Other important factors that could cause such material differences include, but are not limited to, the following:

(1) the occurrence of any event, change or other circumstances that could give rise to the failure by SCANA to consummate the proposed merger with Dominion Energy; (2) the ability of SCE&G to recover through rates the costs expended the Nuclear Project, and a reasonable return on those costs, under the abandonment provisions of the BLRA or through other means; (3) uncertainties relating to the bankruptcy filing by WEC and WECTEC; (4) further changes in tax laws and realization of tax benefits and credits, and the ability or inability to realize credits and deductions, particularly in light of the abandonment of the Nuclear Project; (5) legislative and regulatory actions, particularly changes related to electric and gas services, rate regulation, regulations governing electric grid reliability and pipeline integrity, environmental regulations including any imposition of fees or taxes on carbon emitting generating facilities, the BLRA, and any actions affecting the abandonment of the Nuclear Project; (6) current and future litigation, including particularly litigation or government investigations or actions involving or arising from the construction or abandonment of the Nuclear Project or arising from the proposed merger with Dominion Energy; (7) the impact of any decision by SCANA to pay quarterly dividends to its shareholders or the reduction, suspension or elimination of the amount thereof; (8) the results of short- and long-term financing efforts, including prospects for obtaining access to capital markets and other sources of liquidity, and the effect of rating agency actions on the cost of and access to capital and sources of liquidity of SCANA and its subsidiaries (the Company); (9) the ability of suppliers, both domestic and international, to timely provide the labor, secure processes, components, parts, tools, equipment and other supplies needed which may be highly specialized or in short supply, at agreed upon quality and prices, for our construction program, operations and maintenance; (10) the results of efforts to ensure the physical and cyber security of key assets and processes; (11) changes in the economy, especially in areas served by subsidiaries of SCANA; (12) the impact of competition from other energy suppliers, including competition from alternate fuels in industrial markets; (13) the impact of conservation and demand side management efforts and/or technological advances on customer usage; (14) the loss of electricity sales to distributed generation, such as solar photovoltaic systems or energy storage systems; (15) growth opportunities for SCANA’s regulated and other subsidiaries; (16) the effects of weather, especially in areas where the generation and transmission facilities of the Company are located and in areas served by SCANA’s subsidiaries; (17) changes in SCANA’s or its subsidiaries’ accounting rules and accounting policies; (18) payment and performance by counterparties and customers as contracted and when due; (19) the results of efforts to license, site, construct and finance facilities, and to receive related rate recovery, for generation and transmission; (20) the results of efforts to operate the Company's electric and gas systems and assets in accordance with acceptable performance standards, including the impact of additional distributed generation; (21) the availability of fuels such as coal, natural gas and enriched uranium used to produce electricity; the availability of purchased power and natural gas for distribution; the level and volatility of future market prices for such fuels and purchased power; and the ability to recover the costs for such fuels and purchased power; (22) the availability of skilled, licensed and experienced human resources to properly manage, operate, and grow the Company’s businesses, particularly in light of uncertainties with respect to legislative and regulatory actions surrounding recovery of Nuclear Project costs and the announced potential merger; (23) labor disputes; (24) performance of SCANA’s pension plan assets and the effect(s) of associated discount rates; (25) inflation or deflation; (26) changes in interest rates; (27) compliance with regulations; (28) natural disasters, man-made mishaps and acts of terrorism that directly affect our operations or the regulations governing them; and (29) the other risks and uncertainties described from time to time in the reports filed by SCANA or SCE&G with the SEC.

SCANA Corporation and Subsidiaries

South Carolina Electric & Gas Company and Affiliates

Notes to Condensed Consolidated Financial Statements

(Unaudited)

The following unaudited notes to the condensed consolidated financial statements are a combined presentation. Except as otherwise indicated herein, each note applies to the Company and Consolidated SCE&G; however, Consolidated SCE&G makes no representation as to information relating solely to SCANA Corporation or its subsidiaries (other than Consolidated SCE&G).

The following condensed notes should be read in conjunction with the Notes to Consolidated Financial Statements appearing in each company's Annual Report on Form 10-K for the year ended December 31, 2017, which also were a combined presentation. These are interim financial statements and, due to the seasonality of each company's business and matters that may occur during the rest of the year, including the matters described in Note 10 under Impairment Considerations, the amounts reported in the Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Comprehensive Income are not necessarily indicative of amounts expected for the full year.  In the opinion of management of the respective companies, the information furnished herein reflects all adjustments, all of a normal recurring nature, which are necessary for a fair statement of the results for the interim periods reported. In addition, the preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation and Variable Interest Entities

     The condensed consolidated financial statements of the Company include, after eliminating intercompany balances and transactions, the accounts of the parent holding company and each of its subsidiaries, including Consolidated SCE&G. Accordingly, discussions regarding the Company's financial results necessarily include the results of Consolidated SCE&G.

SCE&G has determined that it has a controlling financial interest in each of GENCO and Fuel Company (which are considered to be VIEs) and, accordingly, Consolidated SCE&G's condensed consolidated financial statements include the accounts of SCE&G, GENCO and Fuel Company. The equity interests in GENCO and Fuel Company are held solely by SCANA, SCE&G’s parent. As a result, GENCO’s and Fuel Company’s equity and results of operations are reflected as noncontrolling interest in Consolidated SCE&G’s condensed consolidated financial statements.

