NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Basis of Presentation

This Quarterly Report on Form 10-Q is a combined report of Constellation Energy Group, Inc. (Constellation Energy) and Baltimore Gas and Electric Company (BGE). References in this report to "we" and "our" are to Constellation Energy and its subsidiaries, collectively. References in this report to the "regulated business(es)" are to BGE.

Various factors can have a significant impact on our results for interim periods. This means that the results for this quarter are not necessarily indicative of future quarters or full year results given the seasonality of our business.

        Our interim financial statements on the previous pages reflect all adjustments that management believes are necessary for the fair statement of the results of operations for the interim periods presented. These adjustments are of a normal recurring nature.

        We have evaluated events or transactions that occurred after JuneSeptember 30, 2009 for inclusion in these financial statements through August 7,November 6, 2009, the date these financial statements were issued.

Reclassifications

We have reclassified certain prior-period amounts:

        We discuss our adoption of SFAS No. 160 in more detail on page 41.

        We also made the following reclassifications:

Investment Agreement with EDF Group

On December 17, 2008, we entered into an Investment Agreement with EDF Group and related entities (EDF) under which EDF will purchase from us a 49.99% membership interest in our nuclear generation and operation business for $4.5 billion (subject to certain adjustments). We discuss the Investment Agreement with EDF in more detail inNote 15 of our 2008 Annual Report on Form 10-K.

        In October 2009, the Maryland PSC issued an order approving our transaction with EDF subject to the following conditions:

        With the receipt of the Maryland PSC's order, Constellation Energy and EDF are proceeding with closing this transaction. Upon closing of the transaction, we will

sell a 49.99% membership interest in Constellation Energy Nuclear Group LLC and its affiliates (CENG), our nuclear generation and operation business, to EDF for total consideration of approximately $4.7 billion (includes $4.5 billion at close and expense reimbursements). As a result, we will cease to have a controlling financial interest in CENG and will deconsolidate CENG in the fourth quarter of 2009. The following summarizes the estimated impact of this transaction upon closing:

  
 
 (In billions)
 

Fair value of the consideration received from EDF

Estimated fair value of our retained interest in CENG

  4.7 

Carrying amount of CENG's assets and liabilities prior to deconsolidation

  (2.6)
  

Estimated pre-tax gain

 $6.8 
  

        Upon closing, we will account for our retained investment in CENG using the equity method and report our share of its earnings in the merchant energy segment. As a result, we will no longer record the individual income statement line items, but instead will record our share of the investment's earnings in a single line in our Consolidated Statements of Income (Loss).

        Immediately prior to the closing of the sale, we will execute a power purchase agreement (PPA) with CENG with a fair value of approximately $0.7 billion. We will report the PPA on our Consolidated Balance Sheets within "Unamortized energy contract assets" and amortize its value on our Consolidated Statements of Income (Loss) to "Fuel and purchased energy expense" over a period of approximately two years.

        In addition, the completion of the transaction with EDF will impact our credit facilities as discussed in theFinancing section beginning on page 21.

Merger Termination and Strategic Alternatives Costs

We incurred costs during the quarter ended September 30, 2009 primarily related to the transactions related to EDF, and sixother strategic alternatives costs. For the nine months ended JuneSeptember 30, 2009, we incurred costs related to the terminated merger agreement with MidAmerican Energy Holdings Company (MidAmerican), the conversion of our Series A Preferred Stock, the transactions related to EDF, and other strategic alternatives costs. These costs totaled $4.0$4.9 million pre-tax and $46.3$51.2 million pre-tax for the quarter and sixnine months ended JuneSeptember 30, 2009, respectively, and primarily relate to the first quarter of 2009 write-off of the unamortized debt discount associated with the 14% Senior Notes (Senior Notes) that were repaid in full to MidAmerican in January 2009.

Variable Interest Entities

As of JuneSeptember 30, 2009, we consolidated three variable interest entities (VIE) in which we were the primary beneficiary, and we had significant interests in sevensix VIEs for which we did not have controlling financial interests and, accordingly, were not the primary beneficiary. We discuss our VIEs in more detail inNote 4 of our 2008 Annual Report on Form 10-K.

Consolidated Variable Interest Entities

In 2007, BGE formed RSB BondCo LLC (BondCo), a special purpose bankruptcy-remote limited liability company, to acquire and hold rate stabilization property and to issue and service bonds secured by the rate stabilization property. In June 2007, BondCo purchased rate stabilization property from BGE, including the right to


Table of Contents

assess, collect, and receive non-bypassable rate stabilization charges payable by all residential electric customers of BGE. These charges are being assessed in order to recover previously incurred power purchase costs that BGE deferred pursuant to Senate Bill 1. We discuss Senate Bill 1 in more detail inManagement's Discussion and Analysis section of our 2008 Annual Report on Form 10-K.

        BGE determined that BondCo is a VIE for which it is the primary beneficiary. As a result, BGE, and we, consolidated BondCo.

        The BondCo assets are restricted and can only be used to settle the obligations of BondCo. Further, BGE is required to remit all payments it receives from customers for rate stabilization charges to BondCo. During the quarter and sixnine months ended JuneSeptember 30, 2009, BGE remitted $17.6$23.0 million and $42.1$65.1 million, respectively, to BondCo.

        BGE did not provide any additional financial support to BondCo during the quarter and sixnine months ended June


Table of Contents

September 30, 2009. Further, BGE does not have any contractual commitments or obligations to provide additional financial support to BondCo unless additional rate stabilization bonds are issued. The BondCo creditors do not have any recourse to the general credit of BGE in the event the rate stabilization charges are not sufficient to cover the bond principal and interest payments of BondCo.

        During the second quarter of 2009, our retail gas customer supply operation formed two new entities and combined them with our existing retail gas customer supply operation into a retail gas entity group for the purpose of entering into a collateralized gas supply agreement (GSA) with a third party gas supplier. While we own 100% of these entities, we determined that the retail gas entity group is a VIE because we providethere is not sufficient equity to fund the group's activities without the additional credit support to the gas supplierwe provide in the form of a letter of credit and a parental guarantee. We are the primary beneficiary of the retail gas entity group; accordingly, we consolidate the retail gas entity group as a VIE, including the existing retail gas customer supply operation, which we formerly consolidated as a voting interest entity.

        The gas supply arrangement is collateralized as follows:

        Other than credit support provided by the parental guarantee and the letter of credit, we do not have any contractual or other obligations to provide additional financial support to the retail gas entity group. The retail gas entity group creditors do not have any recourse to our general credit. Finally, we did not provide any financial support to the retail gas entity group during the quarter and nine months ended JuneSeptember 30, 2009, other than the initial equity contribution,contributions, parental guarantee and the letter of credit.

        The carrying amounts and classification of the above consolidated VIEs' assets and liabilities included in our consolidated financial statements at June 30, 2009 are as follows:

        All of the assets in the table above are restricted for settlement of the VIE obligations and all of the liabilities in the table above can only be settled using VIE resources.

        We also consolidate a retail power supply VIE for which we became the primary beneficiary in 2008 as a result of a modification to its contractual arrangements that changed the allocation of the economic risks and rewards of the VIE among the variable interest holders. The consolidation of this VIE did not have a material impact on our financial results or financial condition.

Unconsolidated Variable Interest Entities

As of JuneSeptember 30, 2009, we had significant interests in sevensix VIEs for which we were not the primary beneficiary. We have not provided any material financial or other support to these entities during the quarter and sixnine months ended JuneSeptember 30, 2009.

        Our maximum exposure to loss is the loss that we would incur in the unlikely event that our interests in all of these entities were to become worthless and we were required to fund the full amount of all guarantees associated with these entities. Our maximum exposure to loss as of JuneSeptember 30, 2009 consists of the following:

        We assess the risk of a loss equal to our maximum exposure to be remote and, accordingly 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 affect the fair value or risk of our variable interests in these variable interest entities.

Impairment Losses and Other Costs

Available for Sale Securities

We evaluated for impairment certain of our investments in equity securities during the sixnine months ended JuneSeptember 30, 2009. The investments we evaluated included our nuclear decommissioning trust fund assets and other marketable securities. We record an impairment charge if an investment has experienced a decline in fair value to a level less than ourits carrying value and the decline is "other than temporary."

        In making this determination, we evaluate the reasons for an investment's decline in value, the extent and duration of that decline, and factors that indicate whether and when the value will recover. For securities held in our nuclear decommissioning trust fund for which the market value is below book value, the decline in fair value is considered other than temporary and we write them down to fair value. We discuss our impairment policy for our nuclear decommissioning trust fund assets and other marketable securities in more detail inNote 1 to our 2008 Annual Report on Form 10-K.

        The fair values of certain of our marketable securities and certain of the securities held in our nuclear decommissioning trust fund declined below book value. As a result, we recorded a $1.9$0.2 million pre-tax impairment charge for the quarter ended JuneSeptember 30, 2009 and a $62.4$62.6 million pre-tax impairment charge for the sixnine months ended JuneSeptember 30, 2009 for our nuclear decommissioning trust fund assets in the "Other income (expense)" line in our Consolidated Statements of Income (Loss). In addition, we recorded all other changes in the fair value of our nuclear decommissioning trust fund assets that are not impaired in other comprehensive (loss) income. We also recorded an impairment charge of $0.5 million for other marketable securities during the sixnine months ended JuneSeptember 30, 2009.

        The estimates we utilize in evaluating impairment of our available for sale securities require judgment and the evaluation of economic and other factors that are subject to variation, and the impact of such variations could be material.

Equity Method Investments

Shipping Joint Venture

We record an impairment if an equity method investment has experienced a decline in fair value to a level less than our carrying value and the decline is "other than temporary." During the quarter ended June 30, 2009, we contemplated several potential courses of action together with our partner relating to the strategic direction of our shipping joint venture and our continuing involvement. This led to a decision to explore a plan to sell our 50% interest to a party related to our joint venture partner for negligible proceeds. During July 2009, a definitive purchase and sale agreement was executed between the parties and we expect the transaction to closeclosed in the third quarter of 2009. Upon completion, we willWe have no further continuing involvement associated within the activities of the joint venture.

        As a result of the events that occurred during the second quarter of 2009, it became apparentwe concluded that a decline inthe fair value of our investment had declined to a level below the carrying value existedat June 30, 2009 and that this decline was "other than temporary." As such, we recorded a pre-tax impairment charge at June 30, 2009 of $59.0 million associated with our equity investment in our shipping joint

venture within the "Impairment losses and other costs" line in our Consolidated Statements of Income (Loss), and reported the charge in our merchant energy business results for the second quarter of 2009.

Constellation Energy Partners LLC

As of March 31, 2009, the fair value of our investment in Constellation Energy Partners LLC (CEP) based upon its closing unit price was $10.0 million, which was lower than its carrying value of $24.0 million.

        The decline in fair value of our investment in CEP reflected a number of other factors, including:

        As a result of evaluating these factors, we determined that the decline in the value of our investment iswas other than temporary. Therefore, we recorded a $14.0 million pre-tax impairment charge at March 31, 2009 to write-down our investment to fair value. We recorded this charge in "Impairment losses and other costs" in our Consolidated Statements of Income (Loss). We did not record an impairment charge in the second quarteror third quarters of 2009. To the extent that the market price of our investment declines further in future quarters, we may record additional write-downs if we determine that those additional declines are other than temporary.

Other Costs

During the quarter and sixnine months ended JuneSeptember 30, 2009, we recorded $8.2$7.5 million and $22.3$29.8 million pre-tax charges, respectively, in the "Impairment losses and other costs" line in our Consolidated Statements of Income (Loss) primarily related to certain to:

Workforce Reduction Costs

We incurred workforce reduction costs during the six months ended June 30,fourth quarter of 2008, primarily related to workforce reduction efforts across all of our operations (Q4 2008 Program), and during the first quarter of 2009, primarily related to the divestiture of a majority of our international commodities operation as well as some smaller restructurings elsewhere in our organization. Weorganization (Q1 2009 Program). For the Q1 2009 Program, we recognized an $11.2$11.6 million pre-tax charge during the sixnine months ended JuneSeptember 30, 2009 related to the elimination of approximately 180 positions. We expect both of these restructurings will be completed within the next 12 months.months of their initiation.

Earnings Per Share

Basic earnings per common share (EPS) is computed by dividing earnings applicablenet income (loss) attributable to common stock by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

        Our dilutive common stock equivalent shares consist of stock options and other stock-based compensation awards. The following table presents stock options that were not dilutive and were excluded from the computation of diluted EPS in each period, as well as the dilutive common stock equivalent shares:

        We issued to MidAmerican 19,897,322 shares of Constellation Energy's common stock upon the conversion of the Series A Preferred Stock, which happenedoccurred upon the termination of the merger agreement with MidAmerican on December 17, 2008. We discuss the conversion feature of the Series A Preferred Stock in more detail inNote 9 of our 2008 Annual Report on Form 10-K. These additional shares impacted our earnings per share for the quarter and sixnine months ended JuneSeptember 30, 2009.

Acquisition

CLT Efficient Technologies Group

On July 1, 2009, we acquired CLT Efficient Technologies Group (CLT). We include CLT as part of our other nonregulated businesses and have reported its results of operations in our consolidated financial statements since the date of acquisition. CLT is an energy services company that provides energy performance contracting and energy efficiency engineering services.

        We acquired 100% ownership of CLT for $21.8 million, including direct costs, of which $20.8 million was paid in cash at closing.

        The total consideration was allocated to the net assets acquired as follows:

1 Goodwill is 100% deductible for tax purposes.

        Our initial purchase price allocation is based on preliminary estimates, and the purchase price is subject to adjustments, which could impact our purchase price allocation.

        The pro-forma impact of the CLT acquisition would not have been material to our results of operations for the quarter and nine months ended September 30, 2009 and 2008.

Divestitures

In 2009, we continued to implement many of the strategic initiatives we identified in 2008 to improve liquidity and reduce our business risk. We discuss these initiatives in theStrategy section of our 2008 Annual Report on Form 10-K.

        The transactions to sell a majority of our international commodities, our Houston-based gas trading and other operations were structured in two parts:

        Under the TRS, we entered into offsetting trades with the buyers that matched the terms of the remaining third party contracts for which we were unable to complete assignment to the buyers as of the transaction dates. This structure transferred the risks associated with changes in commodity prices as of the transaction dates to the buyers in all instances. However, the trades under the TRS are newly executed transactions, and we remain the principal under both the unassigned third party trades and the matching trades with the buyers under the TRS with no right of either financial or legal offset. We continue to pursue the assignment of these remaining contracts to the buyers.

        The matching contracts under the TRS include both derivatives and non-derivatives and were executed at prices that differed from market prices at closing, which resulted in a net cash payment to/from the buyers. We recorded the underlying contracts at fair value on a gross basis as assets or liabilities in our Consolidated Balance Sheets depending on whether the contract prices were above- or below-market prices at closing. As a result, the derivative contracts have been included in "Derivative Assets and Liabilities" and the nonderivative contracts have been included in "Unamortized Energy Contract Assets and Liabilities." The derivative


Table of Contents

contracts are subject to mark-to-market accounting until they are realized or assigned. The nonderivative contracts will be amortized into earnings as the underlying contracts are realized, or sooner if those contracts are assigned.

        We record the cash proceeds we pay or receive at the inception of energy purchase and sale contracts based upon


Table of Contents

whether the contracts are in-the-money or out-of-the-money as follows:

In-the-money contracts—proceeds paid

 Investing Outflow

Out-of-the-money contracts—proceeds received

 
Financing Inflow
 

        After inception, we record the cash flows from all energy purchase and sale contracts as operating activities, except for out-of-the-money derivative contracts that were liabilities at inception. We record the ongoing cash flows from these out-of-the-money derivative contracts as financing activities, regardless of whether they are purchase or sale contracts.

