COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Nature of Operations

Dominion, headquartered in Richmond, Virginia, is one of the nation’s largest producers and transporters of energy. Dominion’s operations are conducted through various subsidiaries, including Virginia Power, a regulated public utility that generates, transmits and distributes electricity for sale in Virginia and northeastern North Carolina.

Note 2. Significant Accounting Policies

As permitted by the rules and regulations of the SEC, Dominion’s and Virginia Power’s accompanying unaudited Consolidated Financial Statements contain certain condensed financial information and exclude certain footnote disclosures normally included in annual audited consolidated financial statements prepared in accordance with GAAP. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

In Dominion’s and Virginia Power’s opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position as of March 31, 2013, and their results of operations and cash flows for the three months ended March 31, 2013 and 2012. Such adjustments are normal and recurring in nature unless otherwise noted.

The Companies make certain estimates and assumptions in preparing their Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from those estimates.

Dominion’s and Virginia Power’s accompanying unaudited Consolidated Financial Statements include, after eliminating intercompany transactions and balances, their accounts and those of their respective majority-owned subsidiaries and those VIEs where Dominion has been determined to be the primary beneficiary.

The results of operations for interim periods are not necessarily indicative of the results expected for the full year. Information for quarterly periods is affected by seasonal variations in sales, rate changes, electric fuel and other energy-related purchases, purchased gas expenses and other factors.

Certain amounts in Dominion’s and Virginia Power’s 2012 Consolidated Financial Statements and Notes have been reclassified to conform to the 2013 presentation for comparative purposes. The reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows.

Amounts disclosed for Dominion are inclusive of Virginia Power, where applicable.

Note 3. Dispositions

Sale of Brayton Point, Kincaid and Equity Method Investment in Elwood

In March 2013, Dominion entered into an agreement with Energy Capital Partners to sell Brayton Point, Kincaid, and its 50% interest in Elwood, which is an equity method investment.

PAGE16

The transaction is expected to close in the second quarter of 2013, subject to FERC approval. The sales price is approximately $472 million, subject to customary closing adjustments. In the first quarter of 2013, Brayton Point’s and Kincaid’s assets and liabilities to be disposed of were classified as held for sale and adjusted to their estimated fair value less cost to sell, resulting in a pre-tax impairment charge of $37 million ($22 million after-tax), which is included in discontinued operations in Dominion’s Consolidated Statement of Income. Dominion used the market approach to estimate the fair value of Brayton Point’s and Kincaid’s long-lived assets. This was considered a Level 2 fair value measurement given it was based on the agreed-upon sales price. The carrying amounts of the major classes of assets and liabilities classified as held for sale in Dominion’s Consolidated Balance Sheet are as follows:

At March 31,	2013
(millions)
Assets
Current assets	$	109
Property, plant and equipment, net		187
Other assets		17
Total assets	$	313
Liabilities
Current liabilities	$	28
Asset retirement obligations		19
Other liabilities		1
Total liabilities	$	48

The following table presents selected information regarding the results of operations of Brayton Point and Kincaid, which are reported as discontinued operations in Dominion’s Consolidated Statements of Income:

	Three Months Ended March 31,
	2013		2012
(millions)
Operating revenue	$	154	$	65
Income (loss) before income taxes		1		(22	)

Dominion’s 50% interest in Elwood is an equity method investment and therefore, in accordance with applicable accounting guidance, the carrying amount of this investment is not classified as held for sale nor are the equity earnings from this investment reported as discontinued operations.

Sale of Salem Harbor and State Line

In August 2012, Dominion completed the sale of Salem Harbor. During the second quarter of 2012, Dominion completed the sale of State Line, which ceased operations in March 2012.

The following table presents selected information regarding the results of operations of Salem Harbor and State Line, which are classified in discontinued operations in Dominion’s Consolidated Statement of Income:

Three months ended March 31,	2012
(millions)
Operating revenue	$	30
Income before income taxes		2

PAGE17

Note 4. Operating Revenue

The Companies’ operating revenue consists of the following:

	Three Months Ended March 31,
	2013		2012
(millions)
Dominion
Electric sales:
Regulated	$	1,761	$	1,724
Nonregulated		658		643
Gas sales:
Regulated		132		99
Nonregulated		345		398
Gas transportation and storage		467		405
Other		160		128
Total operating revenue	$	3,523	$	3,397
Virginia Power
Regulated electric sales	$	1,761	$	1,724
Other		20		30
Total operating revenue	$	1,781	$	1,754

Note 5. Income Taxes

For continuing operations, including noncontrolling interests, the statutory U.S. federal income tax rate reconciles to Dominion’s and Virginia Power’s effective income tax rate as follows:

	Dominion						Virginia Power
Three Months Ended March 31,	2013			2012			2013			2012
U.S. statutory rate		35.0	%		35.0	%		35.0	%		35.0	%
Increases (reductions) resulting from:
State taxes, net of federal benefit		4.0			4.0			3.9			3.9
Investment and production tax credits		(1.5	)		(0.5	)		—			—
Valuation allowances		0.1			(2.6	)		—			—
AFUDC – equity		(0.7	)		(0.7	)		(1.3	)		(0.9	)
Other, net		(0.4	)		(0.7	)		0.2			(0.2	)
Effective tax rate		36.5	%		34.5	%		37.8	%		37.8	%

Dominion’s effective tax rate in 2012 reflects a $20 million reduction of valuation allowance related to state operating loss carryforwards attributable to Fairless. After considering the results of Fairless’ operations in recent years and a forecast of future operating results reflecting Dominion’s planned purchase of the facility, Dominion concluded that it was more likely than not that the tax benefit of the operating losses would be realized. Significant assumptions included future commodity prices, in particular, those for electric energy produced by Fairless and those for natural gas, as compared to other fuels used for the generation of electricity, which would significantly influence the extent to which Fairless is dispatched by PJM.

As of March 31, 2013, there have been no material changes in Dominion’s and Virginia Power’s unrecognized tax benefits or possible changes that could reasonably be expected to occur during the next twelve months. See Note 5 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of these unrecognized tax benefits.

PAGE18

Note 6. Earnings Per Share

The following table presents the calculation of Dominion’s basic and diluted EPS:

	Three Months Ended March 31,
	2013		2012
(millions, except EPS)
Net income attributable to Dominion	$	495	$	494
Average shares of common stock outstanding – Basic		576.6		570.5
Net effect of potentially dilutive securities(1)		0.9		1.4
Average shares of common stock outstanding – Diluted		577.5		571.9
Earnings Per Common Share – Basic	$	0.86	$	0.86
Earnings Per Common Share – Diluted	$	0.86	$	0.86

(1) Potentially dilutive securities consist primarily of goal-based stock and contingently convertible senior notes.

There were no potentially dilutive securities excluded from the calculation of diluted EPS for the three months ended March 31, 2013 and 2012.

Note 8. Fair Value Measurements

Dominion’s and Virginia Power’s fair value measurements are made in accordance with the policies discussed in Note 6 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012. See Note 9 in this report for further information about their derivatives and hedge accounting activities.

Dominion and Virginia Power enter into certain physical and financial forwards and futures, options, and full requirements contracts, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards, futures, and full requirements contracts. An option model is used to value Level 3 physical and financial options. The discounted cash flow model for forwards and futures calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return, and credit spreads. Full requirements contracts add load shaping and usage factors in addition to the discounted cash flow model inputs. The option model calculates mark-to-market valuations using variations of the Black-Scholes option model. The inputs into the models are the forward market prices, implied price volatilities, mean reversions, risk-free rate of return, the option expiration dates, the option strike prices, price correlations, the original sales prices, and volumes. For Level 3 fair value measurements, the forward market prices, the implied price volatilities, price correlations, load shaping, and usage factors are considered unobservable. The unobservable inputs are developed and substantiated using historical information, available market data, third-party data, and statistical analysis. Periodically, inputs to valuation models are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third-party pricing sources.

PAGE21

The following table presents Dominion’s quantitative information about Level 3 fair value measurements. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility, price correlations, load shaping, and usage factors.

There were no unrealized gains or losses included in earnings in the Level 3 fair value category relating to assets/liabilities still held at the reporting date for the three months ended March 31, 2013 and 2012.

Fair Value of Financial Instruments

Substantially all of Dominion’s and Virginia Power’s financial instruments are recorded at fair value, with the exception of the instruments described below that are reported at historical cost. Estimated fair values have been determined using available market information and valuation methodologies considered appropriate by management. The carrying amount of cash and cash equivalents, customer and other receivables, short-term debt and accounts payable are representative of fair value because of the short-term nature of these instruments. For Dominion’s and Virginia Power’s financial instruments that are not recorded at fair value, the carrying amounts and estimated fair values are as follows:

	March 31, 2013				December 31, 2012
	Carrying Amount		Estimated  Fair Value(1)		Carrying Amount		Estimated  Fair Value(1)
(millions)
Dominion
Long-term debt, including securities due within one year(2)	$	17,097	$	19,874	$	16,841	$	19,898
Securities due within one year, VIE(3)		852		855		860		864
Junior subordinated notes		1,373		1,435		1,373		1,430
Subsidiary preferred stock(4)		257		260		257		255
Virginia Power
Long-term debt, including securities due within one year(2)	$	7,463	$	8,929	$	6,669	$	8,270
Preferred stock(4)		257		260		257		255

(1) Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issues with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value.

(2) Includes amounts which represent the unamortized discount and premium. At March 31, 2013 and December 31, 2012, includes the valuation of certain fair value hedges associated with Dominion’s fixed rate debt of approximately $72 million and $93 million, respectively.

(3) Includes amounts which represent the unamortized premium.

(4) Includes deferred issuance expenses of $2 million at March 31, 2013 and December 31, 2012.

Note 9. Derivatives and Hedge Accounting Activities

Dominion’s and Virginia Power’s accounting policies and objectives and strategies for using derivative instruments are discussed in Note 2 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012. See Note 8 in this report for further information about fair value measurements and associated valuation methods for derivatives.

Derivative assets and liabilities are presented gross on Dominion’s and Virginia Power’s Consolidated Balance Sheets. Dominion’s and Virginia Power’s derivative contracts include both over-the-counter transactions and those that are executed on

PAGE27

an exchange or other trading platform (exchange contracts) and centrally cleared. Over-the-counter contracts are bilateral contracts that are transacted directly with a third party. Exchange contracts utilize a financial intermediary, exchange, or clearinghouse to enter, execute, or clear the transactions. Certain over-the-counter and exchange contracts contain contractual rights of setoff through master netting arrangements, derivative clearing agreements, and contract default provisions. In addition, the contracts are subject to conditional rights of setoff through counterparty nonperformance, insolvency, or other conditions.

In general, most over-the-counter transactions and all exchange contracts are subject to collateral requirements. Types of collateral for over-the-counter and exchange contracts include cash, letters of credit, and in some cases other forms of security, none of which are subject to restrictions. Cash collateral is used in the table below to offset derivative assets and liabilities. Certain accounts receivable and accounts payable recognized on Dominion’s and Virginia Power’s Consolidated Balance Sheets, as well as letters of credit and other forms of security, all of which are not included in the tables below, are subject to offset under master netting agreements or similar agreements and would reduce the net exposure.

For the three months ended March 31, 2013 and 2012, gains or losses on hedging instruments determined to be ineffective and amounts excluded from the assessment of effectiveness were not material. Amounts excluded from the assessment of effectiveness include gains or losses attributable to changes in the time value of options and changes in the differences between spot prices and forward prices.

The following table presents selected information related to gains (losses) on cash flow hedges included in AOCI in Dominion’s Consolidated Balance Sheet at March 31, 2013:

	AOCI After-Tax			Amounts Expected to be Reclassified to Earnings during the next 12 Months After-Tax			Maximum Term
(millions)
Commodities:
Gas	$	(20	)	$	(14	)		31 months

Other		8			4			38 months
Interest rate		(155	)		(27	)		358 months
Total	$	(136	)	$	(49	)

The amounts that will be reclassified from AOCI to earnings will generally be offset by the recognition of the hedged transactions (e.g., anticipated sales) in earnings, thereby achieving the realization of prices contemplated by the underlying risk management strategies and will vary from the expected amounts presented above as a result of changes in market prices and interest rates.

PAGE40

(2) Reflects unrecovered gas costs at Dominion’s regulated gas operations, which are recovered through quarterly or annual filings with the applicable regulatory authority.

(3) Primarily reflects deferred fuel expenses for the Virginia jurisdiction of Virginia Power’s generation operations.

(4) Current regulatory assets are presented in other current assets in Dominion’s and Virginia Power’s Consolidated Balance Sheets.

(5) Represents unrecognized pension and other postretirement employee benefit costs expected to be recovered through future rates generally over the expected remaining service period of plan participants by certain of Dominion’s rate-regulated subsidiaries.

(6) Amounts to be recovered through future rates to pay income taxes that become payable when rate revenue is provided to recover AFUDC-equity and depreciation of property, plant and equipment for which deferred income taxes were not recognized for ratemaking purposes, including amounts attributable to tax rate changes.

(7) For jurisdictions subject to cost-based rate regulation, changes in the fair value of derivative instruments result in the recognition of regulatory assets or regulatory liabilities as they are expected to be recovered from or refunded to customers.

(8) Under PIPP, eligible customers can receive energy assistance based on their ability to pay. The difference between the customer’s total bill and the PIPP plan amount is deferred and collected or returned annually under the PIPP rider according to East Ohio tariff provisions.

(9) Current regulatory liabilities are presented in other current liabilities in Dominion’s and Virginia Power’s Consolidated Balance Sheets.

(10) Rates charged to customers by the Companies’ regulated businesses include a provision for the cost of future activities to remove assets that are expected to be incurred at the time of retirement.

(11) Primarily reflects a regulatory liability representing amounts collected from Virginia jurisdictional customers and placed in external trusts (including income, losses and changes in fair value thereon) for the future decommissioning of Virginia Power’s utility nuclear generation stations, in excess of the related AROs.

At March 31, 2013, approximately $128 million of Dominion’s and $84 million of Virginia Power’s regulatory assets represented past expenditures on which they do not currently earn a return. These expenditures are expected to be recovered within the next two years.

Note 12. Regulatory Matters

Regulatory Matters Involving Potential Loss Contingencies

As a result of issues generated in the ordinary course of business, Dominion and Virginia Power are involved in various regulatory matters. Certain regulatory matters may ultimately result in a loss; however, as such matters are in an initial procedural phase, involve uncertainty as to the outcome of pending reviews or orders, and/or involve significant factual issues that need to be resolved, it is not possible for the Companies to estimate a range of possible loss. For matters for which the Companies cannot estimate a range of possible loss, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the regulatory process such that the Companies are able to estimate a range of possible loss. For regulatory matters for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. This estimated range is based on currently available information and involves elements of judgment and significant uncertainties. This estimated range of possible loss may not represent the Companies’ maximum possible loss exposure. The circumstances of such regulatory matters will change from time to time and actual results may vary significantly from the current estimate. For current matters not specifically reported below, management does not anticipate that the outcome from such matters would have a material effect on Dominion’s or Virginia Power’s financial position, liquidity or results of operations.

FERC – Electric

Under the Federal Power Act, FERC regulates wholesale sales and transmission of electricity in interstate commerce by public utilities. Virginia Power purchases and sells electricity in the PJM wholesale market and Dominion’s merchant generators sell electricity in the PJM, MISO and ISO-NE wholesale markets under Dominion’s market-based sales tariffs authorized by FERC. In addition, Virginia Power has FERC approval of a tariff to sell wholesale power at capped rates based on its embedded cost of generation. This cost-based sales tariff could be used to sell to loads within or outside Virginia Power’s service territory. Any such sales would be voluntary.

