allavailable information at the time of each study and the remediation standards currently required by the U.S. EPA. Prior to completion of anysignificant clean up, each site remediation plan is approved by the appropriate state environmental agency. As of December 31, 2013 and 2012, the Registrants have accrued the following undiscounted amounts for environmental liabilities inother current liabilities and other deferred credits and other liabilities within their respective Consolidated Balance Sheets: December 31, 2013 Total environmentalinvestigationand remediation reserve Portion of total related to MGPinvestigation and remediation Exelon $338 $273 Generation 56 — ComEd 234 229 PECO 47 44 BGE 1 — December 31, 2012 Total environmentalinvestigationand remediation reserve Portion of total related to MGPinvestigation and remediation Exelon $351 $298 Generation 42 — ComEd 261 254 PECO 47 44 BGE 1 — The Registrants cannot reasonably estimate whether they will incur other significant liabilities for additional investigation andremediation costs at these or additional sites identified by the Registrants, environmental agencies or others, or whether such costs will berecoverable from third parties, including customers. Water Quality Section 316(b) of the Clean Water Act. Section 316(b) requires that the cooling water intake structures at electric power plants reflectthe best technology available to minimize adverse environmental impacts, and is implemented through state-level NPDES permit programs.All of 396Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Generation’s and CENG’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 changes to the existing regulations. For Generation, thosefacilities are Clinton, Dresden, Eddystone, Fairless Hills, Gould Street, Handley, Mountain Creek, Mystic 7, Oyster Creek, Peach Bottom,Quad Cities, Riverside, Salem and Schuylkill. For CENG, those facilities are Calvert Cliffs, Nine Mile Point Unit 1 and R.E. Ginna. On March 28, 2011, the U.S. EPA issued the proposed regulation under Section 316(b). The proposal does not require closed-cyclecooling (e.g., cooling towers) as the best technology available to address impingement and entrainment. The proposal provides the statepermitting agency with discretion to determine the best technology available to limit entrainment (drawing aquatic life into the plants coolingsystem) mortality, including application of a cost-benefit test and the consideration of a number of site-specific factors. After consideration ofthese factors, the state permitting agency may require closed cycle cooling, an alternate technology, or determine that the current technologyis the best available. The proposed rule also imposes limits on impingement (trapping aquatic life on screens) mortality, which likely will beaccomplished by the installation of screens or another technology at the intake. Exelon filed comments on the proposed regulation onAugust 18, 2011, stating its support for a number of its provisions (e.g., cooling towers not required as best technology available, and the useof site-specific and cost benefit analysis) while also noting a number of technical provisions that require revision to take into account existingunit operations and practices within the industry. In June 2012, the U.S. EPA published two Notices of Data Availability (NODA) seeking public comment on alternate compliancetechnologies for impingement and the use of a public opinion survey to calculate the so-called “non-use” benefits of the rule. Exelon filedcomments for each NODA, supporting the additional flexibility afforded by the impingement NODA, and opposing the NODA relating tocalculation of non-use benefits due to its inaccurate and unreliable methodologies that would artificially inflate the benefits of proposedtechnologies that would otherwise not be cost-effective. On June 27, 2013, the U.S. EPA agreed to amend the court approved SettlementAgreement to extend the deadline to issue a final rule until November 4, 2013 and on October 30, 2013 the U.S. EPA invoked the forcemajeure provision of the Settlement Agreement to extend the final rule deadline until January 14, 2014 due to the early October 2013 federalgovernment shutdown. The U.S. EPA and the plaintiffs have again agreed to extend the date for issuance of the final rule until April 17, 2014.Until the rule is finalized, the state permitting agencies will continue to apply their best professional judgment to address impingement andentrainment. Salem and Other Power Generation Facilities. In June 2001, the NJDEP issued a renewed NPDES permit for Salem, allowing forthe continued operation of Salem with its existing cooling water system. NJDEP advised PSEG, in July 2004 that it strongly recommendedreducing cooling water intake flow commensurate with closed-cycle cooling as a compliance option for Salem. PSEG submitted anapplication for a renewal of the permit on February 1, 2006. In the permit renewal application, PSEG analyzed closed-cycle cooling and otheroptions and demonstrated that the continuation of the Estuary Enhancement Program, an extensive environmental restoration program atSalem, is the best technology to meet the Section 316(b) requirements. PSEG continues to operate Salem under the approved June 2001NPDES permit while the NPDES permit renewal application is being reviewed. If the final permit or Section 316(b) regulations ultimatelyrequires the retrofitting of Salem’s cooling water intake structure to reduce cooling water intake flow commensurate with closed-cycle cooling,Exelon’s and Generation’s share of the total cost of the retrofit and any resulting interim replacement power would likely be in excess of $430million, based on a 2006 estimate, and would result in increased depreciation expense related to the retrofit investment. 397Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) It is unknown at this time whether the NJDEP permit programs will require closed-cycle cooling at Salem. In addition, the economicviability of Generation’s other power generation facilities, as well as CENG’s, without closed-cycle cooling water systems will be called intoquestion by any requirement to construct cooling towers. Should the final rule not require the installation of cooling towers, and retain theflexibility afforded the state permitting agencies in applying a cost benefit test and to consider site-specific factors, the impact of the rule wouldbe minimized even though the costs of compliance could be material to Generation and CENG. Given the uncertainties associated with the requirements that will be contained in the final rule, Generation cannot predict the eventualoutcome or estimate the effect that compliance with any resulting Section 316(b) or interim state requirements will have on the operation ofits and CENG’s generating facilities and its future results of operations, cash flows and financial position. Groundwater Contamination. In October 2007, a subsidiary of Constellation entered into a consent decree with the MDE relating togroundwater contamination at a third-party facility that was licensed to accept fly ash, a byproduct generated by coal-fired plants. The consentdecree required the payment of a $1 million penalty, remediation of groundwater contamination resulting from the ash placement operationsat the site, replacement of drinking water supplies in the vicinity of the site, and monitoring of groundwater conditions. Prior to the Merger,Constellation recorded in its Consolidated Balance Sheets total liabilities of approximately $30 million to comply with the consent decree withan additional $3 million recognized through purchase accounting. During third quarter of 2013, Generation increased its reserve by $2million based on an update of future estimated remediation costs. The remaining liability as of December 31, 2013, is approximately$14 million. In addition, a private party asserted claims relating to groundwater contamination. Generation has reached an agreement inprinciple to resolve these claims. The amount of the settlement is not material to the financial condition of Generation. Alleged Conemaugh Clean Streams Act Violation. The PA DEP has alleged that GenOn Northeast Management Company(GenOn), the operator of Conemaugh Generating Station, violated the Pennsylvania Clean Streams Law. GenOn reached agreement withPA DEP on a proposed Consent Decree that was approved by the Commonwealth Court of Pennsylvania on December 4, 2012. Under theConsent Decree, GenOn is obligated to pay a civil penalty of $0.5 million, of which Generation’s responsibility was approximately $0.2million. Generation made the final payment in January 2014 and is complying with the Consent Decree. Air Quality Cross-State Air Pollution Rule (CSAPR). On July 11, 2008, the U.S. Court of Appeals for the District of Columbia Circuit (D.C.Circuit Court) vacated the CAIR, which had been promulgated by the U.S. EPA to reduce power plant emissions of SO and NO. The D.C.Circuit Court later remanded the CAIR to the U.S. EPA, without invalidating the entire rulemaking, so that the U.S. EPA could correct CAIRin accordance with the D.C. Circuit Court’s July 11, 2008 opinion. On July 7, 2011, the U.S. EPA published the final rule, known as theCSAPR. The CSAPR requires 28 states in the eastern half of the United States to significantly improve air quality by reducing power plantemissions that cross state lines and contribute to ground-level ozone and fine particle pollution in other states. Numerous entities challenged the CSAPR in the D.C. Circuit Court, and some requested a stay of the rule pending the Court’sconsideration of the matter on the merits. On December 30, 2011, the Court granted a stay of the CSAPR, and directed the U.S. EPA tocontinue the administration of CAIR in the interim. On August 21, 2012, a three-judge panel of the D.C. Circuit Court held that the U.S. EPA 3982xSource: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) has exceeded its authority in certain material aspects of the CSAPR and vacated the rule and remanded it to the U.S. EPA for furtherrulemaking consistent with its decision. The Court also ordered that CAIR remain in effect pending finalization of CSAPR on remand. TheCourt’s order was appealed to the U.S. Supreme Court, where oral argument was held on December 10, 2013. A decision is expectedsometime during 2014. Under the CSAPR, generation units were to receive allowances based on historic heat input and intrastate, and limited interstate,trading of allowances was permitted. The CSAPR restricted entirely the use of pre-2012 allowances. Existing SO allowances under the ARPwould remain available for use under ARP. As of December 31, 2013, Generation had $56 million of emission allowances carried at thelower of weighted average cost or market. EPA Mercury and Air Toxics Standards (MATS). The MATS rule became final on April 16, 2012. The MATS rule reducesemissions of toxic air pollutants, and finalized the new source performance standards for fossil fuel-fired electric utility steam generating units(EGUs). The MATS rule requires coal-fired EGUs to achieve high removal rates of mercury, acid gases and other metals from air emissions.To achieve these standards, coal units with no pollution control equipment installed (uncontrolled coal units) will have to make capitalinvestments and incur higher operating expenses. It is expected that smaller, older, uncontrolled coal units