GENCO owns a coal-fired electric generating station with a 605 MW net generating capacity (summer rating). GENCO’s electricity is sold, pursuant to a FERC-approved tariff, solely to SCE&G under the terms of a power purchase agreement and related operating agreement. The effects of these transactions are eliminated in consolidation. Substantially all of GENCO’s property (carrying value of approximately $500 million) serves as collateral for its long-term borrowings. Fuel Company acquires, owns and provides financing for SCE&G’s nuclear fuel, certain fossil fuels and emission and other environmental allowances. See also Note 5.

Income Statement Presentation

Revenues and expenses arising from regulated businesses and, in the case of the Company, the retail natural gas marketing business (including those activities of segments described in Note 11) are presented within Operating Income, and other activities are presented within Other Income (Expense).

Asset Management and Supply Service Agreement

PSNC Energy, a subsidiary of SCANA, utilizes an asset management and supply service agreement with a counterparty for certain natural gas storage facilities.  Such counterparty held, through an agency relationship, 32% and 39% of PSNC Energy’s natural gas inventory at March 31, 2018 and December 31, 2017, respectively, with a carrying value of $5.5 million and $11.5 million, respectively.  Under the terms of this agreement, PSNC Energy receives storage asset management feesof which 75% are credited to customers. This agreement expires on March 31, 2019.

18

Earnings Per Share

The Company computes basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. When applicable, the Company computes diluted earnings per share using this same formula, after giving effect to securities considered to be dilutive potential common stock utilizing the treasury stock method.

Reclassifications

In the statement of operations, amounts previously reported under the captions “Other income”, “Other expense” and “Allowance for equity funds used during construction” have been combined into a single caption titled “Other Income (Expense), Net”. Details of the composition of this caption are described in Note 12. Also, the subtotal captioned “Total Other Expense” that previously appeared on the statements of operations has been eliminated.

New Accounting Matters

Recently Adopted

In the first quarter of 2018, the Company and Consolidated SCE&G adopted the following accounting guidance, as applicable, issued by the FASB. The adoption of this guidance had no impact on their respective financial statements except as indicated.

• In January 2017, the FASB issued accounting guidance to simplify the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. The guidance is effective for years beginning in 2020, though early adoption after January 1, 2017 is allowed. The Company adopted this guidance on January 1, 2018, and its adoption had no impact on its financial statements.

• Effective January 1, 2018, the Company and Consolidated SCE&G adopted new accounting guidance for revenue arising from contracts with customers. This guidance uses a five-step analysis in determining when and how revenue is recognized, and requires that revenue recognition depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. As permitted, this guidance was adopted using the modified retrospective method whereby amounts and disclosures for prior periods are not restated. Revenue recognition patterns did not change as a result of adopting this guidance, and no cumulative effect adjustment to Retained Earnings was required. For additional required disclosures, see Note 3.

• Effective January 1, 2018, the Company and Consolidated SCE&G adopted accounting guidance that changed the required presentation of net periodic pension and postretirement benefit costs. As a result, net periodic pension and postretirement benefit costs have been separated into their service cost components and non-service cost components. Service cost components continue to be included within operating income and are presented in the same line item as other compensation costs arising from services rendered by employees during the period. Non-service cost components are now excluded from operating income. This guidance has been applied on a retrospective basis for the presentation of the service cost components and other components, and resulted in the following changes to the amounts reported in 2017.

For the three months ended March 31, 2017
Increase (Decrease) Millions of dollars	The Company			Consolidated SCE&G
Other operation and maintenance	$	(4	)	$	(4	)
Total Operating Expenses	(4		)	(4		)
Operating Income	4			4
Other Income (Expense), Net	(4		)	(4		)

In addition, this guidance limits eligibility for capitalization of net periodic pension and postretirement benefit costs to only the service cost components, and requires this change to be applied prospectively. Accordingly, no reclassifications were made related to the capitalization of service costs, and the adoption of this guidance did not result in a material impact on the Company’s and Consolidated SCE&G’s respective financial statements. Amounts

19

which otherwise would have been capitalized to plant accounts under prior guidance are now being deferred within regulatory assets.

• Guidance issued in January 2016 changed how entities measure certain equity investments and financial liabilities, among other things. Entities were required to record a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year in which the guidance was effective, with certain exceptions. The Company and Consolidated SCE&G adopted this guidance when required in the first quarter of 2018 and its adoption did not have a significant impact on their respective financial statements.

• Guidance issued in August 2016 is intended to reduce diversity in cash flow statement classification related to certain transactions, and entities must apply the guidance retrospectively to all periods presented. The adoption of this guidance had no impact on the financial statements of the Company and Consolidated SCE&G.

• Guidance issued in November 2016 clarified how restricted cash should be presented on the statement of cash flows, and entities were to apply the guidance retrospectively to all periods presented. The adoption of this guidance had no impact on the financial statements of the Company and Consolidated SCE&G.

Pending Adoption

The Company and Consolidated SCE&G will adopt the following accounting guidance issued by the FASB when indicated below.