International Commodities Operation

In January 2009, we entered into a definitive agreement to sell a majority of our international commodities operation. We completed this transaction on March 23, 2009 and recognized the following impacts during the sixnine months ended JuneSeptember 30, 2009:

        We removed the contracts that were assigned from our balance sheet,Consolidated Balance Sheet, paid the buyer approximately $90 million, and reflected the impact of this payment on our working capital in the operating activities section of our Consolidated Statements of Cash Flows.

        The net cash payment to the buyer upon completion of the TRS was $2.5 million. As part of the consideration, we acquired matching nonderivative contracts that resulted in a net liability of approximately $75 million, which will be amortized into earnings as the underlying contracts are realized, or sooner if the original nonderivative contracts are assigned.

        We have reflected the contracts under the TRS on a gross basis in cash flows from investing and financing activities in our Consolidated Statements of Cash Flows as follows:

Six Months Ended June 30, 2009 
 
 (In millions)
 

Investing activities—Contract and portfolio acquisitions

        In addition to the March 23, 2009 transaction for a majority of our international commodities operation, on June 30, 2009 we completed the sale of a uranium market participant that we owned. We received cash proceeds of approximately $43 million and recorded a $27.2 million loss on this sale. This loss from our merchant energy segment is included in the "Net (loss) gain on divestitures" line in our Consolidated Statements of Income (Loss). for the nine months ended September 30, 2009.

Houston-Based Gas and Other Trading Operations

On February 3, 2009, we entered into a definitive agreement to sell our Houston-based gas trading operation. We transferred control of this operation on April 1, 2009. In addition, in the second quarter of 2009 we also sold certain other trading operations. In total, we received proceeds of approximately $56$61 million, and recorded a $102.4$102.7 million net loss on these sales in the quarternine months ended JuneSeptember 30, 2009. The net loss on sale primarily relates to nonderivative accrual contracts, which were not recorded on our Consolidated Balance Sheet, the cost associated with disposing of an entire portfolio and not merely individual contracts, and the cost of capital, including contingent capital, to support the operation.

        The matching derivative and nonderivative transactions under the TRS discussed above were executed at prices that differed from market prices at closing. As a result, we record the ongoing cash flows related to the out-of-the-money derivative contracts that were liabilities at inception as financing cash flows in accordance with SFAS No. 149.flows. This resulted in cash outflows related to financing activities of $378.0 million and $695.4$818.7 million in our

Consolidated Statements of Cash Flows for the quarter and sixnine months ended JuneSeptember 30, 2009 respectively, associated with derivative liabilities that were out-of-the-money.

        The net cash receipt from the buyers upon completion of the TRS was $91.9 million in the second quarter of 2009. We have reflected these contracts on a gross basis in

        In addition, we incurred other costs of $1.5 million and $5.5 million for the quarter and sixnine months ended JuneSeptember 30, 2009, respectively, related to leasehold improvements, furniture, computer hardware and software costs, which are recorded as part of "Impairment losses and other costs" on our Consolidated Statements of Income (Loss).

        On April 1, 2009, we executed an agreement with the buyer of our Houston-based gas trading operation under which the buyer will provide us with the gas supply needed to support our retail gas customer supply business through March 31, 2011. This agreement was structured such that our requirements to post collateral are reduced. The supplier has liens on the assets of the retail gas supply business as well as our investment in the stock of these entities to secure our obligations under the gas supply agreement. In connection with this agreement, we posted approximately $160 million of collateral. This was subsequently reduced to $100 million. The initial $160 million posted represents approximately 25 percent of the previous collateral requirements to support this operation. We discuss the impact of the gas supply agreement on our retail gas customer supply business in more detail on page 12.13.

Shipping Joint Venture

As previously discussed in theImpairment Losses and Other Costs footnote, we completed the sale of our equity investment in a shipping joint venture during the third quarter of 2009. No gain or loss was recognized on the sale.

Investments Classified as Available-for-Sale

We classify the following investments as available-for-sale:

        This means we do not expect to hold these investments to maturity, and we do not consider them trading securities. We record these investments at fair value on our Consolidated Balance Sheets.

        We show the fair values, gross unrealized gains and losses, and adjusted cost basis for all of our available-for-sale securities in the following tables. We use specific identification to determine cost in computing realized gains and losses.

Information by Operating Segment

Our reportable operating segments are—Merchant Energy, Regulated Electric, and Regulated Gas:

        Our remaining nonregulated businesses:

        Prior to June 30, 2009, our merchant energy business segment included additional activities that have been divested as part of our strategy to improve our liquidity and reduce our business risk. The divested activities include:

        Additionally, we entered into an Investment Agreement with EDF on December 17, 2008.        SeeNote 15 page 11 for discussion of our 2008 Annual Report on Form 10-K for more detail on the Investment Agreementtransaction with EDF.

        We believe that the successful execution of these initiatives,divestitures, as well as our other initiatives that we have undertaken to reduce risk in our merchant energy business, have reduced our exposure to activities that require contingent capital support and improved our liquidity. In turn,As a result of these divestitures and other initiatives, as well as the closing of our transaction with EDF, the results for our merchant energy business segment will be materially different from prior periods. We discuss these strategies and their effect on liquidity inNote 8 of our 2008 Annual Report on Form 10-K.

        Our Merchant Energy, Regulated Electric, and Regulated Gas reportable segments are strategic businesses based principally upon regulations, products, and services that require different technologies and marketing strategies. We evaluate the performance of these segments based on net income. We account for intersegment revenues using market prices. A summary of information by operating segment is shown in the table below.

Total assets decreased approximately $2.3$2.6 billion during the sixnine months ended JuneSeptember 30, 2009. The decrease primarily relates to:

These decreases were offset by a $194.1 million increase in the value of our nuclear decommissioning trust fund assets.

Our allowance for uncollectible accounts receivable increased $19.6decreased $59.7 million from December 31, 2008 to JuneSeptember 30, 2009. This increasedecrease is primarily attributable to a decrease of $80.3 million at our merchant energy business, partially offset by an increase of $18.7 million at our regulated electric and gas businesses. InThe decrease in the allowance for uncollectibles at our merchant energy business is primarily driven by a write-off of accounts receivable balances of certain customers and the related allowance balance that were established primarily during 2008 for certain counterparties that encountered financial difficulty. This decrease is partially offset by an increase at our regulated electric and gas businesses primarily due to a second quarter 2009 Maryland PSC ruling and the economic downturn which continues to cause a decreased ability of customers to pay their utility bills. The Maryland PSC ruling in the second quarter of 2009 the Maryland PSC issued a ruling which delayed BGE's ability to terminate service to customers with arrearages and offeredrequired BGE to offer those customers the option to enter into extended payment plans.

Financing Activities

Credit Facilities and Short-term Borrowings

Our short-term borrowings may include bank loans, commercial paper, and bank lines of credit. Short-term borrowings mature within one year from the date of issuance. We pay commitment fees to banks for providing us lines of credit. When we borrow under the lines of credit, we pay market interest rates.


Table of Contents

Constellation Energy

Constellation Energy had bank and other lines of credit under committed unsecured credit facilities totaling $5.6$5.8 billion at JuneSeptember 30, 2009 for short-term financial needs. We enter into these facilities to ensure adequate liquidity to support our operations.

        Our liquidity requirements are funded with credit facilities and cash. We fund our short-term working capital needs with existing cash and with our credit facilities, many of which support direct cash borrowings and the issuance of commercial paper, if available. We also use our credit facilities to support the issuance of letters of credit, primarily for our merchant energy business.

        These facilities can issue letters of credit, commercial paper, if available, and/or cash borrowings up to approximately $5.6 billion as shown below. As of June 30, 2009, we had approximately $2.8 billion in letters of credit issued against those facilities.

We have also included in the table below the pro forma effect on our credit facilities which are reduced or terminated uponas of September 30, 2009 and pro forma following the closingcompletion of the transactions contemplated by the Investment Agreementtransaction with EDF, which is expected to occur in the fourth quarter of 2009:EDF:

1 Size of facility may be reduced by proceeds received from certain securities offerings or asset sales.

2 Excludes commodity-linked credit facility discussed below due to its contingent nature.

        During the third quarter of 2009, we executed a committed five year bilateral credit facility that allows for a maximum capacity of $500 million. This facility can be used to issue letters of credit in support of our collateral obligations. At September 30, 2009 and November 3, 2009, this facility had committed capacity of $250 million and $500 million, respectively. The facility partially replaces a portion of our credit facilities that terminate upon closing of the transaction with EDF.

        During the third quarter of 2009, we also entered into a five year commodity-linked credit facility that allows for the issuance of letters of credit up to a maximum capacity of $500 million. We could increase the maximum facility size to $750 million or alternatively enter into an additional $250 million bilateral facility if certain conditions are met, including the closing of the transaction with EDF. This commodity-linked facility is designed to help manage our contingent collateral requirements associated with the hedging of our Customer Supply operations because its capacity increases as natural gas price levels decrease compared to a reference price that is adjusted periodically. As of September 30, 2009, there were no letters of credit outstanding under this facility.

BGE

As of September 30, 2009, BGE has a $400.0 million five-year revolving credit facility expiring in 2011. BGE can borrow directly from the banks, use the facility to allow commercial paper to be issued, if available, or issue letters of credit. On October 29, 2009, BGE expanded its borrowing capacity to $575 million. The size of the facility may be increased up to $600 million with additional commitments by lenders. As of JuneSeptember 30, 2009, BGE had $0.5 million in letters of credit issued under this facility.

        In addition, at JuneSeptember 30, 2009, BGE had $339.9$334.9 million in commercial paper outstanding.

Debt

Constellation Energy

In July 2009, we entered into a three year asset-based lending agreement associated with certain upstream gas properties that we own. At September 30, 2009, the borrowing base committed under the facility was $30 million, of which $12.1 million has been utilized and reflected in "Long-term debt" in our Consolidated Balance Sheets. The size of the facility may be increased up to $200 million with additional commitments by the lenders. At October 30, 2009, the borrowing base of the facility increased to $100 million with the commitments of additional lenders. Any debt issued under this facility is secured by the upstream gas properties, and the lenders do not have recourse against Constellation Energy in the event of a default. Interest is payable quarterly in March, June, September, and December.

        This asset-based lending agreement contains a provision that requires certain of our entities that own our upstream gas properties to maintain a current ratio of one-to-one. As of September 30, 2009, these entities were in compliance with this provision.

        Upon the close of the EDF transaction, the amount and composition of our liquidity will change due to the reduction in credit facilities discussed on the previous page, as well as the receipt of net cash proceeds from the transaction.

        The net proceeds from this transaction are expected to be approximately $2.2 billion after repayment of the EDF preferred stock and the payment of taxes. We anticipate using these proceeds to reduce up to $850 million of our long-term debt, as well as for other general corporate purposes, including payments related to BGE under the Maryland PSC order dated October 30, 2009. These net proceeds will partially offset the reduction in credit facilities, although our net available liquidity will be reduced.

Other Sources of Liquidity

In December 2008, we executed an Investment Agreement with EDF that includes an asset put arrangement that provides us with an option at any time through December 31, 2010 (or the termination of the Investment Agreement by EDF if we breach that agreement) to sell certain non-nuclear generation assets, at pre-agreed prices, to EDF for aggregate proceeds of no more than $2 billion pre-tax, or approximately $1.4 billion after-tax. The amount of after-tax proceeds will be impacted by the assets actually sold and the related tax impacts at that time.

        Exercise of the put arrangement is conditioned upon the receipt of regulatory approvals and third-party consents, the absence of any material liens on such assets, and the absence of a material adverse effect, as defined in the Investment Agreement. During April 2009, we received regulatory approvals and consents for the majority of the assets covered by the put arrangement. As of JuneSeptember 30, 2009, we have approximately $1.1 billion after-tax of liquidity available through the put arrangement. We expect to receive regulatory approval for an additional asset in the first quarter of 2010, which will increase the net after-tax


Table of Contents

liquidity from the put arrangement to approximately $1.4 billion.

        We are actively seekingcontinue to increase available liquidity and to reduce our business risk. Specifically, we are reducing capital spending and ongoing expenses, scaling down the expected variability in long-term earnings and short-term collateral usage, and limiting our exposure to business activities that require contingent capital support. During 2009, we made progress on several otherof these initiatives as discussed in more detail in theDivestitures section beginning on page 1516 and theVariable Interest Entities section on page 12.13. As of JuneSeptember 30, 2009, we have realized substantially all of the $1 billion of the net reduction in collateral that was expected from the divestiture of these operations.

        We believe that the actions that we have taken and our current net available liquidity will be sufficient to support the ongoing liquidity requirements over the next 12 months. Our liquidity projections include assumptions for commodity price changes, which are subject to significant volatility, and we are exposed to certain operational risks that could have a significant impact on our liquidity.

Credit Facility Compliance and Covenants

The credit facilities of Constellation Energy and BGE have limited material adverse change clauses, none of which would prohibit draws under the existing facilities.

        Certain credit facilities of Constellation Energy contain a provision requiring Constellation Energy to maintain a ratio of debt to capitalization equal to or less than 65%. At JuneSeptember 30, 2009, the debt to capitalization ratio as defined in the credit agreements was 51%46%.

        UnderUpon the closing of our transaction with EDF, under our $3.85 billion and $1.23 billion credit facilities,facility (which reduces to $2.32 billion), we will be required to grant a lien on certain of our generating facilities and pledge our ownership interests in our nuclear business to the lenders upon the earlier of (i) the closing of the Investment Agreement with EDF or (ii) the date on which both the Investment Agreement is terminated and our Standard & Poors (S&P) or Fitch senior unsecured debt credit rating is below BBB- or our Moody's senior unsecured debt credit rating is below Baa3.lenders.

        Our $1.23 billion credit facility requires us to maintain consolidated earnings before interest, taxes, depreciation, and amortization to consolidated interest expense ratio of at least 2.75 when our S&P senior


Table of Contents

unsecured debt rating is BBB- or lower and our Moody's senior unsecured debt rating is Baa3 or lower. Compliance with the covenant iswas not required as of July 31,September 30, 2009 as S&P's senior unsecured debt rating iswas above BBB-. Since the $1.23 billion credit facility expires upon the earlier of the closing of the EDF transaction or November 12, 2009, the recent change in rating by S&P to BBB- will not require compliance with this covenant.

        The credit agreement of BGE contains a provision requiring BGE to maintain a ratio of debt to capitalization equal to or less than 65%. At JuneSeptember 30, 2009, the debt to capitalization ratio for BGE as defined in this credit agreement was 52%.

        The impact of a credit ratings downgrade on our financial ratios associated with our credit facility covenants would depend on our financial condition at the time of such a downgrade and on the source of funds used to satisfy the incremental collateral obligation resulting from a credit ratings downgrade. For example, if we were to use existing cash balances or exercise the put option with EDF to fund the cash portion of any additional collateral obligations resulting from a credit ratings downgrade, we would not expect a material impact on our financial ratios. However, if we were to issue long-term debt or use our credit facilities to fund any additional collateral obligations, our financial ratios could be materially affected. Failure by Constellation Energy, or BGE, to comply with these covenants could result in the acceleration of the maturity of the borrowings outstanding and preclude us from issuing letters of credit under these facilities.

