	As permitted by the rules and regulations of the SEC, the Companies' 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, Dominion’s and Virginia Power’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2014 and Exhibits 99.11(b) and 99.11(c) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014.
	In the Companies' opinion, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly their financial position as of June 30, 2014, their results of operations for the three and six months ended June 30, 2014 and 2013, and their cash flows for the six months ended June 30, 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.
	The Companies' 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 the Companies' 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 and/or Dominion Gas, where applicable.

	Acquisitions and Dispositions
	Dominion
	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 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.
	In May 2014, Dominion completed the acquisition of 100% of the equity interests of two solar development projects in Tennessee from Strata Solar Development, LLC for $2 million. The projects are expected to cost approximately $70 million once constructed, including the initial acquisition cost. Upon completion, the facilities are expected to generate approximately 32 MW.
	The purchase price for each of these acquisitions was allocated to Property, Plant and Equipment.
	In May 2014, Dominion entered into an agreement to acquire 100% of the equity interests of a solar project in California from EDF Renewable Development, Inc. for approximately $70 million.  The acquisition is expected to close later this year prior to the project commencing operations.  The project is expected to cost approximately $75 million once constructed, including the initial acquisition cost. Upon completion, the facilities are expected to generate approximately 20 MW.
	Long-term power purchase, interconnection, EPC and operation and maintenance agreements have been executed for each of the acquired projects. Construction of the projects has commenced and all of the solar facilities are expected to enter commercial operations in late 2014. 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 Statements of Income. The sale of the electric retail energy marketing business did not qualify for discontinued operations classification.
	Sale of Illinois Gas Contracts
	In June 2013, Dominion completed the sale of Illinois Gas Contracts. The sales price was approximately $32 million, subject to post-closing adjustments. The sale resulted in a gain of approximately $29 million ($18 million after-tax) net of a $3 million write-off of goodwill, and is included in other operations and maintenance expense in Dominion’s Consolidated Statements of Income. The sale of Illinois Gas Contracts 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 and second quarters 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 $48 million ($28 million after-tax) for the six month period ended June 30, 2013, including $11 million ($6 million after-tax) for the three month period ended June 30, 2013, which are 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. These were considered Level 2 fair value measurements given that they were 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:
		Three Months Ended June 30,			Six Months Ended June 30,
		2013			2013
	(millions)
	Operating revenue	$	63		$	217

	Dominion Gas
	Assignment of Marcellus Acreage
	In December 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.  The agreements provide for payments to DTI, subject to customary adjustments, of approximately $200 million over a period of nine years, and an overriding royalty interest in gas produced from the acreage. During the six months ended June 30, 2014, DTI received $16 million in additional cash proceeds resulting from post-closing adjustments. At June 30, 2014, deferred revenue totaled approximately $91 million, which is expected to be recognized over a period of approximately nine years.

	Fair Value Measurements
	The Companies' fair value measurements are made in accordance with the policies discussed in Note 6 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 and Note 6 in Exhibit 99.11(b) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014. See Note 9 in this report for further information about their derivatives and hedge accounting activities.
	The Companies enter into certain physical and financial forwards, futures, options and swaps, 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 the Companies' quantitative information about Level 3 fair value measurements at June 30, 2014. The range and weighted average are presented in dollars for market price inputs and percentages for price volatility.

	See Note 3 for non-recurring fair value measurements related to Brayton Point and Kincaid.
	Dominion Gas
	In June 2013, Dominion Gas purchased certain natural gas infrastructure facilities that were previously leased from third parties. The purchase price was based on terms in the lease, which exceeded current market pricing. As a result of the purchase price and expected losses, Dominion Gas recorded an impairment charge of $49 million ($29 million after-tax) in other operations and maintenance expense in its Consolidated Statements of Income, to write down the long-lived assets to their estimated fair values of less than $1 million. As management was not aware of any recent market transactions for comparable assets with sufficient transparency to develop a market approach to fair value, Dominion Gas used the income approach (discounted cash flows) to estimate the fair value of the assets in this impairment test. This was considered a Level 3 fair value measurement due to the use of significant unobservable inputs, including estimates of future production and other commodity prices.
	Also in June 2013, Dominion Gas recorded an impairment charge of $6 million ($4 million after-tax) in other operations and
	maintenance expense in its Consolidated Statements of Income, to write off previously capitalized costs following the cancellation of two development projects.

Fair Value of Financial Instruments
Substantially all of the Companies' 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, affiliated current borrowings, payables to affiliates and accounts payable are representative of fair value because of the short-term nature of these instruments. For the Companies' financial instruments that are not recorded at fair value, the carrying amounts and estimated fair values are as follows:
	30-Jun-14						31-Dec-13
	Carrying			Estimated Fair			Carrying			Estimated Fair

-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/or premium. At June 30, 2014 and December 31, 2013, includes the valuation of certain fair value hedges associated with fixed rate debt of approximately $54 million and $55 million, respectively.
-3	Carrying amount includes amounts which represent the unamortized discount and/or premium.
-4	Carrying amount includes deferred issuance expenses of $2 million at December 31, 2013.