will retire rather than make theseinvestments. Coal units with existing controls that do not meet the required standards may need to upgrade existing controls or add newcontrols to comply. In addition, the new standards will require oil units to achieve high removal rates of metals. Owners of oil units notcurrently meeting the proposed emission standards may choose to convert the units to light oils or natural gas, install control technologies orretire the units. The MATS rule requires generating stations to meet the new standards three years after the rule takes effect, April 16, 2015,with specific guidelines for an additional one or two years in limited cases. Numerous entities have challenged MATS in the D.C. CircuitCourt, and Exelon was granted permission by the Court to intervene in support of the rule. A decision by the Court is expected sometimeduring 2014. The outcome of the appeal, and its impact on power plant operators’ investment and retirement decisions, is uncertain. Exelon, along with the other co-owners of Conemaugh Generating Station are moving forward with plans to improve the existingscrubbers and install Selective Catalytic Reduction (SCR) controls to meet the mercury removal requirements of MATS. In addition, as of December 31, 2013, Exelon had a $698 million net investment in coal-fired plants in Georgia and Texas subject tolong-term leases extending through 2028-2032. While Exelon currently estimates the value of these plants at the end of the lease term willbe in excess of the recorded residual lease values, after the impairment recorded in the second quarter of 2013, final applications of theCSAPR and MATS regulations could negatively impact the end-of-lease term values of these assets, which could result in a futureimpairment loss that could be material. National Ambient Air Quality Standards (NAAQS). The U.S. EPA previously announced that it would complete a review of allNAAQS by 2014. Oral argument in the litigation (State of Miss. v. EPA) of the final 2008 ozone standard occurred in the D.C. Circuit Court inNovember 2012 and a final Court decision was issued on July 23, 2013 with the 2008 primary ozone standard upheld, but the secondarystandard remanded to EPA for reconsideration. Concurrent with litigation of the 2008 ozone standard, the U.S. EPA continues its regular,periodic review of the ozone NAAQS and is expected to propose revisions in the fall of 2014, with preliminary indications that the U.S. EPAwill likely propose a tightened standard. It is unclear at this point in time whether the U.S. EPA will be able to respond to the Court remand ofthe secondary 2008 ozone standard on a timeframe that would be any quicker than 3992Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) that of the U.S. EPA’s current, periodic review schedule. In December 2012, the U.S. EPA issued its final revisions to the Agency’sparticulate matter (PM) NAAQS. In its final rule, the U.S. EPA lowered the annual PM2.5 standard, but declined to issue a new secondaryNAAQS to improve urban visibility. The U.S. EPA indicated in its final rule that by 2020 it expects most areas of the country will be inattainment of the new PM2.5 NAAQS based on currently expected regulations, such as the MATS regulation. It is unclear if the vacatur of theCSAPR, one of the regulations that the U.S. EPA is relying on to assist with future PM reduction, would alter the U.S. EPA’s view sinceeither CAIR or a finalized CSAPR regulation would be in effect leading up to 2020. In March 2013, a number of industry coalitions filed ajoint lawsuit challenging the new PM2.5 standard. Also during early 2013, the D.C. Circuit remanded several rules for implementation ofearlier PM2.5 NAAQS to the U.S. EPA for revision of certain aspects of the rules, with a requirement that the U.S. EPA re-promulgateregulations in conformance with the correct subparts of the Clean Air Act. In addition to these NAAQS, the U.S. EPA also finalized nonattainment designations for certain areas in the United States for the 2010one-hour SO standard on August 5, 2013, and indicated that additional nonattainment areas will be designated in a future rulemaking. U.S.EPA will require states to submit state implementation plans (SIPs) for nonattainment areas by April 2015. With regard to Texas andMaryland, no nonattainment areas were identified in U.S. EPA’s final designation rule. With regard to Illinois and Pennsylvania, severalcounties, or portions of counties, in each state were identified as nonattainment. The U.S. EPA will follow the approach outlined in aFebruary 2013 U.S. EPA strategy document that establishes a process and timeline for the Agency to address additional designations instates’ counties under a future rulemaking. Nonattainment county compliance with the one-hour SO standard is required by October 2018.While significant SO reductions will occur as a result of MATS compliance in 2015, Exelon is unable to predict the requirements of pendingstates’ SIPs to further reduce SO emissions in support of attainment of the one hour SO standard. Notices and Finding of Violations and Midwest Generation Bankruptcy. In December 1999, ComEd sold several generatingstations to Midwest Generation, LLC (Midwest Generation), a subsidiary of Edison Mission Energy (EME). Under the terms of the saleagreement, Midwest Generation and EME assumed responsibility for environmental liabilities associated with the ownership, occupancy,use and operation of the stations, including responsibility for compliance by the stations with environmental laws before their purchase byMidwest Generation. Midwest Generation and EME additionally agreed to indemnify and hold ComEd and its affiliates harmless fromclaims, fines, penalties, liabilities and expenses arising from third-party claims against ComEd resulting from or arising out of theenvironmental liabilities assumed by Midwest Generation and EME under the terms of the agreement governing the sale. In connection withExelon’s 2001 corporate restructuring, Generation assumed ComEd’s rights and obligations with respect to its former generation business,including its rights and obligations under the sale agreement with Midwest Generation and EME. On December 17, 2012 (Petition Date), EME and certain of its subsidiaries, including Midwest Generation, filed for protection underChapter 11 of the U.S. Bankruptcy Code. In 2012, the Bankruptcy Court approved the rejection of a coal rail car lease under which Midwest Generation had agreed to reimburseComEd for all obligations. The rejection left Generation as the party responsible to make remaining payments under the lease. In January2013, Generation made the final $10 million payment due under the lease agreement which had been accrued at December 31, 2012. 40022222Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) During the second quarter of 2013, Exelon filed proofs of claim of $21 million with the Bankruptcy Court for amounts owed by EMEand Midwest Generation for the coal rail car lease, ComEd utility payments and certain legal costs. Further, Exelon filed an environmentalclaim with an unspecified amount that listed the indemnifications that were in place pre-Petition Date and other factors associated with theremediation. As of December 31, 2013, Exelon has not recorded a receivable for the filed proofs of claim because recovery of any amountcannot be assured at this point in the bankruptcy. Exelon will not record claim recoveries unless and until they are realized. Certain environmental laws and regulations subject current and prior owners of properties or generators of hazardous substances atsuch properties to liability for remediation costs of environmental contamination. As a prior owner of the generating stations, ComEd (andGeneration, through its agreement in Exelon’s 2001 corporate restructuring to assume ComEd’s rights and obligations associated with itsformer generation business) could face liability (along with any other potentially responsible parties) for environmental conditions at thestations requiring remediation, with the determination of the allocation among the parties subject to many uncertain factors, including theimpact of Midwest Generation’s bankruptcy. On January 17, 2014, Midwest Generation filed a plan supplement to its bankruptcy filing thatincluded a request to reject the sale agreement, including the environmental indemnity. ComEd and Generation have reviewed availablepublic information as to potential environmental exposures regarding the Midwest Generation station sites. Midwest Generation publiclydisclosed in its quarter ending September 30, 2013 Form 10-Q that (i) it has accrued a probable amount of approximately $8 million forestimated environmental investigation and remediation costs under CERCLA, or similar laws, for the investigation and remediation ofcontaminated property at four Midwest Generation plant sites, (ii) it has identified stations for which a reasonable estimate for investigationand/ or remediation cannot be made and (iii) it and the Illinois EPA entered into Compliance Commitment Agreements outlining specifiedenvironmental remediation measures and groundwater monitoring activities to be undertaken at its Crawford, Powerton, Joliet, Will Countyand Waukegan generating stations. At this time, however, ComEd and Generation do not have sufficient information to reasonably assessthe potential likelihood or magnitude of any remediation requirements that may be asserted. For these reasons, ComEd and Generation areunable to predict whether and to what extent they may ultimately be held responsible for remediation and other costs relating to thegenerating stations and as a result no liability has been recorded as of December 31, 2013. Any liability imposed on ComEd or Generationfor environmental matters relating to the generating stations could have a material adverse impact on their future results of operations andcash flows. Under a supplemental agreement reached in 2003, Midwest Generation agreed to reimburse ComEd and Generation for 50% of thespecific asbestos claims pending as of February 2003 and related expenses less recovery of insurance costs and agreed to a sharingarrangement for liabilities and expenses associated with future asbestos-related claims as specified in the agreement. In addition to the saleagreement, Midwest Generation also requested to reject this supplemental agreement in the January 17, 2014 plan supplement to itsbankruptcy filing. Exelon and Generation had previously expected Midwest Generation or its successor would remain responsible forasbestos personal injury claims filed post-Petition Date, and as a result had not recorded a liability for such amounts. Exelon and Generationnow believe that the rejection of the 1999 sale and supplemental agreements is probable, and as a result, Generation has increased itsreserve for asbestos-related bodily injury claims at December 31, 2013 by $25 million. The increase in the reserve was estimated usingactuarial assumptions and analyses available to Generation. Generation’s exposure could differ to the extent new information is received ormade available. Midwest Generation publicly disclosed in its quarter ending September 30, 2013 Form 10-Q that they had $53 millionrecorded related to asbestos bodily injury claims under the contractual indemnity with ComEd. If the agreements are rejected, Exelon and 401Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

