	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, 2013.
	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, 2014 and their results of operations and cash flows for the three months ended March 31, 2014 and 2013. 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 2013 Consolidated Financial Statements and Notes have been reclassified to conform to the 2014 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.

	Acquisitions and Dispositions
	Acquisition of Solar Development Projects
	In March 2014, Dominion completed the acquisition of 100% of the equity interests of six solar development projects in California from Recurrent Energy Development Holdings, LLC for approximately $50 million. The allocation of the purchase price to individual assets is under evaluation by management and has not been finalized.
	The projects are expected to cost approximately $450 million once constructed, including the initial acquisition cost. Upon completion, the facilities are expected to generate approximately 139 MW and will provide Dominion with a large utility-scale solar presence in the California market and significantly increase its solar generation portfolio.
	Long-term power purchase, interconnection, EPC and operation and maintenance agreements have been executed for each of the projects. Construction of the projects commenced in the first quarter of this year and all of the solar facilities are expected to enter commercial operations in late 2014 or early 2015. Dominion expects to claim federal investment tax credits on the projects.
	Sale of Electric Retail Energy Marketing Business
	In March 2014, Dominion completed the sale of its electric retail energy marketing business. The proceeds were approximately $187 million, net of transaction costs. The sale resulted in a gain, subject to post-closing adjustments, of approximately $100 million ($57 million after-tax) net of a $31 million write-off of goodwill, and is included in other operations and maintenance expense in Dominion's Consolidated Statement of Income. The sale of the electric retail energy marketing business did not qualify for discontinued operations classification.
	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 equity method investment in Elwood. In August 2013, Dominion completed the sale and received proceeds of approximately $465 million, net of transaction costs.
	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 impairment charges totaling $37 million ($22 million after-tax), which is included in discontinued operations in Dominion's Consolidated Statements 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 that it was based on the agreed-upon sales price.
	Dominion's 50% interest in Elwood was an equity method investment and therefore, in accordance with applicable accounting guidance, the carrying amount of this investment was not classified as held for sale nor were the equity earnings from this investment reported as discontinued operations.
	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:

	Assignment of Marcellus Acreage
	As discussed in Note 10 to Dominion’s Consolidated Financial Statements in its Annual Report on Form 10-K for the year ended December 31, 2013, DTI closed on agreements with two natural gas producers to convey approximately 100,000 acres of Marcellus Shale development rights underneath several of its natural gas storage fields.  In the first quarter of 2014, DTI received $12 million in additional cash proceeds resulting from post-closing adjustments. At March 31, 2014, deferred revenue totaled approximately $89 million, which will be recognized over the remaining terms of the agreements.

	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, 2013. 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, futures and options, 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 and futures 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. 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, risk-free rate of return, the option expiration dates, the option strike prices, the original sales prices, and volumes. For Level 3 fair value measurements, forward market prices and implied price volatilities 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 and Virginia Power'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.

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, which 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:
	31-Mar-14						31-Dec-13
	Carrying			Estimated Fair			Carrying			Estimated Fair
	Amount			Value(1)			Amount			Value(1)
(millions)

-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	Carrying amount includes amounts which represent the unamortized discount and premium. At March 31, 2014 and December 31, 2013, includes the valuation of certain fair value hedges associated with Dominion’s fixed rate debt of approximately $40 million and $55 million, respectively.
-3	Carrying amount includes amounts which represent the unamortized discount or premium.
-4	Carrying amount includes deferred issuance expenses of $2 million at December 31, 2013.

	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, 2013. 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 or similar arrangements and would reduce the net exposure.

Ineffectiveness and AOCI
For the three months ended March 31, 2014, 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, 2014:
	AOCI			Amounts Expected to be Reclassified to Earnings during the next 12 Months After-Tax			Maximum Term
	After-Tax
(millions)
Commodities:
Gas	$	(6	)	$	(6	)	25 months
Electricity	(135		)	(145		)	33 months
Other	—			—			26 months
Interest rate	(137		)	(7		)	366 months
Total	$	(278	)	$	(158	)
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.