	Derivatives and Hedge Accounting Activities
	The Companies' accounting policies and objectives and strategies for using derivative instruments are discussed in Note 2 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 and Note 2 in Exhibit 99.11(b) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014. 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 the Companies' 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. Dominion Gas' derivative contracts consist of over-the-counter transactions. 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 the Companies' 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 and six months ended June 30, 2014 and 2013, 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 June 30, 2014:
	AOCI			Amounts Expected to be Reclassified to Earnings during the next 12 Months After-Tax			Maximum Term

Other	(1		)	(1		)	23 months
Interest rate	(179		)	(7		)	363 months
Total	$	(353	)	$	(154	)
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.

Dominion Gas
Equity Method Investment
Dominion Gas accounts for the following investment under the equity method of accounting:
Company	Ownership%		Investment Balance						Description
			30-Jun-14			31-Dec-13
(millions)
Iroquois	24.72	%	$	113		$	105		Gas transmission system
Total			$	113		$	105
Dominion Gas' equity earnings on this investment totaled $13 million for both the six months ended June 30, 2014 and 2013. Dominion Gas received distributions from this investment of $5 million for both the six months ended June 30, 2014 and 2013. As of June 30, 2014 and December 31, 2013, the carrying amount of Dominion Gas' investment exceeded its share of underlying equity in net assets by approximately $9 million and $8 million, respectively. The differences reflect equity method goodwill and are not being amortized.
Dominion and Dominion Gas
Blue Racer
In December 2012, Dominion formed Blue Racer with Caiman to provide midstream services to natural gas producers operating in the Utica Shale region in Ohio and portions of Pennsylvania. Blue Racer is an equal partnership between Dominion and Caiman, with Dominion contributing midstream assets and Caiman contributing private equity capital. In June 2014, Blue Racer achieved equalization.
In March 2013, Dominion Gas sold Line TL-404 to an affiliate, that subsequently sold Line TL-404 to Blue Racer for cash proceeds of approximately $47 million. The sale resulted in a gain of approximately $25 million ($14 million after-tax) net of a $2 million write-off of goodwill, and is included in other operations and maintenance expense in both Dominion Gas' and Dominion's Consolidated Statement of Income.
Dominion NGL Pipelines, LLC was contributed in January 2014 by Dominion to Blue Racer, prior to commencement of service, resulting in an increased equity method investment of $155 million, including $6 million of goodwill allocated from Dominion's goodwill balance to its equity method investment in Blue Racer.
In March 2014, Dominion Gas sold the Northern System to an affiliate, that subsequently sold the Northern System to Blue Racer for consideration of approximately $84 million. Dominion' Gas' consideration consisted of $17 million in cash proceeds and the extinguishment of affiliated current borrowings of $67 million and Dominion's consideration consisted of cash proceeds of approximately $84 million. The sale resulted in a gain of approximately $59 million ($35 million after-tax for Dominion Gas and $34 million after-tax for Dominion) net of a $3 million write-off of goodwill, and is included in other operations and maintenance expense in both Dominion Gas' and Dominion's Consolidated Statement of Income.