These amounts are considered to be contingent gainsand would not be recognized until realized. On October 18, 2013, NRG Energy entered into an agreement to buy EME’s portfolio of generation subject to regulatory approvals.Exelon continues to monitor all aspects of the bankruptcy; the proposed purchase by NRG has not impacted any accounting conclusions asof December 31, 2013. In May 2010, the United States and State of Illinois initiated a lawsuit against Midwest Generation, ComEd and EME alleging Clean AirAct violations relating to the modification and/or operation of six (coal) electric generation plants in Northern Illinois, which ComEd sold toMidwest Generation/EME in 1999. The government parties sought injunctive relief and civil penalties against all defendants, although not allof the claims specifically pertained to ComEd. On March 16, 2011, the District Court granted ComEd’s motion to dismiss the May 2010complaint in its entirety as it relates to ComEd. On January 3, 2012, upon leave of the District Court, the government parties appealed thedismissal of ComEd to the U.S. Circuit Court of Appeals for the Seventh Circuit. On July 8, 2013, the Circuit Court affirmed the DistrictCourt’s dismissal of the complaint against ComEd. On September 19, 2013, the Circuit Court denied the petition for a rehearing filed by thegovernmental parties. The government parties did not seek United States Supreme Court review of the Seventh Circuit’s decision. Thedeadline for seeking such review was in December 2013. In light of the Circuit Court decision resolving this matter in favor of ComEd, noreserve has been established. Solid and Hazardous Waste Cotter Corporation. The U.S. EPA has advised Cotter Corporation (Cotter), a former ComEd subsidiary, that it is potentially liable inconnection with radiological contamination at a site known as the West Lake Landfill in Missouri. On February 18, 2000, ComEd sold Cotterto an unaffiliated third-party. As part of the sale, ComEd agreed to indemnify Cotter for any liability arising in connection with the West LakeLandfill. In connection with Exelon’s 2001 corporate restructuring, this responsibility to indemnify Cotter was transferred to Generation. OnMay 29, 2008, the U.S. EPA issued a Record of Decision approving the remediation option submitted by Cotter and the two other PRPs thatrequired additional landfill cover. The current estimated cost of the anticipated landfill cover remediation for the site is approximately $42million, which will be allocated among all PRPs. Generation has accrued what it believes to be an adequate amount to cover its anticipatedshare of such liability. By letter dated January 11, 2010, the U.S. EPA requested that the PRPs perform a supplemental feasibility study for aremediation alternative that would involve complete excavation of the radiological contamination. On September 30, 2011, the PRPssubmitted the final supplemental feasibility study to the U.S. EPA for review. In June 2012, the U.S. EPA requested that the PRPs performadditional analysis and groundwater sampling as part of the supplemental feasibility study that could take up to one year to complete, andsubsequently requested additional analysis sampling and modeling to be conducted into 2014. In light of these additional requests, it isunknown when the U.S EPA will propose a remedy for public comment. Thereafter the U.S. EPA will select a final remedy and enter into aConsent Decree with the PRPs to effectuate the remedy. A complete excavation remedy would be significantly more expensive than thepreviously selected additional cover remedy; however, Generation believes the likelihood that the U.S. EPA would require a completeexcavation remedy is remote. On August 8, 2011, Cotter was notified by the DOJ that Cotter is considered a PRP with respect to the government’s clean-up costs forcontamination attributable to low level radioactive residues at a former storage and reprocessing facility named Latty Avenue near St. Louis,Missouri. The Latty 402Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Avenue site is included in ComEd’s indemnification responsibilities discussed above as part of the sale of Cotter. The radioactive residueshad been generated initially in connection with the processing of uranium ores as part of the U.S. government’s Manhattan Project. Cotterpurchased the residues in 1969 for initial processing at the Latty Avenue facility for the subsequent extraction of uranium and metals. In1976, the NRC found that the Latty Avenue site had radiation levels exceeding NRC criteria for decontamination of land areas. Latty Avenuewas investigated and remediated by the United States Army Corps of Engineers pursuant to funding under the Formerly Utilized SitesRemedial Action Program. The DOJ has not yet formally advised the PRPs of the amount that it is seeking, but it is believed to beapproximately $90 million. The DOJ and the PRPs agreed to toll the statute of limitations until August 2014 so that settlement discussionscould proceed. Based on Exelon’s preliminary review, it appears probable that Exelon has liability to Cotter under the indemnificationagreement and has established an appropriate accrual for this liability. On February 28, 2012, and April 12, 2012, two lawsuits were filed in the U.S. District Court for the Eastern District of Missouri against15 and 14 defendants, respectively, including Exelon, Generation and ComEd (the “Exelon defendants”) and Cotter. The suits allege thatindividuals living in the North St. Louis area developed some form of cancer due to the defendants’ negligent or reckless conduct inprocessing, transporting, storing, handling and/or disposing of radioactive materials. Plaintiffs have asserted claims for negligence, strictliability, emotional distress, medical monitoring, and violations of the Price-Anderson Act. The complaints do not contain specific damageclaims. On May 30, 2012, the plaintiffs filed voluntary motions to dismiss the Exelon defendants from both lawsuits which weresubsequently granted. Since May 30, 2012, several related lawsuits have been filed in the same court on behalf of various plaintiffs againstCotter and other defendants, but not Exelon. The allegations in these related lawsuits mirror the initially filed lawsuits. In the event of afinding of liability, it is reasonably possible that Exelon would be considered liable due to its indemnification responsibilities of Cotterdescribed above. On March 27, 2013, the U.S. District Court dismissed all state common law actions brought under the initial two lawsuits;and also found that the plaintiffs had not properly brought the actions under the Price-Anderson Act. On July 8, 2013, the plaintiffs filedamended complaints under the Price-Anderson Act. Cotter moved to dismiss the amended complaints and has motions currently pendingbefore the court. At this stage of the litigation, Exelon cannot estimate a range of loss, if any. 68th Street Dump. In 1999, the U.S. EPA proposed to add the 68th Street Dump in Baltimore, Maryland to the Superfund NationalPriorities List, and notified BGE and 19 others that they are PRPs at the site. In March 2004, BGE and other PRPs formed the 68th StreetCoalition and entered into consent order negotiations with the U.S. EPA to investigate clean-up options for the site under the SuperfundAlternative Sites Program. In May 2006, a settlement among the U.S. EPA and 19 of the PRPs, including BGE, with respect to investigationof the site became effective. The settlement requires the PRPs, over the course of several years, to identify contamination at the site andrecommend clean-up options. The PRPs submitted their investigation of the range of clean-up options in the first quarter of 2011. Althoughthe investigation and options provided to the U.S. EPA are still subject to U.S. EPA review and selection of a remedy, the range of estimatedclean-up costs to be allocated among all of the PRPs is in the range of $50 million to $64 million. On September 30, 2013, U.S. EPA issuedthe Record of Decision identifying its preferred remedial alternative for the site. The estimated cost for the alternative chosen by U.S. EPA isconsistent with the PRPs estimated range of costs noted above. Based on Exelon’s preliminary review, it appears probable that Exelon hasliability and has established an appropriate accrual for its share of the estimated clean-up costs. BGE is indemnified by a wholly ownedsubsidiary of Generation for most of the costs related to this settlement and clean-up of the site. 403Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The Rossville Ash Site is a 32-acre property located in Rosedale, Baltimore County, Maryland, which was usedfor the placement of fly ash from 1983-2007. The property is owned by Constellation Power Source Generation, LLC(CPSG). In 2008,CPSG investigated and remediated the property by entering it into the Maryland Voluntary Cleanup Program (VCP) to address any historicenvironmental concerns and ready the site for appropriate future redevelopment. The site was accepted into the program in 2010 and iscurrently going through the process to remediate the site and receive closure from MDE. Exelon currently estimates the cost to close the siteto be approximately $6 million, which has been fully reserved as of December 31, 2013. Sauer Dump. On May 30, 2012, BGE was notified by the U.S. EPA that it is considered a PRP at the Sauer Dump Superfund site inDundalk, Maryland. The U.S. EPA offered BGE and three other PRPs the opportunity to conduct an environmental investigation and presentcleanup recommendations at the site. In addition, the U.S. EPA is seeking recovery from the PRPs of $1.7 million for past cleanup andinvestigation costs at the site. On March 11, 2013, BGE and three other PRP’s signed an Administrative Settlement Agreement and Orderon Consent with the U.S. EPA which requires the PRP’s to conduct a Remedial Investigation and Feasibility Study at the site to determinewhat, if any, are the appropriate and recommended cleanup activities for the site. The ultimate outcome of this proceeding is uncertain. Sincethe U.S. EPA has not selected a cleanup remedy and the allocation of the cleanup costs among the PRPs has not been determined, anestimate of the range of BGE’s reasonably possible loss, if any, cannot be determined. Climate Change Regulation. Exelon is subject to climate change regulation or legislation at the Federal, regional and state levels. In2007, the U.S. Supreme Court ruled that GHG emissions are pollutants subject to regulation under the new motor vehicle provisions of theClean Air Act. Consequently, on December 7, 2009, the U.S. EPA issued an endangerment finding under Section 202 of the Clean Air Actregarding GHGs from new motor vehicles and on April 1, 2010 issued final regulations limiting GHG emissions from cars and light truckseffective on January 2, 2011. While such regulations do not specifically address stationary sources, such as a generating plant, it is the U.S.EPA’s position that the regulation of GHGs under the mobile source provisions of the Clean Air Act has triggered the permitting requirementsunder the Prevention of Significant Deterioration (PSD) and Title V operating permit sections of the Clean Air Act for new and modifiedstationary sources effective January 2, 2011. Therefore, on May 13, 2010, the U.S. EPA issued final regulations (the Tailoring Rule) relatingto these provisions of the Clean Air Act for major stationary sources of GHG emissions that apply to new sources that emit greater than100,000 tons per year, on a CO equivalent basis, and to modifications to existing sources that result in emissions increases greater than75,000 tons per year on a CO equivalent basis. These thresholds became effective January 2, 2011, apply for six years and will be reviewedby the U.S. EPA for future applicability thereafter. On July 2, 2012 the U.S. EPA declined to lower GHG permit thresholds in its final “Step 3”Tailoring Rule update. The U.S. EPA will review permit thresholds again in a 2015 rulemaking process. On June 26, 2012, the UnitedStates Court of Appeals for the District of Columbia, in a per curium decision, dismissed industry and state petitions challenging the U.S.EPA’s “Tailpipe Rule” for cars and light duty trucks, the endangerment finding for GHG’s from stationary sources, and the Tailoring Rule. OnOctober 15, 2013 the U.S. Supreme Court granted industry petitions to review one aspect of the PSD permitting regulations. Under the PSDregulations, new and modified major stationary sources could be required to install best available control technology, to be determined on acase by case basis. Generation could be significantly affected by the regulations if it were to build new plants or modify existing plants.