Income Taxes

We compute the income tax expense (benefit) expense for each quarter based on the estimated annual effective tax rate for the year. The effective tax rate was 78.3%64.1% and 60.4%67.7% for the quarter and sixnine months ended JuneSeptember 30, 2009, respectively, compared to 38.0%33.4% and 36.1%41.1% for the same periods of 2008. The higher effective tax rate for the quarter and sixnine months ended JuneSeptember 30, 2009 reflects the impact of unfavorable nondeductible adjustments (primarily related to nondeductible dividends on the Series B Preferred Stock and the write-off of the unamortized debt discount on the Senior Notes) in relation to the lower estimated 2009 taxable income (primarily attributable to losses on the divestiture of a majority of our international commodities and our Houston-based gas trading operations).

        The BGE effective tax rate was 39.8%36.5% and 39.6%38.9% for the quarter and sixnine months ended JuneSeptember 30, 2009, respectively, compared to 33.1%43.4% and 36.7%(73.1)% for the same periods of 2008. This reflects the impact of the lower 2008 taxable income related to the Maryland settlement agreement, which increased the relative impact of favorable permanent tax adjustments on BGE's 2008 effective tax rate.

        Increases in current year and reductions in prior year tax positions are primarily due to unrecognized tax benefits for repair and depreciation deductions measured at amounts

Statutes of limitations lapsed for 2003 and 2004Increases in prior year tax positions relatedare primarily due to Maryland taxes onBGE repair and depreciation deductions, which have not been the gas plant sale that occurred in 2006.subject of an IRS examination.

        If the total amount of unrecognized tax benefits of $184.1$297.2 million were ultimately realized, our income tax expense would decrease by approximately $158$173 million. However, the $158$173 million includes state tax refund claims of approximately $48$51 million that have been disallowed by tax authorities and we believe that there is a remote likelihood of ultimately realizing any benefit from these refund claim amounts. These state refund claims may be resolved by December 31, 2009. For this reason, we believe it is reasonably possible that reductions to our total unrecognized tax benefits in the range of $40 to $50 million may occur by June 30,March 31, 2010, although these reductions are not expected to materially impact income tax expense.

Taxes Other Than Income Taxes

BGE collects from certain customers franchise and other taxes that are levied by state or local governments on the sale or distribution of gas and electricity. We include these types of taxes in "Taxes other than income taxes" in our Consolidated Statements of Income (Loss). Some of these taxes are imposed on the customer and others are imposed on BGE. We account for the taxes imposed on the customer on a net basis, which means we do not recognize revenue and an offsetting tax expense for the taxes collected from customers. We account for the taxes imposed on BGE on a gross basis, which means we recognize revenue for the taxes collected from customers. Accordingly, we record the taxes accounted for on a gross basis as revenues in the accompanying Consolidated Statements of Income (Loss) for BGE as follows:

Commitments and Contingencies

We have made substantial commitments in connection with our merchant energy, regulated electric and gas, and other nonregulated businesses. These commitments relate to:

        Our merchant energy business enters into various long-term contracts for the procurement and delivery of fuels to supply our generating plant requirements. In most cases, our contracts contain provisions for price escalations, minimum purchase levels, and other financial commitments. These contracts expire in various years between 2009 and 2028. In addition, our merchant energy business enters into long-term contracts for the capacity and transmission rights for the delivery of energy to meet our physical obligations to our customers. These contracts expire in various years between 2009 and 2030.

        Our merchant energy business also has committed to long-term service agreements and other purchase commitments for our plants.

        Our regulated electric business enters into various long-term contracts for the procurement of electricity. As of JuneSeptember 30, 2009, these contracts expire during 2009,between 2010 and 20112012 and represent BGE's estimated requirements for residential customers as follows:

        The cost of power under these contracts is recoverable under the Provider of Last Resort agreement reached withsettlement approved by the Maryland PSC.PSC and in accordance with Maryland law.

        Our regulated gas business enters into various long-term contracts for the procurement, transportation, and storage of gas. Our regulated gas business has gas procurement contracts that expire between 2009 and 2011, and transportation and storage contracts that expire between 20122010 and 2027. The cost of gas under these contracts is recoverable under BGE's gas cost adjustment clause discussed inNote 1 of our 2008 Annual Report on Form 10-K.

        Our other nonregulated businesses have committed to gas purchases, as well as to contribute additional capital for construction programs and joint ventures in which they have an interest.

        We have also committed to long-term service agreements and other obligations related to our information technology systems.

        At JuneSeptember 30, 2009, the total amount of commitments was $4,973.4$5,371.9 million. These commitments are primarily related to our merchant energy business.


Long-Term Power Sales Contracts

We enter into long-term power sales contracts in connection with our load-serving activities. We also enter into long-term power sales contracts associated with certain of our power plants. Our load-serving power sales contracts extend for terms through 2019 and provide for the sale of energy to electricity distribution utilities and certain retail customers. Our power sales contracts associated with power plants we own extend for terms into 20152017 and provide for the sale of all or a portion of the actual output of certain of our power plants. Substantially all long-term contracts were executed at pricing that approximated market rates, including profit margin, at the time of execution.


Contingencies

Litigation

In the normal course of business, we are involved in various legal proceedings. We discuss the significant matters below.

Merger with MidAmerican

Beginning September 18, 2008, seven shareholders of Constellation Energy filed lawsuits in the Circuit Court for Baltimore City, Maryland challenging the then-pending merger with MidAmerican. Four similar suits were filed by other shareholders of Constellation Energy in the United States District Court for the District of Maryland.

        The lawsuits claim that the merger consideration was inadequate and did not maximize value for shareholders, that the sales process leading up to the merger was

unreasonably short and procedurally flawed, and that unreasonable deal protection devices were agreed to in order to ward off competing bids and coerce shareholders into accepting the merger. The federal lawsuits also assert that the conversion of the Preferred Stock issued to MidAmerican into debt is not permitted under Maryland law. The lawsuits seek declaratory judgments establishing the unenforceability of the merger based on the alleged breaches of duty, injunctive relief to enjoin the merger, rescission of the merger or rescissory damages, the imposition of a constructive trust in favor of shareholders of any benefits received by the individual members of the


Table of Contents

Board of Directors of Constellation Energy, and reasonable costs and expenses, including attorney's fees.

        The termination of the MidAmerican merger renders moot the claims attempting to enjoin the merger with MidAmerican. One of the federal merger cases was voluntarily dismissed on December 31, 2008. The other federal merger cases filed in the United States District Court for the District of Maryland were dismissed as moot on May 27, 2009. Plaintiffs' counsel in six of the seven state merger cases have indicated that in light of the termination of the MidAmerican merger they will be filing dismissals without prejudice to their MidAmerican merger claims. In addition, on October 27, 2009 certain counsel in the state merger cases jointly moved for approval of a settlement regarding claims for attorneys' fees, which is pending and subject to court approval. We believe there are meritorious defenses to the remainingany claims or requests for relief.relief that might possibly remain regarding this matter. However, we are unable at this time to determine the ultimate outcome of these lawsuits or their possible effect on our financial results.

Securities Class Action

Three federal securities class action lawsuits have been filed in the United States District Courts for the Southern District of New York and the District of Maryland between September 2008 and November 2008. The cases were filed on behalf of a proposed class of persons who acquired publicly traded securities, including the Series A Junior Subordinated Debentures (Debentures), of Constellation Energy 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 Energy, a number of its present or former officers or directors, and the underwriters violated the securities laws by issuing a false and misleading registration statement and prospectus in connection with Constellation Energy's June 27, 2008 offering of Debentures. The securities class actions also allege that Constellation Energy issued false or misleading statements or was aware of material undisclosed information which contradicted public statements including in connection with its announcements of financial results for 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 seek, among other things, certification of the cases as class actions, compensatory damages, reasonable costs and 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 there to the District of Maryland, and the actions have since been transferred for coordination with the securities class action filed there. On June 18, 2009, the court appointed a lead plaintiff, who we expect to filefiled a consolidated amended complaint.complaint on September 17, 2009. We are unable at this time to determine the ultimate outcome of the securities class actions or their possible effect on our, or BGE's financial results.

ERISA Actions

In the fall of 2008, multiple class action lawsuits were filed in the United States District Courts for the District of Maryland and the Southern District of New York against Constellation Energy; Mayo A. Shattuck III, Constellation Energy's Chairman of the Board, President and Chief Executive Officer; and others in their roles as fiduciaries of the Constellation Energy Employee Savings Plan. The actions, which have been consolidated into one action in Maryland (the Consolidated Action), allege that the defendants, in violation of various sections of ERISA, breached their fiduciary duties to prudently and loyally manage Constellation Energy Savings Plan's assets by designating Constellation Energy common stock as an investment, by failing to properly provide accurate information about the investment, by failing to avoid conflicts of interest, by failing to properly monitor the investment and by failing to properly monitor other fiduciaries. The plaintiffs seek to compel the defendants to reimburse the plaintiffs and the Constellation Energy Savings Plan for all losses resulting from the defendants' breaches of fiduciary duty, to impose a constructive trust on any unjust enrichment, to award actual damages with pre- and post-judgment interest, to award appropriate equitable relief including injunction and restitution and to award costs and expenses, including attorneys' fees. We are unable at this time to determine the ultimate outcome of the Consolidated Action or its possible effects on our, or BGE's, financial results.

Mercury

Since September 2002, BGE, Constellation Energy, and several other defendants have been involved in numerous actions filed in the Circuit Court for Baltimore City, Maryland alleging mercury poisoning from several sources, including coal plants formerly owned by BGE. The plants are now owned by a subsidiary of Constellation Energy. In addition to BGE and Constellation Energy, approximately 11 other defendants, consisting of pharmaceutical


Table of Contents

companies, manufacturers of vaccines, and manufacturers of Thimerosal have been sued. Approximately 70 cases, involving claims related to approximately 132 children, have been filed to date, with each claimant seeking $20 million in compensatory damages, plus punitive damages, from us.


Table of Contents

        In rulings applicable to all but three of the cases, involving claims related to approximately 47 children, the Circuit Court for Baltimore City dismissed with prejudice allThe claims against BGE and Constellation Energy.Energy have been dismissed in all of the cases either with prejudice based on rulings by the Court or without prejudice based on voluntary dismissals by the plaintiffs' counsel. Plaintiffs may attempt to pursue appeals of the rulings in favor of BGE and Constellation Energy once the cases are finally concluded as to all defendants. We believe that we have meritorious defenses and intend to defend the remaining actions vigorously. However, we cannot predict the timing, or outcome, of these cases, or their possible effect on our, or BGE's, financial results.

Asbestos

Since 1993, BGE and certain Constellation Energy subsidiaries have been involved in several actions concerning asbestos. The actions are based upon the theory of "premises liability," alleging that BGE and Constellation Energy knew of and exposed individuals to an asbestos hazard. In addition to BGE and Constellation Energy, numerous other parties are defendants in these cases.

        Approximately 512499 individuals who were never employees of BGE or Constellation Energy have pending claims each seeking several million dollars in compensatory and punitive damages. Cross-claims and third-party claims brought by other defendants may also be filed against BGE and Constellation Energy in these actions. To date, most asbestos claims which have been resolved have been dismissed or resolved without any payment and a small minority have been resolved for amounts that were not material to our financial results.

        BGE and Constellation Energy do not know the specific facts necessary to estimate their potential liability for these claims. The specific facts we do not know include:

        Until the relevant facts are determined, we are unable to estimate what our, or BGE's, liability might be. Although insurance and hold harmless agreements from contractors who employed the plaintiffs may cover a portion of any awards in the actions, the potential effect on our, or BGE's, financial results could be material.

Environmental Matters

Solid and Hazardous Waste

In 1999, the EPA proposed to add the 68th Street Dump in Baltimore, Maryland to the Superfund National Priorities List, which is its list of sites targeted for clean-up and enforcement, and sent a general notice letter to BGE and 19 other parties identifying them as potentially liable parties at the site. In March 2004, we and other potentially responsible parties formed the 68th Street Coalition and entered into consent order negotiations with the EPA to investigate clean-up options for the site under the Superfund Alternative Sites Program. In May 2006, a settlement among the EPA and 19 of the potentially responsible parties, including BGE, with respect to investigation of the site became effective. The settlement requires the potentially responsible parties, over the course of several years, to identify contamination at the site and recommend clean-up options. BGE is fully indemnified by a wholly owned subsidiary of Constellation Energy for costs related to this settlement, as well as any clean-up costs. The clean-up costs will not be known until the investigation is closer to completion. However, thosecompletion, which is expected by mid-2010. The completed investigation will provide a range of remediation alternatives to the EPA, and the EPA is expected to select one of the alternatives by the end of the first quarter of 2011. The clean-up costs we incur could have a material effect on our financial results.

Air Quality

In May 2007, a subsidiary of Constellation Energy entered into a consent decree with the Maryland Department of the Environment to resolve alleged violations of air quality opacity standards at three fossil fuel plants in Maryland. The consent decree requires the subsidiary to pay a $100,000 penalty, provide $100,000 to a supplemental environmental project, and install technology to control emissions from those plants.

        In January 2009, the EPA issued a notice of violation (NOV) to a subsidiary of Constellation Energy, as well as the other owners and the operator of the Keystone coal-fired power plant in Shelocta, Pennsylvania. We hold an approximately 21% interest in the Keystone plant. The NOV alleges that the plant performed various capital projects beginning in 1984 without complying with the new source review permitting requirements of the Clean Air Act. The EPA also contends that the alleged failure to comply with those requirements are continuing violations under the plant's air permits. The EPA could seek civil penalties under the Clean Air Act for the alleged violations.

        The owners and operator of the Keystone plant are investigating the allegations and have entered into discussions with the EPA. We believe there are meritorious defenses to the allegations contained in the NOV. However, we cannot predict the outcome of this proceeding and it is not possible to determine our actual liability, if any, at this time.

Water Quality

In October 2007, a subsidiary of Constellation Energy entered into a consent decree with the Maryland Department of the Environment relating to groundwater contamination at a third party facility that was licensed to accept fly ash, a byproduct generated by our coal-fired plants. The consent decree requires the payment of a $1.0 million penalty, remediation of groundwater contamination resulting from the ash placement operations at the site, replacement of drinking water supplies in the vicinity of the site, and monitoring of groundwater conditions. We recorded a liability in our Consolidated Balance Sheets of approximately $7.9 million, which includes the $1 million penalty and our estimate of probable costs to remediate contamination, replace drinking water supplies, monitor groundwater conditions, and otherwise comply with the consent decree. We have paid approximately $4.1$4.4 million of these costs as of JuneSeptember 30, 2009, resulting in a remaining liability at JuneSeptember 30, 2009 of $3.8$3.5 million. We estimate that it is reasonably possible that we could incur additional costs of up to approximately $10 million more than the liability that we accrued.

Insurance

We discuss our nuclear and non-nuclear insurance programs inNote 12 of our 2008 Annual Report on Form 10-K.

Derivative Instruments

Nature of Our Business and Associated Risks

Our business activities primarily include our merchant energy business and our regulated electric and gas business. Our merchant energy business includes:

        Our regulated electric and gas businesses engage in electricity and gas transmission and distribution activities in Central Maryland at prices set by the Maryland PSC that are generally designed to recover our costs, including purchased fuel and energy. Substantially all of our risk management activities involving derivatives occur outside our regulated businesses.