	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. Any estimated range is based on currently available information, involves elements of judgment and significant uncertainties and 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. 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. Virginia Power purchases and, under its FERC market-based rate authority, sells electricity in the wholesale market. 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 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. 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. 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.
	In March 2014, FERC issued an order excluding from Virginia Power’s transmission rates for wholesale transmission customers located outside Virginia the incremental costs of undergrounding certain transmission line projects.  FERC found it is not just and reasonable for non-Virginia wholesale transmission customers to be allocated the incremental costs of undergrounding the facilities because the projects are a direct result of Virginia legislation and Virginia Commission pilot programs intended to benefit the citizens of Virginia. The order is retroactively effective as of March 2010 and will cause the reallocation of the costs charged to wholesale transmission customers outside Virginia to wholesale transmission customers in Virginia.  FERC determined that there was not sufficient evidence on the record to determine the magnitude of the underground increment and ordered a hearing to determine the appropriate amount of undergrounding cost to be allocated to each wholesale transmission customer in Virginia. The hearing is held in abeyance pending settlement proceedings ordered by FERC.  While Virginia Power cannot predict the outcome of the hearing and settlement proceedings, 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, 2013.
	Virginia Regulation
	Rate Adjustment Clauses
	Below are developments to significant riders associated with various Virginia Power projects:
	•	The Virginia Commission previously approved Rider B in conjunction with the conversion of three power stations to biomass. In February 2014, the Virginia Commission approved an approximately $15 million revenue requirement for the rate year beginning April 1, 2014, which represents a $3 million increase to the revenue requirement over the previous year.
	•	The Virginia Commission previously approved Rider S in conjunction with the Virginia City Hybrid Energy Center. In March 2014, the Virginia Commission approved an approximately $239 million revenue requirement for the rate year beginning April 1, 2014, which represents a $9 million decrease to the revenue requirement versus the previous year.
	•	The Virginia Commission previously approved Rider W in conjunction with Warren County. In February 2014, the Virginia Commission approved an approximately $98 million revenue requirement for the rate year beginning April 1, 2014, which represents a $15 million increase to the revenue requirement over the previous year.
	North Anna COL
	Virginia Power is considering the construction of a third nuclear unit at a site located at North Anna. If Virginia Power decides to build a new unit, it must first receive a COL from the NRC, approval of the Virginia Commission and certain environmental permits and other approvals. In April 2013, Virginia Power decided to replace the reactor design previously selected for a potential unit with ESBWR technology. Virginia Power filed the first of its two-part amendment to the COL application with the NRC in July 2013 to reflect the ESBWR technology and filed the second part of the amendment in December 2013. The COL is expected in 2016. Virginia Power has not yet committed to building a new nuclear unit at North Anna.
	In February 2014, BREDL filed a petition with NRC seeking to stay final decision making in the COL proceeding until a rulemaking petition filed by a number of environmental groups several weeks earlier is resolved. The suspension request and underlying petition for rulemaking are based on analyses of the consequences of a spent fuel pool fire, but none of the analyses relates specifically to the ESBWR design. Substantially identical suspension petitions and contentions were filed by various intervenor groups in other licensing proceedings pending before the NRC. In March 2014, BREDL filed a motion to reopen the COL proceeding on seismic issues under a previous ruling of the ASLB. No other issues were raised by BREDL in its filing. Virginia Power and the NRC Staff have filed answers opposing both the motion and petition.
	North Anna and Offshore Wind Legislation
	In April 2014, the Virginia Governor signed legislation into law that permits Virginia Power to recover 70% of the costs previously deferred or capitalized related to the development of a third nuclear unit located at North Anna and the development of offshore wind facilities through December 31, 2013 as part of the 2013 and 2014 base rates. Virginia Power has deferred or capitalized costs totaling $577 million for these projects as of December 31, 2013, substantially all of which relate to North Anna. For the portion of these previously deferred or capitalized costs allocable to customers in Virginia, Virginia Power will recognize 70% as a charge against net income in 2014. The remaining deferred or capitalized costs, as well as costs incurred after December 31, 2013, continue to be eligible for inclusion in a future rate adjustment clause. The legislation goes into effect July 1, 2014.
	Ohio Regulation
	PIR Program
	In 2008, East Ohio began PIR, aimed at replacing approximately 20% of its pipeline. In February 2014, East Ohio filed an application with the Ohio Commission requesting approval to adjust the PIR cost recovery rates for 2013 costs. The application includes a gross plant investment for 2013 of $164 million, a cumulative gross plant investment of $674 million and an estimated revenue requirement of $89 million. This application was approved by the Ohio Commission in April 2014.
	FERC Regulation
	DTI Settlement
	In mid-2013, DTI received concerns about its fuel retainage percentages and apparent over-recovery of fuel costs during certain time periods reflected in its annual fuel reports. In December 2013, DTI submitted for FERC approval of a stipulation and agreement addressing, among other things, reductions in its fuel retainage percentages and a rate moratorium through 2016. In February 2014, FERC approved the stipulation and agreement.
	The revised fuel retainage percentages became effective January 1, 2014. DTI began assessing the reduced fuel retainage percentages on March 1, 2014, and as a result provided refunds totaling nearly $10 million. The refunds reflect, with interest, the value of the difference between the actual quantities of fuel retained for the months of January and February and the quantities that would have been retained using the reduced percentages. The reduction in fuel retention is expected to reduce DTI’s revenues by approximately $35 million in 2014.