Concurrent withthe announcement of the Administration’s plan, the President also issued a Memorandum for the Administrator of the EnvironmentalProtection Agency that focused on power generation sector carbon reductions under the Section 111 New Source Performance Standards(NSPS) section of the federal Clean Air Act. The memorandum directs the U.S. EPA Administrator to issue two sets of proposed rulemakingswith regard to power plant carbon emissions under Section 111 of the Clean Air Act. The first rulemaking, under Section 111(b) of the Clean Air Act is to focus on establishing carbon regulations for new fossil-fuel powerplants. This rulemaking was proposed on September 20, 2013 and is to be finalized “in a timely fashion.” In the proposed rule U.S.EPA setsseparate standards for fossil-fuel fired utility boilers and natural gas fired stationary combustion turbines. The second rulemaking, under Section 111(d) of the Clean Air Act is to focus on modified, reconstructed and existing fossil power plants.The rulemaking is to be proposed no later than June 1, 2014, be finalized no later than June 1, 2015, and require that states submit to U.S.EPA their implementation plans no later than June 30, 2016. In developing this rulemaking, U.S. EPA is directed to consider a number offactors, including options to reduce costs, options to ensure the continued use of a range of energy sources and technologies, options that areconsistent with reliable and affordable power, and options that allow for the use of market-based instruments, performance standards andother regulatory flexibilities. To the extent that the final Section 111(d) rule results in emission reductions from fossil fuel fired plants, and thereby imposes someform of direct or indirect price of carbon in competitive electricity markets, Exelon’s overall low-carbon generation portfolio results couldbenefit. Litigation and Regulatory Matters Asbestos Personal Injury Claims (Exelon, Generation, PECO and BGE). Exelon and Generation. Generation maintains a reserve for claims associated with asbestos-related personal injury actions in certainfacilities that are currently owned by Generation or were previously owned by ComEd and PECO. The reserve is recorded on anundiscounted basis and excludes the estimated legal costs associated with handling these matters, which could be material. At December 31, 2013 and 2012, Generation had reserved approximately $90 million and $63 million, respectively, in total forasbestos-related bodily injury claims. As of December 31, 2013, approximately $19 million of this amount related to 224 open claimspresented to Generation, while the remaining $71 million of the reserve is for estimated future asbestos-related bodily injury claimsanticipated to arise through 2050, based on actuarial assumptions and analyses, which are updated on an annual basis. On a quarterlybasis, Generation monitors actual experience against the number of forecasted claims to be received and expected claim payments andevaluates whether an adjustment to the reserve is necessary. On November 22, 2013, the Supreme Court of Pennsylvania held that the Pennsylvania Workers Compensation Act does not apply toan employee’s disability or death resulting from occupational disease, such as diseases related to asbestos exposure, which manifests morethan 300 weeks after the employee’s last employment-based exposure, and that therefore the exclusivity provision of the Act does not applyto preclude such employee from suing his or her employer in court.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Court’s ruling reverses previous rulings by the Pennsylvania Superior Court precluding current and former employees from suing theiremployers in court, despite the fact that the same employee was not eligible for workers compensation benefits for diseases that manifestmore than 300 weeks after the employee’s last employment-based exposure to asbestos. Currently, Exelon, Generation and PECO areunable to predict whether and to what extent they may experience additional claims in the future as a result of this ruling; as such noincrease to the asbestos-related bodily injury liability has been recorded as of December 31, 2013. Increased claims activity resulting fromthis ruling could have a material adverse impact on Exelon, Generation’s and PECO’s future results of operations and cash flows. BGE. Since 1993, BGE and certain Constellation (now Generation) subsidiaries have been involved in several actions concerningasbestos. The actions are based upon the theory of “premises liability,” alleging that BGE and Generation knew of and exposed individuals toan asbestos hazard. In addition to BGE and Generation, numerous other parties are defendants in these cases. Approximately 486 individuals who were never employees of BGE or certain Constellation subsidiaries have pending claims eachseeking several million dollars in compensatory and punitive damages. Cross-claims and third-party claims brought by other defendantsmay also be filed against BGE and certain Constellation subsidiaries in these actions. To date, most asbestos claims which have beenresolved have been dismissed or resolved without any payment by BGE or certain Constellation subsidiaries and a small minority of thesecases has been resolved for amounts that were not material to BGE or Generation’s financial results. Discovery begins in these cases after they are placed on the trial docket. At present, only two of the pending cases are set for trial. Giventhe limited discovery in these cases, BGE and Generation do not know the specific facts that are necessary to provide an estimate of thereasonably possible loss relating to these claims; as such, no accrual has been made and a range of loss is not estimable. The specific factsnot known include: • the identity of the facilities at which the plaintiffs allegedly worked as contractors; • the names of the plaintiffs’ employers; • the dates on which and the places where the exposure allegedly occurred; and • the facts and circumstances relating to the alleged exposure. Insurance and hold harmless agreements from contractors who employed the plaintiffs may cover a portion of any awards in theactions. Federal Energy Regulatory Commission Investigation (Exelon and Generation). On January 30, 2012, FERC published a notice on its website regarding a non-public investigation of certain of Constellation’s powertrading activities in and around the ISO-NY from September 2007 through December 2008. Prior to the merger, Constellation announced onMarch 9, 2012, that it had resolved the FERC investigation. Under the settlement, Constellation agreed to pay, and has paid, a $135 millioncivil penalty and $110 million in disgorgement. During the year ended December 31, 2012, Generation recorded expense of $195 million in operating and maintenance expense withthe remaining $50 million recorded as a Constellation pre-acquisition contingency.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) Continuous Power Interruption (ComEd) Section 16-125 of the Illinois Public Utilities Act provides that in the event an electric utility, such as ComEd, experiences a continuouspower interruption of four hours or more that affects (in ComEd’s case) more than 30,000 customers, the utility may be liable for actualdamages suffered by customers as a result of the interruption and may be responsible for reimbursement of local governmental emergencyand contingency expenses incurred in connection with the interruption. Recovery of consequential damages is barred. The affected utilitymay seek from the ICC a waiver of these liabilities when the utility can show that the cause of the interruption was unpreventable damagedue to weather events or conditions, customer tampering, or certain other causes enumerated in the law. On August 18, 2011, ComEd sought from the ICC a determination that ComEd is not liable for damage compensation to customers inconnection with the July 11, 2011 storm system that produced multiple power interruptions that in the aggregate affected more than 900,000customers in ComEd’s service territory, as well as for five other storm systems that affected ComEd’s customers during June and July 2011(Summer 2011 Storm Docket). In addition, on September 29, 2011, ComEd sought from the ICC a determination that it was not liable fordamage compensation related to the February 1, 2011 blizzard (February 2011 Blizzard Docket). On June 5, 2013, the ICC approved a complete waiver of liability for five of the six summer storms and the February 2011 blizzard.However, the ICC held that for the July 11, 2011 storm, 34,559 interruptions were preventable and therefore no waiver should apply. Asrequired by the ICC’s Order, ComEd notified relevant customers that they may be entitled to seek reimbursement of incurred costs inaccordance with a claims procedure established under ICC rules and regulations. In addition, the ICC found that ComEd did notsystematically fail in its duty to provide adequate, reliable and safe service. As a result, the ICC rejected the Illinois Attorney General’srequest for the ICC to open an investigation into ComEd’s infrastructure and storm hardening investments. Following the ICC’s June 26, 2013 denial of ComEd’s request for rehearing, on June 27, 2013 ComEd filed an appeal of both thesummer and winter storm dockets with the Illinois Appellate Court regarding the ICC’s interpretation of Section 16-125 of the Illinois PublicUtilities Act. ComEd cannot predict the outcome of appeals. As a result of the ICC’s June 5, 2013 ruling, ComEd established a liability, which was not material, for potential reimbursements foractual damages incurred by the 34,559 customers covered by the ICC’s June 5, 2013 Order. The liability recorded represents the low end ofa range of potential losses given that no amount within the range represents a better estimate. ComEd’s ultimate liability will be based onactual claims eligible for reimbursement as well as the outcome of the appeal. Although reimbursements for actual damages will differ fromthe estimated accrual recorded, at this time ComEd does not expect the difference to be material to ComEd’s results of operations or cashflows. ComEd has not recorded an accrual for reimbursement of local governmental emergency and contingency expenses as a range of loss,if any, cannot be reasonably estimated at this time, but may be material to ComEd’s results of operations and cash flows. Telephone Consumer Protection Act Lawsuit (ComEd) On November 19, 2013, a class action complaint was filed in Cook County on behalf of a single individual and a presumptive classthat would include all customers in ComEd’s service territory who 407Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) were enrolled by the Company in ComEd’s Outage Alert text message program. The complaint alleges that ComEd violated the TelephoneConsumer Protection Act (“TCPA”) by sending approximately 1.2 million text messages to customers without first obtaining their consent toreceive such messages. The complaint seeks certification of a class along with statutory damages, attorneys’ fees, and an order prohibitingComEd from sending additional text messages. Such statutory damages could range from $500 to $1,500 per text. However, ComEd ispreparing a motion to dismiss this class action complaint and will vigorously contest the allegations of this suit. The ultimate outcome of thisproceeding is uncertain, and an amount, if any, which might be asserted, cannot be reasonably estimated at this time, but may be materialto ComEd’s results of operations and cash flows. As a result, ComEd has not established a reserve for this complaint as of December 31,2013. Securities Class Action (Exelon) Three federal securities class action lawsuits were filed in the United States District Courts for the Southern District of New York andthe District of Maryland between September 2008 and November 2008 against Constellation. The cases were filed on behalf of a proposedclass of persons who acquired publicly traded securities, including the Series A Junior Subordinated Debentures (Debentures), ofConstellation between January 30, 2008 and September 16, 2008, and who acquired Debentures in an offering completed in June 2008.The securities class actions generally allege that Constellation, a number of its former officers or directors, and the underwriters violated thesecurities laws by issuing a false and misleading registration statement and prospectus in connection with Constellation’s June 27, 2008offering of the Debentures. The securities class actions also allege that Constellation issued false or misleading statements or was aware ofmaterial undisclosed information which contradicted public statements, including in connection with its announcements of financial resultsfor 2007, the fourth quarter of 2007, the first quarter of 2008 and the second quarter of 2008 and the filing of its first quarter 2008 Form 10-Q.The securities class actions sought, among other things, certification of the cases as class actions, compensatory damages, reasonable costsand expenses, including counsel fees, and rescission damages. The Southern District of New York granted the defendants’ motion to transfer the two securities class actions filed in Maryland to theDistrict of Maryland, and the actions have since been transferred for coordination with the securities class action filed there. On May 9, 2013,the federal court in Maryland preliminarily approved the settlement of Constellation’s 2008 Securities Class Action for a payment of $4million, which will be paid by Constellation’s insurer. Notice of the settlement was provided to class members in June 2013 and the courtapproved the final settlement on November 4, 2013. This settlement will resolve all of Constellation’s litigation arising from the 2008Securities Class Action lawsuit. Fund Transfer Restrictions (Exelon, Generation, ComEd, PECO and BGE) Under applicable law, Exelon may borrow or receive an extension of credit from its subsidiaries. Under the terms of Exelon’sintercompany money pool agreement, Exelon can lend to, but not borrow from the money pool. The Federal Power Act declares it to be unlawful for any officer or director of any public utility “to participate in the making or paying ofany dividends of such public utility from any funds properly included in capital account.” What constitutes “funds properly included in capitalaccount” is undefined in the Federal Power Act or the related regulations; however, FERC has consistently interpreted the provision to allowdividends to be paid as long as: (1) the source of the dividends is clearly disclosed; 408Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) (2) the dividend is not excessive; and (3) there is no self-dealing on the part of corporate officials. While these restrictions may limit theabsolute amount of dividends that a particular subsidiary may pay, Exelon does not believe these limitations are materially limiting because,under these limitations, the subsidiaries are allowed to pay dividends sufficient to meet Exelon’s actual cash needs. Under Illinois law, ComEd may not pay any dividend on its stock unless, among other things, “[its] earnings and earned surplus aresufficient to declare and pay same after provision is made for reasonable and proper reserves,” or unless it has specific authorization from theICC. ComEd has also agreed in connection with financings arranged through ComEd Financing III that it will not declare dividends on anyshares of its capital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debt securitiesissued to ComEd Financing III; (2) it defaults on its guarantee of the payment of distributions on the preferred trust securities of ComEdFinancing III; or (3) an event of default occurs under the Indenture under which the subordinated debt securities are issued. PECO’s Articles of Incorporation prohibit payment of any dividend on, or other distribution to the holders of, common stock if, aftergiving effect thereto, the capital of PECO represented by its common stock together with its retained earnings is, in the aggregate, less thanthe involuntary liquidating value of its then outstanding preferred securities. On May 1, 2013, PECO redeemed all outstanding preferredsecurities. As a result, the above ratio calculation is no longer applicable. Additionally, PECO may not declare dividends on any shares of itscapital stock in the event that: (1) it exercises its right to extend the interest payment periods on the subordinated debentures, which wereissued 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 ofPEC L.P. or the preferred trust securities of PECO Trust IV; or (3) an event of default occurs under the Indenture under which thesubordinated debentures are issued. BGE pays dividends on its common stock after its board of directors declares them. However, BGE is subject to certain dividendrestrictions established by the MDPSC. First, BGE is prohibited from paying a dividend on its common shares through the end of2014. Second, BGE is prohibited from paying a dividend on its common shares if (a) after the dividend payment, BGE’s equity ratio wouldbe below 48% as calculated pursuant to the MDPSC’s ratemaking precedents or (b) BGE’s senior unsecured credit rating is rated by two ofthe three major credit rating agencies below investment grade. Finally, BGE must notify the MDPSC that it intends to declare a dividend onits common shares at least 30 days before such a dividend is paid. There are no other limitations on BGE paying common stock dividendsunless: (1) BGE elects to defer interest payments on the 6.20% Deferrable Interest Subordinated Debentures due 2043, and any deferredinterest remains unpaid; or (2) any dividends (and any redemption payments) due on BGE’s preference stock have not been paid. Baltimore City Franchise Taxes (BGE) The City of Baltimore claims that BGE has maintained electric facilities in the City’s public right-of-ways for over one hundred yearswithout the proper franchise rights from the City. BGE is currently reviewing the merits of this claim. BGE has not recorded an accrual forpayment of franchise fees for past periods as a range of loss, if any, cannot be reasonably estimated at this time. Franchise fees assessed infuture periods may be material to BGE’s results of operations and cash flows. 409Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