        In carrying out our merchant energy business activities, we purchase and sell power, fuel, and other energy-related commodities in competitive markets. These activities expose us to significant risks, including market risk from price volatility for energy commodities and the credit risks of counterparties with which we enter into contracts. The sources of these risks include, but are not limited to, the following:

Objectives and Strategies for Using Derivatives

Risk Management Activities

To lower our exposure to the risk of unfavorable fluctuations in commodity prices, interest rates, and foreign currency rates, we routinely enter into derivative contracts, such as fixed-price forward physical purchase and sales contracts, futures, financial swaps, and option contracts traded in the over-the-counter markets or on exchanges, for hedging purposes. The objectives for entering into such hedging transactions primarily include:

Non-Risk Management Activities

In addition to the use of derivatives for risk management purposes, we also enter into derivative contracts for trading purposes primarily to achieve the following objectives:

Accounting for Derivative Instruments

The accounting requirements for derivatives requiresprovide for recognition of all qualifying derivative instruments on the balance sheet at fair value as either assets or liabilities.

Accounting Designation

We must evaluate new and existing transactions and agreements to determine whether they are derivatives, for which there are several possible accounting treatments. Mark-to-market is required as the default accounting treatment for all derivatives unless they qualify, and we specifically designate them, for one of the other accounting treatments. Derivatives designated for any of the elective accounting treatments must meet specific, restrictive criteria, both at the time of designation and on an ongoing basis. The permissible accounting treatments include:

        We discuss our accounting policies for derivatives and hedging activities and their impacts on our financial statements inNote 1 to our 2008 Annual Report on Form 10-K.

NPNS

We elect NPNS accounting for derivative contracts that provide for the purchase or sale of a physical commodity that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Once we elect NPNS classification for a given contract, we cannot subsequently change the election and treat the contract as a derivative using mark-to-market or hedge accounting.

Cash Flow Hedging

We generally elect cash flow hedge accounting for most of the derivatives that we use to hedge market price risk for our physical energy delivery activities because hedge accounting more closely aligns the timing of earnings recognition and cash flows for the underlying business activities. Management monitors the potential impacts of commodity price changes and, where appropriate, may enter into or close out (via offsetting transactions) derivative transactions designated as cash flow hedges.

Commodity Cash Flow Hedges

Our merchant energy business has designated fixed-price forward contracts as cash-flow hedges of forecasted sales of energy and forecasted purchases of fuel and energy for the years 2009 through 2016. Our merchant energy business had net unrealized pre-tax losses on these cash-flow hedges recorded in "Accumulated other comprehensive loss" of $1,845.3$1,323.1 million at JuneSeptember 30, 2009 and $2,614.9 million at December 31, 2008.

        We expect to reclassify $1,326.2$941.8 million of net pre-tax losses on cash-flow hedges from "Accumulated other comprehensive loss" into earnings during the next twelve months based on market prices at JuneSeptember 30, 2009. However, the actual amount reclassified into earnings could vary from the amounts recorded at JuneSeptember 30, 2009, due to future changes in market prices.

        When we determine that a forecasted transaction originally hedged has become probable of not occurring, we reclassify net unrealized gains or losses associated with those hedges from "Accumulated other comprehensive loss" to earnings. We recognized in earnings the following pre-tax amounts on such contracts:

        The pre-tax loss reclassified in 2009 resulted from the sale of a majority of our international commodities operation and our termination of certain contracts as part of our efforts to improve liquidity and reduce risk. The forecasted transactions associated with previously designated cash-flow hedge contracts were deemed probable of not occurring.

Interest Rate Swaps Designated as Cash Flow Hedges

We use interest rate swaps designated as cash flow hedges to manage our interest rate exposures associated with new debt issuances and to manage our exposure to fluctuations in interest rates on variable rate debt. The effective portion of gains and losses on these interest rate cash flow hedges, net of associated deferred income tax effects, is recorded in "Accumulated other comprehensive loss" in our Consolidated Statements of Comprehensive Income (Loss). We reclassify gains and losses on the hedges from "Accumulated other comprehensive loss" into "Interest expense" in our Consolidated Statements of Income (Loss) during the periods in which the interest payments being hedged occur.


Table of Contents

        Accumulated other comprehensive loss includes net unrealized pre-tax gains on interest rate cash-flow hedges of prior debt issuances totaling $12.1$11.9 million at JuneSeptember 30, 2009 and $12.0 million at December 31, 2008. We expect to reclassify $1.9$2.3 million of pre-tax net gains on these cash-flow hedges from "Accumulated other comprehensive loss" into "Interest expense" during the next twelve months. We had no hedge ineffectiveness on these swaps.


Table of Contents

Fair Value Hedging

We elect fair value hedge accounting for a limited portion of our derivative contracts including certain interest rate swaps and certain forward contracts and price and basis swaps associated with natural gas fuel in storage. The objectives for electing fair value hedging in these situations are to manage our exposure, to optimize the mix of our fixed and floating-rate debt, and to hedge the value of our natural gas in storage. We did not have any fair value hedges related to the value of our natural gas in storage during the second quarterand third quarters of 2009.

Interest Rate Swaps Designated as Fair Value Hedges

We use interest rate swaps designated as fair value hedges to optimize the mix of fixed and floating-rate debt. We record any gains or losses on swaps that qualify for fair value hedge accounting treatment, as well as changes in the fair value of the debt being hedged, in "Interest expense." We record changes in fair value of the swaps in "Derivative assets and liabilities" and changes in the fair value of the debt in "Long-term debt" in our Consolidated Balance Sheets. In addition, we record the difference between interest on hedged fixed-rate debt and floating-rate swaps in "Interest expense" in the periods that the swaps settle.

        During 2004, we entered into interest rate swaps qualifying as fair value hedges relating to $450 million of our fixed-rate debt maturing in 2012 and 2015, and converted this notional amount of debt to floating-rate. The fair value of these hedges was an unrealized gain of $40.4$46.8 million at JuneSeptember 30, 2009 and $55.9 million at December 31, 2008 and was recorded as an increase in our "Derivative assets" and an increase in our "Long-term debt." We had no hedge ineffectiveness on these interest rate swaps. On July 15, 2009, we terminated an interest rate swap relating to $50 million of the $450 million of our fixed-rate debt and received approximately $4.5 million in cash. This transaction will bewas recorded in the third quarter of 2009.

        In addition, we did not recognize any gain or loss during the quarter or sixnine months ended JuneSeptember 30, 2009 and 2008 relating to changes in value for the portion of our fair value hedges excluded from our hedge effectiveness assessment.

Mark-to-Market

We generally apply mark-to-market accounting for risk management and trading activities for which changes in fair value more closely reflect the economic performance of the underlying business activity. However, we also use mark-to-market accounting for derivatives related to the following physical energy delivery activities:


Quantitative Information About Derivatives and Hedging Activities

Background

Effective January 1, 2009, we adopted SFAS No. 161,Disclosures About Derivative Instrumentsan accounting standard related to disclosures about derivative instruments and Hedging Activities, (SFAS No. 161). SFAS No. 161hedging activities. This standard does not change the accounting for derivatives; rather, it requires expanded disclosure about derivative instruments and hedging activities regarding:


Table of Contents

Balance Sheet Tables

We present our derivative assets and liabilities in our Consolidated Balance Sheets on a net basis, including cash collateral, whenever we have a legally enforceable master netting agreement with a counterparty to a derivative contract. We use master netting agreements whenever possible to manage and substantially reduce our potential counterparty credit risk. The net presentation in our Consolidated Balance Sheets reflects our actual credit exposure after giving effect to the beneficial effects of these agreements and cash collateral, and our credit risk is reduced further by other forms of collateral.

        The following table provides information about the types of market risks we manage using derivatives. This table only includes derivatives and does not reflect the price risks we are hedging that arise from physical assets or nonderivative accrual contracts within our generating plants, customer supply, and global commodities activities.


Table of Contents

        As discussed more fully following the table, we present this information by disaggregating our net derivative assets and liabilities into gross components on a contract-by-contract basis before giving effect to the risk-reducing benefits of master netting arrangements and collateral. As a result, we must present each individual contract as an "asset value" if it is in the money or a "liability value" if it is out of the money, regardless of whether the individual contracts offset market or credit risks of other contracts in full or in part. Therefore, the gross amounts in this table do not reflect our actual economic or credit risk associated with derivatives. This gross presentation is intended only to show separately the various derivative contract types we use, such as commodities, interest rate, and foreign exchange.

        In order to identify how our derivatives impact our financial position, at the bottom of the table we provide a reconciliation of the gross fair value components to the net fair value amounts as presented in theFair Value Measurements section of this note and our Consolidated Balance Sheets.

        The gross asset and liability values in the table below are segregated between those derivatives designated in qualifying hedge accounting relationships and those not designated in hedge accounting relationships. Derivatives not designated in hedging relationships include our retail gas customer supply operation, economic hedges of accrual activities, the international commodities and Houston-based gas trading operations that we have divested, and risk management and trading activities which we have substantially curtailed as part of our effort to reduce risk in our business. We use the end of period accounting designation to determine the classification for each derivative position.

        The magnitude of and changes in the gross derivatives components in this table do not indicate changes in the level of derivative activities, the level of market risk, or the level of credit risk. The primary factors affecting the magnitude of the gross amounts in the table are changes in commodity prices and the total number of contracts. If commodity prices change, the gross amounts could increase, even if the level of contracts stays the same, because separate presentation is required for contracts that are in the money from those that are out of the money. As a result, the gross amounts of even fully hedged positions could increase if prices change. Additionally, if the number of contracts increases, the gross amounts also could increase. Thus, the execution of new contracts to reduce economic risk could actually increase the gross amounts in the table because of the requirement to present the gross value of each individual contract separately.


Table of Contents

        The primary purpose of this table is to disaggregate the risks being managed using derivatives. In order to achieve this objective, we prepare this table by separating each individual derivative contract that is in the money from each contract that is out of the money and present such amounts on a gross basis, even for offsetting contracts that have identical quantities for the same commodity, location, and delivery period. We must also present these components excluding the substantive credit-risk reducing effects of master netting agreements and collateral. As a result, the gross "asset" and "liability" amounts for each contract type far exceed our actual economic exposure to commodity price risk and credit risk. Our actual economic exposure consists of the net derivative position combined with our nonderivative accrual contracts, such as those for load-serving, and our physical assets, such as our power plants. Our actual derivative credit risk exposure after master netting agreements and cash collateral is reflected in the net fair value amounts shown at the bottom of the table above. Our total economic and credit exposures, including derivatives, are managed in a comprehensive risk framework that includes risk measures such as economic value at risk, stress testing, and maximum potential credit exposure.

Gain and (Loss) Tables

The following tables below summarize the gain and loss impacts of our derivative instruments segregated into the following categories:

        The tables only include this information for derivatives and do not reflect the related gains or losses that arise from generation and generation-related assets, nonderivative accrual contracts, or NPNS contracts within our Generation, Customer Supply, and Global Commodities activities, other than fair value hedges, for which we separately show the gain or loss on the hedged asset or liability. As a result, for mark-to-market and cash-flow hedge derivatives, these tables only reflect the impact of derivatives themselves and therefore do not necessarily include all of the income statement impacts of the transactions for which derivatives are used to manage risk. For a more complete discussion of how derivatives affect our financial performance, see our accounting policy for Revenues, Fuel and Purchased Energy Expenses, and Derivatives and Hedging Activities inNote 1 to our 2008 Annual Report on Form 10-K.

        The following table presents gains and losses on derivatives designated as cash flow hedges. As discussed more fully in our accounting policy, we record the effective portion of unrealized gains and losses on cash flow hedges in Accumulated Other Comprehensive Loss until the hedged forecasted transaction affects earnings. We record the ineffective portion of gains and losses on cash flow hedges in earnings as they occur. When the hedged forecasted transaction settles and is recorded in earnings, we reclassify the related amounts from Accumulated Other Comprehensive Loss into earnings, with the result that the combination of revenue or expense from the forecasted transaction and gain or loss from the hedge are recognized in earnings at a total amount equal to the hedged price. Accordingly, the amount of derivative gains and losses recorded in Accumulated Other Comprehensive Loss and reclassified from Accumulated Other Comprehensive Loss into earnings does not reflect the total economics of the hedged forecasted transactions. The total impact of our forecasted transactions and related hedges is reflected in our Consolidated Statements of Income (Loss).

Table of Contents

        The following table presents gains and losses on derivatives designated as fair value hedges and, separately, the gains and losses on the hedged item. As discussed earlier, we record the unrealized gains and losses on fair value hedges as well as changes in the fair value of the hedged asset or liability in earnings as they occur. The difference between these amounts represents hedge ineffectiveness. Due to the sale of our Houston-based gas trading operation, we do not have any secondthird quarter activity under fair value hedges related to gas contracts.

        The following table presents gains and losses on mark-to-market derivatives, contracts that have not been designated as hedges for accounting purposes. As discussed more fully inNote 1 to our 2008 Annual Report on Form 10-K, we record the unrealized gains and losses on mark-to-market derivatives in earnings as they occur. While we use mark-to-market accounting for risk management and trading activities because changes in fair value more closely reflect the economic performance of the activity, we also use mark-to-market accounting for certain derivatives related to

portions of our physical energy delivery activities. Accordingly, the total amount of gains and losses from mark-to-market derivatives does not necessarily reflect the total economics of related transactions.

1 Other commodity contracts for the quarter ended JuneSeptember 30, 2009 include oil, freight, weather, and emission allowances. For the sixnine months ended JuneSeptember 30, 2009, other commodity contracts also include freight and uranium.

        In computing the amounts of derivative gains and losses in the above tables, we include the changes in fair values of derivative contracts up to the date of maturity or settlement of each contract. This approach facilitates a comparable presentation for both financial and physical derivative contracts. In addition, for cash flow hedges we include the impact of intra-quarter transactions (i.e., those that arise and settle within the same quarter) in both gains and losses recognized in Accumulated Other Comprehensive Loss and amounts reclassified from Accumulated Other Comprehensive Loss into earnings.

Volume of Derivative Activity

The volume of our derivatives activity is directly related to the fundamental nature and scope of our business and the risks we manage. We own or control electric generating


Table of Contents

facilities, which exposes us to both power and fuel price risk; we serve electric and gas wholesale and retail customers within our customer supply business, which exposes us to electricity and natural gas price risk; and we provide risk management services and engage in trading activities, which can expose us to a variety of commodity price risks. We conduct our business activities throughout the United States and internationally. In order to manage the risks associated with these activities, we are required to be an active participant in the energy markets, and we routinely employ derivative instruments to conduct our business.

        Derivative instruments provide an efficient and effective way to conduct our business and to manage the associated risks. We manage our generating resources and customer supply activities based upon established policies and limits, and we use derivatives to establish a portion of our hedges and to adjust the level of our hedges from time to time. Additionally, we engage in trading activities which enable us to execute hedging transactions in a cost-effective manner. We manage those activities based upon various risk measures, including position limits, economic value at risk (EVaR) and value at risk (VaR), and we use derivatives to establish and maintain those activities within the prescribed limits. We are also using derivatives to execute, control, and reduce the overall level of our trading positions and risk as well as to manage a portion of our interest rate risk associated with debt and our foreign currency risk from non-dollar denominated transactions. Accordingly, the use of derivative instruments is integral to the conduct of our business, and derivative instruments are an important tool through which we are able to manage and mitigate the risks that are inherent in our activities.

        The following table presents information designed to provide insight into the overall volume of our derivatives usage. However, the volumes presented in this table are subject to a number of limitations and should only be used as an indication of the extent of our derivatives usage and the risks they are intended to manage.