Rates

In April 2008, FERC granted an application for Virginia Power’s electric transmission operations to establish a forward-looking formula rate mechanism that updates transmission rates on an annual basis and approved an ROE of 11.4%, effective as of January 1, 2008. The formula rate is designed to recover the expected revenue requirement for each calendar year and is updated based on actual costs. The FERC-approved formula method, which is based on projected costs, allows Virginia Power to earn a current return on its growing investment in electric transmission infrastructure.

In July 2008, Virginia Power filed an application with FERC requesting a revision to its revenue requirement to reflect an additional ROE incentive adder for eleven electric transmission enhancement projects. Under the proposal, the cost of transmission service would increase to include an ROE incentive adder for each of the eleven projects, beginning the date each project enters commercial operation (but not before January 1, 2009). Virginia Power proposed an incentive of 1.5% for four of the projects (including the Meadow Brook-to-Loudoun and Carson-to-Suffolk lines, which were completed in 2011) and an incentive of 1.25% for the other seven projects. In August 2008, FERC approved the proposal, effective September 1, 2008, the incentives were included in the PJM Tariff, and billing for the incentives was made accordingly. In 2012, PJM canceled one of

PAGE41

the eleven projects with an estimated cost of $7 million. The total cost for the other ten projects included in Virginia Power’s formula rate for 2013 is $852 million and the remaining projects were completed in 2012. Numerous parties sought rehearing of the FERC order in August 2008, and in May 2012 FERC denied rehearing. In July 2012, the North Carolina Commission filed an appeal of the FERC orders granting the incentives with the U.S. Court of Appeals for the Fourth Circuit. Although Virginia Power cannot predict the outcome of the appeal, it is not expected to have a material effect on results of operations.

In March 2010, ODEC and NCEMC filed a complaint with FERC against Virginia Power claiming that approximately $223 million in transmission costs related to specific projects were unjust, unreasonable and unduly discriminatory or preferential and should be excluded from Virginia Power’s transmission formula rate. ODEC and NCEMC requested that FERC establish procedures to determine the amount of costs for each applicable project that should be excluded from Virginia Power’s rates. In October 2010, FERC issued an order dismissing the complaint in part and established hearings and settlement procedures on the remaining part of the complaint. In February 2012, Virginia Power submitted to FERC a settlement agreement to resolve all issues set for hearing. All transmission customer parties to the proceeding joined the settlement. The Virginia Commission, North Carolina Commission and Public Staff of the North Carolina Commission, while not parties to the settlement, have agreed to not oppose the settlement. The settlement was accepted by FERC in May 2012 and provides for payment by Virginia Power to the transmission customer parties collectively of $250,000 per year for ten years and resolves all matters other than allocation of the incremental cost of certain underground transmission facilities, which has been briefed pursuant to FERC’s May 2012 order and awaits FERC action. While Virginia Power cannot predict the outcome of the briefing, it is not expected to have a material effect on results of operations.

Other Regulatory Matters

Other than the following matters, there have been no significant developments regarding the pending regulatory matters disclosed in Note 13 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

Virginia Regulation

2013 Biennial Review

Pursuant to the Regulation Act, in March 2013, Virginia Power submitted its base rate filings and accompanying schedules in support of the 2013 biennial review of its rates, terms and conditions, as well as of its earnings for test years 2011 and 2012. In its filing, Virginia Power did not request an increase in base rates for generation and distribution services, and proposed that base rates remain at their existing level as set by the Virginia Settlement Approval Order. Virginia Power’s earnings test analysis, as filed, demonstrates it earned an ROE of 10.11% on its generation and distribution services for the combined test period of 2011 and 2012. The Virginia Commission will determine whether Virginia Power’s earnings for the 2011 and 2012 test years, considered as a whole, were within 50 basis points above or below the authorized ROE of 10.9% established in the 2011 biennial review. If Virginia Power’s earnings for the test years are determined to be more than 50 basis points above the authorized ROE, the Virginia Commission will order a credit to customers of 60% of the earnings that exceeded an ROE of 11.4% for the biennial period. In such a scenario, the Virginia Commission can also order a reduction in Virginia Power’s base rates, but only if the resulting rates will provide Virginia Power with the opportunity to fully recover the costs of providing its services and earn not less than a fair combined rate of return on its distribution and generation services. If Virginia Power’s earnings for the test years are determined to be more than 50 basis points below the authorized ROE, the Virginia Commission can order an increase to Virginia Power’s rates if such an increase is necessary to provide Virginia Power the opportunity to fully recover the costs of providing services and to earn not less than a fair combined rate of return on its generation and distribution services. The Virginia Commission will also authorize an ROE for Virginia Power that will be applied to Riders R, S, W, B, and C1A and C2A, and that will also be utilized to measure base rate earnings as of January 1, 2013. Virginia Power is requesting authorization of an ROE of 11.5% effective January 1, 2014 through December 31, 2014 based on Virginia Power’s current cost of equity and performance. Pursuant to the Regulation Act, Virginia Power’s authorized ROE can be no lower than the average of the returns reported for the three previous years by not less than a majority of comparable utilities in the Southeastern U.S., with certain limitations as described in the Regulation Act. A final order in the 2013 biennial review for base rates must be issued no later than November 28, 2013.

DSM Riders C1A and C2A

In April 2013, the Virginia Commission approved revenue requirements for Riders C1A and C2A of approximately $4 million and $23 million, respectively, for the May 1, 2013 to April 30, 2014 rate year. The Virginia Commission approved a two-year extension of the Residential Low Income Program subject to an approximately $14 million cost cap, as well as a three-year extension of the Residential Air Conditioner Cycling Program. The Virginia Commission rejected Virginia Power’s request for approval of a process whereby the Virginia Commission Staff could administratively approve limited modifications to the designs of previously approved DSM programs. Virginia Power must file any application to continue Riders C1A and C2A by September 1, 2013.

PAGE42

Generation Rider S

The Virginia Commission previously approved Rider S in conjunction with the Virginia City Hybrid Energy Center. In March 2013, the Virginia Commission approved a revised revenue requirement for Rider S of approximately $248 million for the rate year beginning April 1, 2013, and stated that Virginia Power should file its next Rider S case by June 30, 2013.

Generation Rider B

In 2012, the Virginia Commission approved the conversion of the Altavista, Hopewell, and Southampton power stations to biomass, and in conjunction approved Rider B. In March 2013, the Virginia Commission approved a revenue requirement for the pre-commercial operations date period and the post-commercial operations date period, resulting in an average recovery amount of approximately $12 million for the rate year commencing April 1, 2013.

Solar Distributed Generation Demonstration Program

In March 2013, the Virginia Commission approved Rate Schedule SP, under which Virginia Power will purchase 100% of the energy output from up to a combined 3 MW of customer-owned solar distributed generation facilities, including all environmental attributes and associated renewable energy credits, at a fixed price of $0.15 per kWh for five years. This fixed price has two components: an avoided cost component (including line losses) determined using Virginia Power’s Rate Schedule 19 and recovered through Virginia Power’s fuel factor, and a voluntary environmental contribution component provided by customers voluntarily participating in Virginia Power’s Green Power Program.

Ohio Regulation

In 2008, East Ohio began PIR, aimed at replacing approximately 20% of its pipeline system. In February 2013, East Ohio filed an application with the Ohio Commission to adjust the cost recovery charge for costs associated with PIR investments for the calendar year 2012 and cumulatively. The application includes total gross plant investment for 2012 of $148 million, cumulative gross plant investment of $511 million, and a revenue requirement of $67 million. A stipulation was submitted by East Ohio and the Staff of the Ohio Commission that supports the rates filed by East Ohio. The Ohio Consumers’ Counsel neither supports nor opposes the stipulation and has raised no issues regarding the rates filed. The Ohio Commission issued an order approving the stipulation in April 2013.

FERC Gas Regulation

Sabinsville-to-Morrisville Project

In March 2013, FERC approved DTI’s Sabinsville-to-Morrisville project and authorized commencement of construction in the second quarter of 2013. The project is expected to have capacity of approximately 92,000 Dths per day, which will be leased by TGP to move additional Marcellus supplies from a TGP pipeline in northeast Pennsylvania to a DTI line in upstate New York. The project is expected to be placed into service in November 2013.

Tioga Area Expansion Project

In March 2013, DTI received FERC approval of the Tioga Area Expansion Project. The project is expected to provide approximately 270,000 Dths per day of firm transportation service from supply interconnects in Tioga and Potter Counties in Pennsylvania to DTI’s Crayne interconnect with Transcontinental Gas Pipe Line Company in Clinton County, Pennsylvania. Construction is expected to commence in the second quarter of 2013 with an anticipated in-service date of November 2013.

Note 13. Variable Interest Entities

As discussed in Note 15 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, certain variable pricing terms in some of the Companies’ long-term power and capacity contracts cause them to be considered variable interests in the counterparties.

Virginia Power has long-term power and capacity contracts with four non-utility generators with an aggregate summer generation capacity of approximately 870 MW. These contracts contain certain variable pricing mechanisms in the form of partial fuel reimbursement that Virginia Power considers to be variable interests. After an evaluation of the information provided by these entities, Virginia Power was unable to determine whether they were VIEs. However, the information they provided, as well as Virginia Power’s knowledge of generation facilities in Virginia, enabled Virginia Power to conclude that, if they were VIEs, it would not be the primary beneficiary. This conclusion reflects Virginia Power’s determination that its variable interests do not convey the power to direct the most significant activities that impact the economic performance of the entities during the remaining terms of Virginia Power’s contracts and for the years the entities are expected to operate after its contractual relationships expire. The contracts expire at various dates ranging from 2015 to 2021. Virginia Power is not subject to any risk of loss from these potential VIEs other than its remaining purchase commitments which totaled $1.0 billion as of March 31, 2013. Virginia Power paid $55 million for electric capacity and $20 million and $19 million for electric energy to these entities in the three months ended March 31, 2013 and 2012, respectively.

Virginia Power purchased shared services from DRS, an affiliated VIE, of approximately $77 million and $96 million for the three months ended March 31, 2013 and 2012, respectively. Virginia Power determined that it is not the most closely associated entity with DRS and therefore not the primary beneficiary. DRS provides accounting, legal, finance and certain administrative and technical services to all Dominion subsidiaries, including Virginia Power. Virginia Power has no obligation to absorb more than its allocated share of DRS costs.

PAGE43

See Note 15 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information about consolidated VIEs.

Note 14. Significant Financing Transactions

Credit Facilities and Short-term Debt

Dominion and Virginia Power use short-term debt to fund working capital requirements and as a bridge to long-term debt financings. The levels of borrowing may vary significantly during the course of the year, depending upon the timing and amount of cash requirements not satisfied by cash from operations. In addition, Dominion utilizes cash and letters of credit to fund collateral requirements. Collateral requirements are impacted by commodity prices, hedging levels, Dominion’s credit ratings and the credit quality of its counterparties.

At March 31, 2013, Dominion’s commercial paper and letters of credit outstanding, as well as capacity available under credit facilities, were as follows:

	Facility Limit		Outstanding Commercial Paper		Outstanding Letters of Credit		Facility Capacity Available
(millions)
Joint revolving credit facility(1)	$	3,000	$	2,003	$	—	$	997
Joint revolving credit facility(2)		500		—		19		481
Total	$	3,500	$	2,003	$	19	$	1,478

(1) This credit facility has a maturity date of September 2017, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion of letters of credit.

(2) The maturity date for $400 million of the $500 million in committed capacity of this credit facility is September 2017. The remaining $100 million has a maturity date of September 2016. This credit facility can be used to support bank borrowings, commercial paper and letter of credit issuances.

Virginia Power’s short-term financing is supported by two joint revolving credit facilities with Dominion. These credit facilities are being used for working capital, as support for the combined commercial paper programs of Dominion and Virginia Power and for other general corporate purposes.

At March 31, 2013, Virginia Power’s share of commercial paper and letters of credit outstanding, as well as its capacity available under its joint credit facilities with Dominion were as follows:

	Facility Sub-limit		Outstanding Commercial Paper		Outstanding Letters of Credit		Facility Sub-limit Capacity Available
(millions)
Joint revolving credit facility(1)	$	1,000	$	661	$	—	$	339
Joint revolving credit facility(2)		250		—		2		248
Total	$	1,250	$	661	$	2	$	587

(1) This credit facility has a maturity date of September 2017, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion (or the sub-limit, whichever is less) of letters of credit. Virginia Power’s current sub-limit under this credit facility can be increased or decreased multiple times per year.

(2) The maturity date for $400 million of the $500 million in committed capacity of this credit facility is September 2017. The remaining $100 million has a maturity date of September 2016. This credit facility can be used to support bank borrowings, commercial paper and letter of credit issuances. Virginia Power’s current sub-limit under this credit facility can be increased or decreased multiple times per year.

In addition to the credit facility commitments mentioned above, Virginia Power also has a $120 million credit facility with a maturity date of September 2017. This facility supports certain tax-exempt financings of Virginia Power.

Long-term Debt

In January 2013, Virginia Power issued $250 million of 1.2% senior notes and $500 million of 4.0% senior notes that mature in 2018 and 2043, respectively.

In March 2013, Virginia Power issued $500 million of 2.75% senior notes that mature in 2023.

PAGE44

In connection with the expected sale of Kincaid, in April 2013 Kincaid provided notice of redemption for its 7.33% senior secured bonds due June 15, 2020. The bonds are expected to be redeemed in May 2013 for approximately $186 million, including a make-whole premium and accrued interest. At March 31, 2013, the bonds were included in securities due within one year in Dominion’s Consolidated Balance Sheet.

In March 2013, Virginia Power redeemed the $50 million 2.5% Industrial Development Authority of the Town of Louisa, Virginia Solid Waste and Sewage Disposal Revenue Bonds, Series 2001A, that would have otherwise matured in March 2031.

Convertible Securities

At March 31, 2013, Dominion had $72 million of outstanding contingent convertible senior notes that are convertible by holders into a combination of cash and shares of Dominion’s common stock under certain circumstances. The conversion feature requires that the principal amount of each note be repaid in cash, while amounts payable in excess of the principal amount will be paid in common stock. The conversion rate is subject to adjustment upon certain events such as subdivisions, splits, combinations of common stock or the issuance to all common stock holders of certain common stock rights, warrants or options and certain dividend increases. As of March 31, 2013, the conversion rate had been adjusted, primarily due to individual dividend payments above the level paid at issuance, to 29.5147 shares of common stock per $1,000 principal amount of senior notes, which represents a conversion price of $33.88. If the outstanding notes as of March 31, 2013 were all converted, it would result in the issuance of approximately 900 thousand additional shares.

The senior notes are eligible for conversion during any calendar quarter when the closing price of Dominion’s common stock was equal to or higher than 120% of the conversion price for at least 20 out of the last 30 consecutive trading days of the preceding quarter. During the three months ended March 31, 2013, the senior notes were eligible for conversion and approximately $10 million of the notes were converted by holders. The senior notes are eligible for conversion during the second quarter of 2013.

Junior Subordinated Notes Payable to Affiliated Trusts

In January 2013, Dominion repaid its $258 million 7.83% unsecured junior subordinated debentures and redeemed all 250 thousand units of the $250 million 7.83% Dominion Resources Capital Trust I capital securities due December 1, 2027. The securities were redeemed at a price of $1,019.58 per capital security plus accrued and unpaid distributions.