	Regulatory Matters
	Regulatory Matters Involving Potential Loss Contingencies
	As a result of issues generated in the ordinary course of business, the Companies 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 the Companies' 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 state of Georgia and in the PJM, MISO and ISO-NE regions 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 with loads outside Virginia to wholesale transmission customers with loads 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 has been held in abeyance pending the outcome of an ongoing settlement proceeding, as 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, Note 12 to the Consolidated Financial Statements in Dominion's and Virginia Power's Quarterly Report on Form 10-Q for the quarter ended March 31, 2014, Note 12 in Exhibit 99.11(b) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014 and Note 11 in Exhibit 99.11(c) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014.
	Virginia Regulation
	Virginia Fuel Expenses
	In May 2014, Virginia Power submitted its annual fuel factor filing to the Virginia Commission to recover an estimated $1.9 billion in Virginia jurisdictional projected fuel expense for the rate year beginning July 1, 2014. Virginia Power also offered to defer recovery of 50% of its total estimated $268 million jurisdictional deferred fuel balance to the 2015-2016 fuel year, thereby recovering $134 million of its jurisdictional deferred fuel balance for the rate year beginning July 1, 2014. In May 2014, the Virginia Commission issued an order approving the increased fuel rate on an interim basis effective July 1, 2014. This case is pending.
	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 June 2014,Virginia Power proposed an approximately $13 million revenue requirement for the rate year beginning April 1, 2015. This case is pending.
	•	The Virginia Commission previously approved Rider S in conjunction with the Virginia City Hybrid Energy Center. In June 2014, Virginia Power proposed an approximately $244 million revenue requirement for the rate year beginning April 1, 2015. This case is pending.
	•	The Virginia Commission previously approved Rider W in conjunction with Warren County. In May 2014, Virginia Power proposed an approximately $135 million revenue requirement for the rate year beginning April 1, 2015. This case is pending.
	•	The Virginia Commission previously approved Rider R in conjunction with Bear Garden. In June 2014, Virginia Power proposed an approximately $84 million revenue requirement for the rate year beginning April 1, 2015. This case is pending.
	•	The Virginia Commission previously approved Rider BW in connection with Brunswick County. In July 2014, the Virginia Commission approved an approximately $85 million revenue requirement for the rate year beginning September 1, 2014, which represents an approximately $41 million increase over the previous year.
	•	The Virginia Commission previously approved Riders C1A and C2A in connection with various DSM programs. In April 2014, the Virginia Commission approved an approximately $1 million revenue requirement for Rider C1A, and an approximately $30 million revenue requirement for Rider C2A, for the rate year beginning May 1, 2014, which represents an approximately $4 million increase to the total revenue requirement for both Riders over the previous year. The Virginia Commission also approved a combined spending cap of approximately $72 million, inclusive of lost revenues, for three new DSM programs.
	•	The Virginia Commission previously approved Rider T1. In July 2014, the Virginia Commission approved an approximately $538 million revenue requirement for the rate year beginning September 1, 2014, which represents an approximately $134 million increase over the previous year.
	Electric Transmission Projects
	In April 2014, the Virginia Commission issued an order granting Virginia Power a CPCN to rebuild within existing rights-of-way its 500-kV Loudoun-Pleasant View transmission line in Loudoun County at an estimated cost of approximately $31 million.
	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 the 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. The NRC denied the petition in July 2014. 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. In June 2014, the ASLB denied BREDL’s motion to reopen the COL proceeding. BREDL did not appeal the ASLB’s decision, and under a previous ruling of the NRC, the contested portion of the COL proceeding remains terminated.
	North Anna and Offshore Wind Legislation
	In April 2014 legislation was enacted in Virginia 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 offshore wind facilities through December 31, 2013 as part of the 2013 and 2014 base rates. Virginia Power has deferred or capitalized costs totaling approximately $577 million for these projects as of December 31, 2013, substantially all of which relate to North Anna. For the 70% portion of these previously deferred or capitalized costs allocable to customers in Virginia, Virginia Power will recognize such amounts that are now recoverable in 2013 and 2014 base rates as charges against net income beginning in the second quarter of 2014 and for the remainder of the year. In the second quarter of 2014, Virginia Power recognized a $287 million ($191 million after-tax) charge against income representing the cumulative recovery of costs from January 2013 through June 2014 and will recognize additional charges of approximately $87 million ($57 million after-tax) ratably during the remainder of 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.
	North Carolina Regulation
	In December 2012, the North Carolina Commission approved a $36 million increase in Virginia Power’s annual non-fuel base revenues based on an authorized ROE of 10.2%, and a $14 million decrease in annual base fuel revenues for a combined total base revenue increase of $22 million. These rate changes became effective on January 1, 2013 and were appealed to the North Carolina Supreme Court by multiple parties. In June 2014, the Supreme Court of North Carolina issued an opinion reversing the portion of the North Carolina Commission’s December 2012 order from Virginia Power’s 2012 base rate case approving a 10.2% ROE for Virginia Power, and remanding the case to the North Carolina Commission for additional findings of fact in light of a 2013 opinion issued after the North Carolina Commission’s order. This case is pending.
	Ohio Regulation
	PIR Program
	In 2008, East Ohio began PIR, aimed at replacing more than 20% of its pipeline. In May 2014, PIR cost recovery rates became effective as approved by the Ohio Commission in April 2014. The approval includes a revenue requirement of $89 million, which represents an approximately $22 million increase over the previous year.
	AMR Program
	In 2007, East Ohio began installing automated meter reading technology for its 1.2 million customers in Ohio. In May 2014, AMR cost recovery rates became effective as approved by the Ohio Commission in April 2014. The approval includes a revenue requirement of $8 million, which represents an approximately $3 million increase over the previous year.
	House Bill 95
	Ohio enacted utility reform legislation under House Bill 95, which became effective in September 2011. This law updates natural gas legislation by enabling gas companies to include more up-to-date cost levels when filing rate cases. It also allows gas companies to seek approval of capital expenditure plans under which gas companies can recognize carrying costs on associated capital investments placed in service and can defer the carrying costs plus depreciation and property tax expenses for recovery from ratepayers in the future.
	In July 2014, the Ohio Commission approved East Ohio’s application requesting authority to implement a capital expenditure program for 2014 capital expenditures totaling $110 million.
	PIPP Plus Program
	Under the Ohio PIPP Plus Program, eligible customers can make reduced payments based on their ability to pay their bill. The difference between the customer’s total bill and the PIPP payment plan amount is deferred and collected under the PIPP Rider in accordance with the rules of the Ohio Commission. In July 2014, East Ohio’s annual update of the PIPP Rider was automatically approved by the Ohio Commission after a 45-day waiting period from the date of the filing.  The increased rider rate reflects the refund over the next year of an over-recovery of accumulated arrearages of approximately $82 million as of March 31, 2014, net of projected deferred program costs of approximately $96 million for the period from April 2014 through June 2015.
	UEX Rider
	East Ohio has approval for a UEX Rider through which it recovers the bad debt expense of most customers not participating in the PIPP Plus Program. The UEX Rider is adjusted annually to achieve dollar for dollar recovery of East Ohio’s actual write-offs of uncollectible amounts. In July 2014, the Ohio Commission approved a decrease to East Ohio’s UEX Rider, which reflects the elimination of the over-recovered balance of accumulated bad debt expense of approximately $8 million as of March 31, 2014, and recovery of prospective bad debt expense projected to total approximately $25 million for the twelve-month period from April 2014 to March 2015.