        First, the volume information is not a complete representation of our market price risk because it only includes derivative contracts. Accordingly, this table does not present a complete picture of our overall net economic exposure, and should not be interpreted as an indication of open or unhedged commodity positions, because the use of derivatives is only one of the means by which we engage in and manage the risks of our business. For example, the table does not include power or fuel quantities and risks arising from our physical assets, non-derivative contracts, and forecasted transactions that we manage using derivatives; a portion of these volumes reduce those risks. It also does not include volumes of commodities under nonderivative contracts that we use to serve customers or manage our risks. Our actual net economic exposure from our generating facilities and customer supply activities is reduced by derivatives, and the exposure from our trading activities is managed and controlled through


Table of Contents

the risk measures discussed above. Therefore, the information in the table below is only an indication of that portion of our business that we manage through derivatives and serves primarily to identify the extent of our derivatives activities and the types of risks that they are intended to manage.

        Additionally, the disclosure of derivative quantities potentially could reveal commercially valuable or otherwise competitively sensitive information that could limit the effectiveness and profitability of our business activities. Therefore, in the table below, we have computed the derivative volumes for commodities by aggregating the absolute value of net open long (purchase) and short (sell) positions within commodities for each year. This provides an indication of the level of derivatives activity, but it does not indicate either the direction of our position (long or short), or the overall size of our position. We believe this presentation gives an appropriate indication of the level of derivatives activity without unnecessarily revealing the size and direction of our derivatives positions.

        Finally, the volume information for commodity derivatives represents "delta equivalent" quantities, not gross notional amounts. We make use of different types of commodity derivative instruments such as forwards, futures, options, and swaps, and we believe that the delta equivalent quantity is the most relevant measure of the volume associated with these commodity derivatives. The delta-equivalent quantity represents a risk-adjusted notional quantity for each contract that takes into account the probability that an option will be exercised. Therefore, the volume information for commodity derivatives represents the delta equivalent quantity of those contracts, computed on the basis described above. For interest rate contracts and foreign currency contracts we have presented the notional amounts of such contracts in the table below.

1 Amounts in the table are only intended to provide an indication of the level of derivatives activity and should not be interpreted as a measure of any derivative position or overall economic exposure to market risk. Quantities are expressed as "delta equivalents" on an absolute value basis by contract type by year. Additionally, quantities relate only to derivatives and do not include potentially offsetting quantities associated with physical assets and nonderivative accrual contracts.

        In addition to the commodities in the tables above, we also hold derivative instruments related to weather and freight that are insignificant relative to the overall level of our derivative activity.

Credit-Risk Related Contingent Features

Certain of our derivative instruments contain provisions that would require additional collateral upon a credit-related event such as an adequate assurance provision or a credit rating decrease in the senior unsecured debt of Constellation Energy. The amount of collateral we could be required to post would be determined by the fair value of contracts containing such provisions that represent a net liability, after offset for the fair value of any asset contracts with the same counterparty under master netting agreements and any other collateral already posted. This collateral amount is a component of, and is not in addition to, the total collateral we could be required to post for all contracts upon a credit rating decrease.

        The following table presents information related to these derivatives. Based on contractual provisions, we estimate that if Constellation Energy's senior unsecured debt were downgraded, our total contingent collateral obligation for derivatives in a net liability position was $0.3$0.2 billion as of JuneSeptember 30, 2009, which represents the additional collateral that we could be required to post with counterparties, including both cash collateral and letters of credit, in the event of a credit downgrade to below investment grade. These amounts are associated with net derivative liabilities totaling $1.5$1.2 billion after reflecting legally binding master netting agreements and collateral already posted.

        Interpretations of SFAS No. 161 indicate thatWe present the gross fair value of derivatives in a net liability position that have credit-risk-related contingent features should be disclosed, and we present this amount in the first column in the table below. This gross fair value amount represents only the out-of-the-money contracts containing such features that are not fully collateralized by cash on a stand-alone basis. Thus, this amount does not reflect the offsetting fair value of in-the-money contracts under legally-bindinglegally-


Table of Contents

binding master netting agreements with the same counterparty, as shown in the second column in the table. These in-the-money contracts would offset the amount of any gross liability that could be required to be collateralized, and as a result, the actual potential collateral requirements would be based upon the net fair value of derivatives containing such features, not the gross amount. The amount of any possible contingent collateral for such contracts in the event of a downgrade would be further reduced to the extent that we have already posted collateral related to the net liability.

        Because the amount of any contingent collateral obligation would be based on the net fair value of all derivative contracts under each master netting agreement, we believe that the "net fair value of derivative contracts containing this feature" as shown in the table below is the most relevant measure of derivatives in a net liability position with credit-risk-related contingent features. This amount reflects the actual net liability upon which existing collateral postings are computed and upon which any additional contingent collateral obligation would be based.

2 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 we potentially could be required to post collateral.
3 Amount represents the net fair value of out-of-the-money derivative contracts containing credit-risk related contingent features after considering the mitigating effects of offsetting positions under master netting arrangements and reflects the actual net liability upon which any potential contingent collateral obligations would be based.
4 Amount includes cash collateral posted of $133.4$99.4 million and letters of credit of $882.1$691.1 million.
5 Amounts represent the additional collateral that we could be required to post with counterparties, including both cash collateral and letters of credit, in the event of a credit downgrade to below investment grade after giving consideration to offsetting derivative and non-derivative positions under master netting agreements.

Concentrations of Derivative-Related Credit Risk

Constellation Energy's wholesale and retail credit risk management policies establish the guidelines under which we extend unsecured credit to counterparties and customers. Based on the counterparty analysis and limits established by Constellation Energy, collateral or other security may be required to enter into transactions based on the potential exposure. Under most agreements we have entered into, collateral is in the form of cash or letters of credit. These forms of collateral are held by us and can be drawn upon should a counterparty default on its obligations under its agreement.

        As a best practice, we enter into commodity master agreements and cross-commodity netting agreements in order to achieve the benefits of netting in terms of exposure and collateral capital reductions. Where beneficial to the risk profile of the company, we will seek credit protections that include upfront collateral, margining, material adverse change clauses (based on credit ratings downgrades or other financial ratios events), and adequate assurances clauses in our master agreements that can be utilized to request security from our counterparties in order to cover our potential risk of loss.

        We consider a significant concentration of credit risk to be any single obligor or counterparty whose concentration exceeds 10% of total credit exposure. As of JuneSeptember 30, 2009, no single counterparty concentration comprises more than 10% of the total exposure of the portfolio, and no collection of counterparties based in a single country other than the United States comprises more than 10% of the total exposure of the portfolio.

Fair Value Measurements

SFAS No. 157,Fair Value Measurements, (SFAS No. 157) defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements. Fair value is the price that we would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).

        SFAS No. 157 also createsThe accounting requirements for fair value measurements include a fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of the fair value hierarchy are as follows:


Table of Contents

        We determine the fair value of our assets and liabilities using unadjusted quoted prices in active markets (Level 1) or pricing inputs that are observable (Level 2) whenever that information is available. We use unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available.

        We classify assets and liabilities within the fair value hierarchy based on the lowest level of input that is


Table of Contents

significant to the fair value measurement of each individual asset and liability taken as a whole. We determine fair value for assets and liabilities classified as Level 1 by multiplying the market price by the quantity of the asset or liability. We primarily determine fair value measurements classified as Level 2 or Level 3 using the income valuation approach, which involves discounting estimated cash flows using assumptions that market participants would use in pricing the asset or liability.

        We present all derivatives recorded at fair value net with the associated fair value cash collateral. This presentation of the net position reflects our credit exposure for our on-balance sheet positions but excludes the impact of any off-balance sheet positions and collateral. Examples of off-balance sheet positions and collateral include in-the-money accrual contracts for which the right of offset exists in the event of default and letters of credit. We discuss our letters of credit in more detail in theFinancing Activities section.

Recurring Measurements

BGE's assets and liabilities measured at fair value on a recurring basis are immaterial. Our merchant energy business segment's assets and liabilities measured at fair value on a recurring basis consist of the following:

        Cash equivalents represent money market mutual funds which are included in "Cash and cash equivalents" and "Nuclear decommissioning trust funds" in the Consolidated Balance Sheets. Debt and equity securities primarily represent available-for-sale investments which are included in "Nuclear decommissioning trust funds" and "Other assets" in the Consolidated Balance Sheets. Derivative instruments represent unrealized amounts related to all derivative positions, including futures, forwards, swaps, and options. We classify exchange-listed contracts as part of "Accounts Receivable" in our Consolidated Balance Sheets. We classify the remainder of our derivative contracts as "Derivative assets" or "Derivative liabilities" in our Consolidated Balance Sheets.

        The table below disaggregates our net derivative assets and liabilities on a gross contract-by-contract basis. Each individual asset or liability that is remeasured at fair value on a recurring basis is required to be presented in this table and classified, in its entirety, within the appropriate level in the fair value hierarchy. Therefore, the objective of this table is to provide information about how each individual derivative contract is valued within the fair value hierarchy, regardless of whether a particular contract is eligible for netting against other contracts or whether it has been collateralized.

        The table below sets forth by level within the fair value hierarchy the gross components of the Company's assets and liabilities that were measured at fair value on a recurring basis as of JuneSeptember 30, 2009. These gross balances are intended solely to provide information on sources of inputs to fair value and proportions of fair value involving objective versus subjective valuations and do not represent either our actual credit exposure or net economic exposure.

* We present our derivative assets and liabilities in our Consolidated Balance Sheets on a net basis. We net derivative assets and liabilities, including cash collateral, when a legally enforceable master netting agreement exists between us and the counterparty to a derivative contract. At JuneSeptember 30, 2009, we included $193.4$274.1 million of cash collateral held and $133.4$99.4 million of cash collateral posted (excluding margin posted on exchange traded derivatives) in netting amounts in the above table.

        The factors that cause changes in the gross components of the derivatives amounts in the table above are unrelated to the existence or level of actual market or credit risk from our operations. Thus, theThe gross components of the derivatives amounts in this table decreased from the corresponding amounts as of December 31, 2008, due to substantial changes in commodity prices and the decrease in the number of derivative contracts outstanding. We describe the primary factors that change the gross components below.

        SFAS No. 157 requires us to prepareWe prepared this table by separating each individual derivative contract that is in the money from each contract that is out of the money. It also requires us to ignoremoney ignoring master netting agreements and collateral for our derivatives.collateral. As a result, the gross "asset" and "liability" amounts under each of the three fair value levels far exceed our actual economic exposure to commodity price risk and credit risk. Our actual economic exposure consists of the net derivative position combined with our nonderivative accrual contracts, such as those for load-serving, and our physical assets, such as our power plants. Our actual credit risk exposure is reflected in the net derivative asset and derivative liability amounts shown in the Total Net Fair Value column.

        Increases and decreases in the gross components presented in each of the levels in this table also do not indicate changes in the level of derivative activities. Rather, the primary factors affecting the gross amounts are commodity prices and the total number of contracts. If commodity prices change, the gross amounts could increase, even if the level of contracts stays the same, because separate presentation is required for contracts that are in the money from those that are out of the money. As a result, even fully hedged positions could exhibit increases in the gross amounts if prices change. Additionally, if the number of contracts increases, the gross amounts also could increase. Thus, the execution of new contracts to reduce economic risk could actually increase the gross amounts in the table because of the required separation of contracts discussed above.

        Cash equivalents are primarily comprised of exchange traded money market funds and money market mutual funds. These instruments are valued based upon unadjusted quoted prices in active markets and are classified within Level 1. Cash equivalents classified in Level 2 are held within our nuclear decommissioning trust funds and are valued based on fund share price, which is observable on a less frequent basis.

        Debt and equity securities include trust assets securing certain executive benefits, other marketable securities, and our nuclear decommissioning trust funds. Trust assets securing certain executive benefits consist of mutual funds, which are valued based upon unadjusted quoted prices in active markets and are classified within Level 1.

active markets and are classified within Level 1. Nuclear decommissioning trust funds consist of a number of different types of securities, including the following:

        Derivative instruments include exchange-traded and bilateral contracts. Exchange-traded derivative contracts include futures and certain options. Bilateral derivative contracts include swaps, forwards, certain options and complex structured transactions. We utilize models to measure the fair value of bilateral derivative contracts. Generally, we use similar models to value similar instruments. Valuation models utilize various inputs, which include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other observable inputs for the asset or liability, and market-corroborated inputs, which are inputs derived principally from or corroborated by observable market data by correlation or other means. However, the primary input to our valuation models is the forward commodity price. We have classified derivative contracts within the fair value hierarchy as follows:

        In order to determine the fair value of derivatives, we utilize various inputs and factors including market data and assumptions that market participants would use in pricing assets or liabilities as well as assumptions about the risks inherent in the inputs to the valuation technique. The inputs and factors include:

Accounting Standards Issued

SFAS No. 167

Accounting for Variable Interest Entities

In June 2009, the FASB issued SFAS No. 167,Amendments to FASB Interpretation No. 46R, which isamended the accounting for variable interest entities, effective for interim and annual reporting periods beginning after November 15, 2009. The standard includes the following significant provisions:

        We are currently evaluating the impacts of this standard on our, and BGE's, financial results, which could be material.


SFAS No. 168Accounting Standards Adopted

In June 2009, the FASB issued SFAS No. 168,The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, which is effective for financial statements issued for interim and annual periods ending after September 15, 2009. The FASB Accounting Standards Codification (Codification) will become the sole source of authoritative generally accepted accounting principlesNoncontrolling Interests in the United States of America (GAAP) and will supersede all existing non-SEC accounting and reporting standards. Once the Codification is in effect, all of its content will carry the same level of authority, and any accounting guidance not contained within the Codification will become non-authoritative. Because the Codification is not intended to change GAAP, the adoption of this standard will not have an impact on our, or BGE's, financial results. However, our disclosures and references to accounting standards will change to reflect the new Codification structure beginning with our Form 10-Q for the quarter ending September 30, 2009.

Accounting Standards Adopted

SFAS No. 160
Consolidated Financial Statements

In December 2007, the FASB issued SFAS No. 160,Noncontrolling Interestsamended guidance related to the accounting and reporting of noncontrolling interests in Consolidated Financial Statements, an amendment of ARB No. 51. SFAS No. 160 provides that aconsolidated financial statements. A noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. This presentation is based upon the view of the consolidated business as a single economic entity and considers minority ownership interests in consolidated subsidiaries as equity in the consolidated entity.

        SFAS No. 160 requires that companies:Under the amended guidance, companies are required to:

        Effective January 1, 2009, we presented and disclosed noncontrolling interests in our Consolidated Financial Statements in accordance with SFAS No. 160.the amended guidance.

        The total changeincrease in Constellation Energy's noncontrolling interest amount of $25.8$52.4 million from December 31, 2008 to September 30, 2009 is primarily due to income earned at one entity in which we havethere is a noncontrolling interest.

        The total changeincrease in BGE's noncontrolling interest amount of $8.1$8.4 million from December 31, 2008 to September 30, 2009 is primarily due to a contribution by its noncontrolling interest owner.

SFAS No. 165

In May 2009, the FASB issued SFAS No. 165,Subsequent Events, which establishes

In May 2009, the general standards ofFASB issued a new accounting standard addressing the accounting for and disclosure of events that occur subsequent to the balance sheet date but before financial statements are issued or are available to be issued. Because this standard does not change the fundamental requirements for accounting for subsequent events, it does not have a significant impact on our, or BGE's financial results. However, this standard does require the disclosure of the date through which subsequent events have been evaluated as well as whether that date is the date the financial statements were issued. We adopted SFAS No. 165this standard as of June 30, 2009 and have provided the additional required disclosures on page 11.