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, 2013, 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 $807 million as of March 31, 2014. Virginia Power paid $56 million and $55 million for electric capacity and $54 million and $20 million for electric energy to these entities in the three months ended March 31, 2014 and 2013, respectively.
	Virginia Power purchased shared services from DRS, an affiliated VIE, of approximately $108 million and $77 million for the three months ended March 31, 2014 and 2013, 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.

	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, 2014, Dominion’s commercial paper and letters of credit outstanding, as well as its capacity available under credit facilities, were as follows:
		Facility		Outstanding		Outstanding		Facility
		Limit		Commercial		Letters of		Capacity
				Paper		Credit		Available
	(millions)
	Joint revolving credit facility(1)	$	3,000	$	1,972	$	—	$	1,028
	Joint revolving credit facility(2)	500		—		237		263
	Total	$	3,500	$	1,972	$	237	$	1,291
	-1	This credit facility has a maturity date of September 2018, 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	This credit facility has a maturity date of September 2018, and 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, 2014, 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		Outstanding		Outstanding		Facility
		Sub-limit		Commercial		Letters of		Sub-limit Capacity
				Paper		Credit		Available
	(millions)
	Joint revolving credit facility(1)	$	1,000	$	503	$	—	$	497
	Joint revolving credit facility(2)	250		—		53		197
	Total	$	1,250	$	503	$	53	$	694
	-1	This credit facility has a maturity date of September 2018, 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	This credit facility has a maturity date of September 2018, and 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 2018. As of March 31, 2014, this facility supports approximately $119 million of certain variable rate tax-exempt financings of Virginia Power.
	Long-term Debt
	In February 2014, Virginia Power issued $350 million of 3.45% senior notes, and $400 million of 4.45% senior notes, that mature in 2024, and 2044, respectively.
	In March 2014, Dominion issued $400 million of 1.25% senior notes that mature in 2017.
	In February 2014, Virginia Power provided notice to redeem the $10 million 2.5% and the $30 million 2.5% Industrial Development Authority of the Town of Louisa, Virginia Solid Waste and Sewage Disposal Revenue Bonds, Series 1997A and 2000A, that would otherwise mature in April 2022 and September 2030, respectively. At March 31, 2014, the bonds were included in securities due within one year in Virginia Power’s Consolidated Balance Sheets. In April 2014, Virginia Power redeemed the bonds for $40 million, the amount of principal then outstanding plus accrued interest.
	Convertible Securities
	At March 31, 2014, Dominion had $40 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, 2014, the conversion rate had been adjusted, primarily due to individual dividend payments above the level paid at issuance, to 29.9961 shares of common stock per $1,000 principal amount of senior notes, which represents a conversion price of $33.34. If the outstanding notes as of March 31, 2014 were all converted, it would result in the issuance of approximately 600,000 additional shares of common stock.
	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, the notes are called for redemption by Dominion and upon the occurrence of certain other conditions. During the first quarter of 2014, the senior notes were eligible for conversion and approximately $3 million of the notes were converted by holders into $3 million of common stock. The senior notes are eligible for conversion during the second quarter of 2014.
	Preferred Stock
	In February 2014, Virginia Power provided irrevocable notice to redeem all 1,250,000 outstanding shares of its Flex MMP Stock. In March 2014, Virginia Power redeemed the stock at a price of $100 per share plus accumulated and unpaid dividends at a rate reset in March 2011 of 6.12%. Dividends ceased accumulating on the stock upon payment of the redemption price, thus the rate was not reset in March 2014.
	Issuance of Common Stock
	Dominion maintains Dominion Direct® and a number of employee savings plans through which contributions may be invested in Dominion’s common stock. These shares may either be newly issued or purchased on the open market with proceeds contributed to these plans. In January 2014, Dominion began purchasing its common stock on the open market for these plans. In April 2014, Dominion began issuing new common shares for these direct stock purchase plans.