In February 2016, the FASB issued accounting guidance related to the recognition, measurement and presentation of leases. The guidance applies a right-of-use model and, for lessees, requires all leases with a duration over 12 months to be recorded on the balance sheet, with the rights of use treated as assets and the payment obligations treated as liabilities. Further,

and without consideration of any regulatory accounting requirements which may apply, depending primarily on the nature of the assets and the relative consumption of them, lease costs will be recognized either through the separate amortization of the right-of-use asset and the recognition of the interest cost related to the payment obligation, or through the recording of a combined straight-line rental expense. For lessors, the guidance calls for the recognition of income either through the derecognition of assets and subsequent recording of interest income on lease amounts receivable, or through the recognition of rental income on a straight-line basis, also depending on the nature of the assets and relative consumption. In the first quarter of 2018, FASB amended this accounting guidance to clarify that land easements are within the scope of the new guidance and to provide an optional transition practical expedient, that the Company and Consolidated SCE&G currently intend to adopt, that allows adopters to not evaluate under the new guidance existing or expired land easements that were not previously accounted for as leases. FASB also approved a new transition option in the first quarter of 2018, that the Company and Consolidated SCE&G are evaluating, that will allow the new standard to be adopted without revising comparative period reporting or disclosures. The new guidance is effective for years beginning in 2019, and the Company and Consolidated SCE&G do not anticipate that its adoption will impact their respective financial statements other than increasing amounts reported for assets and liabilities on the balance sheet and changing the location on their respective statements of operations where certain expenses are recorded. No impact on net income is expected. The identification and analysis of leasing and related contracts to which the guidance might be applicable continues. In addition, the Company and Consolidated SCE&G have begun implementation of a third party software tool that will assist with initial adoption and ongoing compliance. Preliminary system configuration has been completed and data from certain leases are being entered.

In June 2016, the FASB issued accounting guidance requiring the use of a current expected credit loss impairment model for certain financial instruments. The new model is applicable to trade receivables and most debt instruments, among other financial instruments, and in certain instances may result in impairment losses being recognized earlier than under current guidance. The Company and Consolidated SCE&G must adopt this guidance beginning in 2020, including interim periods, though the guidance may be adopted in 2019. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective financial statements.

In August 2017, the FASB issued accounting guidance intended to simplify the application of hedge accounting. Among other things, the new guidance will enable more hedging strategies to qualify for hedge accounting, will allow entities more time to perform an initial assessment of hedge effectiveness, and will permit an entity to perform a qualitative assessment of effectiveness for certain hedges instead of a quantitative one. For cash flow hedges that are highly effective, all changes in the fair value of the derivative hedging instrument will be recorded in other comprehensive income and will be reclassified to earnings in the same period that the hedged item impacts earnings. Fair value hedges will continue to be recorded in current earnings, and any ineffectiveness will impact the income statement. In addition, changes in the fair value of a derivative will be

20

recorded in the same income statement line as the earnings effect of the hedged item, and additional disclosures will be required related to the effect of hedging on individual income statement line items. The guidance must be applied to all outstanding instruments using a modified retrospective method, with any cumulative effect adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2019, though early adoption is permitted, and have not determined what impact such adoption will have on their respective financial statements.

In February 2018, the FASB issued accounting guidance allowing entities to reclassify from AOCI to retained earnings any amounts for stranded tax effects resulting from the Tax Act. The guidance must be applied either in the period of adoption or retrospectively to each period in which the effect of the change was recognized. The Company and Consolidated SCE&G must adopt this guidance beginning in 2019, including interim periods, though the guidance may be adopted earlier. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective statements of financial position. No impact is expected on statements of operations or cash flows.

2.RATE AND OTHER REGULATORY MATTERS

Rate Matters

Tax Act Regulatory Proceedings

The Tax Act contained provisions that lowered the federal corporate tax rate from 35% to 21% effective January 1, 2018. In response, the SCPSC and the NCUC have sought information from utilities under their respective jurisdictions that would disclose the impact of the Tax Act on their individual company's operations and would propose procedures for changing customer rates to reflect those impacts. SCE&G and PSNC Energy provided to their respective commissions the requested information. The ORS filed a petition with the SCPSC that, among other things, requested that the SCPSC order that rates in effect as of January 1, 2018, be subject to refund so that ratepayers receive the benefit of the tax law changes as of January 1, 2018. The ORS has made subsequent filings with the SCPSC making specific recommendations for how it should direct SCE&G to account for the effects of the Tax Act and for the accrual of interest on deferred amounts until new customer rates are made effective. On April 25, 2018, the SCPSC issued an order that requires utilities to track and defer as a regulatory liability the effects resulting from the Tax Act.

SCE&G and PSNC Energy cannot determine when their respective commissions will take final action on this matter or what form that action will take. In the first quarter of 2018, estimates of income tax amounts charged through customer rates that relate to the effects of the Tax Act are being deferred as amounts subject to refund. Such deferrals include the accrual of estimated carrying costs. Such estimates totaled $40.0 million for the Company, of which $33.2 million was attributable to Consolidated SCE&G, and are included within Customer Deposits and Customer Prepayments on their respective condensed consolidated balance sheets. In addition, as further discussed under Regulatory Assets and Regulatory Liabilities below, certain accumulated deferred income taxes contained within regulatory liabilities represent excess deferred income taxes arising from the remeasurement of deferred income taxes upon the enactment of the Tax Act. Certain of these amounts are protected under normalization regulations and will be amortized over the remaining lives of related property, and certain of these amounts will be amortized to the benefit of customers over a prescribed period as instructed by regulators.

Electric - Cost of Fuel

On April 25, 2018, the SCPSC approved SCE&G’s proposal to increase the total fuel cost component of retail electric rates. Specifically, the SCPSC approved SCE&G’s increase to certain environmental, avoided capacity and DER cost components and SCE&G’s agreement to maintain its base fuel component to produce a projected under-recovered balance of approximately $1.3 million at the end of the 12-month period beginning with the first billing cycle of May 2018. This projected under-recovered balance includes the effect of offsetting fuel costs recovery with the gains realized from the settlement of certain interest rate derivatives. SCE&G also agreed to recover, over a 12-month period beginning with the first billing cycle of May 2018, projected DER program costs of approximately $29.3 million.