Recognition and Presentation of Other-Than-Temporary Impairments, which amends

In April 2009, the FASB issued accounting guidance for the recognition and presentation of other-than-temporary impairments. This guidance amended the other-than-temporary guidance for debt securities and expandsexpanded the disclosure requirements for debt and equity securities. The available-for-sale investments in our nuclear decommissioning trust funds are managed by third parties who have independent discretion over the purchases and sales of securities. As such, the amended guidance for other-than-temporary impairments willdoes not affect our policy of recognizing impairments for any of these investments for which fair value declines below its book value. The FSPThis guidance also requires disclosures regarding available-for-sale securities in interim financial statements as well as in annual financial statements.

(Constellation Energy) is an energy company that conducts its business through various subsidiaries including a merchant energy business and Baltimore Gas and Electric Company (BGE). We describe our operating segments in theNotes to Consolidated Financial Statements beginning on page 18.19.

        This Quarterly Report on Form 10-Q is a combined report of Constellation Energy and BGE. References in this report to "we" and "our" are to Constellation Energy and its subsidiaries, collectively. References in this report to the "regulated business(es)" are to BGE. We discuss our business and strategy in more detail inItem 1—Business section of our 2008 Annual Report on Form 10-K and we discuss the risks affecting our business inItem 1A. Risk Factors section of our 2008 Annual Report on Form 10-K.

        Our 2008 Annual Report on Form 10-K includes a detailed discussion of various items impacting our business, our results of operations, and our financial condition. These include:

        Critical accounting policies are the accounting policies that are most important to the portrayal of our financial condition and results of operations and that require management's most difficult, subjective, or complex judgment. Our critical accounting policies include derivative accounting, evaluation of assets for impairment and other than temporary decline in value, and asset retirement obligations.

        In this discussion and analysis, we explain the general financial condition and the results of operations for Constellation Energy and BGE including:

        As you read this discussion and analysis, refer to our Consolidated Statements of Income (Loss) on page 3, which present the results of our operations for the quarters and sixnine months ended JuneSeptember 30, 2009 and 2008. We analyze and explain the differences between periods in the specific line items of the Consolidated Statements of Income (Loss).

        We have organized our discussion and analysis as follows:


Business Environment

Various factors affect our financial results. We discuss these various factors in theForward Looking Statements section on page 7578 and inItem 1A. Risk Factors section of our 2008 Annual Report on Form 10-K. We discuss our market risks in theRisk Management section beginning on page 70.72.

        The volatility of the financial, credit and global energy markets impacts our liquidity and collateral requirements as well as our credit risk. We discuss our liquidity and collateral requirements in theFinancial Condition section and our customer (counterparty) credit and other risks in more detail in theRisk Management section.

        In this section, we discuss in more detail events which have impacted our business during 2009.

Federal Regulation

The United States Congress and the Commodity Futures Trading Commission are evaluating additional regulations for the derivatives markets, including position limits and eliminating hedge regulatory exemptions. We are unable to determine the final form any regulations may take, but such regulations could have a material effect on our business.

Maryland PSC Review of EDF Transaction

In June 2009, during Phase I of the EDF proceeding, the Maryland Public Service Commission (Maryland PSC) determined that EDF Group and related entities (EDF) would obtain the power to exercise substantial influence over the policies and actions of BGE under Constellation Energy's proposed transaction with EDF, and, therefore, that the Maryland PSC must review the transaction to determine that it is in the public interest with benefits and no harm to consumers. EDF has filed an application with the Maryland PSC to commence the Maryland PSC's review and a decision is expected in mid-October 2009. In addition,

Environmental Matters

Air Quality

Capital Expenditures

As discussed in our 2008 Annual Report on Form 10-K, we expect to incur additional environmental capital expenditures to comply with air quality laws and regulations. Based on updated information from vendors, we expect our estimated environmental capital requirements for these air quality projects to be approximately $325$345 million in 2009, $25$10 million in 2010, $5$20 million in 2011 and $30 million from 2012-2013.

        Our estimates may change further as we implement our compliance plan. As discussed in our 2008 Annual Report on Form 10-K, our estimates of capital expenditures continue to be subject to significant uncertainties.

Global Climate Change

In September 2009, the Environmental Protection Agency proposed regulations to address greenhouse gas emissions under the Clean Air Act. The proposed regulations would require large facilities that emit at least 25,000 tons of greenhouse gases a year to obtain construction and operating permits covering these emissions. The proposed regulations would apply to many of our fossil fuel generating facilities. We are evaluating the potential impact of these regulations on our business should they be adopted. We could incur compliance costs that have a material impact on our financial results.

Accounting Standards Issued and Adopted

We discuss recently issued and adopted accounting standards in theAccounting Standards Issued andAccounting Standards Adopted sections of theNotes to Consolidated Financial Statements beginning on page 40.41.


Events of 2009

Acquisition

In July 2009, we acquired CLT Efficient Technologies Group (CLT), an energy services company. We discuss this acquisition in more detail in theNotes to Consolidated Financial Statements on page 16.


Divestitures

In January 2009, we entered into a definitive agreement to sell a majority of our international commodities operation. We completed this transaction in March 2009.

        In February 2009, we entered into a definitive agreement to sell our gas trading operation. We transferred control of this operation in April 2009. Simultaneously, we entered into an agreement with the buyer of our Houston-based gas trading operation under which that company will provide us with the gas supply needed to support our retail gas customer supply business.

        In June 2009, we completed the sale of a uranium market participant that provides marketing services to uranium producers, utilities and an investment fund in the North American and European markets.

        In August 2009, we completed the sale of our equity investment in our shipping joint venture.

        We discuss these divestitures and the gas supply agreement in more detail in theNotes to Consolidated Financial Statements beginning on page 15.16.


Merger Termination and Strategic Alternatives Costs

During the quarter and sixnine months ended JuneSeptember 30, 2009, we incurred merger termination and strategic alternatives costs related to the terminated merger with MidAmerican Energy Holdings Company (MidAmerican), the conversion of our Series A Preferred Stock, the transactions related to EDF, and other strategic alternatives costs. We discuss costs related to the mergers and strategic

alternatives in more detail on page 1112 inNotes to Consolidated Financial Statements.


Impairment Losses and Other Costs

During the quarter and sixnine months ended JuneSeptember 30, 2009, we recorded impairment losses and other costs on certain of our equity method investments, investments in equity securities and other assets. We discuss these charges in more detail in theNotes to Consolidated Financial Statements beginning on page 13.14.


Workforce Reduction Costs

During the sixnine months ended JuneSeptember 30, 2009, we incurred workforce reduction costs primarily related to the divestiture of a majority of our international commodities operation as well as some smaller restructurings elsewhere in our organization. We recognized an $11.2$11.6 million pre-tax charge in 2009 related to the elimination of approximately 180 positions. We expect all of these restructurings will be completed within 12 months from the next 12 months.program's initiation. We discuss our workforce reduction costs in more detail in theNotes to Consolidated Financial Statements beginning on page 14.15.

Merchant Energy Business

Background

Our merchant energy business is a competitive provider of energy solutions for various customers. We discuss the impact of deregulation on our merchant energy business inItem 1. Business—Competition section of our 2008 Annual Report on Form 10-K.


Table of Contents

        Our merchant energy business focuses on delivery of physical, customer-oriented products to producers and consumers, manages the risk and optimizes the value of our owned generation assets and customer supply activities, and uses our portfolio management and trading capabilities both to manage risk and to deploy risk capital.

        Earlier this year, we outlined various strategic initiatives for our Global Commodities operation. We discuss our strategy in more detail in theStrategy section of our 2008 Annual Report on Form 10-K. As of the end of the secondthird quarter of 2009, these initiatives are substantially complete, with the balance to be completed by year-end.complete.

operation, certain other trading operations, and a uranium market participant, the execution of our strategy in the future will be affected by continued uncertainty in global financial, credit, and commodities markets. Execution of our goals could have a substantial effect on the nature and mix of our business activities. In particular, upon closing the transactions contemplated by our Investment Agreement with EDF we expect thattransaction results in the deconsolidation of our subsidiary that owns our nuclear generation assets will be deconsolidated.assets. In turn, this could affect our financial position, results of operations, and cash flows in material amounts, and these amounts could vary substantially from historical results. We discuss our asset and operation divestitures in more detail in theNotes to Consolidated Financial Statements beginning on page 15.16.

        We record merchant energy revenues and expenses in our financial results in different periods depending upon which portion of our business they affect and based on the associated accounting policies. We discuss our revenue recognition policies in theCritical Accounting Policies section and inNote 1 of our 2008 Annual Report on Form 10-K.

        As part of managing our total portfolio risk, we use economic value at risk. We view economic value at risk as the most comprehensive measure of our exposure to changing commodity prices. This metric measures the risk in our total portfolio, encompassing all aspects of our merchant energy business. We also use daily value at risk and stop loss limits and liquidity guidelines to restrict the level of risk in our portfolio.

        Our Global Commodities operation actively transacts in energy and energy-related commodities in order to manage our portfolio of energy purchases and sales to customers through structured transactions. As part of these activities, we trade energy and energy-related commodities and deploy risk capital in the management of our portfolio in order to earn returns.

        We discuss the impact of our economic value at risk and value at risk in more detail in theMark-to-Market andRisk Management sections.

Revenues and Fuel and Purchased Energy Expenses

Our merchant energy business manages the revenues we realize from the sale of energy and energy-related products to our customers and our costs of procuring fuel and energy. The difference between revenues and fuel and


Table of Contents

purchased energy expenses, including all direct expenses, represents the gross margin of our merchant energy business, and this measure is a useful tool for assessing the profitability of our merchant energy business. Accordingly, we believe it is appropriate to discuss the operating results of our merchant energy business by analyzing the changes in gross margin between periods. In managing our portfolio, we may terminate, restructure, or acquire contracts primarily to reduce risk and/or improve our liquidity. Such transactions are within the normal course of managing our portfolio and may materially impact the timing of our recognition of revenues, fuel and purchased energy expenses, and cash flows.

        We discuss our merchant energy revenues, fuel and purchased energy expenses, and gross margin below.

Revenues

Our merchant energy revenues decreased $1,079.1$1,234.6 million and $1,746.6$2,981.2 million during the quarter and sixnine months ended JuneSeptember 30, 2009, respectively, compared to the same periods in 2008 primarily due to the following:

Gross Margin

We analyze our merchant energy gross margin in the following categories:

    Generation—our operation that owns, operates, and maintains fossil, nuclear, and renewable generating facilities and holds interests in qualifying facilities, and power projects in the United States and Canada. We present the gross margin results of this operation based on a 100% hedged assumption for the portfolio, related to both output from the facilities and the fuel used to generate electricity. The assumption is based on executing hedges at current market prices with the Global Commodities operation at the end of each fiscal year in order to ensure that the Generation operation is fully hedged. Therefore, all commodity price risk is managed by and presented in the results of our Global Commodities operation as discussed below. Changes in gross margin of our Generation operation during the period are due to changes in

Table of Contents

      the level of output from the generating assets, and changes in gross margin between years are a result of changes in prices and expected output.

    Customer Supply—our load-serving operation that provides energy products and services to wholesale and retail electric and natural gas customers, including distribution utilities, cooperatives, aggregators, and commercial, industrial and governmental customers. We present the gross margin results of this operation based on the gross margin value of new customer supply arrangements at the time of execution assuming an estimated level of customer usage and the impact of any changes in the underlying usage of the customers based on actual energy deliveries. Changes in estimated customer usage result from attrition (customers changing suppliers) or variable load risk (changes in actual usage when compared to expected usage). All commodity price risk is presented in and managed by our Global Commodities operation as discussed below.
    Global Commodities—our marketing, risk management, and trading operation that manages contractually owned physical assets, including generation facilities, natural gas properties, provides risk management services, and trades energy and energy-related commodities. This operation provides the wholesale risk management function for our Generation and Customer Supply operations, as well as our structured products and energy investments portfolios, and includes our merchant energy business' actual hedged positions with third parties. Therefore, changes in gross margin for this operation result mostly from changes in commodity prices and positions across the various commodities and regions in which we transact.

    Generation

    The $111$22 million increase in Generation gross margin during the quarter ended JuneSeptember 30, 2009 compared to the same period of 2008 is primarily due to an increase of $29 million due to the timing and duration of planned and unplanned outages at our nuclear and fossil generating assets, partially offset by a $7 million decrease from lower energy prices on hedged gross margin with Global Commodities for the output of our generating assets in the PJM and New York regions based on prices established at the end of 2008 (see Global Commodities discussion below for impact of prices during 2009).

            The $167 million increase in generation gross margin during the nine months ended September 30, 2009 compared to the same period of 2008 is primarily due to the following:

      $58109 million due to the timing and duration of planned and unplanned outages at our nuclear and fossil generating plants, and
      $84 million increase from higher energy prices on hedged gross margin with Global Commodities for the output of our generating assets in the PJM and New York regions based on prices established at the end of 2008 (see Global Commodities discussion below for impact of prices during 2009), and
      $53 million due to the timing and duration of planned and unplanned outages at our nuclear and fossil generating plants.

            The $145 million increase in generation gross margin during the six months ended June 30, 2009 compared to the same period of 2008 is primarily due to the following:

      $93 million increase from higher energy prices on hedged gross margin with Global Commodities for the output of our generating assets in the PJM and New York regions based on prices established at the end of 2008 (see Global Commodities discussion below for impact of prices during 2009), and
      $78 million due to the timing and duration of planned and unplanned outages at our nuclear and fossil generating plants..

            These increases were partially offset by $26 million of lower gross margin primarily related to our investmentinvestments in power projects.

    Customer Supply

    The $40$2 million decrease in Customer Supply gross margin during the quarter ended JuneSeptember 30, 2009 compared to the same period of 2008 is primarily due to the following:

      $68 million related to lower realization of contracts executed in prior periods and lower new business originated and realized during the quarter primarily in our wholesale and retail power supply operations, and
      $21$71 million of higher costs due tolower gross margin as a result of lower customer retention and unfavorable variable load risk associated with

        wholesale and retail power primarily due to variances from normal weather and lower demand during the quarter ended JuneSeptember 30, 2009.

            These decreases wereThis decrease was partially offset by the following:

      $2545 million of higher gross margin related to the consolidation of a retail power supply variable interest entity (VIE) for which we became the primary beneficiary in December 2008, and
      $2414 million of higher mark-to-market results primarily in our retail gas operation. We discuss these results in more detail in theMark-to-Market section beginning on page 51.53, and
      $10 million related to higher realization of contracts executed in prior periods and higher margins on new business originated and realized during the quarter primarily in our wholesale and retail power supply operations, partially offset by lower volumes.

            The $30$28 million increase in customer supply gross margin during the sixnine months ended JuneSeptember 30, 2009 compared to the same period of 2008 is primarily due to:

      $4388 million of higher gross margin mostly related to the consolidation of a retail power supply VIE for which we became the primary beneficiary in December 2008, and
      $910 million related to higher realization of contracts executed in prior periods and higher margins on new business originated and realized during the nine months ended September 30, 2009 primarily in our wholesale and retail power supply operations, partially offset by lower volumes.

            These increases were partially offset by the following:

      $62 million of lower costs due to highergross margin as a result of lower customer retention and from managingunfavorable variable load risk associated with wholesale and retail power primarily due to less extremevariances from normal weather during the quarter ended March 31, 2009.and lower demand, and

            These increases were partially offset by $22Table of Contents

            During the quarter and sixnine months ended JuneSeptember 30, 2009, the higher margin related to the consolidated retail power supply VIE is fully attributable to noncontrolling interests.