Note 15. Commitments and Contingencies

As a result of issues generated in the ordinary course of business, Dominion and Virginia Power are involved in legal proceedings before various courts and are periodically subject to governmental examinations (including by regulatory authorities), inquiries and investigations. Certain legal proceedings and governmental examinations involve demands for unspecified amounts of damages, are in an initial procedural phase, involve uncertainty as to the outcome of pending appeals or motions, or involve significant factual issues that need to be resolved, such that it is not possible for the Companies to estimate a range of possible loss. For such matters that the Companies cannot estimate, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the litigation or investigative processes such that the Companies are able to estimate a range of possible loss. For legal proceedings and governmental examinations for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Estimated ranges of loss are inclusive of legal fees and net of any anticipated insurance recoveries. This estimated range is based on currently available information and involves elements of judgment and significant uncertainties. This estimated range of possible loss may not represent the Companies’ maximum possible loss exposure. The circumstances of such legal proceedings and governmental examinations will change from time to time and actual results may vary significantly from the current estimate. For current proceedings not specifically reported below, management does not anticipate that the liabilities, if any, arising from such proceedings would have a material effect on Dominion’s or Virginia Power’s financial position, liquidity or results of operations.

Environmental Matters

Dominion and Virginia Power are subject to costs resulting from a number of federal, state and local laws and regulations designed to protect human health and the environment. These laws and regulations affect future planning and existing operations. They can result in increased capital, operating and other costs as a result of compliance, remediation, containment and monitoring obligations.

Air

The CAA, as amended, is a comprehensive program utilizing a broad range of regulatory tools to protect and preserve the nation’s air quality. At a minimum, states are required to establish regulatory programs to address all requirements of the CAA. However, states may choose to develop regulatory programs that are more restrictive. Many of Dominion’s and Virginia Power’s facilities are subject to the CAA’s permitting and other requirements.

PAGE45

The EPA established CAIR with the intent to require significant reductions in SO₂ and NO_X emissions from electric generating facilities. In July 2008, the U.S. Court of Appeals for the D.C. Circuit issued a ruling vacating CAIR. In December 2008, the Court denied rehearing, but also issued a decision to remand CAIR to the EPA. In July 2011, the EPA issued a replacement rule for CAIR, called CSAPR, that required 28 states to reduce power plant emissions that cross state lines. CSAPR established new SO₂ and NO_x emissions cap and trade programs that were completely independent of the current ARP. Specifically, CSAPR required reductions in SO₂ and NO_x emissions from fossil fuel-fired electric generating units of 25 MW or more through annual NO_x emissions caps, NO_x emissions caps during the ozone season (May 1 through September 30) and annual SO₂ emission caps with differing requirements for two groups of affected states.

Following numerous petitions by industry participants for review and motions for stay, the U.S. Court of Appeals for the D.C. Circuit issued a ruling in December 2011 to stay CSAPR pending judicial review. In February and June 2012, the EPA issued technical revisions to CSAPR that are not material to Dominion. In August 2012, the Court vacated CSAPR in its entirety and ordered the EPA to implement CAIR until a valid replacement rule is issued. In October 2012, the EPA filed a petition requesting a rehearing of the court’s decision, which was denied in January 2013. The mandate vacating CSAPR was issued in February 2013. In March 2013, the EPA and several environmental groups filed petitions with the U.S. Supreme Court requesting review of the decision to vacate and remand CSAPR. With respect to Dominion’s generation fleet, the cost to comply with CAIR is not expected to be material. Future outcomes of litigation and/or any additional action to issue a revised rule could affect the assessment regarding cost of compliance.

In May 2012, the EPA issued final designations for the 75-ppb ozone air quality standard. Several Dominion electric generating facilities are located in areas impacted by this standard. As part of the standard, states will be required to develop and implement plans to address sources emitting pollutants which contribute to the formation of ozone. Until the states have developed implementation plans, Dominion is unable to predict whether or to what extent the new rules will ultimately require additional controls.

In February 2008, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA. The request concerns historical operating changes and capital improvements undertaken at State Line and Kincaid. In April 2009, Dominion received a second request for information. Dominion provided information in response to both requests. Also in April 2009, Dominion received a Notice and Finding of Violations from the EPA claiming violations of the CAA New Source Review requirements, NSPS, the Title V permit program and the stations’ respective State Implementation Plans. In May 2010, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA. The request concerns historical operating changes and capital improvements undertaken at Brayton Point.

Dominion believes that it complied with applicable laws and the EPA regulations and interpretations in effect at the time the work in question took place. Dominion entered into settlement discussions with the U.S. government and reached an agreement to settle the allegations. In April 2013, the U.S. government lodged a consent decree and complaint with the U.S. District Court for the Central District of Illinois that resolves all alleged violations at State Line, Kincaid and Brayton Point. The settlement mandates the closure of State Line, installation of certain control technology at Kincaid and Brayton Point, the achievement of certain emissions limitations, payment of a civil penalty of $3 million and funding of $10 million in environmental mitigation projects. The consent decree will undergo a 30-day public comment period and is expected to be entered by the court thereafter. Dominion previously accrued a liability of $13 million related to this matter. State Line ceased operations in March 2012 and was sold in June 2012. The installation of pollution control technology is in progress at Kincaid and has been completed at Brayton Point. While Dominion has agreed to sell Kincaid and Brayton Point, under the terms of the sale transaction Dominion will retain the $13 million liability associated with the settlement agreement.

Water

The CWA, as amended, is a comprehensive program requiring a broad range of regulatory tools including a permit program to authorize and regulate discharges to surface waters with strong enforcement mechanisms. Dominion and Virginia Power must comply with all aspects of the CWA programs at their operating facilities.

In September 2010, Millstone’s NPDES permit was reissued under the CWA. The conditions of the permit require an evaluation of control technologies that could result in additional expenditures in the future. The report summarizing the results of the evaluation was submitted in August 2012 and is under review by the Connecticut Department of Energy and Environmental Protection. Dominion cannot currently predict the outcome of this review. In October 2010, the permit issuance was appealed to the state court by a private plaintiff. The permit is expected to remain in effect during the appeal. Dominion is currently unable to make an estimate of the potential financial statement impacts related to this matter.

Solid and Hazardous Waste

The CERCLA, as amended, provides for immediate response and removal actions coordinated by the EPA in the event of threatened releases of hazardous substances into the environment and authorizes the U.S. government either to clean up sites at which hazardous substances have created actual or potential environmental hazards or to order persons responsible for the

PAGE46

situation to do so. Under the CERCLA, as amended, generators and transporters of hazardous substances, as well as past and present owners and operators of contaminated sites, can be jointly, severally and strictly liable for the cost of cleanup. These potentially responsible parties can be ordered to perform a cleanup, be sued for costs associated with an EPA-directed cleanup, voluntarily settle with the U.S. government concerning their liability for cleanup costs, or voluntarily begin a site investigation and site remediation under state oversight.

From time to time, Dominion or Virginia Power may be identified as a potentially responsible party to a Superfund site. The EPA (or a state) can either allow such a party to conduct and pay for a remedial investigation, feasibility study and remedial action or conduct the remedial investigation and action itself and then seek reimbursement from the potentially responsible parties. Each party can be held jointly, severally and strictly liable for the cleanup costs. These parties can also bring contribution actions against each other and seek reimbursement from their insurance companies. As a result, Dominion or Virginia Power may be responsible for the costs of remedial investigation and actions under the Superfund law or other laws or regulations regarding the remediation of waste. Except as noted below, the Companies do not believe this will have a material effect on results of operations, financial condition and/or cash flows.

In September 2011, the EPA issued a UAO to Virginia Power and 22 other parties, ordering specific remedial action of certain areas at the Ward Transformer Superfund site located in Raleigh, North Carolina. Virginia Power does not believe it is a liable party under CERCLA based on its alleged connection to the site. In November 2011, Virginia Power and a number of other parties notified the EPA that they are declining to undertake the work set forth in the UAO.

The EPA may seek to enforce a UAO in court pursuant to its enforcement authority under CERCLA, and may seek recovery of its costs in undertaking removal or remedial action. If the court determines that a respondent failed to comply with the UAO without sufficient cause, the EPA may also seek civil penalties of up to $37,500 per day for the violation and punitive damages of up to three times the costs incurred by the EPA as a result of the party’s failure to comply with the UAO. Virginia Power is currently unable to make an estimate of the potential financial statement impacts related to the Ward Transformer matter.

Dominion has determined that it is associated with 17 former manufactured gas plant sites, three of which pertain to Virginia Power. Studies conducted by other utilities at their former manufactured gas plant sites have indicated that those sites contain coal tar and other potentially harmful materials. None of the former sites with which Dominion and Virginia Power are associated is under investigation by any state or federal environmental agency. At one of the former sites, Dominion is conducting a state-approved post closure groundwater monitoring program and an environmental land use restriction has been recorded. Another site has been accepted into a state-based voluntary remediation program. Dominion is currently evaluating the nature and extent of the contamination from this site as well as potential remedial options, but is not yet able to estimate the future remediation costs. Due to the uncertainty surrounding these sites, Dominion is unable to make an estimate of the potential financial statement impacts related to these sites.

Climate Change Legislation and Regulation

Massachusetts, Rhode Island and Connecticut, among other states, have joined RGGI, a multi-state effort to reduce CO₂ emissions in the Northeast implemented through state specific regulations. Under the initiative, aggregate CO₂ emissions from power plants in participating states are required to be stabilized at current levels from 2009 to 2015. Further reductions from current levels would be required to be phased in starting in 2016 such that by 2019 there would be a 10% reduction in participating state power plant CO₂ emissions. During 2012, RGGI underwent a program review, and in February 2013, revisions to the RGGI model rule were issued. Dominion is in the process of evaluating these revisions as to potential impacts on Dominion’s fossil fired generation operations in RGGI states. Until this evaluation is completed, Dominion is unable to estimate the potential financial statement impacts related to the program review.

Nuclear Matters

In March 2011, a magnitude 9.0 earthquake and subsequent tsunami caused significant damage at the Fukushima Daiichi nuclear power station in northeast Japan. These events have resulted in significant nuclear safety reviews required by the NRC and industry groups such as INPO. Like other U.S. nuclear operators, Dominion has been gathering supporting data and participating in industry initiatives focused on the ability to respond to and mitigate the consequences of design-basis and beyond-design-basis events at its stations.

In July 2011, an NRC task force provided initial recommendations based on its review of the Fukushima Daiichi accident and in October 2011 the NRC staff prioritized these recommendations into Tiers 1, 2 and 3, with the Tier 1 recommendations consisting of actions which the staff determined should be started without unnecessary delay. In December 2011, the NRC Commissioners approved the agency staff’s prioritization and recommendations; and that same month an appropriations act directed the NRC to require reevaluation of external hazards (not limited to seismic and flooding hazards) as soon as possible.

Based on the prioritized recommendations, in March 2012, the NRC issued orders and information requests requiring specific reviews and actions to all operating reactors, construction permit holders and combined license holders based on the lessons

PAGE47

learned from the Fukushima Daiichi event. The orders applicable to Dominion require implementation of safety enhancements related to mitigation strategies to respond to extreme natural events resulting in the loss of power at plants, and enhancing spent fuel pool instrumentation. The orders require prompt implementation of the safety enhancements and completion of implementation within two refueling outages or by December 31, 2016, whichever comes first. The information requests issued by the NRC request each reactor to reevaluate the seismic and flooding hazards at their site using present-day methods and information, conduct walkdowns of their facilities to ensure protection against the hazards in their current design basis, and to reevaluate their emergency communications systems and staffing levels. Dominion and Virginia Power do not currently expect that compliance with the NRC’s March 2012 orders and information requests will materially impact their financial position, results of operations or cash flows during the approximately four-year implementation period. The NRC staff is evaluating the implementation of the longer term Tier 2 and Tier 3 recommendations. Dominion and Virginia Power are currently unable to estimate the potential financial impacts related to compliance with Tier 2 and Tier 3 recommendations.

Guarantees

Dominion

At March 31, 2013, Dominion had issued $89 million of guarantees, primarily to support equity method investees. No significant amounts related to these guarantees have been recorded. As of March 31, 2013, Dominion’s exposure under these guarantees was $59 million, primarily related to certain reserve requirements associated with non-recourse financing.

In addition to the above guarantees, Dominion and its partners, Shell and BP, may be required to make additional periodic equity contributions to NedPower and Fowler Ridge in connection with certain funding requirements associated with their respective non-recourse financings. As of March 31, 2013, Dominion’s maximum remaining cumulative exposure under these equity funding agreements is $98 million through 2019 and its maximum annual future contributions could range from approximately $4 million to $19 million.

Dominion also enters into guarantee arrangements on behalf of its consolidated subsidiaries, primarily to facilitate their commercial transactions with third parties. To the extent that a liability subject to a guarantee has been incurred by one of Dominion’s consolidated subsidiaries, that liability is included in the Consolidated Financial Statements. Dominion is not required to recognize liabilities for guarantees issued on behalf of its subsidiaries unless it becomes probable that it will have to perform under the guarantees. Terms of the guarantees typically end once obligations have been paid. Dominion currently believes it is unlikely that it would be required to perform or otherwise incur any losses associated with guarantees of its subsidiaries’ obligations.

At March 31, 2013, Dominion had issued the following subsidiary guarantees:

	Stated Limit		Value(1)
(millions)
Subsidiary debt(2)	$	363	$	363
Commodity transactions(3)		3,019		341
Nuclear obligations(4)		232		51
Other(5)		638		108
Total	$	4,252	$	863

(1) Represents the estimated portion of the guarantee’s stated limit that is utilized as of March 31, 2013 based upon prevailing economic conditions and fact patterns specific to each guarantee arrangement. For those guarantees related to obligations that are recorded as liabilities by Dominion’s subsidiaries, the value includes the recorded amount.

(2) Guarantees of debt of certain DEI subsidiaries. In the event of default by the subsidiaries, Dominion would be obligated to repay such amounts.

(3) Guarantees related to energy trading and marketing activities and other commodity commitments of certain subsidiaries, including subsidiaries of Virginia Power and DEI. These guarantees were provided to counterparties in order to facilitate physical and financial transactions in gas, oil, electricity, pipeline capacity, transportation and related commodities and services. If any of these subsidiaries fail to perform or pay under the contracts and the counterparties seek performance or payment, Dominion would be obligated to satisfy such obligation. Dominion and its subsidiaries receive similar guarantees as collateral for credit extended to others. The value provided includes certain guarantees that do not have stated limits.

(4) Guarantees related to certain DEI subsidiaries’ potential retrospective premiums that could be assessed if there is a nuclear incident under Dominion’s nuclear insurance programs and guarantees for a DEI subsidiary’s and Virginia Power’s commitment to buy nuclear fuel. Excludes Dominion’s agreement to provide up to $150 million and $60 million to two DEI subsidiaries to pay the operating expenses of Millstone and Kewaunee, respectively, in the event of a prolonged outage, as part of satisfying certain NRC requirements concerned with ensuring adequate funding for the operations of nuclear power stations. The agreement for Kewaunee also provides for funds through the completion of decommissioning.

(5) Guarantees related to other miscellaneous contractual obligations such as leases, environmental obligations and construction projects. Also includes guarantees related to certain DEI subsidiaries’ obligations for equity capital contributions and energy generation associated with Fowler Ridge and NedPower.

PAGE48

In April 2013, Dominion entered into guarantee arrangements on behalf of Cove Point to facilitate the liquefaction project. These agreements include guarantees supporting the terminal services and transportation agreements as well as the engineering, procurement and construction contract for the new liquefaction facilities. Two of the guarantees have no stated limit, one guarantee has a $150 million limit, and one guarantee has a $1.75 billion aggregate limit with an annual draw limit of $175 million.