	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 and Note 14 in Exhibit 99.11(b) to Dominion Gas' Current Report on Form 8-K dated June 26, 2014, certain variable pricing terms in some of the Companies’ 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 June 30, 2014. Virginia Power paid $55 million and $53 million for electric capacity and $33 million and $26 million for electric energy to these entities in the three months ended June 30, 2014 and 2013, respectively. Virginia Power paid $111 million and $108 million for electric capacity and $87 million and $46 million for electric energy to these entities in the six months ended June 30, 2014 and 2013, respectively.
	Virginia Power and Dominion Gas purchased shared services from DRS, an affiliated VIE, of approximately $106 million and and $26 million for the three months ended June 30, 2014, $83 million and $25 million for the three months ended June 30, 2013, $214 million and $52 million for the six months ended June 30, 2014, and $160 million and $51 million for the six months ended June 30, 2013, respectively. Virginia Power and Dominion Gas determined that each is not the most closely associated entity with DRS and therefore neither is the primary beneficiary. DRS provides accounting, legal, finance and certain administrative and technical services to all Dominion subsidiaries, including Virginia Power and Dominion Gas. Virginia Power and Dominion Gas have no obligation to absorb more than their allocated shares of DRS costs.

	Significant Financing Transactions
	Credit Facilities and Short-term Debt
	The Companies 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.
	Dominion
	At June 30, 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)	$	4,000		$	2,848		$	—		$	1,152
	Joint revolving credit facility(2)	500			232			115			153
	Total	$	4,500		$	3,080		$	115		$	1,305
	-1	In May 2014, this credit facility was amended and restated. The facility limit was increased from $3 billion to $4 billion and the maturity date was extended from September 2018 to April 2019. This credit facility 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	In May 2014, this credit facility was amended and restated and the maturity date was extended from September 2018 to April 2019. This credit facility can be used to support bank borrowings, commercial paper and letter of credit issuances.
	Virginia Power
	Virginia Power’s short-term financing is supported by two joint revolving credit facilities with Dominion and Dominion Gas. 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 June 30, 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 and Dominion Gas were as follows:
		Facility			Outstanding			Outstanding			Facility
		Sub-limit(3)			Commercial			Letters of			Sub-limit Capacity
					Paper			Credit			Available(3)
	(millions)
	Joint revolving credit facility(1)	$	1,000		$	1,091		$	—		$	(91	)
	Joint revolving credit facility(2)	250			232			18			—
	Total	$	1,250		$	1,323		$	18		$	(91	)
	-1	In May 2014, this credit facility was amended and restated and the maturity date was extended from September 2018 to April 2019. This credit facility 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	In May 2014, this credit facility was amended and restated and the maturity date was extended from September 2018 to April 2019. 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.
	-3	On June 30, 2014, Virginia Power's facility sub-limit was exceeded; however, Virginia Power retained ongoing access to its short-term demand note with Dominion as discussed in Note 17 and remained in compliance with its debt covenants. Effective July 10, 2014, Virginia Power increased its sub-limit under the $4 billion credit facility from $1.0 billion to $1.25 billion bringing its total sub-limit to $1.5 billion.
	In addition to the credit facility commitments mentioned above, Virginia Power also has a $120 million credit facility. In May 2014, this credit facility was amended and restated and the maturity date was extended from September 2018 to April 2019. As of June 30, 2014, this facility supports approximately $119 million of certain variable rate tax-exempt financings of Virginia Power.
	Dominion Gas
	Dominion Gas’ short-term financing is supported by the two joint revolving credit facilities discussed above with Dominion and Virginia Power, to which Dominion Gas was added as a borrower in May 2014.
	Dominion Gas’ current sub-limit under the $4 billion credit facility is $500 million, all of which is currently available, and can be increased or decreased multiple times per year, up to a maximum of $1 billion. Dominion Gas’ current sub-limit under the $500 million credit facility is $0 and can also be increased or decreased multiple times per year. The maturity date for both facilities is April 2019.
	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 April 2014, Virginia Power redeemed 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 have matured in April 2022 and September 2030, respectively.
	In June 2014, Dominion Gas commenced an offer to exchange $1.2 billion principal amount of unsecured senior notes that were issued in a private placement in October 2013. The exchange offer satisfies Dominion Gas' obligations under a registration rights agreement entered into in connection with the issuance of the Dominion Gas 2013 Senior Notes. The exchange offer does not represent a new financing transaction and there will be no proceeds to Dominion Gas when the offer settles, which is expected to occur in August 2014.
	Convertible Securities
	At June 30, 2014, Dominion had $36 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 June 30, 2014, the conversion rate had been adjusted, primarily due to individual dividend payments above the level paid at issuance, to 30.1180 shares of common stock per $1,000 principal amount of senior notes, which represents a conversion price of $33.20. If the outstanding notes as of June 30, 2014 were all converted, it would result in the issuance of approximately 550,000 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 and second quarters of 2014, the senior notes were eligible for conversion and approximately $7 million of the notes were converted by holders into $7 million of common stock. The senior notes are eligible for conversion during the third 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.
	Remarketable Subordinated Notes
	In July 2014, Dominion issued $1 billion of 2014 Series A 6.375% Equity Units, initially in the form of Corporate Units. The Corporate Units are listed on the NYSE under the symbol DCUC.
	Each Corporate Unit consists of a stock purchase contract and 1/20 interest in a RSN issued by Dominion. The stock purchase contracts obligate the holders to purchase shares of Dominion common stock at a future settlement date prior to the relevant RSN maturity date. The purchase price to be paid under the stock purchase contracts is $50 per Corporate Unit and the number of shares to be purchased will be determined under a formula based upon the average closing price of Dominion common stock near the settlement date. The RSNs are pledged as collateral to secure the purchase of common stock under the related stock purchase contracts.
	Dominion makes quarterly interest payments on the RSNs and quarterly contract adjustment payments on the stock purchase contracts, at the rates described below. Dominion may defer payments on the stock purchase contracts and the RSNs for one or more consecutive periods but generally not beyond the purchase contract settlement date. If payments are deferred, Dominion may not make any cash distributions related to its capital stock, including dividends, redemptions, repurchases, liquidation payments or guarantee payments. Also, during the deferral period, Dominion may not make any payments on or redeem or repurchase any debt securities that are equal in right of payment with, or subordinated to, the RSNs.
	Under the terms of the stock purchase contracts, assuming no anti-dilution or other adjustments, Dominion will issue between 11.5 million and 14.3 million shares of its common stock in July 2017. A total of 17.75 million shares of Dominion's common stock has been reserved for issuance in connection with the stock purchase contracts.
	Selected information about Dominion's 2014 Equity Units is presented below:
	Issuance Date	Units Issued	Total Net Proceeds			Total Long-term Debt			RSN Annual Interest Rate		Stock Purchase Contract Annual Rate		Stock Purchase Settlement Date	RSN Maturity Date
	(millions, except interest rates)