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, and/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. Any accrued liability is recorded on a gross basis with a receivable also recorded for any probable insurance recoveries. Estimated ranges of loss are inclusive of legal fees and net of any anticipated insurance recoveries. Any estimated range is based on currently available information, involves elements of judgment and significant uncertainties and 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 NOX 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 NOx emissions cap and trade programs that were completely independent of the current ARP. Specifically, CSAPR required reductions in SO2 and NOx emissions from fossil fuel-fired electric generating units of 25 MW or more through annual NOx emissions caps, NOx 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 were 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. In June 2013, the U.S. Supreme Court granted the EPA's petition seeking review of the D.C. Circuit's decision that vacated and remanded 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.
	Water
	The CWA, as amended, is a comprehensive program utilizing 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 applicable aspects of the CWA program 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. Preliminary costs for options under evaluation for the site range from $1 million to $22 million. A remedy has not been selected. Due to the uncertainty surrounding the other sites, Dominion is unable to make an estimate of the potential financial statement impacts.
	Climate Change Legislation and Regulation
	In April 2012, the EPA published proposed NSPS for GHG emissions for new electric generating units. This proposed rule set national emission standards for new coal, oil, integrated gasification, and combined cycle units larger than 25MW. The
	proposed rule covered CO2 only and does not apply to existing sources. The proposed rule also does not apply to any new or
	existing biomass units. In June 2013, the President of the U.S. released a Climate Action Plan focusing on ways to meet the national GHG reduction goal of 17% from 2005 levels by 2020. Pursuant to the Presidential Memorandum issued in conjunction with the Climate Action Plan, the EPA withdrew the April 2012 proposal and re-proposed the NSPS standards for new sources on January 8, 2014 and is expected to finalize the rule in 2014 or early 2015. The Presidential Memorandum also directed the EPA to propose a rule for reconstructed, modified and existing sources of GHG emissions no later than June 2014, and issue a final rule no later than June 2015, to provide guidelines to the states to achieve the required GHG reductions. In March 2014, a national Strategy to Reduce Methane Emissions was published as part of the Climate Action Plan. The plan outlines a strategy to further reduce both domestic and international methane emissions from a number of key sources, including the oil and natural gas industry, and outlines the Administration’s efforts to improve measurement of these emissions. In April 2014, the EPA published five white papers on methane emissions and potential mitigation options related to the oil and gas industry. Dominion currently cannot predict the direct or indirect financial impact on operations from these GHG initiatives, but believes the expenditures to comply with any new requirements could be material.
	In October 2013, the U.S. Supreme Court granted petitions filed by several industry groups, states, and the U.S. Chamber of Commerce seeking review of the D.C. Circuit Court's June 2012 decision upholding the EPA’s regulation of GHG under the CAA. The court’s decision could potentially impact EPA's continued implementation of current Prevention of Significant Deterioration regulations applicable to stationary sources in relation to GHG. It is not anticipated, however, that the court's decision would affect the EPA’s development of the GHG NSPS rules for new or existing sources, as the authority for those rules comes from a different section of the CAA than what is at issue in the Supreme Court case. It is uncertain at this time whether the court’s decision will have any material impact on Dominion's operations.
	In July 2011, the EPA signed a final rule deferring the need for Prevention of Significant Deterioration and Title V permitting for CO2 emissions for biomass projects. This rule temporarily deferred for a period of up to 3 years the consideration of CO2 emissions from biomass projects when determining whether a stationary source meets the Prevention of Significant Deterioration and Title V applicability thresholds, including those for the application of best available control technology.  In July 2013, the U.S. Court of Appeals for the D.C. Circuit vacated this rule; however a mandate making this decision effective has not been issued.  Virginia Power converted three coal-fired generating stations, Altavista, Hopewell and Southampton, to biomass during the CO2 deferral period.  It is unclear how the court's decision will affect biomass sources that were permitted during the deferral period, however the expenditures to comply with any new requirements could be material.
	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. Implementation of these enhancements is currently in progress. 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. The updated seismic analyses are complete, and only North Anna requires further evaluation in accordance with the NRC's approved guidance. 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.

	At March 31, 2014, Dominion had issued $69 million of guarantees, primarily to support equity method investees. No significant amounts related to these guarantees have been recorded. As of March 31, 2014, Dominion’s exposure under these guarantees was $54 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, 2014, Dominion's maximum remaining cumulative exposure under these equity funding agreements was $80 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, 2014, Dominion had issued the following subsidiary guarantees:
		Stated Limit		Value(1)
	(millions)
	Subsidiary debt(2)	$	27	$	27
	Commodity transactions(3)	3,056		470
	Nuclear obligations(4)	265		96

	Other(7)	582		85
	Total	$	4,358	$	995
	-1	Represents the estimated portion of the guarantee's stated limit that is utilized as of March 31, 2014 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	Guarantee of debt of a DEI subsidiary. In the event of default by the subsidiary, 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 certain 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 Cove Point, including agreements to support terminal service and transportation agreements as well as an engineering, procurement and construction contract for new liquefaction facilities. Includes certain guarantees that do not have stated limits.
	-6	Includes guarantees to facilitate the development of solar projects including guarantees to support the issuance of limited notice to proceed and full notice to proceed under EPC agreements as well as to support payment obligations under module supply agreements. Includes certain guarantees that do not have stated limits.
	-7	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.
	Surety Bonds and Letters of Credit
	As of March 31, 2014, Dominion had purchased $148 million of surety bonds, including $60 million at Virginia Power, and authorized the issuance of letters of credit by financial institutions of $237 million, including $53 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.