Electric - Base Rates

In January 2018, SCE&G requested in its annual DSM Programs filing to recover approximately $33.0 million of costs and net lost revenues associated with DSM programs, along with an incentive to invest in such programs. On April 25, 2018, the SCPSC approved SCE&G’s request effective beginning with the first billing cycle of May 2018.

21

Electric - BLRA and Joint Petition

On January 12, 2018, SCE&G and Dominion Energy filed with the SCPSC the Joint Petition for review and approval of a proposed business combination whereby SCANA would become a wholly-owned subsidiary of Dominion Energy. In the Joint Petition, approval of a customer benefits plan and a cost recovery plan for the Nuclear Project is also sought. Key provisions of this Joint Petition are summarized at Note 10. A hearing on this matter has not yet been scheduled.

On January 19, 2018, the ORS filed a report with the SCPSC in response to the SCPSC's order for a thorough inspection and audit of SCE&G's statements regarding potential adverse effects that could result from the removal of annual BLRA revenues. SCE&G subsequently filed responses to the ORS report. On January 31, 2018, the SCPSC ordered the ORS to complete the previously ordered thorough audit, inspection and examination of SCE&G's accounting records by March 30, 2018, encouraged them to employ the assistance of a utility financial professional if needed, and indicated that a request by the ORS for an extension of time would not be considered unreasonable. On February 7, 2018, the ORS requested clarification of the SCPSC's January 31, 2018 order. On February 15, 2018, the SCPSC instructed the ORS to evaluate a total of eight different scenarios to be included in its report and instructed the ORS to inform them by March 2, 2018 whether the ORS needed additional time to complete its work, By letter dated March 2, 2018, the ORS informed the SCPSC that it anticipates completing its scope of work in June 2018.

Gas - PSNC Energy

The NCUC has authorized PSNC Energy to use a tracker mechanism to recover the incurred capital investment and associated costs of complying with federal standards for pipeline integrity and safety requirements that are not in current base rates. PSNC Energy has filed biannual applications to adjust its rates for this purpose, and the NCUC has approved those applications for the incremental annual revenue requirements, as follows:

Rates Effective	Incremental Increase
March 1, 2017	$1.9 million
September 1, 2017	$0.7 million
March 1, 2018	$14.7 million

Regulatory Assets and Regulatory Liabilities

Rate-regulated utilities recognize in their financial statements certain revenues and expenses in different periods than do other enterprises.  As a result, the Company and Consolidated SCE&G have recorded regulatory assets and regulatory liabilities which are summarized in the following tables. Except for certain unrecovered nuclear project costs and other unrecovered plant, substantially all regulatory assets are either explicitly excluded from rate base or are effectively excluded from rate base due to their being offset by related liabilities.

	The Company				Consolidated SCE&G
Millions of dollars	March 31, 2018		December 31, 2017		March 31, 2018		December 31, 2017
Regulatory Assets:
Unrecovered Nuclear Project costs	$	3,966	$	3,976	$	3,966	$	3,976

Regulatory Liabilities:
Monetization of guaranty settlement	$	1,094	$	1,095	$	1,094	$	1,095
Accumulated deferred income taxes	1,072		1,076		914		914
Asset removal costs	763		757		530		527
Deferred gains on interest rate derivatives	79		131		79		131
Total Regulatory Liabilities	$	3,008	$	3,059	$	2,617	$	2,667

Regulatory assets for unrecovered Nuclear Project costs have been recorded based on such amounts not being probable of loss in accordance with the accounting guidance on abandonments, whereas the other regulatory assets have been recorded based on the probability of their recovery. All regulatory assets represent incurred costs that may be deferred under applicable GAAP for regulated operations. The SCPSC, the NCUC or the FERC has reviewed and approved through specific orders certain of the items shown as regulatory assets. In addition, regulatory assets include, but are not limited to, certain costs which have not been specifically approved for recovery by one of these regulatory agencies, including unrecovered nuclear project costs that are the subject of regulatory proceedings as further discussed in Note 10. In recording such costs as regulatory assets, management believes the costs would be allowable under existing rate-making concepts that are embodied in rate orders or current state law. The costs are currently not being recovered, but are expected to be recovered through rates in future periods. In the future, as a result of deregulation, changes in state law, other changes in the regulatory environment or changes in accounting requirements or other adverse legislative or regulatory developments, the Company or Consolidated SCE&G could be required to write off all or a portion of its regulatory assets and liabilities. Such an event could have a material effect on the Company's and Consolidated SCE&G's financial statements in the period the write-off would be recorded.

Unrecovered Nuclear Project costs represents expenditures by SCE&G that have been reclassified from construction work in progress as a result of the decision to stop construction of Unit 2 and Unit 3 and to pursue recovery of costs under the abandonment provisions of the BLRA or through other regulatory means, net of an estimated impairment loss and of certain assets that have been or will be placed in service.

AROs and related funding represents the regulatory asset associated with the legal obligation to decommission and dismantle Unit 1 and conditional AROs related to generation, transmission and distribution properties, including gas pipelines. These regulatory assets are expected to be recovered over the related property lives and periods of decommissioning which may range up to approximately 107 years.