Commitments and Contingencies	'
	Commitments and Contingencies
	As a result of issues generated in the ordinary course of business, the Companies 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 the Companies' financial position, liquidity or results of operations.
	Environmental Matters
	The Companies 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 the Companies' 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. A 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 April 2014, the U.S. Supreme Court issued a decision upholding CSAPR by reversing and remanding the D.C. Circuit’s decision vacating the rule. The decision, however, did not lift the stay of CSAPR, and CAIR continues to remain in effect. In June 2014, the EPA filed a motion asking the U.S. Court of Appeals for the D.C. Circuit to lift the stay of CSAPR. Further, the EPA asked the court to toll the CSAPR compliance deadlines by three years, so that Phase 1 emissions budgets (which would have gone into effect in 2012 and 2013) would apply in 2015 and 2016, and Phase 2 emissions budgets would apply in 2017 and beyond. The cost to comply is not expected to be material. Future outcomes of any additional litigation and/or any 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. A number of the Companies' facilities are located within 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 August 2010, the EPA issued revised National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines. The rule was amended in March 2011 and January 2013. The rule establishes emission standards for control of hazardous air pollutants for engines at smaller facilities, known as area sources. As a result of these regulations, Dominion Gas installed emissions controls on several compressor engines. Dominion Gas has spent approximately $2 million to date and is evaluating further expenditures. Dominion Gas is unable to estimate the additional potential impacts on results of operations, financial condition and/or cash flows related to this matter.
	In August 2012, the EPA issued the first NSPS impacting the natural gas production and gathering sectors and made revisions to the NSPS for natural gas processing and transmission facilities. These rules establish equipment performance specifications and emissions standards for control of volatile organic chemical emissions for natural gas production wells, tanks, pneumatic controllers, and compressors in the upstream sector. Compliance with these rules is required for installations and wells constructed or reconstructed after August 23, 2011. The cost to comply with the NSPS will depend on the number of new wells and new equipment installations subject to the rule; therefore, Dominion Gas is unable to estimate the potential impacts on results of operations, financial condition and/or cash flows related to this matter.
	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 May 2014, the EPA published final regulations under Section 316(b) of the CWA that govern existing facilities and new units at existing facilities that employ a cooling water intake structure and that have flow levels exceeding a minimum threshold. The rule establishes a national standard for impingement based on seven compliance options, but forgoes the creation of a single technology standard for entrainment. Instead, the EPA has delegated entrainment technology decisions to state regulators. State regulators are to make case-by-case entrainment technology determinations after an examination of five mandatory facility-specific factors, including a social cost-benefit test, and six optional facility-specific factors. The rule governs all electric generating stations with water withdrawals above two MGD, with a heightened entrainment analysis for those facilities over 125 MGD. Dominion and Virginia Power have 14 and 11 facilities, respectively, that may be subject to the final regulations. Dominion anticipates that it will have to install impingement control technologies at many of these stations that have once-through cooling systems. Dominion and Virginia Power are currently evaluating the need or potential for entrainment controls under the final rule as these decisions will be made on a case-by-case basis after a thorough review of detailed biological, technology, cost and benefit studies. While the impacts of this rule could be material to Dominion's and Virginia Power's results of operations, financial condition and/or cash flows, the existing regulatory framework in Virginia provides rate recovery mechanisms that could substantially mitigate any such impacts for Virginia Power.
	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, Virginia Power, or Dominion Gas 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, Virginia Power, or Dominion Gas 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, and 12 of which pertain to Dominion Gas. 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 the Companies 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. 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 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 emissions from stationary sources under the CAA's permitting programs. In June 2014, the U.S. Supreme Court ruled that the EPA lacked the authority under the CAA to require PSD or Title V permits for stationary sources based solely on GHG emissions. However, the Court upheld the EPA’s ability to require BACT for GHG for sources that are otherwise subject to PSD or Title V permitting for conventional pollutants. Due to uncertainty regarding what actions states may take to amend their existing regulations and what action the EPA ultimately takes to address the Court ruling, the Companies cannot predict the impact to operations at this time.
	In July 2011, the EPA signed a final rule deferring the need for PSD 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 PSD and Title V applicability thresholds, including those for the application of BACT.  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.