Surety Bonds and Letters of Credit

As of March 31, 2013, Dominion had purchased $150 million of surety bonds, including $56 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $19 million, including $2 million at Virginia Power, to facilitate commercial transactions by its subsidiaries with third parties. Under the terms of surety bonds, the Companies are obligated to indemnify the respective surety bond company for any amounts paid.

Note 16. Credit Risk

Dominion’s and Virginia Power’s accounting policies for credit risk are discussed in Note 23 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012.

At March 31, 2013, Dominion’s gross credit exposure totaled $552 million. After the application of collateral, credit exposure was reduced to $551 million. Of this amount, investment grade counterparties, including those internally rated, represented 80%. One counterparty exposure represented 10% of Dominion’s total exposure and is a utility holding company rated investment grade. At March 31, 2013, Virginia Power’s exposure to potential concentrations of credit risk was not material.

Credit-Related Contingent Provisions

The majority of Dominion’s derivative instruments contain credit-related contingent provisions. These provisions require Dominion to provide collateral upon the occurrence of specific events, primarily a credit rating downgrade. If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered as of March 31, 2013 and December 31, 2012, Dominion would have been required to post an additional $58 million and $110 million, respectively, of collateral to its counterparties. The collateral that would be required to be posted includes the impacts of any offsetting asset positions and any amounts already posted for derivatives, non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. Dominion had posted $9 million in collateral at March 31, 2013 and $4 million in collateral at December 31, 2012, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. The collateral posted includes any amounts paid related to non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. The aggregate fair value of all derivative instruments with credit-related contingent provisions that are in a liability position and not fully collateralized with cash as of March 31, 2013 and December 31, 2012 was $108 million and $163 million, respectively, which does not include the impact of any offsetting asset positions. Credit-related contingent provisions for Virginia Power were not material as of March 31, 2013 and December 31, 2012. See Note 9 for further information about derivative instruments.

Note 17. Related Party Transactions

Virginia Power engages in related-party transactions primarily with other Dominion subsidiaries (affiliates). Virginia Power’s receivable and payable balances with affiliates are settled based on contractual terms or on a monthly basis, depending on the nature of the underlying transactions. Virginia Power is included in Dominion’s consolidated federal income tax return and participates in certain Dominion benefit plans. A discussion of significant related party transactions follows.

Transactions with Affiliates

Virginia Power transacts with affiliates for certain quantities of natural gas and other commodities in the ordinary course of business. Virginia Power also enters into certain commodity derivative contracts with affiliates. Virginia Power uses these contracts, which are principally comprised of commodity swaps, to manage commodity price risk associated with purchases of natural gas. As of March 31, 2013 and December 31, 2012, Virginia Power’s derivative liabilities with affiliates were not material.

DRS and other affiliates provide accounting, legal, finance and certain administrative and technical services to Virginia Power.

PAGE49

Presented below are significant transactions with DRS and other affiliates:

	Three Months Ended March 31,
	2013		2012
(millions)
Commodity purchases from affiliates	$	85	$	78

Virginia Power has borrowed funds from Dominion under short-term borrowing arrangements. There were $57 million and $243 million in short-term demand note borrowings from Dominion as of March 31, 2013 and December 31, 2012, respectively. Virginia Power’s outstanding borrowings, net of repayments, under the Dominion money pool for its nonregulated subsidiaries totaled $192 million as of December 31, 2012. There were no borrowings as of March 31, 2013. Interest charges related to Virginia Power’s borrowings from Dominion were not material for the three months ended March 31, 2013 and 2012.

Note 18. Employee Benefit Plans

The components of Dominion’s provision for net periodic benefit cost were as follows:

	Pension Benefits						Other Postretirement Benefits
	2013			2012			2013			2012
(millions)

Amortization of net loss		46			33			2			2
Net periodic benefit cost	$	34		$	22		$	8		$	9

Employer Contributions

During the three months ended March 31, 2013, Dominion made no contributions to its defined benefit pension plans or other postretirement benefit plans. Dominion expects to contribute approximately $12 million to its other postretirement benefit plans through Voluntary Employees’ Beneficiary Associations during the remainder of 2013.

Note 19. Operating Segments

Dominion and Virginia Power are organized primarily on the basis of products and services sold in the U.S. A description of the operations included in the Companies’ primary operating segments is as follows:

Primary Operating Segment	Description of Operations	Dominion	Virginia Power
DVP	Regulated electric distribution	X	X
	Regulated electric transmission	X	X

In addition to the operating segments above, the Companies also report a Corporate and Other segment.

The Corporate and Other Segment of Dominion includes its corporate, service company and other functions (including unallocated debt) and the net impact of operations that are expected to be or are currently discontinued. In addition, Corporate and Other includes specific items attributable to Dominion’s operating segments that are not included in profit measures evaluated by executive management in assessing the segments’ performance or allocating resources among the segments.

PAGE50

In the three months ended March 31, 2013, Dominion reported an after-tax net benefit of $19 million for specific items in the Corporate and Other segment, with $17 million of these net benefits attributable to its operating segments. In the three months ended March 31, 2012, Dominion reported after-tax net expense of $3 million for specific items in the Corporate and Other segment, all of which was attributable to its operating segments.

The net benefit for specific items in 2013 primarily related to the impact of the following items:

• A $44 million ($26 million after-tax) net gain on investments held in nuclear decommissioning trust funds, attributable to Dominion Generation; and

• A $1 million net benefit related to Brayton Point and Kincaid, including a $38 million ($23 million after-tax) benefit from the discontinued operations of these merchant power stations partially offset by impairments of $37 million ($22 million after-tax) related to these stations, attributable to Dominion Generation.

The net expense for specific items in 2012 primarily related to the impact of the following items:

• A $22 million ($11 million after-tax) loss from the discontinued operations of Brayton Point and Kincaid, attributable to Dominion Generation; partially offset by

• A $15 million ($9 million after-tax) net gain on investments held in nuclear decommissioning trust funds, attributable to Dominion Generation.

The Corporate and Other Segment of Virginia Power primarily includes specific items attributable to its operating segments that are not included in profit measures evaluated by executive management in assessing the segments’ performance or allocating resources among the segments.

There were no material net benefit or expense items in the Corporate and Other segment in the three months ended March 31, 2013 or 2012.

An analysis of Dominion’s results of operations follows:

First Quarter 2013 vs. 2012

Net revenue increased 3%, primarily reflecting:

• A $96 million increase from electric utility operations primarily reflecting:

• The impact ($63 million) of an increase in sales to retail customers primarily due to an increase in heating degree days ($73 million), partially offset by a decrease in sales due to the effect of unfavorable economic conditions on customer usage and other factors ($10 million); and

• An increase in rate adjustment clause revenue ($25 million); and

• A $25 million increase from regulated natural gas transmission operations primarily related to the Appalachian Gateway Project that was placed into service in September 2012.

These increases were partially offset by:

• A $51 million decrease in retail energy marketing activities primarily due to price risk management activities; and

• A $19 million decrease from merchant generation operations primarily reflecting lower generation output.

Other operations and maintenance increased 3%, primarily reflecting:

• A $33 million increase in salaries, wages and benefits;

• A $14 million increase in storm damage and service restoration costs; and

• A $17 million increase due to the impact of various other individually immaterial and unrelated items.

These increases were partially offset by:

• A $25 million gain from the contribution of Line TL-404 to Blue Racer; and

• A $23 million decrease in certain electric transmission-related expenditures. These expenses are recovered through FERC rates.

Depreciation, depletion and amortization increased 9%, primarily due to property additions.

• A $23 million decrease in certain electric transmission-related expenditures. These expenses are recovered through FERC rates.

Depreciation and amortization increased 10%, primarily due to property additions.

Income tax expense increased 18%, primarily reflecting higher pre-tax income in 2013.

Selected Information – Energy Trading Activities

Dominion engages in energy trading, marketing and hedging activities to complement its businesses and facilitate its price risk management activities. As part of these operations, Dominion enters into contracts for purchases and sales of energy-related commodities, including electricity, natural gas and other energy-related products. Settlements of contracts may require physical delivery of the underlying commodity or cash settlement. Dominion also enters into contracts with the objective of benefiting from changes in prices. For example, after entering into a contract to purchase a commodity, Dominion typically enters into a sales contract, or a combination of sales contracts, with quantities and delivery or settlement terms that are identical or very similar to those of the purchase contract. When the purchase and sales contracts are settled either by physical delivery of the underlying commodity or by net cash settlement, Dominion may receive a net cash margin (a realized gain), or may pay a net cash margin (a realized loss). Dominion continually monitors its contract positions, considering location and timing of delivery or settlement for each energy commodity in relation to market price activity.

A summary of the changes in the unrealized gains and losses recognized for Dominion’s energy-related derivative instruments held for trading purposes follows:

	Amount
(millions)
Net unrealized gains at December 31, 2012	$	78
Contracts realized or otherwise settled during the period		(40	)
Change in unrealized gains and losses		12
Net unrealized gains at March 31, 2013	$	50

The balance of net unrealized gains and losses recognized for Dominion’s energy-related derivative instruments held for trading purposes at March 31, 2013, is summarized in the following table based on the approach used to determine fair value:

Maturity Based on Contract Settlement or Delivery Date(s)
Sources of Fair Value	2013			2014 – 2015			2016 – 2017			2018 and thereafter		Total

Total	$	30		$	22		$	(2	)	$	—	$	50

(1) Values represent observable unadjusted quoted prices for traded instruments in active markets.

(2) Values with inputs that are observable directly or indirectly for the instrument, but do not qualify for Level 1.

(3) Values with a significant amount of inputs that are not observable for the instrument.

Liquidity and Capital Resources

Dominion and Virginia Power depend on both internal and external sources of liquidity to provide working capital and as a bridge to long-term debt financings. Short-term cash requirements not met by cash provided by operations are generally satisfied with proceeds from short-term borrowings. Long-term cash needs are met through issuances of debt and/or equity securities.

At March 31, 2013, Dominion had $1.5 billion of unused capacity under its credit facilities, including $587 million of unused capacity under joint credit facilities available to Virginia Power.

The dispositions of certain merchant generation facilities during 2012 and the expected sale or decommissioning of certain other merchant generation facilities in 2013 are not expected to negatively impact Dominion’s liquidity.

Operating Cash Flows

Net cash provided by Dominion’s operating activities decreased by $571 million, primarily due to lower deferred fuel cost recoveries in its Virginia jurisdiction in 2013 as compared to 2012, higher net margin collateral requirements, and the absence of income tax refunds received in 2012. The decrease was partially offset by the impact of more favorable weather in 2013 as compared to 2012.

Net cash provided by Virginia Power’s operating activities decreased by $199 million, primarily due to lower deferred fuel cost recoveries in 2013 as compared to 2012 and net changes in other working capital items. The decrease was partially offset by the impact of more favorable weather.

Dominion believes that its operations provide a stable source of cash flow to contribute to planned levels of capital expenditures and maintain or grow the dividend on common shares. Virginia Power believes that its operations provide a stable source of cash flow to contribute to planned levels of capital expenditures and provide dividends to Dominion.

The Companies’ operations are subject to risks and uncertainties that may negatively impact the timing or amounts of operating cash flows, which are discussed in Item 1A. Risk Factors in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 and in Part II, Item 1A. Risk Factors in this report.

PAGE63

Credit Risk

Dominion’s exposure to potential concentrations of credit risk results primarily from its energy marketing and price risk management activities. Presented below is a summary of Dominion’s credit exposure as of March 31, 2013 for these activities. Gross credit exposure for each counterparty is calculated prior to the application of collateral and represents outstanding receivables plus any unrealized on- or off-balance sheet exposure, taking into account contractual netting rights.

	Gross  Credit Exposure		Credit Collateral		Net Credit Exposure
(millions)
Investment grade(1)	$	322	$	—	$	322
Non-investment grade(2)		4		—		4
No external ratings:
Internally rated – investment grade(3)		117		—		117
Internally rated – non-investment grade(4)		109		1		108
Total	$	552	$	1	$	551

(1) Designations as investment grade are based upon minimum credit ratings assigned by Moody’s and Standard & Poor’s. The five largest counterparty exposures, combined, for this category represented approximately 32% of the total net credit exposure.

(2) The five largest counterparty exposures, combined, for this category represented approximately 1% of the total net credit exposure.

(3) The five largest counterparty exposures, combined, for this category represented approximately 12% of the total net credit exposure.

(4) The five largest counterparty exposures, combined, for this category represented approximately 13% of the total net credit exposure.

Virginia Power’s exposure to potential concentrations of credit risk results primarily from sales to wholesale customers and was not material at March 31, 2013.

Investing Cash Flows

Net cash used in Dominion’s investing activities decreased by $84 million, primarily due to lower capital expenditures.

Net cash used in Virginia Power’s investing activities increased by $97 million, primarily due to higher capital expenditures.

Financing Cash Flows and Liquidity

Dominion and Virginia Power rely on capital markets as significant sources of funding for capital requirements not satisfied by cash provided by their operations. As discussed further in Credit Ratings and Debt Covenants in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, the Companies’ ability to borrow funds or issue securities and the return demanded by investors are affected by credit ratings. In addition, the raising of external capital is subject to certain regulatory requirements, including registration with the SEC and, in the case of Virginia Power, approval by the Virginia Commission.

Each of the Companies meets the definition of a well-known seasoned issuer under SEC rules governing the registration, communications and offering processes under the Securities Act of 1933, as amended. The rules provide for a streamlined shelf registration process to provide registrants with timely access to capital. This allows the Companies to use automatic shelf registration statements to register any offering of securities, other than those for exchange offers or business combination transactions.

Net cash used in Dominion’s financing activities decreased by $243 million, primarily due to lower net debt repayments in 2013 as compared to 2012 as a result of lower cash inflow from operations.

Net cash used in Virgina Power’s financing activities decreased by $272 million, primarily due to net debt issuances in 2013 as compared to net debt repayments in 2012 as a result of lower cash inflow from operations.

See Note 14 to the Consolidated Financial Statements in this report for further information regarding Dominion’s and Virginia Power’s credit facilities, liquidity and significant financing transactions.

PAGE64

Credit Ratings

Credit ratings are intended to provide banks and capital market participants with a framework for comparing the credit quality of securities and are not a recommendation to buy, sell or hold securities. In the Credit Ratings section of MD&A in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, there is a discussion on the use of capital markets by the Companies, as well as the impact of credit ratings on the accessibility and costs of using these markets. As of March 31, 2013, there have been no changes in the Companies’ credit ratings.

Debt Covenants

In the Debt Covenants section of MD&A in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, there is a discussion on the various covenants present in the enabling agreements underlying the Companies’ debt. As of March 31, 2013, there have been no material changes to debt covenants, nor any events of default under the Companies’ debt covenants.

Future Cash Payments for Contractual Obligations and Planned Capital Expenditures

As of March 31, 2013, there have been no material changes outside the ordinary course of business to Dominion’s or Virginia Power’s contractual obligations as disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2012.

As of March 31, 2013, Dominion’s planned capital expenditures for 2013, 2014 and 2015 are expected to total approximately $5.1 billion, $5.1 billion and $4.3 billion, respectively. The increase in planned capital expenditures, as compared to the amounts originally forecasted in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2012, primarily reflects the planned construction of the Cove Point liquefaction project in Maryland. There have been no material changes to Virginia Power’s planned capital expenditures.

Use of Off-Balance Sheet Arrangements

As of March 31, 2013, there have been no material changes in the off-balance sheet arrangements disclosed in MD&A in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2012.