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 a reasonable possibility, and whether the loss or a range of loss is estimable, often involvesa series of complex judgments about future events. The Registrants maintain accruals for such losses that are probable of being incurred andsubject to reasonable estimation. Management is sometimes unable to estimate an amount or range of reasonably possible loss, particularlywhere (1) the damages sought are indeterminate, (2) the proceedings are in the early stages, or (3) the matters involve novel or unsettledlegal theories. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including apossible eventual loss.

Segment Information (Exelon, Generation, ComEd, PECO and BGE) Operating segments for each of the Registrants are determined based on information used by the chief operating decision maker(s)(CODM) in deciding how to evaluate performance and allocate resources at each of the Registrants. Exelon has nine reportable segments, ComEd, PECO, BGE and Generation’s six power marketing reportable segments consisting ofthe Mid-Atlantic, Midwest, New England, New York, ERCOT and all other regions not considered individually significant referred tocollectively as “Other Regions”; including the South, West and Canada. Generation’s expanded number of reportable segments is the resultof the acquisition of Constellation on March 12, 2012. ComEd, PECO and BGE each represent a single reportable segment; as such, noseparate segment information is provided for these Registrants. Exelon evaluates the performance of ComEd, PECO and BGE based on netincome. The CODMs for ComEd, PECO, and BGE evaluate performance and allocate resources for their respective companies based on netincome and return on equity for ComEd, PECO, and BGE each as single integrated businesses. 418 (a)(b)(b) (a)(b)(b)Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Combined Notes to Consolidated Financial Statements—(Continued)(Dollars in millions, except per share data unless otherwise noted) The foundation of Generation’s six reportable segments is based on the geographic location of its assets, and is largely representative ofthe footprints of an ISO / RTO and/or NERC region. Descriptions of each of Generation’s six reportable segments are as follows: • Mid-Atlantic represents operations in the eastern half of PJM, which includes Pennsylvania, New Jersey, Maryland, Virginia, WestVirginia, Delaware, the District of Columbia and parts of North Carolina. • Midwest represents operations in the western half of PJM, which includes portions of Illinois, Indiana, Ohio, Michigan, Kentuckyand Tennessee, and the United States footprint of MISO excluding MISO’s Southern Region, which covers all or most of NorthDakota, South Dakota, Nebraska, Minnesota, Iowa, Wisconsin, the remaining parts of Illinois, Indiana, Michigan and Ohio notcovered by PJM, and parts of Montana, Missouri and Kentucky. • New England represents the operations within ISO-NE covering the states of Connecticut, Maine, Massachusetts, NewHampshire, Rhode Island and Vermont. • New York represents operations within ISO-NY, which covers the state of New York in its entirety. • ERCOT represents operations within Electric Reliability Council of Texas, covering most of the state of Texas. • Other Regions not considered individually significant: • South represents operations in the FRCC, MISO’s Southern Region, and the remaining portions of the SERC not includedwithin MISO or PJM, which includes all or most of Florida, Arkansas, Louisiana, Mississippi, Alabama, Georgia,Tennessee, North Carolina, South Carolina and parts of Missouri, Kentucky and Texas. Generation’s South region alsoincludes operations in the SPP, covering Kansas, Oklahoma, most of Nebraska and parts of New Mexico, Texas, Louisiana,Missouri, Mississippi and Arkansas. • West represents operations in the WECC, which includes California ISO, and covers the states of California, Oregon,Washington, Arizona, Nevada, Utah, Idaho, Colorado, and parts of New Mexico, Wyoming and South Dakota. • Canada represents operations across the entire country of Canada and includes the AESO, OIESO and the Canadian portionof MISO. The CODMs for Exelon and Generation evaluate the performance of Generation’s power marketing activities and allocate resourcesbased on revenue net of purchased power and fuel expense. Generation believes that revenue net of purchased power and fuel expense is auseful measurement of operational performance. Revenue net of purchased power and fuel expense is not a presentation defined underGAAP and may not be comparable to other companies’ presentations or deemed more useful than the GAAP information providedelsewhere in this report. Generation’s operating revenues include all sales to third parties and affiliated sales to ComEd, PECO and BGE.Purchased power costs include all costs associated with the procurement and supply of electricity including capacity, energy and ancillaryservices. Fuel expense includes the fuel costs for Generation’s own generation and fuel costs associated with tolling agreements.Generation’s other business activities, including retail and wholesale gas, upstream natural gas, proprietary trading, energy efficiency anddemand response, heating, cooling, and cogeneration facilities, and home improvements, sales of electric and gas appliances, servicing ofheating, air conditioning, plumbing, electrical, and indoor quality systems, and investments in energy-related proprietary technology are notallocated to regions.