	Legal Matters
	Dominion Gas is the defendant in a number of lawsuits and claims involving unrelated incidents of property damage and personal injury. Due to the uncertainty surrounding these matters, Dominion Gas is unable to make an estimate of the potential financial statement impacts; however, they could have a material impact on results of operations, financial condition and/or cash flows.
	Following the completion of the Appalachian Gateway Project in 2012, DTI received multiple change order requests and other claims for additional payments from a pipeline contractor for the project. In July 2013, DTI filed a complaint in U.S. District Court, Eastern District of Virginia for breach of contract, accounting and declaratory relief. The contractor filed a motion to dismiss, or in the alternative, a motion to transfer venue to Pennsylvania and/or West Virginia, where the pipelines were constructed. DTI filed an opposition to the contractor’s motion in August 2013. In November 2013, the court granted the contractor’s motion on the basis that DTI must first comply with the dispute resolution process. Pursuant to the ruling, DTI intends to mediate the matter. This case is pending. DTI has accrued a liability of approximately $6 million for this matter. Dominion Gas cannot currently estimate additional financial statement impacts, but there could be a material impact to its financial condition and/or cash flows.
	Cove Point
	In April 2013, Cove Point filed an application with the Maryland Commission for a CPCN to authorize the construction of an electric generating station needed to power the proposed liquefaction equipment. In May 2014, the Maryland Commission granted a CPCN authorizing the construction of such generating station. The CPCN is contingent upon Cove Point receiving FERC approval for the liquefaction project and will obligate Cove Point to make payments over time totaling approximately $48 million to the Maryland Strategic Energy Investments Fund and Maryland low income energy assistance programs. In June 2014, a party filed a notice of petition for judicial review of the CPCN with the Circuit Court for Baltimore City in Maryland. This matter is currently pending.
	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 Dominion and Virginia Power are discussing with the NRC any further actions that will be required for their plants. 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.
	Spent Nuclear Fuel
	Dominion and Virginia Power entered into contracts with the DOE for the disposal of spent nuclear fuel under provisions of the Nuclear Waste Policy Act of 1982. The DOE failed to begin accepting the spent fuel on January 31, 1998, the date provided by the Nuclear Waste Policy Act and by Dominion’s and Virginia Power's contracts with the DOE. Dominion and Virginia Power have previously received damages award payments and settlement payments related to these contracts and have entered into settlement agreements that resolved claims for damages incurred through December 31, 2010, and also provide for periodic payments after that date for damages incurred through December 31, 2013.
	In the second quarter of 2014, the government formally accepted offers of settlement from Virginia Power and Dominion to resolve claims for damages incurred at North Anna and Surry in the amount of approximately $27 million for the period of January 1, 2011 through December 31, 2012 and at Millstone in the amount of approximately $17 million for the period July 1, 2012 through June 30, 2013. Payment is expected by the third quarter of 2014. Dominion expects that the government will formally accept an offer of settlement for resolution of claims incurred at Kewaunee in the amount of approximately $5 million for the period January 1 through December 31, 2013, with payment expected in the third or fourth quarter of 2014.
	By mutual agreement of the parties, the settlement agreements are extendable to provide for resolution of damages incurred after 2013. The settlement agreements for the Surry, North Anna and Millstone plants have been extended to provide for periodic payments for damages incurred through December 31, 2016. Possible extension of the Kewaunee settlement agreement is being evaluated.
	Dominion and Virginia Power continue to recognize receivables for certain spent nuclear fuel-related costs that they believe are probable of recovery from the DOE. Dominion’s receivables for spent nuclear fuel-related costs totaled $92 million and $79 million at June 30, 2014 and December 31, 2013, respectively. Virginia Power’s receivables for spent nuclear fuel-related costs totaled $60 million and $50 million at June 30, 2014 and December 31, 2013, respectively.
	Pursuant to a November 2013 decision of the U.S Court of Appeals for the D.C. Circuit, in January 2014, the Secretary of the DOE sent a recommendation to the U.S. Congress to adjust to zero the current fee of $1 per MWh for electricity paid by civilian nuclear power generators for disposal of spent nuclear fuel. The processes specified in the Nuclear Waste Policy Act for adjustment of the fee have been completed, and as of May 16, 2014, Dominion and Virginia Power are no longer required to pay the waste fee. In 2014, Dominion and Virginia Power recognized fees of $16 million and $10 million, respectively.
	Dominion and Virginia Power will continue to manage their spent fuel until it is accepted by the DOE.
	Guarantees
	Dominion
	At June 30, 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 June 30, 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 June 30, 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 June 30, 2014, Dominion had issued the following subsidiary guarantees:
		Stated Limit		Value(1)
	(millions)
	Subsidiary debt(2)	$	27	$	27
	Commodity transactions(3)	3,040		468
	Nuclear obligations(4)	236		91