Future Issues and Other Matters

The following discussion of future issues and other information includes current developments of previously disclosed matters and new issues arising during the period covered by, and subsequent to, the dates of Dominion’s and Virginia Power’s Consolidated Financial Statements that may impact the Companies’ future results of operations, financial condition and/or cash flows. This section should be read in conjunction with Item 1. Business and Future Issues and Other Matters in Item 7. MD&A in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

Environmental Matters

Dominion and Virginia Power are subject to costs resulting from a number of federal, state and local laws and regulations designed to protect human health and the environment. These laws and regulations affect future planning and existing operations. They can result in increased capital, operating and other costs as a result of compliance, remediation, containment and monitoring obligations. See Note 22 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 and Note 15 in this report for additional information on various environmental matters.

Regulatory Matters

See Note 13 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 and Note 12 in this report for additional information on various regulatory matters.

Legal Matters

See Item 3. Legal Proceedings in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 and Notes 12 and 15 and Part II, Item 1. in this report for additional information on various legal matters.

Cove Point Liquefaction Project

Dominion is pursuing a liquefaction project at Cove Point, which would enable the facility to liquefy domestically-produced natural gas and export it as LNG. The project, which is expected to cost between approximately $3.4 billion and $3.8 billion, exclusive of financing costs, will have a name-plate capacity of 5.25 million metric tons per annum of LNG.

In April 2013, Dominion announced it had fully subscribed the marketed capacity of the project with signed 20-year terminal service agreements. Pacific Summit Energy, LLC, a U.S. affiliate of Japanese trading company Sumitomo Corporation, and GAIL Global (USA) LNG LLC, a U.S. affiliate of GAIL (India) Ltd., have each contracted for half of the marketed capacity. Dominion also announced it had awarded its engineering, procurement and construction contract for new liquefaction facilities to IHI/Kiewit Cove Point, a joint venture between IHI E&C International Corporation and Kiewit Energy Company, following completion of the front-end engineering and design work.

PAGE65

In April 2013, Cove Point filed with FERC for permission to build liquefaction and other facilities related to the export of natural gas. Also in April 2013, Cove Point filed an application with the Maryland Commission for a certificate of public convenience and necessity to authorize the construction of an electric generating station needed to power the proposed liquefaction equipment. Following receipt of regulatory and other approvals, construction of liquefaction facilities could begin in 2014 with an in-service date in 2017.

Cove Point has historically operated as an LNG import facility, under various long-term import contracts. Since 2010, Dominion has renegotiated certain existing LNG import contracts in a manner that will result in a significant reduction in pipeline and storage capacity utilization and associated anticipated revenues during the period from 2017 through 2028. Such amendments created the opportunity for Dominion to explore the Cove Point liquefaction project, which, assuming it becomes operational, will extend the economic life of Cove Point and contribute to Dominion’s overall growth plan. In total, these renegotiations reduced expected annual revenues from the import-related contracts by approximately $150 million annually from 2017 through 2028, partially offset by approximately $50 million of additional revenues in the years 2013 through 2017.

Dominion is party to an agreement with the Sierra Club restricting activities on portions of the Cove Point property. In May 2012, in response to claims by the Sierra Club, Cove Point filed a complaint for declaratory judgment with the Circuit Court for Calvert County, Maryland to confirm its right to construct the project. In January 2013, the Circuit Court issued a declaratory judgment confirming Cove Point’s right to build liquefaction facilities. In February 2013, the Sierra Club filed a notice of appeal with the Maryland Court of Special Appeals, the intermediate appellate court in Maryland, seeking review of the circuit court’s ruling. In March 2013, Cove Point filed a petition with the Maryland Court of Appeals, the highest appellate court in Maryland, requesting that the Court of Appeals take the appeal directly thus bypassing the intermediate appellate court. Dominion believes that the agreement with the Sierra Club permits it to locate, construct and operate a liquefaction plant at the Cove Point facility.

North Anna 3

Virginia Power is considering the construction of a third nuclear unit at a site located at North Anna. In April 2013, Virginia Power decided to replace the reactor design previously selected for a potential unit with ESBWR technology.

If Virginia Power decides to build a new unit, it must first receive a COL from the NRC, the approval of the Virginia Commission and certain environmental permits and other approvals. Virginia Power expects to amend its COL application to reflect the ESBWR technology by the end of 2013 and expects to receive the COL no earlier than late 2015. Virginia Power has not yet committed to building a new nuclear unit at North Anna.

ITEM 3.

QUANTITATIVE AND QUALITATIVE

DISCLOSURES ABOUT MARKET RISK

The matters discussed in this Item may contain “forward-looking statements” as described in the introductory paragraphs under Part I, Item 2. MD&A of this Form 10-Q. The reader’s attention is directed to those paragraphs for discussion of various risks and uncertainties that may impact Dominion and Virginia Power.

Market Risk Sensitive Instruments and Risk Management

Dominion’s and Virginia Power’s financial instruments, commodity contracts and related financial derivative instruments are exposed to potential losses due to adverse changes in commodity prices, interest rates and equity security prices as described below. Commodity price risk is present in Dominion’s and Virginia Power’s electric operations, Dominion’s gas procurement operations, and Dominion’s energy marketing and trading operations due to the exposure to market shifts in prices received and paid for electricity, natural gas and other commodities. The Companies use commodity derivative contracts to manage price risk exposures for these operations. Interest rate risk is generally related to their outstanding debt. In addition, they are exposed to investment price risk through various portfolios of equity and debt securities.

The following sensitivity analysis estimates the potential loss of future earnings or fair value from market risk sensitive instruments over a selected time period due to a 10% unfavorable change in commodity prices or interest rates.

Commodity Price Risk

To manage price risk, Dominion and Virginia Power primarily hold commodity-based financial derivative instruments for non-trading purposes associated with purchases and sales of electricity, natural gas and other energy-related products. As part of its strategy to market energy and to manage related risks, Dominion also holds commodity-based financial derivative instruments for trading purposes.

PAGE66

The derivatives used to manage commodity price risk are executed within established policies and procedures and may include instruments such as futures, forwards, swaps, options and FTRs that are sensitive to changes in the related commodity prices. For sensitivity analysis purposes, the hypothetical change in market prices of commodity-based financial derivative instruments is determined based on models that consider the market prices of commodities in future periods, the volatility of the market prices in each period, as well as the time value factors of the derivative instruments. Prices and volatility are principally determined based on observable market prices.

A hypothetical 10% unfavorable change in commodity prices of Dominion’s non-trading commodity-based financial derivative instruments would have resulted in a decrease in fair value of approximately $152 million and $128 million as of March 31, 2013 and December 31, 2012, respectively. A hypothetical 10% unfavorable change in commodity prices of Dominion’s commodity-based financial derivative instruments held for trading purposes would have resulted in a decrease in fair value of approximately $7 million and $18 million as of March 31, 2013 and December 31, 2012, respectively.

A hypothetical 10% unfavorable change in commodity prices would not have resulted in a material change in the fair value of Virginia Power’s non-trading commodity-based financial derivatives as of March 31, 2013 or December 31, 2012.

The impact of a change in energy commodity prices on Dominion’s and Virginia Power’s non-trading commodity-based financial derivative instruments at a point in time is not necessarily representative of the results that will be realized when the contracts are ultimately settled. Net losses from commodity derivative instruments used for hedging purposes, to the extent realized, will generally be offset by recognition of the hedged transaction, such as revenue from physical sales of the commodity.

Interest Rate Risk

Dominion and Virginia Power manage their interest rate risk exposure predominantly by maintaining a balance of fixed and variable rate debt. They also enter into interest rate sensitive derivatives, including interest rate swaps and interest rate lock agreements. For variable rate debt and interest rate swaps designated under fair value hedging and outstanding for Dominion and Virginia Power, a hypothetical 10% increase in market interest rates would not have resulted in a material change in earnings at March 31, 2013 or December 31, 2012.

Dominion and Virginia Power may also use forward-starting interest rate swaps and interest rate lock agreements as anticipatory hedges. As of March 31, 2013, Dominion and Virginia Power had $1.3 billion and $250 million, respectively, in aggregate notional amounts of these interest rate derivatives outstanding. A hypothetical 10% decrease in market interest rates would have resulted in a decrease of approximately $14 million and $3 million, respectively, in the fair value of Dominion’s and Virginia Power’s interest rate derivatives at March 31, 2013.

The impact of a change in interest rates on Dominion’s and Virginia Power’s interest rate-based financial derivative instruments at a point in time is not necessarily representative of the results that will be realized when the contracts are ultimately settled. Net gains and/or losses from interest rate derivative instruments used for hedging purposes, to the extent realized, will generally be offset by recognition of the hedged transaction.

Investment Price Risk

Dominion and Virginia Power are subject to investment price risk due to securities held as investments in nuclear decommissioning and rabbi trust funds that are managed by third-party investment managers. These trust funds primarily hold marketable securities that are reported in the Consolidated Balance Sheets at fair value.

Dominion recognized net realized gains (including investment income) on nuclear decommissioning and rabbi trust investments of $69 million, $41 million and $126 million for the three months ended March 31, 2013 and 2012 and for the year ended December 31, 2012, respectively. Net realized gains and losses include gains and losses from the sale of investments as well as any other-than-temporary declines in fair value. Dominion recorded, in AOCI and regulatory liabilities, a net increase in unrealized gains on these investments of $146 million, $196 million and $210 million for the three months ended March 31, 2013 and 2012 and for the year ended December 31, 2012, respectively.

Virginia Power recognized net realized gains (including investment income) on nuclear decommissioning trust investments of $18 million, $17 million and $53 million for the three months ended March 31, 2013 and 2012 and for the year ended December 31, 2012, respectively. Net realized gains and losses include gains and losses from the sale of investments as well as any other-than-temporary declines in fair value. Virginia Power recorded, in AOCI and regulatory liabilities, a net increase in unrealized gains on these investments of $75 million, $79 million and $89 million for the three months ended March 31, 2013 and 2012 and for the year ended December 31, 2012, respectively.

PAGE67

Dominion sponsors pension and other postretirement employee benefit plans that hold investments in trusts to fund employee benefit payments. Virginia Power employees participate in these plans. If the values of investments held in these trusts decline, it will result in future increases in the periodic cost recognized for such employee benefit plans and will be included in the determination of the amount of contributions to be made to the employee benefit plans.

ITEM 4. CONTROLS AND PROCEDURES

Senior management of each of Dominion and Virginia Power, including Dominion’s and Virginia Power’s CEO and CFO, evaluated the effectiveness of each of their respective Companies’ disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation process, each of Dominion’s and Virginia Power’s CEO and CFO have concluded that each of their respective Companies’ disclosure controls and procedures are effective.

There were no changes in either Dominion’s or Virginia Power’s internal control over financial reporting that occurred during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, either of the Companies’ internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, Dominion and Virginia Power are alleged to be in violation or in default under orders, statutes, rules or regulations relating to the environment, compliance plans imposed upon or agreed to by the Companies, or permits issued by various local, state and/or federal agencies for the construction or operation of facilities. Administrative proceedings may also be pending on these matters. In addition, in the ordinary course of business, the Companies and their subsidiaries are involved in various legal proceedings. Other than the matter discussed below, there have been no material changes to the legal proceedings reported in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

In February 2008, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA concerning historical operating changes and capital improvements undertaken at State Line and Kincaid. In April 2009, Dominion received a second request for information. Also in April 2009, Dominion received a Notice and Finding of Violations from the EPA claiming violations of the CAA New Source Review requirements, NSPS, the Title V permit program and the stations’ respective State Implementation Plans. In May 2010, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA concerning historical operating changes and capital improvements undertaken at Brayton Point.

Dominion believes that it complied with applicable laws and the EPA regulations and interpretations in effect at the time the work in question took place. Dominion entered into settlement discussions with the U.S. government and reached an agreement to settle the allegations. In April 2013, the U.S. government lodged a consent decree and complaint with the U.S. District Court for the Central District of Illinois that resolves all alleged violations at State Line, Kincaid and Brayton Point. The settlement mandates the closure of State Line, installation of certain control technology at Kincaid and Brayton Point, the achievement of certain emissions limitations, payment of a civil penalty of $3 million and funding of $10 million in environmental mitigation projects. The consent decree will undergo a 30-day public comment period and is expected to be entered by the court thereafter. Dominion previously accrued a liability of $13 million related to this matter. State Line ceased operations in March 2012 and was sold in June 2012. The installation of pollution control technology is in progress at Kincaid and has been completed at Brayton Point. While Dominion has agreed to sell Kincaid and Brayton Point, under the terms of the sale transaction Dominion will retain the $13 million liability associated with the settlement agreement.

See the following for discussions on various environmental and other regulatory proceedings to which the Companies are parties:

• Notes 13 and 22 to the Consolidated Financial Statements and Future Issues and Other Matters in MD&A in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

• Notes 12 and 15 to the Consolidated Financial Statements in this report.

ITEM 1A. RISK FACTORS

Dominion’s and Virginia Power’s businesses are influenced by many factors that are difficult to predict, involve uncertainties that may materially affect actual results and are often beyond the Companies’ control. A number of these risk factors have been identified in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, which should be taken into consideration when reviewing the information contained in this report. Other than the risk factor discussed below, there have been no material changes with regard to the risk factors previously disclosed in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012. For other factors that may cause actual results to differ materially from those indicated in any forward-looking statement or projection contained in this report, see Forward-Looking Statements in MD&A.

PAGE68

The development, construction and operation of the Cove Point liquefaction project would involve significant risks. As described in greater detail in Future Issues and Other Matters, Dominion intends to invest significant financial resources in the liquefaction project. An inability to obtain financing or otherwise provide liquidity for the project on acceptable terms could negatively affect Dominion’s financial condition, cash flows, the project’s anticipated financial results and/or impair Dominion’s ability to execute the business plan for the project as scheduled.

The project remains subject to DOE, FERC and other approvals. If Dominion receives DOE authorization to export LNG to non-free trade agreement countries, such authorization would be subject to review and possible withdrawal should the DOE conclude that such export authorization is no longer in the public interest, which could have a material adverse effect on the construction or operation of the facility. In addition, the project has been the subject of litigation which, although decided in Dominion’s favor, is the subject of an appeal.

There is no recent industry experience in the U.S. regarding the construction or operation of large liquefaction projects. The construction of the facility is expected to take several years, will be confined within a limited geographic area and could be subject to delays, cost overruns, labor disputes and other factors that could cause the total cost of the project to exceed the anticipated amount and adversely affect Dominion’s financial performance and/or impair Dominion’s ability to execute the business plan for the project as scheduled.

There are significant customer risks associated with the project. The terminal service agreements are subject to certain conditions precedent, including receipt of regulatory approvals. Dominion will also be exposed to counterparty credit risk. While the counterparties’ obligations are supported by parental guarantees and letters of credit, there is no assurance that such credit support would be sufficient to satisfy the obligations in the event of a counterparty default. In addition, if a controversy arises under either agreement resulting in a judgment in Dominion’s favor, Dominion may need to seek to enforce a final U.S. court judgment in a foreign tribunal, which could involve a lengthy process.

Significant Accounting Policies

As permitted by the rules and regulations of the SEC, Dominion’s and Virginia Power’s accompanying unaudited Consolidated Financial Statements contain certain condensed financial information and exclude certain footnote disclosures normally included in annual audited consolidated financial statements prepared in accordance with GAAP. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012.

In Dominion’s and Virginia Power’s opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position as of March 31, 2013, and their results of operations and cash flows for the three months ended March 31, 2013 and 2012. Such adjustments are normal and recurring in nature unless otherwise noted.

The Companies make certain estimates and assumptions in preparing their Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from those estimates.

Dominion’s and Virginia Power’s accompanying unaudited Consolidated Financial Statements include, after eliminating intercompany transactions and balances, their accounts and those of their respective majority-owned subsidiaries and those VIEs where Dominion has been determined to be the primary beneficiary.