Employee benefit plan costs of the regulated utilities have historically been recovered as they have been recorded under GAAP. Deferred employee benefit plan costs represent amounts of pension and other postretirement benefit costs which were accrued as liabilities and treated as regulatory assets pursuant to FERC guidance, and costs deferred pursuant to specific SCPSC regulatory orders. SCE&G recovers deferred pension costs through utility rates of approximately $2 million annually for electric operations, which will end in 2044, and approximately $1 million annually for gas operations, which will end in 2027. The remainder of the deferred benefit costs are expected to be recovered through utility rates, primarily over average service periods of participating employees up to approximately 11 years.

Deferred losses or gains on interest rate derivatives represent (i) the effective portions of changes in fair value and payments made or received upon settlement of certain interest rate derivatives designated as cash flow hedges and (ii) the changes in fair value and payments made or received upon settlement of certain other interest rate derivatives not so designated. The amounts recorded with respect to (i) are expected to be amortized to interest expense over the lives of the underlying debt through 2043. The amounts recorded with respect to (ii) are expected to be similarly amortized to interest expense through 2065.

Other unrecovered plant represents the carrying value of coal-fired generating units, including related materials and supplies inventory, retired from service prior to being fully depreciated. Pursuant to SCPSC approval, SCE&G is amortizing these amounts through cost of service rates over the units' previous estimated remaining useful lives through approximately 2025. Unamortized amounts are included in rate base and are earning a current return.

DSM Programs represent SCE&G's deferred costs associated with electric demand reduction programs, and such deferred costs are currently being recovered over approximately five years through an approved rate rider. 

Pipeline integrity management costs represent operating costs incurred to comply with federal regulatory requirements related to natural gas pipelines. PSNC Energy is recovering costs totaling $4.1 million annually through 2021. PSNC Energy is

23

continuing to defer pipeline integrity costs, and as of March 31, 2018 costs of $30.6 million have been deferred pending future approval of rate recovery. SCE&G amortizes $1.9 million of such costs annually.

Environmental remediation costs represent costs associated with the assessment and clean-up of sites currently or formerly owned by SCE&G or PSNC Energy. SCE&G's remediation costs are expected to be recovered over periods of up to approximately 17 years, and PSNC Energy's remediation costs totaling $6.9 million are being recovered over a five year period that will end in 2021.

Deferred storm damage costs represent costs incurred in excess of amounts previously collected through SCE&G’s SCPSC-approved storm damage reserve, and for which SCE&G expects to receive future recovery through customer rates.

Various other regulatory assets are expected to be recovered through rates over varying periods through 2047.

Monetization of guaranty settlement represents proceeds received under or arising from the monetization of the Toshiba Settlement, net of certain expenses. The SCPSC is expected to determine how SCE&G's customers will realize the value of these net proceeds in connection with its consideration of the Request by the ORS and the Joint Petition (see Note 10).

Accumulated deferred income taxes contained within regulatory liabilities represent (i) excess deferred income taxes arising from the remeasurement of deferred income taxes upon the enactment of the Tax Act (certain of which are protected under normalization regulations and will be amortized over the remaining lives of related property, and certain of which will be amortized to the benefit of customers over a prescribed period as instructed by regulators) and (ii) deferred income taxes arising from investment tax credits, offset by (iii) deferred income taxes that arise from utility operations that have not been included in customer rates (a portion of which relate to depreciation and are expected to be recovered over the remaining lives of the related property which may range up to approximately 85 years).

Asset removal costs represent estimated net collections through depreciation rates of amounts to be incurred for the removal of assets in the future.

3.    REVENUE RECOGNITION

Identifying Revenue Streams and Related Performance Obligations

Operating Revenues

Operating revenues arise primarily from the sale and transmission of electricity and the sale and transportation of natural gas. Electric and Gas regulated revenues consist primarily of retail sales to residential, commercial and industrial customers under various tariff rates approved by state regulatory commissions. These tariff rates generally include charges for the energy consumed and a standard basic facilities or demand charge designed to recover certain fixed costs incurred to provide service to the customer. Tariff rates also include commission-approved regulatory mechanisms in the form of adjustments or riders, such as for weather normalization, fuel and environmental cost recovery, energy conservation programs, interruptible service and real time pricing provisions, among others. Electric revenues also include wholesale sales and transmission service, primarily to municipal customers and other service providers, under contracts or tariffs approved by the FERC.

Gas nonregulated revenues arise from natural gas sales at market-based rates. Such sales to residential and certain commercial customers include charges for natural gas delivered, at either variable or fixed prices, together with any applicable customer service charges, charges originating from an interstate pipeline company, and other incidental charges. The Company has determined that its gas marketing subsidiary serves as an agent for distribution services provided by a nonaffiliated company in its retail market. Accordingly, the pass-through charges to customers related to such services are not considered revenues. Sales to other commercial and to industrial customers include commodity and transportation charges for natural gas delivered at contracted rates, together with applicable fees for storage, injection, demand, and charges originating from one or more interstate pipeline companies.

Performance obligations which have not been satisfied by the Company or Consolidated SCE&G relate primarily to demand or standby service for natural gas. Demand or standby charges for natural gas arise when an industrial customer reserves capacity on assets controlled by the service provider and may use that capacity to move natural gas it has acquired from other suppliers. For all periods presented, the amount of revenue recognized by the Company and Consolidated SCE&G for these charges is equal to the amount of consideration they have a right to invoice, and corresponds directly to the value

24

transferred to the customer. As a result, amounts related to performance obligations that have not been fully satisfied are not disclosed.