ITEM 9A.CONTROLS AND PROCEDURES Exelon, Generation, ComEd, PECO and BGE—Disclosure Controls and Procedures During the fourth quarter of 2013, 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 andreporting of information in that registrant’s periodic reports that it files with the SEC. These disclosure controls and procedures have beendesigned by each registrant to ensure that (a) information relating to that registrant, including its consolidated subsidiaries, that is required tobe 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 appropriateto 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 allmisstatements may be detected. These inherent limitations include the realities that judgments in decision-making can be faulty and thatbreakdowns can occur because of simple error or mistake. Additionally, controls could be circumvented by the individual acts of somepersons or by collusion of two or more people. Accordingly, as of December 31, 2013, the principal executive officer and principal financial officer of each registrant concluded that suchregistrant’s disclosure controls and procedures were effective to accomplish their objectives. Exelon, Generation, ComEd, PECO and BGE—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 andto maintain dynamic systems that change as conditions warrant. However, there have been no changes in internal control over financialreporting that occurred during the fourth quarter of 2013 that have materially affected, or are reasonably likely to materially affect, any ofExelon’s, Generation’s, ComEd’s, PECO’s and BGE’s internal control over financial reporting. Exelon, Generation, ComEd, PECO and BGE—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 31,2013. As a result of that assessment, management determined that there were no material weaknesses as of December 31, 2013 and,therefore, concluded that each registrant’s internal control over financial reporting was effective. Management’s Report on Internal ControlOver Financial Reporting is included in ITEM 8.

The Administrator shall cause to be made such periodic computations as it shall deemnecessary or appropriate to determine whether either of the tests set forth in paragraph (b)(1) or (b)(2) of this Section 4.4 shall be satisfied during a Plan Year,and, if it appears to the Administrator that neither of such tests will be satisfied, the Administrator shall take such steps as it deems necessary or appropriateto adjust the Employer Matching Contributions made, After-Tax Contributions made, and any Before-Tax Contributions treated as Employer MatchingContributions pursuant to paragraph (d)(2) of this Section 4.4 for all or a portion of such Plan Year on behalf of Participants who are highly compensatedeligible employees to the extent necessary in order for one of such tests to be satisfied. If after the end of a Plan Year it is determined that regardless of any stepstaken neither of the tests set forth in paragraph (b)(1) or (b)(2) of this Section 4.4 shall be satisfied with respect to such Plan Year, the Administrator shallcalculate the total amount by which any such contributions on behalf of Participants who are highly compensated eligible employees must be reduced in orderto satisfy either such test, in the manner prescribed by section 401(m)(6) of the Code (the “excess aggregate contributions amount”). The amount to be reducedwith respect to Participants who are highly compensated eligible employees shall be determined by first reducing the After-Tax Contributions (including Before-Tax Contributions recharacterized as After-Tax Contributions pursuant to paragraph (e)(1) of this Section 4.4) and then by reducing the Employer MatchingContributions for each Participant whose actual dollar amount of such aggregate contributions for such Plan Year is highest until such reduced dollar amountequals the next highest dollar amount of such contributions for such Plan Year on behalf of any other highly compensated eligible employee, or until the totalreduction equals the excess aggregate contributions amount.

If the reductions required by this subparagraph exceed the amount of After-Tax Contributions made or tobe made by any Participant for such Plan Year and the amount of Employer Matching Contributions made or to be made on behalf of such Participant forsuch Plan Year, any Before-Tax Contributions made on behalf of such Participant that the Administrator has elected to treat as Employer MatchingContributions pursuant to paragraph (d)(2) of this Section 4.4 shall also be adjusted and taken into account in accordance with this subparagraph, except thatsuch Before-Tax Contributions may not be recharacterized as After-Tax Contributions. 29Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Limitation on Employer Contributions.The contributions of an Employer for any Plan Year shall not exceed the maximum amount for which a deduction is allowable to such Employer forfederal income tax purposes for the fiscal year of such Employer that coincides with such Plan Year.Any contribution made by an Employer by reason of a good faith mistake of fact, or the portion of any contribution made by an Employer that exceedsthe maximum amount for which a deduction is allowable to such Employer for federal income tax purposes by reason of a good faith mistake in determiningthe maximum allowable deduction, shall upon the request of such Employer be returned by the Trustee to the Employer. An Employer’s request and the returnof any such contribution must be made within one year after such contribution was mistakenly made or after the deduction of such excess portion of suchcontribution was disallowed, as the case may be. The amount to be returned to an Employer pursuant to this paragraph shall be the excess of (i) the amountcontributed over (ii) the amount that would have been contributed had there not been a mistake of fact or a mistake in determining the maximum allowablededuction. Earnings attributable to the mistaken contribution shall not be returned to the Employer, but losses attributable thereto shall reduce the amount to beso returned. If the return to the Employer of the amount attributable to the mistaken contribution would cause the balance of any Participant’s account as of thedate such amount is to be returned (determined as if such date coincided with the close of a Plan Year) to be reduced to less than what would have been thebalance of such account as of such date had the mistaken amount not been contributed, the amount to be returned to the Employer shall be limited so as toavoid such reduction.Any Before-Tax Contributions returned to an Employer pursuant to this Section 4.5 shall be treated as the return of Untaxed Contributions, up to theextent Untaxed Contributions were made by such Participant to the Plan for such Plan Year and, to the extent that the returned contributions exceed suchUntaxed Contributions, such returned contributions shall be treated as Designated Roth Contributions made by the Participant to the Plan for the Plan Year. 30Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