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, 2013.
	At March 31, 2014, Dominion's credit exposure totaled $242 million. Of this amount, investment grade counterparties, including those internally rated, represented 61%. No counterparty exposure exceeded 10% of Dominion's total exposure.
	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, 2014 and December 31, 2013, Dominion would have been required to post an additional $38 million and $146 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 approximately $46 million and $76 million in collateral at March 31, 2014 and December 31, 2013, respectively, 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, 2014 and December 31, 2013 was $122 million and $169 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, 2014 and December 31, 2013. See Note 9 for further information about derivative instruments.

	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. In Virginia Power's Consolidated Balance Sheets at March 31, 2014 and December 31, 2013, amounts due to Dominion associated with these benefit plans included in other deferred credits and other liabilities were $163 million and $147 million, respectively, and amounts due from Dominion at March 31, 2014 included in other deferred charges and other assets were $8 million. 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, 2014 and December 31, 2013, Virginia Power's derivative assets and liabilities with affiliates were not material.
	DRS and other affiliates provide accounting, legal, finance and certain administrative and technical services to Virginia Power. In addition, Virginia Power provides certain services to affiliates, including charges for facilities and equipment usage.
	Presented below are significant transactions with DRS and other affiliates:
		Three Months Ended March 31,

	Virginia Power has borrowed funds from Dominion under short-term borrowing arrangements. There were $159 million and $97 million in short-term demand note borrowings from Dominion as of March 31, 2014 and December 31, 2013, respectively. Virginia Power had no outstanding borrowings, net of repayments under the Dominion money pool for its nonregulated subsidiaries as of March 31, 2014 and December 31, 2013. Interest charges related to Virginia Power's borrowings from Dominion were not material for the three months ended March 31, 2014 and 2013.

		Nonregulated retail energy marketing	X
	Dominion Energy	Gas transmission and storage(1)	X
		Gas distribution and storage	X
		LNG import and storage	X
	-1	Includes remaining producer services activities.
	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 discontinued or sold. 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 January of 2014, Dominion announced it would exit the electric retail energy marketing business. Dominion completed the sale in March 2014. As a result, the earnings impact from electric retail energy marketing business has been included in the Corporate and Other Segment of Dominion for 2014.
	In the second quarter of 2013, Dominion commenced a repositioning of its producer services business, which aggregates natural gas supply, engages in natural gas trading and marketing activities and natural gas supply management and provides price risk management services to Dominion affiliates. The repositioning was completed in the first quarter of 2014 and resulted in the termination of natural gas trading and certain energy marketing activities. As a result, the earnings impact from natural gas trading and certain energy marketing activities has been included in the Corporate and Other Segment of Dominion for 2014.
	In the three months ended March 31, 2014, Dominion reported an after-tax net expense of $228 million for specific items in the Corporate and Other segment, with $217 million of these net expenses attributable to its operating 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.
	The net expense for specific items in 2014 primarily related to the impact of the following items:
	•	A $319 million ($193 million after-tax) net loss related to the producer services business discussed above, attributable to Dominion Energy; and
	•	A $47 million ($33 million after-tax) net loss related to the electric retail energy marketing business discussed above, including a $147 million ($90 million after-tax) loss from normal operations, partially offset by a $100 million ($57 million after-tax) gain on sale net of a $31 million write-off of goodwill, attributable to Dominion Generation.
	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 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, 2014 or 2013.

	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, 2014 and their results of operations and cash flows for the three months ended March 31, 2014 and 2013. 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 2013 Consolidated Financial Statements and Notes have been reclassified to conform to the 2014 presentation for comparative purposes. The reclassifications did not affect the Companies’ net income, total assets, liabilities, equity or cash flows.

[2]	Carrying amount includes amounts which represent the unamortized discount and premium. At March 31, 2014 and December 31, 2013, includes the valuation of certain fair value hedges associated with Dominion’s fixed rate debt of approximately $40 million and $55 million, respectively.
[3]	Carrying amount includes amounts which represent the unamortized discount or premium.
[4]	Carrying amount includes deferred issuance expenses of $2 million at December 31, 2013.