Contracts governing the transactions above do not have a significant financing component. Also, due to the nature of the commodities underlying these transactions, no performance obligations arise for returns, refunds or warranties. In addition, taxes billed to customers are excluded from the transaction price. Such amounts are recorded as liabilities until they are remitted to the respective taxing authority and are not included in revenues or expenses in the statements of operations.

Non-Operating Revenues

Non-operating revenues are derived from the sale of appliances and water heaters, as well as from contracts covering the repair of certain appliances, wiring, plumbing and similar systems and fees received for such repairs from customers not under a repair contract. In addition, the portion of fees received under asset management agreements that regulators have recognized to be incentives for the Company and Consolidated SCE&G to engage in such transactions is recorded as non-operating revenues.

Revenues from sales are recorded when the appliance or water heater is delivered to the customer. Repair contract coverage fees are recorded when invoiced, generally on a monthly basis in advance of the period of coverage. Additional charges for service calls and non-covered repairs are billed and collected at the time service is rendered. Revenues from asset management agreements are recorded when the related fixed monthly amounts are due, which corresponds to timing of the value received by the customer.

The point at which the customer controls the use of a purchased product, or has obtained substantially all of the benefits from repair services, corresponds to when revenues are recorded and performance obligations are fulfilled. Contract assets arising from invoicing repair contract fees in advance of the coverage period are not material. Income earned from financing sales of appliances and other products is recorded within interest income. Any performance obligations arising from returns, refunds or warranties are not material.

Non-operating revenues also arise from sources unrelated to contracts with customers, such as carrying costs recorded on certain regulatory assets, gains from property sales and income from rentals and from equity method investments, among others. In 2018, such amounts include gains realized upon the settlement of certain interest rate swaps (see Note 12). Such revenues are outside the scope of revenues from contracts with customers.

Non-operating revenues are further disclosed in Note 12. Such revenues arising from contracts with customers were not material for any period presented, and accordingly, detailed revenue disclosures are not provided.

Significant Judgments and Estimates

Electricity and natural gas are sold and delivered to the customer for immediate consumption and the customer controls the use of, and obtains substantially all of the benefits from, the energy and related services as they are delivered. As such, the related performance obligations are satisfied over time and revenue is recognized over the same period. The Company and Consolidated SCE&G have determined that their right to consideration from a customer directly corresponds to the value of the performance completed at the date each customer invoice is rendered. As a result, the Company and Consolidated SCE&G recognize revenue in the amounts for which they have a right to invoice. This includes estimated amounts unbilled at a balance sheet date but which are to be invoiced in the normal cycle.

Regulatory mechanisms exist within electric and gas tariffs or orders from regulators that result in adjustments to customer bills. These regulatory mechanisms are designed:

• To recover costs related to fuel, pension, pipeline integrity and energy conservation, among others;

• To recover carrying costs associated with debt-based financing;

• To replace revenues lost as a result of the utility implementing DER programs and DSM Programs; and,

• For gas revenues, to achieve weather normalization or to decouple gas revenues from weather and other factors, such as through the WNA at SCE&G or the CUT at PSNC Energy.

Recovery of deferred costs and carrying costs and the replacement of lost revenues are components of approved tariffs, and therefore, adjustments to customer bills occur as electricity or natural gas is sold and delivered to the customer. As such, the Company and Consolidated SCE&G have concluded that performance obligations related to these adjustments are not capable of being distinct from the underlying tariff based sales. Accordingly, revenues arising from these adjustments are

25

recorded within Operating Revenues - Electric or Gas regulated on the statements of operations, consistent with revenues from underlying tariff based sales.

Adjustments for SCE&G’s WNA increase customer bills when weather is milder than normal and decrease customer bills when weather is colder than normal. These adjustments are made during the same period that the underlying natural gas is sold and delivered to the customer, and the performance obligations associated with these adjustments are not capable of being distinct from tariff based sales. Such adjustments are recorded within Operating Revenues - Gas regulated on the statements of operations. When weather is significantly milder than normal, SCE&G limits such adjustments on a customer’s bill to an amount that would be added if weather were 50% milder than normal. Adjustments exceeding this limit, though still recorded as operating revenue, are deferred within regulatory assets until customers are subsequently billed for the excess with the approval of the SCPSC.

PSNC Energy’s CUT is a decoupling mechanism that adjusts bills for residential and commercial customers based on per customer average consumption. When average consumption exceeds actual usage, PSNC Energy records increased revenue associated with this undercollection and defers it within regulatory assets. Likewise, when actual usage exceeds average consumption, a decrement to revenue associated with this overcollection is recorded and deferred within regulatory liabilities. PSNC Energy’s tariff based rates are adjusted semiannually, with the approval of the NCUC, to collect or refund these deferred amounts over the subsequent 12 month period.

Amounts deferred for the WNA and the CUT arise under specific arrangements with regulators rather than customers. As a result, the Company and Consolidated SCE&G have concluded that these arrangements represent alternative revenue programs. Revenue from alternative revenue programs is included within Operating Revenues - Gas-regulated on the statements of operations in the month such adjustments are deferred within regulatory accounts, and is shown as Other revenues when disaggregated in the table below. As permitted, the Company and Consolidated SCE&G have elected to reduce the regulatory accounts in the period when such amounts are reflected on customer bills without affecting operating revenues.