An Employee who satisfies the eligibility requirements of Section 2.1 can elect tobecome a Participant by submitting an Appropriate Request with the Plan Administrator. In making the Appropriate Request, the Employee must (i) designatethe rate of contribution under the After-Tax and/or Before-Tax Options; (ii) indicate the Investment Funds to which contributions under the After-Tax and/orBefore-Tax Options will be allocated and the percentage allocated to each Investment Fund; and (iii) agree to be bound by the terms and conditions of the Plan,a copy of which will be furnished to the Employee upon request. 5Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. After-Tax Option contributions, which are taxed to the Participant when contributed to the Plan, are treated as direct contributions to the Plan by theParticipant. Therefore, an Appropriate Request submitted with respect to the After-Tax Option authorizes the Company to deduct a stated percentage of theParticipant’s Eligible Compensation from his pay and transmit the amount deducted to the Plan to be invested.Before-Tax Option contributions, which are not taxed to the Participant (for federal income tax purposes) until distributed from the Plan, are treated asreductions in the salary of the Participant which are then contributed to the Plan by the Company on behalf of the Participant. Therefore, pursuant to anAppropriate Request submitted with respect to the Before-Tax Option, the Participant undertakes to forego the receipt of a stated percentage of EligibleCompensation. In return, the Company will contribute to the Plan an amount equal to the deferral.An eligible Employee who does not elect to become a Participant in the After-Tax and/or Before-Tax Options at the earliest possible eligibility date asprovided in Section 2.1, may elect to become a Participant at a later date by submitting an Appropriate Request with the Plan Administrator.

The Participant must also agree to be bound by the terms and conditions of the Plan, a copy ofwhich will be furnished to the Employee upon request. 2.2(c)Employee Stock AccountAn Employee or former Employee for whom a balance in an Employee Stock Account has been established under the Plan is automatically a Participant.Participation in the Plan through the establishment of an Employee Stock Account does not affect an Employee’s eligibility for or participation in the After-Taxand Before-Tax Options or the rollover provision. 7Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

APPENDIX BCODE LIMITATIONS ON CONTRIBUTIONS TO THE PLANB-1 Dollar Limitation on Participants’ Before-Tax Option Contributions – During any Plan Year, a Participant’s contributions under the Before-TaxOption of the Plan, when combined with his elective deferrals within the meaning of Code Section 402(g)(3) under all other plans of the Employer and anyother employer during the Plan Year, may not exceed the limitation of Code Section 402(g) (e.g., $13,000 in 2004). This dollar limitation will be adjustedannually at the same time and in the same manner as provided under Code Section 402(g)(5). To prevent the limitation from being exceeded in any Plan Year,the Plan Administrator may prospectively limit the rate of contribution which a Participant may elect to contribute under the Before-Tax Option. Participantswhose Before-Tax Option contributions are limited by this Section B-1 are automatically treated as electing to increase their contributions under the After-TaxOption by an amount equal to the Participant’s Before-Tax Option contribution percentage in excess of the limitation.If due to an administrative error a Participant’s contributions under the Before-Tax Option exceed the limitation of Code Section 402(g) as of the close ofany Plan Year, the Participant will receive a distribution from the Plan of the amount constituting such excess Before-Tax Option contributions and any incomeor loss allocable thereto by no later than April 15th following the close of the Plan Year to which such excess deferrals relate.If during the Plan Year in which such excess Before-Tax Option contributions occurred, or prior to March 1st following the close of such Plan Year, aParticipant submits a written certification to the Plan Administrator stating that all or a portion of the Participant’s contributions to the Plan under the Before-Tax Option constitute excess 90Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

For the purposes of clarity, the incomeor loss allocable to excess deferrals will not be calculated for the period after the close of the Plan Year in which the excess deferral occurred and prior to thedistribution (i.e. the ‘gap period’).For purposes of computing the Section B-2 limitations under Code Section 415(c), excess deferrals under Code Section 402(g) will be treated ascontributions under the Before-Tax Option, unless a distribution of such excess deferrals and any income or loss allocable thereto is made no later thanApril 15th following the close of the Plan Year to which such excess deferrals relate. Excess deferrals under Code Section 402(g) will be treated as contributionsunder the Before-Tax Option for purposes of computing the Code Section 401(k) limitations as provided in Section B-4.1, but only for contributions on behalfof Highly Compensated Employees, even if such excess deferrals and any income or loss allocable thereto is distributed by April 15th following the close ofthe Plan Year to which such excess deferrals relate.

B-2.2 Elimination of Excess Annual Additions — To the extent necessary to prevent the limitation of this Section B-2 from being exceeded in anylimitation year, the Plan Administrator may prospectively reduce contributions under the Plan during such limitation year. A Participant’s prospectiveSupplemental Contributions under the After-Tax Option will be reduced first, followed in order by Supplemental Contributions under the Before-Tax Option,Basic Contributions under the After-Tax Option, and Basic Contributions under the Before-Tax Option until such reductions eliminate any excess annualadditions.B-2.3 Limitation Year — For purposes of applying the limitations of Code Section 415 to the Plan, the “limitation year” shall be the calendar year.If the Employer maintains multiple defined contribution plans that are aggregated with the Plan for purposes of Code Section 415 pursuant to AppendixB-2.4 and that have different limitation years, the rules of Code Section 415(c) will be applied to the limitation year of the Plan, and are to be applied withrespect to each limitation year of each other such plan. For each limitation year of the Plan, the requirements of Code Section 415 are applied to annualadditions that are made for that time period with respect to the Participant under all such aggregated plans.B-2.4 Aggregated Plans — The sum of the annual additions credited to a Participant’s account in any limitation year for all of the qualified definedcontribution plans of the Employer or a predecessor employer (as such term in used in Code Section 415(f) and the regulations thereunder), regardless ofwhether a plan is terminated, may not exceed the limitations of Code Section 415(c). 93Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Additionally, the actual deferral percentage for thegroup of Highly Compensated Employees who are eligible to participate under the Before-Tax Option for the Plan Year shall not exceed the actualdeferral percentage for the group of Nonhighly Compensated Employees who are eligible to participate under the Before-Tax Option for the PlanYear, multiplied by two (2). 94Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

In determining whether the Plan satisfies the limitation under this Section B-4, all Before-Tax Option contributions and other electivedeferrals, that are made to the Plan and any other plans of the Employer that are aggregated with the Plan for purposes of Code Section 401(a)(4)and 410(b) (other than Code Section 410(b)(2)(A)(ii)), are to be treated as made under a single plan. If the Plan and any other plans of theEmployer are permissively aggregated for purposes of satisfying this limitation under Section B-4, the aggregated plans must also satisfy CodeSections 401(a)(4) and 410(b) as though they were a single plan.For the purposes of this Section “actual deferral percentage” means, with respect to the group of Highly Compensated Employees who areeligible to participate under the Before-Tax Option and the group of Nonhighly Compensated Employees who are eligible to participate under theBefore-Tax Option for the Plan Year, the average of the actual deferral ratios, calculated separately for each Employee who is eligible to participateunder the Before-Tax Option for the Plan Year in each group.The “actual deferral ratio” for each such Employee is equal to the annual Participant contributions under the Before-Tax Option and any“Qualified Nonelective Contribution” made on behalf of such Participant divided by the Participant’s Compensation. For purposes of thisSection, Compensation generally means an Employee’s total Compensation for the Plan Year; however, Compensation does not include amountsrelated to any portion of the Plan Year in which an Employee was not eligible to 95Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