The results of operations for interim periods are not necessarily indicative of the results expected for the full year. Information for quarterly periods is affected by seasonal variations in sales, rate changes, electric fuel and other energy-related purchases, purchased gas expenses and other factors.

Certain amounts in Dominion’s and Virginia Power’s 2012 Consolidated Financial Statements and Notes have been reclassified to conform to the 2013 presentation for comparative purposes. The reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows.

Amounts disclosed for Dominion are inclusive of Virginia Power, where applicable.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

As a result of issues generated in the ordinary course of business, Dominion and Virginia Power are involved in legal proceedings before various courts and are periodically subject to governmental examinations (including by regulatory authorities), inquiries and investigations. Certain legal proceedings and governmental examinations involve demands for unspecified amounts of damages, are in an initial procedural phase, involve uncertainty as to the outcome of pending appeals or motions, or involve significant factual issues that need to be resolved, such that it is not possible for the Companies to estimate a range of possible loss. For such matters that the Companies cannot estimate, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the litigation or investigative processes such that the Companies are able to estimate a range of possible loss. For legal proceedings and governmental examinations for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Estimated ranges of loss are inclusive of legal fees and net of any anticipated insurance recoveries. This estimated range is based on currently available information and involves elements of judgment and significant uncertainties. This estimated range of possible loss may not represent the Companies' maximum possible loss exposure. The circumstances of such legal proceedings and governmental examinations will change from time to time and actual results may vary significantly from the current estimate. For current proceedings not specifically reported below, management does not anticipate that the liabilities, if any, arising from such proceedings would have a material effect on Dominion's or Virginia Power's financial position, liquidity or results of operations.

Environmental Matters

Dominion and Virginia Power are subject to costs resulting from a number of federal, state and local laws and regulations designed to protect human health and the environment. These laws and regulations affect future planning and existing operations. They can result in increased capital, operating and other costs as a result of compliance, remediation, containment and monitoring obligations.

Air

The CAA, as amended, is a comprehensive program utilizing a broad range of regulatory tools to protect and preserve the nation's air quality. At a minimum, states are required to establish regulatory programs to address all requirements of the CAA. However, states may choose to develop regulatory programs that are more restrictive. Many of Dominion's and Virginia Power's facilities are subject to the CAA's permitting and other requirements.

The EPA established CAIR with the intent to require significant reductions in SO₂ and NO_X emissions from electric generating facilities. In July 2008, the U.S. Court of Appeals for the D.C. Circuit issued a ruling vacating CAIR. In December 2008, the Court denied rehearing, but also issued a decision to remand CAIR to the EPA. In July 2011, the EPA issued a replacement rule for CAIR, called CSAPR, that required 28 states to reduce power plant emissions that cross state lines. CSAPR established new SO₂ and NO_x emissions cap and trade programs that were completely independent of the current ARP. Specifically, CSAPR required reductions in SO₂ and NO_x emissions from fossil fuel-fired electric generating units of 25 MW or more through annual NO_x emissions caps, NO_x emissions caps during the ozone season (May 1 through September 30) and annual SO₂ emission caps with differing requirements for two groups of affected states.

Following numerous petitions by industry participants for review and motions for stay, the U.S. Court of Appeals for the D.C. Circuit issued a ruling in December 2011 to stay CSAPR pending judicial review. In February and June 2012, the EPA issued technical revisions to CSAPR that are not material to Dominion. In August 2012, the Court vacated CSAPR in its entirety and ordered the EPA to implement CAIR until a valid replacement rule is issued. In October 2012, the EPA filed a petition requesting a rehearing of the court's decision, which was denied in January 2013. The mandate vacating CSAPR was issued in February 2013. In March 2013, the EPA and several environmental groups filed petitions with the U.S. Supreme Court requesting review of the decision to vacate and remand CSAPR. With respect to Dominion's generation fleet, the cost to comply with CAIR is not expected to be material. Future outcomes of litigation and/or any additional action to issue a revised rule could affect the assessment regarding cost of compliance.

In May 2012, the EPA issued final designations for the 75-ppb ozone air quality standard. Several Dominion electric generating facilities are located in areas impacted by this standard. As part of the standard, states will be required to develop and implement plans to address sources emitting pollutants which contribute to the formation of ozone. Until the states have developed implementation plans, Dominion is unable to predict whether or to what extent the new rules will ultimately require additional controls.

In February 2008, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA. The request concerns historical operating changes and capital improvements undertaken at State Line and Kincaid. In April 2009, Dominion received a second request for information. Dominion provided information in response to both requests. Also in April 2009, Dominion received a Notice and Finding of Violations from the EPA claiming violations of the CAA New Source Review requirements, NSPS, the Title V permit program and the stations' respective State Implementation Plans. In May 2010, Dominion received a request for information pursuant to Section 114 of the CAA from the EPA. The request concerns historical operating changes and capital improvements undertaken at Brayton Point.

Dominion believes that it complied with applicable laws and the EPA regulations and interpretations in effect at the time the work in question took place. Dominion entered into settlement discussions with the U.S. government and reached an agreement to settle the allegations. In April 2013, the U.S. government lodged a consent decree and complaint with the U.S. District Court for the Central District of Illinois that resolves all alleged violations at State Line, Kincaid and Brayton Point. The settlement mandates the closure of State Line, installation of certain control technology at Kincaid and Brayton Point, the achievement of certain emissions limitations, payment of a civil penalty of $3 million and funding of $10 million in environmental mitigation projects. The consent decree will undergo a 30-day public comment period and is expected to be entered by the court thereafter. Dominion previously accrued a liability of $13 million related to this matter.  State Line ceased operations in March 2012 and was sold in June 2012.  The installation of pollution control technology is in progress at Kincaid and has been completed at Brayton Point. While Dominion has agreed to sell Kincaid and Brayton Point, under the terms of the sale transaction Dominion will retain the $13 million liability associated with the settlement agreement.

Water

The CWA, as amended, is a comprehensive program requiring a broad range of regulatory tools including a permit program to authorize and regulate discharges to surface waters with strong enforcement mechanisms. Dominion and Virginia Power must comply with all aspects of the CWA programs at their operating facilities.

In September 2010, Millstone's NPDES permit was reissued under the CWA. The conditions of the permit require an evaluation of control technologies that could result in additional expenditures in the future. The report summarizing the results of the evaluation was submitted in August 2012 and is under review by the Connecticut Department of Energy and Environmental Protection. Dominion cannot currently predict the outcome of this review. In October 2010, the permit issuance was appealed to the state court by a private plaintiff. The permit is expected to remain in effect during the appeal. Dominion is currently unable to make an estimate of the potential financial statement impacts related to this matter.

Solid and Hazardous Waste

The CERCLA, as amended, provides for immediate response and removal actions coordinated by the EPA in the event of threatened releases of hazardous substances into the environment and authorizes the U.S. government either to clean up sites at which hazardous substances have created actual or potential environmental hazards or to order persons responsible for the situation to do so. Under the CERCLA, as amended, generators and transporters of hazardous substances, as well as past and present owners and operators of contaminated sites, can be jointly, severally and strictly liable for the cost of cleanup. These potentially responsible parties can be ordered to perform a cleanup, be sued for costs associated with an EPA-directed cleanup, voluntarily settle with the U.S. government concerning their liability for cleanup costs, or voluntarily begin a site investigation and site remediation under state oversight.

From time to time, Dominion or Virginia Power may be identified as a potentially responsible party to a Superfund site. The EPA (or a state) can either allow such a party to conduct and pay for a remedial investigation, feasibility study and remedial action or conduct the remedial investigation and action itself and then seek reimbursement from the potentially responsible parties. Each party can be held jointly, severally and strictly liable for the cleanup costs. These parties can also bring contribution actions against each other and seek reimbursement from their insurance companies. As a result, Dominion or Virginia Power may be responsible for the costs of remedial investigation and actions under the Superfund law or other laws or regulations regarding the remediation of waste. Except as noted below, the Companies do not believe this will have a material effect on results of operations, financial condition and/or cash flows.

In September 2011, the EPA issued a UAO to Virginia Power and 22 other parties, ordering specific remedial action of certain areas at the Ward Transformer Superfund site located in Raleigh, North Carolina. Virginia Power does not believe it is a liable party under CERCLA based on its alleged connection to the site. In November 2011, Virginia Power and a number of other parties notified the EPA that they are declining to undertake the work set forth in the UAO.

The EPA may seek to enforce a UAO in court pursuant to its enforcement authority under CERCLA, and may seek recovery of its costs in undertaking removal or remedial action. If the court determines that a respondent failed to comply with the UAO without sufficient cause, the EPA may also seek civil penalties of up to $37,500 per day for the violation and punitive damages of up to three times the costs incurred by the EPA as a result of the party's failure to comply with the UAO. Virginia Power is currently unable to make an estimate of the potential financial statement impacts related to the Ward Transformer matter.

Dominion has determined that it is associated with 17 former manufactured gas plant sites, three of which pertain to Virginia Power. Studies conducted by other utilities at their former manufactured gas plant sites have indicated that those sites contain coal tar and other potentially harmful materials. None of the former sites with which Dominion and Virginia Power are associated is under investigation by any state or federal environmental agency. At one of the former sites, Dominion is conducting a state-approved post closure groundwater monitoring program and an environmental land use restriction has been recorded. Another site has been accepted into a state-based voluntary remediation program. Dominion is currently evaluating the nature and extent of the contamination from this site as well as potential remedial options, but is not yet able to estimate the future remediation costs. Due to the uncertainty surrounding these sites, Dominion is unable to make an estimate of the potential financial statement impacts related to these sites.

Climate Change Legislation and Regulation

Massachusetts, Rhode Island and Connecticut, among other states, have joined RGGI, a multi-state effort to reduce CO₂ emissions in the Northeast implemented through state specific regulations. Under the initiative, aggregate CO₂ emissions from power plants in participating states are required to be stabilized at current levels from 2009 to 2015. Further reductions from current levels would be required to be phased in starting in 2016 such that by 2019 there would be a 10% reduction in participating state power plant CO₂ emissions. During 2012, RGGI underwent a program review, and in February 2013, revisions to the RGGI model rule were issued.  Dominion is in the process of evaluating these revisions as to potential impacts on Dominion's fossil fired generation operations in RGGI states.  Until this evaluation is completed, Dominion is unable to estimate the potential financial statement impacts related to the program review.

Nuclear Matters

In March 2011, a magnitude 9.0 earthquake and subsequent tsunami caused significant damage at the Fukushima Daiichi nuclear power station in northeast Japan. These events have resulted in significant nuclear safety reviews required by the NRC and industry groups such as INPO. Like other U.S. nuclear operators, Dominion has been gathering supporting data and participating in industry initiatives focused on the ability to respond to and mitigate the consequences of design-basis and beyond-design-basis events at its stations. 

In July 2011, an NRC task force provided initial recommendations based on its review of the Fukushima Daiichi accident and in October 2011 the NRC staff prioritized these recommendations into Tiers 1, 2 and 3, with the Tier 1 recommendations consisting of actions which the staff determined should be started without unnecessary delay. In December 2011, the NRC Commissioners approved the agency staff's prioritization and recommendations; and that same month an appropriations act directed the NRC to require reevaluation of external hazards (not limited to seismic and flooding hazards) as soon as possible.

Based on the prioritized recommendations, in March 2012, the NRC issued orders and information requests requiring specific reviews and actions to all operating reactors, construction permit holders and combined license holders based on the lessons learned from the Fukushima Daiichi event. The orders applicable to Dominion require implementation of safety enhancements related to mitigation strategies to respond to extreme natural events resulting in the loss of power at plants, and enhancing spent fuel pool instrumentation. The orders require prompt implementation of the safety enhancements and completion of implementation within two refueling outages or by December 31, 2016, whichever comes first. The information requests issued by the NRC request each reactor to reevaluate the seismic and flooding hazards at their site using present-day methods and information, conduct walkdowns of their facilities to ensure protection against the hazards in their current design basis, and to reevaluate their emergency communications systems and staffing levels. Dominion and Virginia Power do not currently expect that compliance with the NRC's March 2012 orders and information requests will materially impact their financial position, results of operations or cash flows during the approximately four-year implementation period. The NRC staff is evaluating the implementation of the longer term Tier 2 and Tier 3 recommendations. Dominion and Virginia Power are currently unable to estimate the potential financial impacts related to compliance with Tier 2 and Tier 3 recommendations.

Guarantees

Dominion

At March 31, 2013, Dominion had issued $89 million of guarantees, primarily to support equity method investees. No significant amounts related to these guarantees have been recorded. As of March 31, 2013, Dominion’s exposure under these guarantees was $59 million, primarily related to certain reserve requirements associated with non-recourse financing.

In addition to the above guarantees, Dominion and its partners, Shell and BP, may be required to make additional periodic equity contributions to NedPower and Fowler Ridge in connection with certain funding requirements associated with their respective non-recourse financings. As of March 31, 2013, Dominion's maximum remaining cumulative exposure under these equity funding agreements is $98 million through 2019 and its maximum annual future contributions could range from approximately $4 million to $19 million.

Dominion also enters into guarantee arrangements on behalf of its consolidated subsidiaries, primarily to facilitate their commercial transactions with third parties. To the extent that a liability subject to a guarantee has been incurred by one of Dominion's consolidated subsidiaries, that liability is included in the Consolidated Financial Statements. Dominion is not required to recognize liabilities for guarantees issued on behalf of its subsidiaries unless it becomes probable that it will have to perform under the guarantees. Terms of the guarantees typically end once obligations have been paid. Dominion currently believes it is unlikely that it would be required to perform or otherwise incur any losses associated with guarantees of its subsidiaries' obligations.

At March 31, 2013, Dominion had issued the following subsidiary guarantees:

	Stated Limit		Value(1)
(millions)
Subsidiary debt(2)	$	363	$	363
Commodity transactions(3)	3,019		341
Nuclear obligations(4)	232		51
Other(5)	638		108
Total	$	4,252	$	863

(1) Represents the estimated portion of the guarantee's stated limit that is utilized as of March 31, 2013 based upon prevailing economic conditions and fact patterns specific to each guarantee arrangement. For those guarantees related to obligations that are recorded as liabilities by Dominion's subsidiaries, the value includes the recorded amount.

(2) Guarantees of debt of certain DEI subsidiaries. In the event of default by the subsidiaries, Dominion would be obligated to repay such amounts.

(3) Guarantees related to energy trading and marketing activities and other commodity commitments of certain subsidiaries, including subsidiaries of Virginia Power and DEI. These guarantees were provided to counterparties in order to facilitate physical and financial transactions in gas, oil, electricity, pipeline capacity, transportation and related commodities and services. If any of these subsidiaries fail to perform or pay under the contracts and the counterparties seek performance or payment, Dominion would be obligated to satisfy such obligation. Dominion and its subsidiaries receive similar guarantees as collateral for credit extended to others. The value provided includes certain guarantees that do not have stated limits.

(4) Guarantees related to certain DEI subsidiaries' potential retrospective premiums that could be assessed if there is a nuclear incident under Dominion's nuclear insurance programs and guarantees for a DEI subsidiary's and Virginia Power's commitment to buy nuclear fuel. Excludes Dominion's agreement to provide up to $150 million and $60 million to two DEI subsidiaries to pay the operating expenses of Millstone and Kewaunee, respectively, in the event of a prolonged outage, as part of satisfying certain NRC requirements concerned with ensuring adequate funding for the operations of nuclear power stations. The agreement for Kewaunee also provides for funds through the completion of decommissioning.

(5) Guarantees related to other miscellaneous contractual obligations such as leases, environmental obligations and construction projects. Also includes guarantees related to certain DEI subsidiaries' obligations for equity capital contributions and energy generation associated with Fowler Ridge and NedPower.