Disaggregation of Revenues

The impact of several factors on the amount, timing and uncertainty of operating revenues and cash flows can vary significantly by customer class. For electric revenues and nonregulated gas revenues, which do not have weather normalization mechanisms in place, the impact of weather and conservation measures on energy usage typically affect residential and commercial customers to a greater degree than other customer classes. For utilities, revenue requirements result in increases or decreases in tariff rates approved by regulatory bodies and often vary by customer class. Also, certain cost recovery and other mechanisms may have an uneven impact on a particular customer class depending on the underlying tariffs affected. For nonregulated gas, revenues are impacted by competitive market rates tailored to appeal to specific customer classes. The Company and Consolidated SCE&G have disaggregated operating revenues by customer class as follows:

The Company	Consolidated SCE&G				PSNC Energy			Total Gas-regulated		Gas-nonregulated
Segments (Millions of dollars)	Electric		Gas-regulated		Gas-regulated
Three months ended March 31, 2018
Customer class:
Residential	$	252	$	86	$	145		$	231	$	106

Other operating revenues	3		1		(1		)	—		—
Total Operating Revenues	$	546	$	155	$	206		$	361	$	273

Contract Costs

Costs to obtain contracts are generally expensed when incurred. In limited instances, SCE&G provides economic development grants intended to support economic growth within SCE&G’s electric service territory and defers such grants as regulatory assets on the condensed consolidated balance sheet. Whenever these grants are contingent on a customer entering

26

into a long-term electric supply contract with SCE&G, they are considered costs to obtain that underlying contract. Such costs are amortized on a straight-line basis over the term of the related service contract, which generally ranges from ten to 15 years.

Balances and activity related to contract costs deferred as regulatory assets were as follows:

The Company and Consolidated SCE&G
Millions of dollars	Regulatory Assets
January 1, 2018	$	16.3
Additional costs	—
Amortization	(0.4		)
Impairment	—
March 31, 2018	$	15.9

4.    COMMON EQUITY

SCANA had 200 million shares of common stock authorized as of March 31, 2018 and December 31, 2017.

Authorized shares of SCE&G common stock were 50 million as of March 31, 2018 and December 31, 2017. Authorized shares of SCE&G preferred stock were 20 million, of which 1,000 shares, no par value, were issued and outstanding as of March 31, 2018 and December 31, 2017. All issued and outstanding shares of SCE&G's common and preferred stock are held by SCANA.

SCANA’s articles of incorporation do not limit the dividends that may be paid on its common stock, and the articles of incorporation of each of SCANA's subsidiaries contain no such limitations on their respective common stock. SCANA has agreed to obtain the consent of Dominion Energy, which consent cannot be unreasonably withheld, prior to making dividend payments to shareholders greater than $0.6125 per share for any quarter while the Merger Agreement is pending.

SCE&G’s bond indenture under which it issues First Mortgage Bonds contains provisions that could limit the payment of cash dividends on its common stock. SCE&G's bond indenture permits the payment of dividends on SCE&G's common stock only either (1) out of its Surplus (which is defined as the excess of net assets over capital) or (2) in case there is no Surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. In addition, the Federal Power Act requires the appropriation of a portion of certain earnings from hydroelectric projects. At March 31, 2018 and 2017, retained earnings of approximately $95.3 million and $80.6 million, respectively, were restricted by this requirement as to payment of cash dividends on SCE&G’s common stock.

PSNC Energy’s note purchase and debenture purchase agreements contain provisions that could limit the payment of cash distributions, including dividends, on PSNC Energy's common stock. These agreements generally limit the sum of distributions to an amount that does not exceed $30 million plus 85% of Consolidated Net Income (as therein defined) accumulated after December 31, 2008 plus the net proceeds of issuances by PSNC Energy of equity or convertible debt securities (as therein defined). As of March 31, 2018, this limitation would permit PSNC Energy to pay cash distributions in excess of $100 million.

5.     LONG-TERM DEBT AND LIQUIDITY

Long-term Debt

Substantially all electric utility plant is pledged as collateral in connection with long-term debt.

Liquidity

Credit agreements are used for general corporate purposes, including liquidity support for each company's commercial paper program and working capital needs and, in the case of Fuel Company, to finance or refinance the purchase of nuclear fuel, certain fossil fuels, and emission and other environmental allowances. Committed long-term facilities are revolving lines of credit under credit agreements with a syndicate of banks. Committed LOC, outstanding LOC advances, commercial paper, and LOC-supported letter of credit obligations were as follows:

In March 2018, SCE&G borrowed $100 million under the five-year credit agreement expiring December 2020. The interest rate on this draw at March 31, 2018 was 2.97%, and this draw is classified as long term debt. Proceeds from the draw were deposited with a natural gas supplier to provide contractually required credit support. The interest rate on this deposit currently exceeds the interest rate on the draw. Also, in February 2018 SCANA issued a $43.4 million letter of credit in favor of a natural gas supplier to provide contractually required credit support.