	Solar(6)	169		397
	Other(7)	521		84
	Total	$	4,328	$	1,067
	-1	Represents the estimated portion of the guarantee's stated limit that is utilized as of June 30, 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, Dominion Gas 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 (in the event of a prolonged outage) and Kewaunee, respectively, 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 EPC 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. Also includes a guarantee entered into by DEI on behalf of a subsidiary to facilitate the acquisition and development of a solar project.
	-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 June 30, 2014, Dominion had purchased $129 million of surety bonds, including $60 million at Virginia Power and $31 million at Dominion Gas, and authorized the issuance of letters of credit by financial institutions of $115 million, including $18 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
	The Companies' accounting policies for credit risk are discussed in Note 23 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 and Note 19 in Exhibit 99.11(b) to Dominion Gas’ Current Report on Form 8-K dated June 26, 2014.
	At June 30, 2014, Dominion's credit exposure totaled $122 million. Of this amount, investment grade counterparties, including those internally rated, represented 59%. 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 June 30, 2014 and December 31, 2013, Dominion would have been required to post an additional $79 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 $5 million and $76 million in collateral at June 30, 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 June 30, 2014 and December 31, 2013 was $161 million and $169 million, respectively, which does not include the impact of any offsetting asset positions. Credit-related contingent provisions for Virginia Power and Dominion Gas were not material as of June 30, 2014 and December 31, 2013. See Note 9 for further information about derivative instruments.
	Dominion Gas
	In the second quarter of 2014, DTI provided service to 234 customers with approximately 94% of its storage and transportation revenue being provided through firm services. The ten largest customers provided approximately 42% of the total storage and transportation revenue and the 30 largest provided approximately 75% of the total storage and transportation revenue. Approximately 97% of the transmission capacity under contract on DTI’s pipeline is subscribed with long-term contracts (two years or greater). The remaining 3% is contracted on a year-to-year basis. Less than 1% of firm transportation capacity is currently unsubscribed. All storage services are subscribed under long-term contracts.
	East Ohio distributes natural gas to residential, commercial and industrial customers in Ohio using rates established by the Ohio Commission. Approximately 98% of East Ohio revenues are derived from its jurisdictional gas services. East Ohio’s bad debt risk is mitigated by the regulatory framework established by the Ohio Commission. See Note 12 for further information about Ohio’s PIPP and UEX Riders that mitigate East Ohio’s overall credit risk.