    Global Commodities

    We present Global Commodities results in the following categories:

            Our portfolio de-risking and liquidity improving activities had a substantial impact on the comparability of results for the quarter and nine months ended September 30, 2009 as discussed below.

    The $243$320 million decreaseincrease in gross margin from our Global Commodities activities during the quarter ended JuneSeptember 30, 2009 compared to the same period of 2008 is primarily due to:

            We did not record any origination gains during the sixnine months ended JuneSeptember 30, 2009. During the sixnine months ended JuneSeptember 30, 2008, our Global Commodities operation amended certain nonderivative contracts to mitigate counterparty performance risk under the existing contracts. As a result of these amendments, the revised contracts became derivatives subject to mark-to-market accounting. The change in accounting for these contracts from

            As discussed in theCritical Accounting Policies section of our 2008 Annual Report on Form 10-K, our "Derivative assets and liabilities" include contracts accounted for as hedges and those accounted for on a mark-to-market basis. These amounts are presented in our Consolidated Balance Sheets after the impact of legally binding master netting agreements. Due to the impacts of commodity prices, the number of open positions, master netting arrangements, and offsetting risk positions on the presentation of our derivative assets and liabilities in our Consolidated Balance Sheets, we believe an evaluation of the net position is the most relevant measure, and is discussed in more detail below.

            The decrease in our net derivative liability subject to hedge accounting since December 31, 2008 of $669.7$986.3 million was due primarily to $1,212$1,338 million of realization of out-of-the-money cash-flow hedges, partially offset by $542$352 million of increases on our out-of-the-money cash-flow hedge positions primarily related to decreases in power, natural gas, and coal prices during the sixnine months ended JuneSeptember 30, 2009.

    Cash Flows from Investing Activities

    Cash used in investing activities was $1,898.0$2,391.2 million in 2009 compared to $1,167.6$1,424.3 million in 2008. The $730.4$966.9 million increase in cash used in 2009 compared to 2008 was primarily due to $2,153.7 million for contract and portfolio acquisitions.acquisitions as a component of our strategic divestitures. As a result of the structure of the divestitures of a majority of our international commodities, Houston-based gas trading and other trading operations, we are required to present investing cash outflows for in-the-money contracts on a gross basis separate from financing cash inflows for out-of-the-money contracts executed simultaneously. We discuss our divestitures in more detail beginning on page 1516 of theNotes to Consolidated Financial Statements. There was no such activity in 2008.

    Security Ratings

    We discuss our security ratings in our 2008 Annual Report on Form 10-K.

            On July 31, 2009, Fitch Ratings downgraded Constellation Energy's senior unsecured debt rating from BBB to BBB- andBBB-and BGE's senior unsecured debt rating from A- to BBB+. Fitch Ratings also updated both companies' ratings outlook from Watch Evolving to Stable.

            On August 19, 2009, Moody's Investor Service reaffirmed Constellation Energy's senior unsecured debt rating of Baa3 and issued a Stable ratings outlook.

            On November 2, 2009, S&P downgraded Constellation Energy's senior unsecured debt rating to BBB- with a Stable outlook from BBB on Watch Negative. As a result of this rating action, we were not required to post any additional collateral pursuant to our counterparty agreements. In addition, BGE's senior unsecured debt rating was upgraded to BBB+ with a Stable outlook from BBB on Watch Negative.


    Available Sources of Funding

    In addition to cash generated from business operations, we rely upon access to capital for our capital expenditure programs and for the liquidity required to operate and support our commercial businesses. Our liquidity requirements are funded by credit facilities and cash. We fund our short-term working capital needs with existing cash and with our credit facilities, many of which support direct cash borrowings and the issuance of commercial paper. We also use our credit facilities to support the issuance of letters of credit, primarily for our merchant energy business.

            The primary drivers of our use of liquidity have been our capital expenditure requirements and collateral requirements associated with hedging our generating assets and hedging our Customer Supply business in both power and gas. As part of our strategic initiatives, we have modified the structure of certain transactions and terminated others in order to reduce these collateral requirements. Significant changes in the prices of commodities, depending on hedging strategies we have employed, could require us to post additional letters of credit, and thereby reduce the overall amount available under our credit facilities or to post additional cash, and thereby reduce our available cash balance.

    Constellation Energy

    At JuneSeptember 30, 2009, we had approximately $5.6$5.8 billion in committed credit facilities available as shown below. We have also included in the table below the pro forma effect on our credit facilities as of

    2 Excludes commodity-linked credit facility discussed below due to its contingent nature.

            Collectively, these facilities currently support the issuance of letters of credit and/or cash borrowings up to approximately $5.6$5.8 billion as of JuneSeptember 30, 2009. At JuneSeptember 30, 2009, we had approximately $2.8$2.0 billion in letters of credit issued, and we had no commercial paper outstanding.

            During the third quarter of 2009, we executed a new committed five year bilateral credit facility that allows for a maximum capacity of $500 million. This facility can be used to issue letters of credit in support of our collateral obligations. At September 30, 2009 and November 3, 2009, we had committed capacity of $250 million and $500 million, respectively. The facility partially replaces a portion of our credit facilities that terminate upon closing of the transaction with EDF.

            During the third quarter of 2009, we also entered into a five year commodity-linked credit facility that allows for the issuance of letters of credit up to a maximum capacity of $500 million. We could increase the maximum facility size to $750 million or alternatively enter into an additional $250 million bilateral facility if certain conditions are met, including the closing of the transaction with EDF. This commodity-linked facility is designed to help manage our contingent collateral requirements associated with the hedging of our Customer Supply operations because its capacity increases as natural gas price levels decrease compared to a reference price that is adjusted periodically. As of September 30, 2009, there were no letters of credit outstanding under this facility.

            In connection with the Investment Agreement with EDF, EDF has provided us with up to $2 billion pre-tax, or approximately $1.4 billion after-tax, of additional liquidity pursuant to a put arrangement that will allow us to require EDF to purchase certain non-nuclear generation assets. The amount of after-tax proceeds will be impacted by the assets actually sold and the related tax impacts at that time.

            During April 2009, we received regulatory approvals and consents for the majority of the assets covered by the put arrangement. As of July 31,September 30, 2009, we have approximately $1.1 billion after-tax of liquidity available under the put arrangement. We expect to receive regulatory approval for an additional asset in the first quarter of 2010, which will increase the net after-tax liquidity from the put arrangement to approximately $1.4 billion. The put arrangement will expire at the earlier of December 31, 2010 or the termination of the Investment Agreement by EDF in the event of a breach of contract by us.

            Certain credit facilities of Constellation Energy contain a provision requiring Constellation Energy to maintain a ratio of debt to capitalization equal to or less than 65%. At JuneSeptember 30, 2009, the debt to capitalization ratios as defined in the credit agreements were no greater than 51%46%.

            Our $1.23 billion credit facility requires us to maintain consolidated earnings before interest, taxes, depreciation, and amortization to consolidated interest expense ratio of at least 2.75 when our Standard and Poors (S&P) senior unsecured debt rating is BBB- or lower and our Moody's senior unsecured debt rating is Baa3 or lower. Compliance with the covenant iswas not required as of July 31,September 30, 2009 as S&P's senior unsecured debt rating iswas above BBB-. Since the $1.23 billion credit facility expires upon the earlier of the closing of the EDF transaction or November 12, 2009, the recent change in rating by S&P to BBB- will not require compliance with this covenant.

            The terms of the Series B Preferred Stock allow us to issue debt without the consent of the holders of the majority of the Series B Preferred Stock only if, after issuance of such debt, we maintain a ratio of debt to capitalization equal to or less than 65%. Upon closing of our transaction with EDF, the Series B Preferred Stock will be redeemed.

    BGE

    As of September 30, 2009, BGE currently maintainshas a $400.0 million five-year revolving credit facility expiring in 2011. BGE can use the facility to issue letters of credit or to issue short-term debt through the issuance of commercial paper or through direct borrowing against the facility. On October 29, 2009, BGE expanded its borrowing capacity to

    $575 million. The size of the facility may be increased up to $600 million with additional commitments by lenders. At JuneSeptember 30, 2009, BGE had $0.5$334.9 million outstanding on its $400 million credit facility to secure funds in advance of maturing commercial paper and other obligations.

            At June 30, 2009, BGE had $339.9 million in commercial paper outstanding.

            The credit agreement of BGE contains a provision requiring BGE to maintain a ratio of debt to capitalization equal to or less than 65%. At JuneSeptember 30, 2009, the debt to capitalization ratio for BGE as defined in this credit agreement was 52%.

    Constellation Energy and BGE

    Decreases in Constellation Energy's or BGE's credit ratings would not trigger an early payment on any of our, or BGE's, credit facilities.

            However, the impact of a credit ratings downgrade on our financial ratios associated with our credit facility covenants would depend on our financial condition at the time of such a downgrade and on the source of funds used to satisfy the incremental collateral obligation resulting from a credit ratings downgrade. For example, if we were to use existing cash balances or exercise the put option with EDF to fund the cash portion of any additional collateral obligations resulting from a credit ratings downgrade, we would not expect a material impact on our financial ratios. However, if we were to issue long-term debt or use our credit facilities to fund any additional collateral obligations, our financial ratios could be materially affected. Failure by Constellation Energy, or BGE, to comply with these covenants could result in the acceleration of the maturity of the borrowings outstanding and preclude us from issuing letters of credit under these facilities.

            Through our efforts to reduce risk, we have significantly improved our liquidity. Specifically, we executed on our planned divestitures, significantly reduced the activities of our Global Commodities operation, and restructured and terminated existing transactions and amended certain agreements, all of which have led to lower collateral requirements. Through JuneSeptember 30, 2009, we received substantially all of the $1 billion of total net collateral expected to be returned as a result of the successful execution of our divestitures. The change in credit facilities and EDF put arrangement was due to the receipt of required regulatory approvals on the majority of assets covered by the EDF put arrangement, which resulted in the termination of the EDF interim backstop liquidity facility. Finally, cash flows from operating activities funded the repayment of all outstanding cash draws on our credit facilities, and BGE was able to issue $339.9$334.9 million of commercial paper, demonstrating an ability to access the capital market in a more traditional manner.

            Upon the close of the EDF transaction, the amount and composition of our liquidity will change due to the reduction in credit facilities discussed on page 67, as well as the receipt of net cash proceeds from the transaction.

            The net proceeds from this transaction are expected to be approximately $2.2 billion after repayment of the EDF preferred stock and the payment of taxes. We anticipate using these proceeds to reduce up to $850 million of our long-term debt, as well as for other general corporate purposes, including payments related to BGE under the Maryland PSC order dated October 30, 2009. These net proceeds will partially offset the reduction in credit facilities, although our net available liquidity will be reduced.

            Our liquidity needs vary as commodity prices change. We regularly evaluate the effects of changing price levels on our liquidity needs by estimating the impacts of volatile power, gas, and coal prices on our price sensitive sources and uses of liquidity. For example, energy contracts settling in the current year may impact our cash flows and changing price levels may impact our collateral requirements. Additionally, we consider the impact of other sources and uses of liquidity, including planned business divestitures, anticipated new business, capital expenditures, operating expenses and credit charges.

            We believe that the actions that we have taken and our current net available liquidity will be sufficient to support the ongoing liquidity requirements over the next 12 months. Our liquidity projections include assumptions for commodity price changes, which are subject to significant volatility, and we are exposed to certain operational risks that could have a significant impact on our liquidity. We discuss significant items that could negatively impact our liquidity in theRisk Factors section of our 2008 Annual Report on Form 10-K.


    Collateral

    Constellation Energy's collateral requirements arise from its merchant energy business' need to participate in certain organized markets, such as Independent System Operators (ISOs) or financial exchanges, as well as from our margining on over-the-counter (OTC) contracts.

            To support wholesale and retail power Customer Supply obligations, as well as some trading activities, Constellation Energy posts collateral to ISOs. Forward hedging of our Generation and Customer Supply obligations, as well as our Global Commodities trading activities, creates the need to transact with exchanges such as New York Mercantile Exchange and Intercontinental Exchange. We post initial margin based on exchange rules, as well as variation margin related to the change in value of the net open position with the exchange. Constellation Energy's initial margin requirements increased during the third quarter of 2008 as a result of changes in exchange rules and decreased during the fourth quarter of 2008 as a result of portfolio risk reduction and downsizing activities.

            During the sixnine months ended JuneSeptember 30, 2009, our initial margin requirements continued to decrease. In March 2009 and April 2009, we closed out our exchange positions related to our international commodities operation and Houston-based gas trading operation, respectively, which reduced our margin posted with each exchange with which we transact. Daily variation margin postings to each exchange depend on price moves in the underlying power, gas and coal exchange traded forward and option contracts.

            In addition to the collateral posted to ISOs and exchanges, we post collateral with certain OTC counterparties. These collateral amounts may be fixed or may vary with price levels.

            There are certain asymmetries relating to the use of collateral that create liquidity requirements for our merchant energy businesses. These asymmetries arise as a result of our actions to be economically hedged, as well as market conditions or conventions for conducting business


    Table of Contents

    that result in some transactions being collateralized while others are not, including:


    Table of Contents

            Customers of our merchant energy business rely on the creditworthiness of Constellation Energy. In this regard, we have certain agreements that contain provisions that would require us to post additional collateral upon a credit rating downgrade in the senior unsecured debt of Constellation Energy. Based on contractual provisions at JuneSeptember 30, 2009, we estimate that if Constellation Energy's senior unsecured debt were downgraded to one level below the investment grade threshold we would have the following additional collateral obligations:

    ** Includes $0.3$0.2 billion related to derivative contracts as discussed in Notes to Consolidated Financial Statements beginning on page 35.36.

            Based on market conditions and contractual obligations at the time of a downgrade, we could be required to post additional collateral in an amount that could exceed the obligation amounts specified above, which could be material. We discuss our credit facilities in theAvailable Sources of Funding section.


    Capital Resources

    Our estimated annual cash requirement amounts for the years 2009 and 2010 are shown in the table below.

            We will continue to have cash requirements for:

            Capital requirements for 2009 and 2010 include estimates of spending for existing and anticipated projects. We continuously review and modify those estimates. Actual requirements may vary from the estimates included in the table below because of a number of factors including:

    Capital Requirements

    Merchant Energy Business

    Our merchant energy business' capital requirements consist of its continuing requirements, including expenditures for:

    Cost for Decommissioning Nuclear Facilities

    Every two years, the U. S. Nuclear Regulatory Commission (NRC) requires us to demonstrate reasonable assurance that funds will be available to decommission our nuclear generating facilities after these facilities cease operation. In response to our March 2009 biennial report, the NRC notified us that they had identified a potential "shortfall" in


    Table of Contents

    the decommissioning fund balance for certain of our nuclear reactors. This condition was a result of declining market performance during the last two quarters of 2008 for the investments held by our decommissioning trusts.

            In July 2009, we filed withsubmitted to the NRC a plan that we expect will enable us to demonstrate by December 2009 reasonable assurance for adequate decommissioning funding in accordance with NRC regulations. Our plan proposes the use of a safe storage approach which allows funds to grow during the extended safe storage period following license termination but prior to decommissioning. In the event the NRC requires additional funding assurance beyond consideration of the safe storage approach, we will provide parental guarantees which would be subject to review and updating as necessary, but which are expected to be less than $70 million in the aggregate as of December 2009. We discuss the costs for decommissioning our nuclear generating facilities in more detail in theBusiness Overview section of our 2008 Annual Report on Form 10-K.