In April 2013, Dominion entered into guarantee arrangements on behalf of Cove Point to facilitate the liquefaction project.  These agreements include guarantees supporting the terminal services and transportation agreements as well as the engineering, procurement and construction contract for the new liquefaction facilities. Two of the guarantees have no stated limit, one guarantee has a $150 million limit, and one guarantee has a $1.75 billion aggregate limit with an annual draw limit of $175 million.

Surety Bonds and Letters of Credit

As of March 31, 2013, Dominion had purchased $150 million of surety bonds, including $56 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $19 million, including $2 million at Virginia Power, to facilitate commercial transactions by its subsidiaries with third parties. Under the terms of surety bonds, the Companies are obligated to indemnify the respective surety bond company for any amounts paid.

Dominion's effective tax rate in 2012 reflects a $20 million reduction of valuation allowance related to state operating loss carryforwards attributable to Fairless. After considering the results of Fairless' operations in recent years and a forecast of future operating results reflecting Dominion's planned purchase of the facility, Dominion concluded that it was more likely than not that the tax benefit of the operating losses would be realized. Significant assumptions included future commodity prices, in particular, those for electric energy produced by Fairless and those for natural gas, as compared to other fuels used for the generation of electricity, which would significantly influence the extent to which Fairless is dispatched by PJM.

As of March 31, 2013, there have been no material changes in Dominion's and Virginia Power's unrecognized tax benefits or possible changes that could reasonably be expected to occur during the next twelve months. See Note 5 to the Consolidated Financial Statements in Dominion's and Virginia Power's Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of these unrecognized tax benefits.

Credit Risk

Credit Risk

Dominion’s and Virginia Power’s accounting policies for credit risk are discussed in Note 23 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012.

At March 31, 2013, Dominion's gross credit exposure totaled $552 million. After the application of collateral, credit exposure was reduced to $551 million. Of this amount, investment grade counterparties, including those internally rated, represented 80%. One counterparty exposure represented 10% of Dominion's total exposure and is a utility holding company rated investment grade. At March 31, 2013, Virginia Power's exposure to potential concentrations of credit risk was not material.

Credit-Related Contingent Provisions

The majority of Dominion's derivative instruments contain credit-related contingent provisions. These provisions require Dominion to provide collateral upon the occurrence of specific events, primarily a credit rating downgrade. If the credit-related contingent features underlying these instruments that are in a liability position and not fully collateralized with cash were fully triggered as of March 31, 2013 and December 31, 2012, Dominion would have been required to post an additional $58 million and $110 million, respectively, of collateral to its counterparties. The collateral that would be required to be posted includes the impacts of any offsetting asset positions and any amounts already posted for derivatives, non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. Dominion had posted $9 million in collateral at March 31, 2013 and $4 million in collateral at December 31, 2012, related to derivatives with credit-related contingent provisions that are in a liability position and not fully collateralized with cash. The collateral posted includes any amounts paid related to non-derivative contracts and derivatives elected under the normal purchases and normal sales exception, per contractual terms. The aggregate fair value of all derivative instruments with credit-related contingent provisions that are in a liability position and not fully collateralized with cash as of March 31, 2013 and December 31, 2012 was $108 million and $163 million, respectively, which does not include the impact of any offsetting asset positions. Credit-related contingent provisions for Virginia Power were not material as of March 31, 2013 and December 31, 2012. See Note 9 for further information about derivative instruments.

Regulatory Matters

Regulatory Matters Involving Potential Loss Contingencies

As a result of issues generated in the ordinary course of business, Dominion and Virginia Power are involved in various regulatory matters. Certain regulatory matters may ultimately result in a loss; however, as such matters are in an initial procedural phase, involve uncertainty as to the outcome of pending reviews or orders, and/or involve significant factual issues that need to be resolved, it is not possible for the Companies to estimate a range of possible loss. For matters for which the Companies cannot estimate a range of possible loss, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the regulatory process such that the Companies are able to estimate a range of possible loss. For regulatory matters for which the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. This estimated range is based on currently available information and involves elements of judgment and significant uncertainties. This estimated range of possible loss may not represent the Companies' maximum possible loss exposure. The circumstances of such regulatory matters will change from time to time and actual results may vary significantly from the current estimate. For current matters not specifically reported below, management does not anticipate that the outcome from such matters would have a material effect on Dominion's or Virginia Power's financial position, liquidity or results of operations.

FERC - Electric

Under the Federal Power Act, FERC regulates wholesale sales and transmission of electricity in interstate commerce by public utilities. Virginia Power purchases and sells electricity in the PJM wholesale market and Dominion's merchant generators sell electricity in the PJM, MISO and ISO-NE wholesale markets under Dominion's market-based sales tariffs authorized by FERC. In addition, Virginia Power has FERC approval of a tariff to sell wholesale power at capped rates based on its embedded cost of generation. This cost-based sales tariff could be used to sell to loads within or outside Virginia Power's service territory. Any such sales would be voluntary.

Rates

In April 2008, FERC granted an application for Virginia Power's electric transmission operations to establish a forward-looking formula rate mechanism that updates transmission rates on an annual basis and approved an ROE of 11.4%, effective as of January 1, 2008. The formula rate is designed to recover the expected revenue requirement for each calendar year and is updated based on actual costs. The FERC-approved formula method, which is based on projected costs, allows Virginia Power to earn a current return on its growing investment in electric transmission infrastructure.

In July 2008, Virginia Power filed an application with FERC requesting a revision to its revenue requirement to reflect an additional ROE incentive adder for eleven electric transmission enhancement projects. Under the proposal, the cost of transmission service would increase to include an ROE incentive adder for each of the eleven projects, beginning the date each project enters commercial operation (but not before January 1, 2009). Virginia Power proposed an incentive of 1.5% for four of the projects (including the Meadow Brook-to-Loudoun and Carson-to-Suffolk lines, which were completed in 2011) and an incentive of 1.25% for the other seven projects. In August 2008, FERC approved the proposal, effective September 1, 2008, the incentives were included in the PJM Tariff, and billing for the incentives was made accordingly. In 2012, PJM canceled one of the eleven projects with an estimated cost of $7 million. The total cost for the other ten projects included in Virginia Power's formula rate for 2013 is $852 million and the remaining projects were completed in 2012.  Numerous parties sought rehearing of the FERC order in August 2008, and in May 2012 FERC denied rehearing.  In July 2012, the North Carolina Commission filed an appeal of the FERC orders granting the incentives with the U.S. Court of Appeals for the Fourth Circuit.  Although Virginia Power cannot predict the outcome of the appeal, it is not expected to have a material effect on results of operations.

In March 2010, ODEC and NCEMC filed a complaint with FERC against Virginia Power claiming that approximately $223 million in transmission costs related to specific projects were unjust, unreasonable and unduly discriminatory or preferential and should be excluded from Virginia Power's transmission formula rate. ODEC and NCEMC requested that FERC establish procedures to determine the amount of costs for each applicable project that should be excluded from Virginia Power's rates. In October 2010, FERC issued an order dismissing the complaint in part and established hearings and settlement procedures on the remaining part of the complaint. In February 2012, Virginia Power submitted to FERC a settlement agreement to resolve all issues set for hearing. All transmission customer parties to the proceeding joined the settlement. The Virginia Commission, North Carolina Commission and Public Staff of the North Carolina Commission, while not parties to the settlement, have agreed to not oppose the settlement. The settlement was accepted by FERC in May 2012 and provides for payment by Virginia Power to the transmission customer parties collectively of $250,000 per year for ten years and resolves all matters other than allocation of the incremental cost of certain underground transmission facilities, which has been briefed pursuant to FERC's May 2012 order and awaits FERC action. While Virginia Power cannot predict the outcome of the briefing, it is not expected to have a material effect on results of operations.

Other Regulatory Matters

Other than the following matters, there have been no significant developments regarding the pending regulatory matters disclosed in Note 13 to the Consolidated Financial Statements in Dominion's and Virginia Power's Annual Report on Form 10-K for the year ended December 31, 2012.

Virginia Regulation

2013 Biennial Review

Pursuant to the Regulation Act, in March 2013, Virginia Power submitted its base rate filings and accompanying schedules in support of the 2013 biennial review of its rates, terms and conditions, as well as of its earnings for test years 2011 and 2012. In its filing, Virginia Power did not request an increase in base rates for generation and distribution services, and proposed that base rates remain at their existing level as set by the Virginia Settlement Approval Order. Virginia Power's earnings test analysis, as filed, demonstrates it earned an ROE of 10.11% on its generation and distribution services for the combined test period of 2011 and 2012. The Virginia Commission will determine whether Virginia Power's earnings for the 2011 and 2012 test years, considered as a whole, were within 50 basis points above or below the authorized ROE of 10.9% established in the 2011 biennial review. If Virginia Power's earnings for the test years are determined to be more than 50 basis points above the authorized ROE, the Virginia Commission will order a credit to customers of 60% of the earnings that exceeded an ROE of 11.4% for the biennial period. In such a scenario, the Virginia Commission can also order a reduction in Virginia Power's base rates, but only if the resulting rates will provide Virginia Power with the opportunity to fully recover the costs of providing its services and earn not less than a fair combined rate of return on its distribution and generation services. If Virginia Power's earnings for the test years are determined to be more than 50 basis points below the authorized ROE, the Virginia Commission can order an increase to Virginia Power's rates if such an increase is necessary to provide Virginia Power the opportunity to fully recover the costs of providing services and to earn not less than a fair combined rate of return on its generation and distribution services. The Virginia Commission will also authorize an ROE for Virginia Power that will be applied to Riders R, S, W, B, and C1A and C2A, and that will also be utilized to measure base rate earnings as of January 1, 2013. Virginia Power is requesting authorization of an ROE of 11.5% effective January 1, 2014 through December 31, 2014 based on Virginia Power's current cost of equity and performance. Pursuant to the Regulation Act, Virginia Power's authorized ROE can be no lower than the average of the returns reported for the three previous years by not less than a majority of comparable utilities in the Southeastern U.S., with certain limitations as described in the Regulation Act. A final order in the 2013 biennial review for base rates must be issued no later than November 28, 2013.

DSM Riders C1A and C2A

In April 2013, the Virginia Commission approved revenue requirements for Riders C1A and C2A of approximately $4 million and $23 million, respectively, for the May 1, 2013 to April 30, 2014 rate year.  The Virginia Commission approved a two-year extension of the Residential Low Income Program subject to an approximately $14 million cost cap, as well as a three-year extension of the Residential Air Conditioner Cycling Program.  The Virginia Commission rejected Virginia Power's request for approval of a process whereby the Virginia Commission Staff could administratively approve limited modifications to the designs of previously approved DSM programs.  Virginia Power must file any application to continue Riders C1A and C2A by September 1, 2013.

Generation Rider S

The Virginia Commission previously approved Rider S in conjunction with the Virginia City Hybrid Energy Center. In March 2013, the Virginia Commission approved a revised revenue requirement for Rider S of approximately $248 million for the rate year beginning April 1, 2013, and stated that Virginia Power should file its next Rider S case by June 30, 2013.

Generation Rider B

In 2012, the Virginia Commission approved the conversion of the Altavista, Hopewell, and Southampton power stations to biomass, and in conjunction approved Rider B. In March 2013, the Virginia Commission approved a revenue requirement for the pre-commercial operations date period and the post-commercial operations date period, resulting in an average recovery amount of approximately $12 million for the rate year commencing April 1, 2013.

Solar Distributed Generation Demonstration Program

In March 2013, the Virginia Commission approved Rate Schedule SP, under which Virginia Power will purchase 100% of the energy output from up to a combined 3 MW of customer-owned solar distributed generation facilities, including all environmental attributes and associated renewable energy credits, at a fixed price of $0.15 per kWh for five years. This fixed price has two components: an avoided cost component (including line losses) determined using Virginia Power's Rate Schedule 19 and recovered through Virginia Power's fuel factor, and a voluntary environmental contribution component provided by customers voluntarily participating in Virginia Power's Green Power Program.

Ohio Regulation

In 2008, East Ohio began PIR, aimed at replacing approximately 20% of its pipeline system. In February 2013, East Ohio filed an application with the Ohio Commission to adjust the cost recovery charge for costs associated with PIR investments for the calendar year 2012 and cumulatively. The application includes total gross plant investment for 2012 of $148 million, cumulative gross plant investment of $511 million, and a revenue requirement of $67 million. A stipulation was submitted by East Ohio and the Staff of the Ohio Commission that supports the rates filed by East Ohio.  The Ohio Consumers' Counsel neither supports nor opposes the stipulation and has raised no issues regarding the rates filed. Approval of the application is anticipated in time to implement the resulting cost recovery charges in May 2013.

FERC Gas Regulation

Sabinsville-to-Morrisville Project

In March 2013, FERC approved DTI's Sabinsville-to-Morrisville project and authorized commencement of construction in the second quarter of 2013. The project is expected to have capacity of approximately 92,000 Dths per day, which will be leased by TGP to move additional Marcellus supplies from a TGP pipeline in northeast Pennsylvania to a DTI line in upstate New York. The project is expected to be placed into service in November 2013.

Tioga Area Expansion Project

In March 2013, DTI received FERC approval of the Tioga Area Expansion Project. The project is expected to provide approximately 270,000 Dths per day of firm transportation service from supply interconnects in Tioga and Potter Counties in Pennsylvania to DTI's Crayne interconnect with Transcontinental Gas Pipe Line Company in Clinton County, Pennsylvania. Construction is expected to commence in April 2013 with an anticipated in-service date of November 2013.

Fair Value Measurements

Fair Value Measurements

Dominion's and Virginia Power's fair value measurements are made in accordance with the policies discussed in Note 6 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012. See Note 9 in this report for further information about their derivatives and hedge accounting activities.

Dominion and Virginia Power enter into certain physical and financial forwards and futures, options, and full requirements contracts, which are considered Level 3 as they have one or more inputs that are not observable and are significant to the valuation. The discounted cash flow method is used to value Level 3 physical and financial forwards, futures, and full requirements contracts. An option model is used to value Level 3 physical and financial options. The discounted cash flow model for forwards and futures calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return, and credit spreads. Full requirements contracts add load shaping and usage factors in addition to the discounted cash flow model inputs. The option model calculates mark-to-market valuations using variations of the Black-Scholes option model. The inputs into the models are the forward market prices, implied price volatilities, mean reversions, risk-free rate of return, the option expiration dates, the option strike prices, price correlations, the original sales prices, and volumes. For Level 3 fair value measurements, the forward market prices, the implied price volatilities, price correlations, load shaping, and usage factors are considered unobservable. The unobservable inputs are developed and substantiated using historical information, available market data, third-party data, and statistical analysis. Periodically, inputs to valuation models are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third-party pricing sources.

The following table presents Dominion's quantitative information about Level 3 fair value measurements. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility, price correlations, load shaping, and usage factors.

Fair Value of Financial Instruments

Substantially all of Dominion’s and Virginia Power’s financial instruments are recorded at fair value, with the exception of the instruments described below that are reported at historical cost. Estimated fair values have been determined using available market information and valuation methodologies considered appropriate by management. The carrying amount of cash and cash equivalents, customer and other receivables, short-term debt and accounts payable are representative of fair value because of the short-term nature of these instruments. For Dominion’s and Virginia Power’s financial instruments that are not recorded at fair value, the carrying amounts and estimated fair values are as follows:

	March 31, 2013				December 31, 2012
	Carrying Amount		Estimated Fair Value(1)		Carrying Amount		Estimated Fair Value(1)
(millions)
Dominion
Long-term debt, including securities due within one year(2)	$	17,097	$	19,874	$	16,841	$	19,898
Securities due within one year, VIE(3)	852		855		860		864
Junior subordinated notes	1,373		1,435		1,373		1,430

Preferred stock(4)	257		260		257		255

(1) Fair value is estimated using market prices, where available, and interest rates currently available for issuance of debt with similar terms and remaining maturities. All fair value measurements are classified as Level 2. The carrying amount of debt issues with short-term maturities and variable rates refinanced at current market rates is a reasonable estimate of their fair value.