The actual deferral ratio of a Highly Compensated Employee is determined by treating all plans ofthe Employer that are subject to Code Section 401(k) under which the Highly Compensated Employee is eligible to participate (other than thosethat may not be permissively aggregated) as a single plan.The actual deferral ratio for each Employee who is eligible to participate under the Before-Tax Option and the actual deferral percentage forthe Highly Compensated Employee group and the Nonhighly Compensated Employee group shall be calculated to the nearest one-hundredth of onepercent.B-4.2 Elimination of Excess Contributions – To prevent the limitation under this Section B-4 from being exceeded in any Plan Year, the PlanAdministrator may prospectively limit the rate of contribution which a Highly Compensated Employee may elect to contribute under the Before-Tax Option.The Plan Administrator will establish a maximum rate of contribution for Highly Compensated Employees to avoid exceeding the limits of this SectionB-4.The maximum rate of contribution for Highly Compensated Employees will be determined by first reducing by 1/10 of a percent the rate of contributionunder the Before-Tax Option of the Highly Compensated Employees having the highest actual deferral ratio. The rate of contribution will be reduced until theADP test is satisfied, or until the actual deferral ratio is reduced to the point where it equals the ratio of the Highly Compensated Employee with the next highestactual deferral ratio. This “leveling” process will be repeated until the ADP test is satisfied.Highly Compensated Employee Participants whose Before-Tax Option contributions are prospectively limited by this Section B-4 are automaticallytreated as electing to increase their contributions under the After-Tax Option by an amount equal to the Participant’s Before-Tax Option contribution percentagein excess of the limitation. 96Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. If, after the end of the Plan Year, it is determined that the limitation of this Section B-4 has been exceeded, the Plan Administrator may authorize theTrustee to distribute the excess contributions and the income or loss allocable thereto to the Highly Compensated Employees with the highest dollar deferralamounts. Excess contributions are determined by first determining how much the actual deferral ratio of the Highly Compensated Employee with the highestactual deferral ratio would have to be reduced to satisfy the ADP test or cause such ratio to equal the actual deferral ratio of the Highly Compensated Employeewith the next highest ratio. Second, this process is repeated until the ADP test would be satisfied. The amount of excess contributions is equal to the sum ofthese hypothetical reductions multiplied by the Highly Compensated Employee’s Compensation. Excess contributions shall be distributed or recharacterized ascontributions under the After-Tax Option (each as set forth below), starting with the Highly Compensated Employee with the greatest dollar amount ofcontributions under the Before-Tax Option during the Plan Year until the amount of excess contributions has been accounted for. At the discretion of the PlanAdministrator, the excess contributions may be distributed on or before March 15th following the end of the Plan Year for which the limitation of this SectionB-4 is exceeded. With respect to the distribution of excess contributions, such distribution may be postponed, but not later than the close of the Plan Yearfollowing the Plan Year to which the contributions are allocable. To the extent any Company Matching Contributions were allocable to the Participant’s accountas a result of excess contributions, such Company Matching Contributions and income or loss allocable thereto will be forfeited and thereafter applied toreduce Company contributions to the Plan. 97Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Income allocable toexcess contributions shall be determined on a date that is no more than 7 days before such contributions are distributed.In the event a distribution of excess contributions occurs, the Company will designate that the distribution is comprised of excess contributions andincome or loss allocable thereto.As an alternative to the distribution of amounts exceeding the limitation of this Section B-4.2 after the end of the Plan Year, the Plan Administrator maycause the excess contributions to be recharacterized first as “catch-up contributions” in accordance with, and subject to the limitations of, Section 414(v) of theCode to the extent that the Participant would otherwise be eligible to make such catch-up contributions under Section 3.1(a) of the Plan, and then ascontributions under the After-Tax Option. The option to recharacterize excess contributions is provided at the sole discretion of the Plan Administrator.The limitation set forth in this Section B-4 will be determined and the computation of any distribution or recharacterization of contributions requiredunder this Section B-4.2 will be made after adjustments are made to contributions under the Before-Tax Option as necessary to avoid exceeding the CodeSection 402(g) dollar limitations on contributions as provided in Section B-1. 98Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

As of the date of any adjustment in the limitations prescribed by CodeSection 401(k), the provisions of this Section B-4 will be deemed to have been amended to reflect such adjustment.B-5 Limitation on Participant Contributions Under the After-Tax Option and Company Matching Contributions (ACP Test)B-5.1 Maximum Annual Contribution – For each Plan Year, the actual contribution percentage (ACP) for the group of Highly Compensated Employeeswho are eligible to participate through Payroll Deduction for the Plan Year shall not exceed the greater of: (1)125 percent of the actual contribution percentage for the group of Nonhighly Compensated Employees who are eligible to participate throughPayroll Deduction for the Plan Year; or (2)the lesser of (a) 200 percent of the actual contribution percentage for the group of Nonhighly Compensated Employees who are eligible to participatethrough Payroll Deduction for the Plan Year, or (b) the actual contribution percentage for the group of Nonhighly Compensated Employees who areeligible to participate through Payroll Deduction for the Plan Year plus two (2) percentage points.In determining whether the Plan satisfies the limitation under this Section B-5, all employee and matching contributions that are made to the Plan andany other plans of the Employer that are aggregated with the Plan for purposes of Code Sections 401(a)(4) and 410(b) (other than CodeSection 410(b)(2)(A)(ii)), are to be treated as made under a single plan.

Past financial performance is no guarantee of future results. For purposes of this Section, “actual contribution percentage” for a Plan Year means, with respect to the group of Highly Compensated Employees whoare eligible to participate through the After-Tax and/or Before-Tax Options and the group of Nonhighly Compensated Employees who are eligible to participatethrough the After-Tax and/or Before-Tax Options for the Plan Year, the average of the actual contribution ratios, calculated separately for each Employee who iseligible to participate through the After-Tax and/or Before-Tax Options for the Plan Year in each group.The “actual contribution ratio” for each such Employee is equal to the sum of their annual Participant contributions under the After-Tax Option and theCompany Matching Contributions allocated to their accounts, divided by the Participant’s Compensation. For purposes of this Section, Compensationgenerally means an Employee’s total Compensation for the Plan Year; however, Compensation does not include amounts related to any portion of the Plan Yearin which an Employee was not eligible to participate under the After-Tax Option of the Plan or to have Company Matching Contributions allocated to hisaccount. The actual contribution ratio of a Highly Compensated Employee is determined by treating all plans of the Employer that are subject to CodeSection 401(m) under which the Highly Compensated Employee is eligible to participate (other than those that may not be permissively aggregated) as a singleplan.The actual contribution ratio for each Employee who is eligible to participate through the After-Tax and/or Before-Tax Options and the actual contributionpercentage for the Highly Compensated Employee group and the Nonhighly Compensated Employee group shall be calculated to the nearest one-hundredth ofone percent. 100Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. To the extent provided by Treasury regulations, the Plan Administrator may elect to apply the limitation under this Section by including Employeeelective deferrals under the Before-Tax Option.B-5.2 Elimination of Excess Contributions – To prevent the limitation under this Section B-5 from being exceeded in any Plan Year, the PlanAdministrator may prospectively limit the rate of contribution which a Highly Compensated Employee may elect to contribute under the After-Tax Option and,if necessary, may reduce amounts which would otherwise be contributed for a Highly Compensated Employee as a Company Matching Contribution.The Plan Administrator will establish a maximum rate of contribution for Highly Compensated Employees to avoid exceeding the limits of this SectionB-5.The maximum rate of contribution for Highly Compensated Employees will be determined by first reducing by 1/10 of a percent the rate of contributionunder the After-Tax Option, and any related Company Matching Contribution, of the Highly Compensated Employees having the highest actual contributionratio. The rate of contribution will be reduced until the ACP test is satisfied, or until the actual contribution ratio is reduced to the point where it equals the ratioof the Highly Compensated Employee with the next highest actual contribution ratio. This “leveling” process will be repeated until the ACP test is satisfied.Any After-Tax Option contributions resulting from the recharacterization of Before-Tax Option contributions under the provisions of Section B-4.2 areincluded in the computation of the actual contribution percentage and are subject to limitation under this Section B-5. If the After-Tax Option contributions ofthe Highly Compensated Employee with the highest average contribution ratio have been reduced to zero, and further reduction is necessary to avoid exceedingthe limitation, then Company Matching Contributions relating to Before-Tax Option contributions will be reduced also. 101Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.

Past financial performance is no guarantee of future results. Highly Compensated Employees whose After-Tax Option contributions are limited by this Section B-5, may elect to either prospectively increase theircontributions under the Before-Tax Option or increase their cash compensation by an amount equal to the percentage of Eligible Compensation in excess of thelimitation. If the Participant fails to make an election regarding such excess, the excess will be paid to the Participant as cash compensation. Anyrecharacterization elected by the Participant will be permitted only if it does not cause any other limitations described in Appendix B to be exceeded.If, after the end of the Plan Year, it is determined that the limitation of this Section B-5 has been exceeded, the Plan Administrator may authorize theTrustee to distribute the excess aggregate contributions and income or loss allocable thereto to the Highly Compensated Employees with the highest dollarcontribution amounts. Excess contributions are determined by first determining how much the actual contribution ratio of the Highly Compensated Employeewith the highest actual contribution ratio would have to be reduced to satisfy the ACP test or cause such ratio to equal the actual contribution ratio of the HighlyCompensated Employee with the next highest ratio. Second, this process is repeated until the ACP test would be satisfied. The amount of excess contributionsis equal to the sum of these hypothetical reductions multiplied by the Highly Compensated Employee’s Compensation. Excess contributions shall bedistributed as set forth below, starting with the Highly Compensated Employee with the greatest dollar amount of contributions under the After-Tax Optionduring the Plan Year until the amount of excess contributions has been accounted for. At the discretion of the Plan Administrator, the excess aggregatecontributions may be distributed on or before March 15th following the end of the Plan Year for which the limitation of this Section B-5 was exceeded. Withrespect to the distribution of excess aggregate contributions, such distribution may be postponed, but not later than the close of the Plan Year following the PlanYear to which the contributions are allocable. 102Source: BALTIMORE GAS & ELECTRIC CO, 10-K, February 14, 2014Powered by Morningstar® Document Research℠The information contained herein may not be copied, adapted or distributed and is not warranted to be accurate, complete or timely.