    Regulated Electric and Gas

    Regulated electric and gas construction expenditures primarily include new business construction needs and improvements to existing facilities, including projects to improve reliability and support demand response and conservation initiatives.

            In July 2009, BGE filed with the Maryland PSC a proposal for a comprehensive and advanced smart grid initiative. The proposal includes the planned installation of 2 million residential and commercial electric and gas smart meters. We expect the total cost of the program to be approximately $480 million, although potential stimulus funding frommillion. In October 2009, the United States Department of Energy could reduceselected BGE as a recipient of $200 million in federal funding for our smart grid initiative. This grant allows BGE to be reimbursed for smart grid expenditures up to $200 million, substantially reducing the total cost by as much as $200 million.of this initiative. However, the United States Department of Energy may withhold funding until approval is obtained from the Maryland PSC. If approved by the Maryland PSC, BGE plans to proceed with this proposal would have a material impact on future regulated electric and gas construction expenditures.as soon as practical.


    Funding for Capital Requirements

    We discuss our funding for capital requirements in our 2008 Annual Report on Form 10-K.


    Contractual Payment Obligations and Committed Amounts

    We enter into various agreements that result in contractual payment obligations in connection with our business activities. These obligations primarily relate to our financing arrangements (such as long-term debt, preference stock, and operating leases), purchases of capacity and energy to support the growth in our merchant energy business activities, and purchases of fuel and transportation to satisfy the fuel requirements of our power generating facilities.

    Off-Balance Sheet Arrangements

    We discuss our off-balance sheet arrangements in our 2008 Annual Report on Form 10-K.

            At JuneSeptember 30, 2009, Constellation Energy had a total face amount of $14.1$11.9 billion in guarantees outstanding, of which $12.7$10.5 billion related to our merchant energy business. These amounts do not represent incremental consolidated Constellation Energy obligations; rather, they primarily represent parental guarantees of certain subsidiary obligations to third parties in order to allow our subsidiaries the flexibility needed to conduct business with counterparties without having to post other forms of collateral. Our estimated net exposure for obligations under commercial transactions covered by these guarantees was approximately $2.5$2 billion at JuneSeptember 30, 2009, which represents the total amount the parent company could be required to fund based on JuneSeptember 30, 2009 market prices. For those guarantees related to our derivative liabilities, the fair value of the obligation is recorded in our Consolidated Balance Sheets. We believe it is unlikely that we would be required to perform or incur any losses associated with guarantees of our subsidiaries' obligations.

            We discuss our other guarantees in theNotes to Consolidated Financial Statements beginning on page 23.25.

    Risk Management

    Market Risk

    Economic Value at Risk (EVaR)

    EVaR is a measure that attempts to estimate the sensitivity of our total portfolio economic value to changes in market prices. The EVaR measure includes all positions of our merchant energy business, including Generation, Customer Supply, and Global Commodities operations. Each business day, the Company undertakes EVaR calculations that include both its trading and its non-trading risks. EVaR for non-trading positions measures the amount of potential change in the fair values of the exposures related to accrual exposures. EVaR is a one-day measure calculated at a 95% confidence level on the portfolio through 2013. At JuneSeptember 30, 2009, our EVaR was approximately $97$67 million, which represents a 29%50% decline from its level of $136 million at December 31, 2008.

            Due to the inherent limitations of statistical measures such as EVaR and the seasonality of changes in market prices, the EVaR calculation may not reflect the full extent of our commodity price risk exposure. Additionally, because our EVaR methodology uses a linear approximation method, actual changes in the value of options in our portfolio resulting from significant price changes may differ from estimates generated using this methodology. As a result, actual changes in the fair value of derivative assets and liabilities subject to mark-to-market accounting could differ from the calculated EVaR, and such changes could have a material impact on our financial results.


    Table of Contents

            While EVaR reflects the risk of loss under normal market conditions, stress testing captures Constellation Energy's exposure to unlikely but plausible events in abnormal markets. We regularly conduct economic value stress tests for our market activities using multiple scenarios that assume stressed changes in both price level and spreads. Additional scenarios focus on the risks predominant in individual portions of our business segments and include scenarios that focus on loss of generation, customer demand growth or demand destruction, or a shift in the composition of load serving customers.

            Along with EVaR, stress testing is important in measuring and controlling risk. Stress testing enhances the understanding of Constellation Energy's risk profile and loss potential, and stress losses are monitored against limits. We also use stress testing in approvals of non-standard transactions and for cross-business risk measurement, as well as an input to economic capital allocation. Stress test results, trends, and explanations are provided each month to Constellation Energy's senior management and to the lines of business to help them better measure and manage risks and to understand event risk-sensitive positions.

    Value at Risk (VaR)

    Where EVaR is a measure that attempts to estimate the sensitivity of our total portfolio economic value, VaR is a measure that attempts to measureestimates the sensitivity of our mark-to-market energy contracts of our Global Commodities operation to potential changes in market prices. VaR is a statistical model designed to predict risk of loss based on historical market price volatility. We calculate VaR using a historical variance/covariance technique that models option positions using a linear approximation of their value. Additionally, we estimate variances and correlation using historical commodity price changes over the most recent rolling three-month period. Our VaR calculation includes all of our Global Commodities operation derivative assets and liabilities subject to mark-to-market accounting, including contracts for energy commodities and derivatives that result in physical settlement and contracts that require cash settlement. VaR is a statistical risk measurement model subject to limitations similar to those of EVaR.

            The VaR calculation does not include market risks associated with activities that are subject to accrual accounting, primarily our generating facilities and our customer supply load-serving activities.

            The VaR amounts below represent the potential pre-tax loss in the fair value of our Global Commodities operation derivative assets and liabilities subject to mark-to-market accounting, including both trading and

These activities continue to be managed with daily VaR limits, stop loss limits and liquidity guidelines and are immaterial relative to the overall portfolio VaR.

    Credit Risk

    We measure wholesale credit risk as the replacement cost for open energy commodity and derivative transactions (both mark-to-market and accrual) adjusted for amounts owed to or due from counterparties for settled transactions. The replacement cost of open positions represents unrealized gains, net of any unrealized losses, where we have a legally enforceable right of setoff. We monitor and manage the credit risk of our Global Commodities operation through credit policies and procedures, which include an established credit approval process, daily monitoring of counterparty credit limits, the use of credit mitigation measures such as margin, collateral, or prepayment arrangements, and the use of master netting agreements.

    1 Includes counterparties with an investment grade rating by at least one of the major credit rating agencies. If split rating exists, the lower rating is used.

            Our exposure to "Not Rated" counterparties was $1$0.9 billion at JuneSeptember 30, 2009 compared to $1.5 billion at December 31, 2008. This decrease was mostly due to a decrease in our portfolio's credit exposure to natural gas customers, international coal customers, and freight companies that do not have public credit ratings as a result of the divestiture of a majority of our international commodities operation.

            Many of our not rated counterparties are considered investment grade equivalent based on our internal credit ratings. We utilize internal credit ratings to evaluate the creditworthiness of our wholesale customers, including those companies that do not have public credit ratings. Based on internal credit ratings, approximately $528.5$535 million or 52%61% of the exposure to not rated counterparties was rated investment grade equivalent at JuneSeptember 30, 2009 and approximately $883.7 million or 60% was rated investment grade equivalent at December 31, 2008.

            Our total exposure, net of collateral, to counterparties across our entire wholesale portfolio is $3$2.5 billion as of JuneSeptember 30, 2009. The top ten counterparties account for 37%39% of our total exposure. As shown in the table below, no single counterparty concentration comprises more than 10% of the total exposure of the portfolio.

            If a counterparty were to default on its contractual obligations and we were to liquidate transactions with that entity, our potential credit loss would include all forward and settlement exposure plus any additional costs related to termination and replacement of the positions. This would include contracts accounted for using the mark-to-market, hedge, and accrual accounting methods, the amount owed or due from settled transactions, less any collateral held from the counterparty. In addition, if a counterparty were to default under an accrual contract that is currently favorable to us, we may recognize a material adverse impact on our results in the future delivery period to the extent that we are required to replace the contract that is in default with another contract at current market prices. To reduce our credit risk with counterparties, we attempt to enter into agreements that allow us to obtain collateral on a contingent basis, seek third-party guarantees of the counterparty's obligation, and enter into netting agreements that allow us to offset receivables and payables with forward exposure across many transactions.

            Our total exposure of $3$2.5 billion, net of collateral, includes accrual positions and derivatives. The portion of our wholesale credit risk related to transactions that are recorded in our Consolidated Balance Sheets, net of collateral, totals approximately $1$0.9 billion and primarily relates to open energy commodity positions from our Global Commodities operation that are accounted for using mark-to-market accounting, derivatives that qualify for designation as hedges, as well as amounts owed by wholesale counterparties for transactions that settled but have not yet been paid.

            Due to volatility in the prices of energy commodities and derivatives, the market value of contractual positions with individual counterparties could exceed established credit limits or collateral provided by those counterparties. If such a counterparty were then to fail to perform its obligations under its contract (for example, fail to deliver the power our Global Commodities operation had contracted for), we could incur a loss that could have a material impact on our financial results.

            If a counterparty were to default and we were to liquidate all contracts with that entity, our credit loss would include the loss in value of derivative contracts recorded at fair value, the amount owed for settled transactions, and additional payments, if any, that we would have to make to settle unrealized losses on accrual contracts. In addition, if a counterparty were to default under an accrual contract that is currently favorable to us, we may recognize a material adverse impact in our results in the future delivery period to the extent that we are required to replace the contract that is in default with another contract at current market prices. These potential losses would be limited to the extent that the in-the-money amount exceeded any credit mitigants such as cash, letters of credit, or parental guarantees supporting the counterparty obligation.

            We also enter into various wholesale transactions through Independent System Operators (ISOs). These ISOs are exposed to counterparty credit risks. Any losses relating to counterparty defaults impacting the ISOs are allocated to and borne by all other market participants in the ISO. These ISOs have established credit policies and practices to mitigate the exposure of counterparty credit risks. As a market participant, we continuously assess our exposure to the credit risks of each ISO.

            BGE is exposed to wholesale credit risk of its suppliers for electricity and gas to serve its retail customers. BGE may receive performance assurance collateral to mitigate electricity suppliers' credit risks in certain circumstances. Performance assurance collateral is designed to protect BGE's potential exposure over the term of the supply contracts and will fluctuate to reflect changes in market prices. In addition to the collateral provisions, there are supplier "step-up" provisions, where other suppliers can step in if the early termination of a full-requirements service agreement with a supplier should occur, as well as specific mechanisms for BGE to otherwise replace defaulted supplier contracts. All costs incurred by BGE to replace the supply contract are to be recovered from the defaulting supplier or from customers through rates.

    Items 4 and 4(T). Controls and Procedures

    A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Constellation Energy or BGE have been detected. These inherent limitations include errors by personnel in executing controls due to faulty judgment or simple mistakes, which could occur in situations such as when personnel performing controls are new to a job function or when inadequate resources are applied to a process. Additionally, controls can be circumvented by the individual acts of some persons or by collusion of two or more people.

            The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no absolute assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions or personnel, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

    Evaluation of Disclosure Controls and Procedures

    The principal executive officersofficer and principal financial officersofficer of both Constellation Energy and BGE have each evaluated the effectiveness of the disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the fiscal quarter covered by this quarterly report (the "Evaluation Date"). Based on such evaluation, such officers have concluded that, as of the Evaluation Date, Constellation Energy's disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed in the reports that Constellation Energy files and submits under the Exchange Act is recorded, processed, summarized, and reported when required and is accumulated and communicated to management, as appropriate, to allow timely decisions regarding required disclosure.

    Changes in Internal Control over Financial Reporting

    During the quarter ended JuneSeptember 30, 2009, there has been no change in either Constellation Energy's or BGE's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, either Constellation Energy's or BGE's internal control over financial reporting.

    Forward Looking Statements

    We make statements in this report that are considered forward looking statements within the meaning of the Securities Exchange Act of 1934. Sometimes these statements will contain words such as "believes," "anticipates," "expects," "intends," "plans," and other similar words. We also disclose non-historical information that represents management's expectations, which are based on numerous assumptions. These statements and projections are not guarantees of our future performance and are subject to risks, uncertainties, and other important factors that could cause our actual performance or achievements to be materially different from those we project. These risks, uncertainties, and factors include, but are not limited to:

      the timing and extent of changes in commodity prices and volatilities for energy and energy related products including coal, natural gas, oil, electricity, nuclear fuel, freight, and emission allowances, and the impact of such changes on our liquidity requirements,
      the liquidity and competitiveness of wholesale markets for energy commodities,
      the conditions of the capital markets, interest rates, foreign exchange rates, availability of credit facilities to support business requirements, liquidity, and general economic conditions, as well as Constellation Energy Group's (Constellation Energy) and Baltimore Gas and Electric's (BGE) ability to maintain their current credit ratings,
      the effectiveness of Constellation Energy's and BGE's risk management policies and procedures and the ability and willingness of our counterparties to satisfy their financial and performance commitments,
      the ability to complete our strategic initiatives to improve our liquidity and the impact of such initiatives on our business and financial results,
      losses on the sale or write-down of assets due to impairment events or changes in management intent with regard to either holding or selling certain assets,
      the ability to successfully identify, finance, and complete acquisitions and sales of businesses and assets,
      the likelihood and timing of the completion of the pending transaction with EDF Group and related entities (EDF), the terms and conditions of any required regulatory approvals for the pending transaction, potential impact of a termination of the pending transaction and potential diversion of management's time and attention from our ongoing business during this time period,
      the effect of weather and general economic and business conditions on energy supply, demand, prices, and customers' and counterparties' ability to perform their obligations or make payments,
      the ability to attract and retain customers in our Customer Supply activities and to adequately forecast their energy usage,
      the timing and extent of deregulation of, and competition in, the energy markets, and the rules and regulations adopted in those markets,
      uncertainties associated with estimating natural gas reserves, developing properties, and extracting natural gas,
      regulatory or legislative developments federally, in Maryland, or in other states that affect deregulation, the price of energy, transmission or distribution rates and revenues, demand for energy, or increases in costs, including costs related to nuclear power plants, safety, or environmental compliance,
      the ability of our regulated and nonregulated businesses to comply with complex and/or changing market rules and regulations,
      the ability of BGE to recover all its costs associated with providing customers service,
      operational factors affecting commercial operations of our generating facilities (including nuclear facilities) and BGE's transmission and distribution facilities, including catastrophic weather-related damages, unscheduled outages or repairs, unanticipated changes in fuel costs or availability, unavailability of coal or gas transportation or electric transmission services, workforce issues, terrorism, liabilities associated with catastrophic events, and other events beyond our control,
      the actual outcome of uncertainties associated with assumptions and estimates using judgment when applying critical accounting policies and preparing financial statements, including factors that are estimated in determining the fair value of energy contracts, such as the ability to obtain market prices and, in the absence of verifiable market prices, the appropriateness of models and model inputs (including, but not limited to, estimated contractual load obligations, unit availability, forward commodity prices, interest rates, correlation and volatility factors),
      changes in accounting principles or practices, and
      cost and other effects of legal and administrative proceedings that may not be covered by insurance, including environmental liabilities.

            Given these uncertainties, you should not place undue reliance on these forward looking statements. Please see the other sections of this report and our other periodic reports filed with the Securities and Exchange Commission (SEC) for more information on these factors. These forward looking statements represent our estimates and assumptions only as of the date of this report.

            Changes may occur after that date, and neither Constellation Energy nor BGE assumes responsibility to update these forward looking statements.