(2) Includes amounts which represent the unamortized discount and premium. At March 31, 2013 and December 31, 2012, includes the valuation of certain fair value hedges associated with Dominion’s fixed rate debt of approximately $72 million and $93 million, respectively.

(3) Includes amounts which represent the unamortized premium.

(4) Includes deferred issuance expenses of $2 million at March 31, 2013 and December 31, 2012.

Derivatives and Hedge Accounting Activities

Derivatives and Hedge Accounting Activities

Dominion’s and Virginia Power’s accounting policies and objectives and strategies for using derivative instruments are discussed in Note 2 to the Consolidated Financial Statements in their Annual Report on Form 10-K for the year ended December 31, 2012. See Note 8 in this report for further information about fair value measurements and associated valuation methods for derivatives.

Derivative assets and liabilities are presented gross on Dominion's and Virginia Power's Consolidated Balance Sheets. Dominion's and Virginia Power's derivative contracts include both over-the-counter transactions and those that are executed on an exchange or other trading platform (exchange contracts) and centrally cleared. Over-the-counter contracts are bilateral contracts that are transacted directly with a third party. Exchange contracts utilize a financial intermediary, exchange, or clearinghouse to enter, execute, or clear the transactions. Certain over-the-counter and exchange contracts contain contractual rights of setoff through master netting arrangements, derivative clearing agreements, and contract default provisions. In addition, the contracts are subject to conditional rights of setoff through counterparty nonperformance, insolvency, or other conditions.

In general, most over-the-counter transactions and all exchange contracts are subject to collateral requirements. Types of collateral for over-the-counter and exchange contracts include cash, letters of credit, and in some cases other forms of security, none of which are subject to restrictions. Cash collateral is used in the table below to offset derivative assets and liabilities. Certain accounts receivable and accounts payable recognized on Dominion's and Virginia Power's Consolidated Balance Sheets, as well as letters of credit and other forms of security, all of which are not included in the tables below, are subject to offset under master netting agreements or similar agreements and would reduce the net exposure.

Dominion

The following table presents the volume of Dominion’s derivative activity as of March 31, 2013. These volumes are based on open derivative positions and represent the combined absolute value of their long and short positions, except in the case of offsetting transactions, for which they represent the absolute value of the net volume of their long and short positions.

(1) Includes options.

(2) Includes NGLs and oil.

For the three months ended March 31, 2013 and 2012, gains or losses on hedging instruments determined to be ineffective and amounts excluded from the assessment of effectiveness were not material. Amounts excluded from the assessment of effectiveness include gains or losses attributable to changes in the time value of options and changes in the differences between spot prices and forward prices.

The following table presents selected information related to gains (losses) on cash flow hedges included in AOCI in Dominion’s Consolidated Balance Sheet at March 31, 2013:

	AOCI After-Tax			Amounts Expected to be Reclassified to Earnings during the next 12 Months After-Tax			Maximum Term
(millions)
Commodities:
Gas	$	(20	)	$	(14	)	31 months
Electricity	31			(12		)	33 months
Other	8			4			38 months
Interest rate	(155		)	(27		)	358 months
Total	$	(136	)	$	(49	)

The amounts that will be reclassified from AOCI to earnings will generally be offset by the recognition of the hedged transactions (e.g., anticipated sales) in earnings, thereby achieving the realization of prices contemplated by the underlying risk management strategies and will vary from the expected amounts presented above as a result of changes in market prices and interest rates.

Significant Financing Transactions

Credit Facilities and Short-term Debt

Dominion and Virginia Power use short-term debt to fund working capital requirements and as a bridge to long-term debt financings. The levels of borrowing may vary significantly during the course of the year, depending upon the timing and amount of cash requirements not satisfied by cash from operations. In addition, Dominion utilizes cash and letters of credit to fund collateral requirements. Collateral requirements are impacted by commodity prices, hedging levels, Dominion’s credit ratings and the credit quality of its counterparties.

At March 31, 2013, Dominion’s commercial paper and letters of credit outstanding, as well as capacity available under credit facilities, were as follows:

	Facility Limit		Outstanding Commercial Paper		Outstanding Letters of Credit		Facility Capacity Available
(millions)
Joint revolving credit facility(1)	$	3,000	$	2,003	$	—	$	997
Joint revolving credit facility(2)	500		—		19		481
Total	$	3,500	$	2,003	$	19	$	1,478

(1) This credit facility has a maturity date of September 2017, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion of letters of credit.

(2) The maturity date for $400 million of the $500 million in committed capacity of this credit facility is September 2017. The remaining $100 million has a maturity date of September 2016. This credit facility can be used to support bank borrowings, commercial paper and letter of credit issuances.

Virginia Power’s short-term financing is supported by two joint revolving credit facilities with Dominion. These credit facilities are being used for working capital, as support for the combined commercial paper programs of Dominion and Virginia Power and for other general corporate purposes.

At March 31, 2013, Virginia Power’s share of commercial paper and letters of credit outstanding, as well as its capacity available under its joint credit facilities with Dominion were as follows:

	Facility Sub-limit		Outstanding Commercial Paper		Outstanding Letters of Credit		Facility Sub-limit Capacity Available
(millions)
Joint revolving credit facility(1)	$	1,000	$	661	$	—	$	339
Joint revolving credit facility(2)	250		—		2		248
Total	$	1,250	$	661	$	2	$	587

(1) This credit facility has a maturity date of September 2017, and can be used to support bank borrowings and the issuance of commercial paper, as well as to support up to $1.5 billion (or the sub-limit, whichever is less) of letters of credit. Virginia Power's current sub-limit under this credit facility can be increased or decreased multiple times per year.

(2) The maturity date for $400 million of the $500 million in committed capacity of this credit facility is September 2017. The remaining $100 million has a maturity date of September 2016. This credit facility can be used to support bank borrowings, commercial paper and letter of credit issuances. Virginia Power's current sub-limit under this credit facility can be increased or decreased multiple times per year.

In addition to the credit facility commitments mentioned above, Virginia Power also has a $120 million credit facility with a maturity date of September 2017. This facility supports certain tax-exempt financings of Virginia Power.

Long-term Debt

In January 2013, Virginia Power issued $250 million of 1.2% senior notes and $500 million of 4.0% senior notes that mature in 2018 and 2043, respectively.

In March 2013, Virginia Power issued $500 million of 2.75% senior notes that mature in 2023.

In connection with the expected sale of Kincaid, in April 2013 Kincaid provided notice of redemption for its 7.33% senior secured bonds due June 15, 2020. The bonds are expected to be redeemed in May 2013 for approximately $186 million, including a make-whole premium and accrued interest. At March 31, 2013, the bonds were included in securities due within one year in Dominion's Consolidated Balance Sheet.

In March 2013, Virginia Power redeemed the $50 million2.5% Industrial Development Authority of the Town of Louisa, Virginia Solid Waste and Sewage Disposal Revenue Bonds, Series 2001A, that would have otherwise matured in March 2031.

Convertible Securities

At March 31, 2013, Dominion had $72 million of outstanding contingent convertible senior notes that are convertible by holders into a combination of cash and shares of Dominion’s common stock under certain circumstances. The conversion feature requires that the principal amount of each note be repaid in cash, while amounts payable in excess of the principal amount will be paid in common stock. The conversion rate is subject to adjustment upon certain events such as subdivisions, splits, combinations of common stock or the issuance to all common stock holders of certain common stock rights, warrants or options and certain dividend increases. As of March 31, 2013, the conversion rate had been adjusted, primarily due to individual dividend payments above the level paid at issuance, to 29.5147 shares of common stock per $1,000 principal amount of senior notes, which represents a conversion price of $33.88. If the outstanding notes as of March 31, 2013 were all converted, it would result in the issuance of approximately 900 thousand additional shares.

The senior notes are eligible for conversion during any calendar quarter when the closing price of Dominion’s common stock was equal to or higher than 120% of the conversion price for at least 20 out of the last 30 consecutive trading days of the preceding quarter. During the three months ended March 31, 2013, the senior notes were eligible for conversion and approximately $10 million of the notes were converted by holders. The senior notes are eligible for conversion during the second quarter of 2013.

Junior Subordinated Notes Payable to Affiliated Trusts

In January 2013, Dominion repaid its $258 million7.83% unsecured junior subordinated debentures and redeemed all 250 thousand units of the $250 million7.83% Dominion Resources Capital Trust I capital securities due December 1, 2027. The securities were redeemed at a price of $1,019.58 per capital security plus accrued and unpaid distributions.

In addition to the operating segments above, the Companies also report a Corporate and Other segment.

The Corporate and Other Segment of Dominion includes its corporate, service company and other functions (including unallocated debt) and the net impact of operations that are expected to be or are currently discontinued. In addition, Corporate and Other includes specific items attributable to Dominion's operating segments that are not included in profit measures evaluated by executive management in assessing the segments' performance or allocating resources among the segments.

In the three months ended March 31, 2013, Dominion reported an after-tax net benefit of $19 million for specific items in the Corporate and Other segment, with $17 million of these net benefits attributable to its operating segments. In the three months ended March 31, 2012, Dominion reported after-tax net expense of $3 million for specific items in the Corporate and Other segment, all of which was attributable to its operating segments.

The net benefit for specific items in 2013 primarily related to the impact of the following items:

• A $44 million ($26 million after-tax) net gain on investments held in nuclear decommissioning trust funds, attributable to Dominion Generation; and

• A $1 million net benefit related to Brayton Point and Kincaid, including a $38 million ($23 million after-tax) benefit from the discontinued operations of these merchant power stations partially offset by impairments of $37 million ($22 million after-tax) related to these stations, attributable to Dominion Generation.

The net expense for specific items in 2012 primarily related to the impact of the following items:

• A $22 million ($11 million after-tax) loss from the discontinued operations of Brayton Point and Kincaid, attributable to Dominion Generation; partially offset by

• A $15 million ($9 million after-tax) net gain on investments held in nuclear decommissioning trust funds, attributable to Dominion Generation.

The Corporate and Other Segment of Virginia Power primarily includes specific items attributable to its operating segments that are not included in profit measures evaluated by executive management in assessing the segments' performance or allocating resources among the segments.

Sale of Brayton Point, Kincaid and Equity Method Investment in Elwood

In March 2013, Dominion entered into an agreement with Energy Capital Partners to sell Brayton Point, Kincaid, and its 50% interest in Elwood, which is an equity method investment.

The transaction is expected to close in the second quarter of 2013, subject to FERC approval. The sales price is approximately $472 million, subject to customary closing adjustments. In the first quarter of 2013, Brayton Point's and Kincaid's assets and liabilities to be disposed of were classified as held for sale and adjusted to their estimated fair value less cost to sell, resulting in a pre-tax impairment charge of $37 million ($22 million after-tax), which is included in discontinued operations in Dominion's Consolidated Statement of Income. Dominion used the market approach to estimate the fair value of Brayton Point's and Kincaid's long-lived assets. This was considered a Level 2 fair value measurement given it was based on the agreed-upon sales price. The carrying amounts of the major classes of assets and liabilities classified as held for sale in Dominion's Consolidated Balance Sheet are as follows:

At March 31,	2013
(millions)
Assets
Current assets	$	109
Property, plant and equipment, net	187
Other assets	17
Total assets	$	313
Liabilities
Current liabilities	$	28
Asset retirement obligations	19
Other liabilities	1
Total liabilities	$	48

The following table presents selected information regarding the results of operations of Brayton Point and Kincaid, which are reported as discontinued operations in Dominion's Consolidated Statements of Income:

	Three Months Ended March 31,
	2013		2012
(millions)
Operating revenue	$	154	$	65
Income (loss) before income taxes	1		(22		)

Dominion's 50% interest in Elwood is an equity method investment and therefore, in accordance with applicable accounting guidance, the carrying amount of this investment is not classified as held for sale nor are the equity earnings from this investment reported as discontinued operations.

Sale of Salem Harbor and State Line

In August 2012, Dominion completed the sale of Salem Harbor. During the second quarter of 2012, Dominion completed the sale of State Line, which ceased operations in March 2012.

The following table presents selected information regarding the results of operations of Salem Harbor and State Line, which are classified in discontinued operations in Dominion's Consolidated Statement of Income:

Accounting Policies [Abstract]

General

In Dominion’s and Virginia Power’s opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position as of March 31, 2013, and their results of operations and cash flows for the three months ended March 31, 2013 and 2012. Such adjustments are normal and recurring in nature unless otherwise noted.

The Companies make certain estimates and assumptions in preparing their Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods presented. Actual results may differ from those estimates.

Dominion’s and Virginia Power’s accompanying unaudited Consolidated Financial Statements include, after eliminating intercompany transactions and balances, their accounts and those of their respective majority-owned subsidiaries and those VIEs where Dominion has been determined to be the primary beneficiary.

The results of operations for interim periods are not necessarily indicative of the results expected for the full year. Information for quarterly periods is affected by seasonal variations in sales, rate changes, electric fuel and other energy-related purchases, purchased gas expenses and other factors.

Certain amounts in Dominion’s and Virginia Power’s 2012 Consolidated Financial Statements and Notes have been reclassified to conform to the 2013 presentation for comparative purposes. The reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows.

Amounts disclosed for Dominion are inclusive of Virginia Power, where applicable.

Variable Interest Entities [Abstract]

Variable Interest Entities

Variable Interest Entities

As discussed in Note 15 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012, certain variable pricing terms in some of the Companies’ long-term power and capacity contracts cause them to be considered variable interests in the counterparties.

Virginia Power has long-term power and capacity contracts with four non-utility generators with an aggregate summer generation capacity of approximately 870 MW. These contracts contain certain variable pricing mechanisms in the form of partial fuel reimbursement that Virginia Power considers to be variable interests. After an evaluation of the information provided by these entities, Virginia Power was unable to determine whether they were VIEs. However, the information they provided, as well as Virginia Power's knowledge of generation facilities in Virginia, enabled Virginia Power to conclude that, if they were VIEs, it would not be the primary beneficiary. This conclusion reflects Virginia Power's determination that its variable interests do not convey the power to direct the most significant activities that impact the economic performance of the entities during the remaining terms of Virginia Power's contracts and for the years the entities are expected to operate after its contractual relationships expire. The contracts expire at various dates ranging from 2015 to 2021. Virginia Power is not subject to any risk of loss from these potential VIEs other than its remaining purchase commitments which totaled $1.0 billion as of March 31, 2013. Virginia Power paid $55 million for electric capacity and $20 million and $19 million for electric energy to these entities in the three months ended March 31, 2013 and 2012, respectively.

Virginia Power purchased shared services from DRS, an affiliated VIE, of approximately $77 million and $96 million for the three months ended March 31, 2013 and 2012, respectively. Virginia Power determined that it is not the most closely associated entity with DRS and therefore not the primary beneficiary. DRS provides accounting, legal, finance and certain administrative and technical services to all Dominion subsidiaries, including Virginia Power. Virginia Power has no obligation to absorb more than its allocated share of DRS costs.

See Note 15 to the Consolidated Financial Statements in Dominion’s and Virginia Power’s Annual Report on Form 10-K for the year ended December 31, 2012 for additional information about consolidated VIEs.