	In addition to the operating segments above, the Companies also report a Corporate and Other segment.
	Dominion
	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 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 the electric retail energy marketing business has been included in the Corporate and Other Segment of Dominion for 2014 first quarter results of operations.
	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 six months ended June 30, 2014, Dominion reported an after-tax net expense of $430 million for specific items in the Corporate and Other segment, with $402 million of these net expenses attributable to its operating segments. In the six months ended June 30, 2013, Dominion reported an after-tax net expense of $134 million for specific items in the Corporate and Other segment, with $131 million of these net expenses 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;
	•	A $287 million ($191 million after-tax) charge associated with Virginia legislation enacted in April 2014 relating to the development of a third nuclear unit located at North Anna and offshore wind facilities, attributable to Dominion Generation; 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 expense for specific items in 2013 primarily related to the impact of the following items:
	•	A $118 million ($69 million after-tax) net loss from discontinued operations of Brayton Point and Kincaid, including debt extinguishment of $64 million ($38 million after-tax) related to the pending sale, impairment charges of $48 million ($28 million after-tax), and a $6 million ($3 million after-tax) loss from operations, attributable to Dominion Generation;
	•	A $107 million ($57 million after-tax) net loss, including a $55 million ($33 million after-tax) impairment charge related to certain natural gas infrastructure assets and a $52 million ($24 million after-tax) loss related to the producer services business discussed above, attributable to Dominion Energy; and
	•	A $28 million ($17 million after-tax) charge primarily reflecting severance pay and other benefits related to workforce reductions attributable to all segments; partially offset by
	•	A $51 million ($31 million after-tax) net gain on investments held in nuclear decommissioning trust funds, attributable to Dominion Generation.

-2	Reflects deferrals under the electric transmission FERC formula rate and the deferral of costs associated with certain current and prospective rider projects for Virginia Power. Reflects deferrals of costs associated with certain current and prospective rider projects for Dominion Gas. See Note 12 for more information.
-3	Legislation enacted in Virginia in April 2014 requires Virginia Power to defer operation and maintenance costs incurred in connection with the refueling of any nuclear-powered generating plant. These deferred costs will be amortized over the refueling cycle, but in no case for more than 18 months.
-4	Reflects unrecovered gas costs at regulated gas operations, which are recovered through filings with the applicable regulatory authority.
-5	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.
-6	Current regulatory assets are presented in other current assets in the Companies' Consolidated Balance Sheets.
-7	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.
-8	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.
-9	Under PIPP, eligible customers can make reduced payments 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.
-10	Current regulatory liabilities are presented in other current liabilities in the Companies' Consolidated Balance Sheets.
-11	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.
-12	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.
-13	Represents East Ohio's deferrals for the UEX Rider which are recovered through rates which are filed annually. Most of East Ohio's bad debt expense is recovered either through the UEX Rider or the PIPP Rider.
-14	Primarily reflects costs recognized in excess of amounts included in regulated rates charged by Dominion Gas' regulated gas operations before rates were updated to reflect a change in accounting method for other postretirement benefit costs.
-15	Noncurrent regulatory liabilities are presented in other deferred credits and other liabilities in Dominion Gas' Consolidated Balance Sheets.

[2]	Reflects deferrals under the electric transmission FERC formula rate and the deferral of costs associated with certain current and prospective rider projects for Virginia Power. Reflects deferrals of costs associated with certain current and prospective rider projects for Dominion Gas. See Note 12 for more information.
[3]	Legislation enacted in Virginia in April 2014 requires Virginia Power to defer operation and maintenance costs incurred in connection with the refueling of any nuclear-powered generating plant. These deferred costs will be amortized over the refueling cycle, but in no case for more than 18 months.
[4]	Reflects unrecovered gas costs at regulated gas operations, which are recovered through filings with the applicable regulatory authority.
[5]	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.
[6]	Current regulatory assets are presented in other current assets in the Companies' Consolidated Balance Sheets.
[7]	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.
[8]	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.
[9]	Dominionbs Consolidated Balance Sheet at DecemberB 31, 2013 has been derived from the audited Consolidated Financial Statements at that date.
[10]	Under PIPP, eligible customers can make reduced payments 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.
[11]	Current regulatory liabilities are presented in other current liabilities in the Companies' Consolidated Balance Sheets.
[12]	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.
[13]	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.
[14]	Virginia Powerbs Consolidated Balance Sheet at DecemberB 31, 2013 has been derived from the audited Consolidated Financial Statements at that date.
[15]	Represents East Ohio's deferrals for the UEX Rider which are recovered through rates which are filed annually. Most of East Ohio's bad debt expense is recovered either through the UEX Rider or the PIPP Rider.
[16]	Primarily reflects costs recognized in excess of amounts included in regulated rates charged by Dominion Gas' regulated gas operations before rates were updated to reflect a change in accounting method for other postretirement benefit costs.
[17]	Dominion Gasb Consolidated Balance Sheet at DecemberB 31, 2013 has been derived from the Audited Consolidated Financial Statements at that date.
[18]	Noncurrent regulatory liabilities are presented in other deferred credits and other liabilities in Dominion Gas' Consolidated Balance Sheets.