Portions of the proceeds received under or arising from the monetization of the Toshiba Settlement in late September and early October 2017 have been utilized to repay maturing commercial paper balances, which short-term borrowings had been incurred for the construction of Unit 2 and Unit 3 prior to the decision to stop their construction (see Note 10). Should the SCPSC or a court direct that these proceeds be refunded to customers in the near-term, or direct that such funds be escrowed or otherwise made unavailable to SCE&G, it is anticipated that SCE&G would issue commercial paper, draw on its credit facilities or issue long-term debt to fund such requirement. However, were the SCPSC to rule in favor of the ORS in response to the Request that SCE&G suspend collections from customers of amounts previously authorized under the BLRA, or were other actions of the SCPSC or others taken in order to significantly restrict SCE&G’s access to revenues or impose additional adverse refund obligations on SCE&G, the Company’s and Consolidated SCE&G's assessments regarding the recoverability of all or a portion of the remaining balance of unrecovered nuclear project costs would be adversely impacted (see Note 2). Further, the recognition of significant additional impairment losses with respect to unrecovered Nuclear Project costs could increase the Company’s and Consolidated SCE&G’s debt to total capitalization to a level which may limit their ability to borrow under their commercial paper programs or under their credit facilities. Borrowing costs for long-term debt issuances could also be impacted.

Each of the Company and Consolidated SCE&G is obligated with respect to an aggregate of $67.8 million of industrial revenue bonds which are secured by letters of credit issued by TD Bank N.A. These letters of credit expire, subject to renewal, in the fourth quarter of 2019.

    Consolidated SCE&G participates in a utility money pool with SCANA and another regulated subsidiary of SCANA. Money pool borrowings and investments bear interest at short-term market rates. Consolidated SCE&G’s interest income and expense from money pool transactions were not significant for any period presented. Consolidated SCE&G had outstanding money pool borrowings due to an affiliate of $197 million and investments due from an affiliate of $149 million at March 31,

28

2018. At December 31, 2017 Consolidated SCE&G had outstanding money pool borrowings due to an affiliate of $37 million and investments due from an affiliate of $28 million. For each period presented, money poo1 borrowings were made by Fuel Company and GENCO, and money pool investments were made by SCE&G. On its condensed consolidated balance sheet, Consolidated SCE&G includes money pool borrowings within Affiliated payables and money pool investments within Affiliated companies receivables.

6.    INCOME TAXES

The Company files consolidated federal income tax returns which include Consolidated SCE&G, and the Company and its subsidiaries file various applicable state and local income tax returns.

The Company’s federal returns through 2007 are closed. In addition, federal returns for 2008 and 2009 are closed except to the extent of the examination of amended return claims discussed below. The IRS is also currently examining SCANA's federal returns for years 2010 through 2016 as a result of those claims. With few exceptions, the Company, including Consolidated SCE&G, is no longer subject to state and local income tax examinations by tax authorities for years before 2010.

During 2013 and 2014, the Company amended certain of its income tax returns for 2008 through 2012 to claim additional tax-defined research and experimentation deductions (under IRC Section 174) and credits (under IRC Section 41) and to reflect related impacts on other items such as domestic production activities deductions (under IRC Section 199). The Company also made similar claims in filing its original 2013 and 2014 returns in 2014 and 2015, respectively. In 2016 and 2017, the Company claimed significant research and experimentation deductions and credits (offset by reductions in its domestic production activities deductions), related to the design and construction activities of the Nuclear Project, in its 2015 and 2016 income tax returns. The Company expects to claim similar deductions and credits in its 2017 tax return when it is filed in 2018. These claims followed the issuance of final IRS regulations in 2014 regarding such treatment with respect to expenditures related to the design and construction of pilot models.

The IRS examined the claims in the amended returns, and as the examination progressed without resolution, the Company and Consolidated SCE&G evaluated and recorded adjustments to unrecognized tax benefits; however, none of these changes materially affected the Company's and Consolidated SCE&G's effective tax rate. In October 2016, the examination of the amended tax returns progressed to the IRS Office of Appeals. In addition, the IRS has begun an examination of SCANA's 2013 through 2016 income tax returns, and it is expected that the IRS will also examine later returns.

These IRC Section 174 income tax deductions and IRC Section 41 credits were considered to be uncertain tax positions, and under relevant accounting guidance, estimates of the amounts of related tax benefits which may not be sustained upon examination by the taxing authorities were recorded as unrecognized tax benefits in the financial statements. Following the abandonment of the Nuclear Project, the Company and Consolidated SCE&G anticipate that an abandonment loss deduction under IRC Section 165 will be claimed on the 2017 tax return. As such, certain of the IRC Section 174 deductions, to the extent they are denied, would instead be deductible in 2017 under IRC Section 165. The abandonment loss deduction is also considered an uncertain tax position; however, under relevant accounting guidance, no estimated unrecognized tax benefits were recorded as of March 31, 2018. The remaining unrecognized tax benefits include the impact of the IRC Section 174 deductions on domestic production activities deductions, credits, and certain unrecognized state tax benefits.

As of March 31, 2018, the Company and Consolidated SCE&G have recorded an unrecognized tax benefit of $98 million ($19 million net of the impact of state deductions on federal returns, net of NOL and credit carryforwards, and net of receivables related to the uncertain tax positions). If recognized, $98 million of the tax benefit would affect the Company’s and Consolidated SCE&G's effective tax rates. These unrecognized tax benefits are not expected to increase significantly within the next 12 months. It is also reasonably possible that these unrecognized tax benefits may decrease by $11 million within the next 12 months. No other material changes in the status of the Company’s or Consolidated SCE&G's tax positions have occurred through March 31, 2018 (see Note 10).

  In connection with the research and experimentation deduction and credit claims reflected on the 2015 and 2016 income tax returns and similar claims made in determining taxable income for 2017, and under the terms of an SCPSC order, the Company and Consolidated SCE&G recorded regulatory assets for estimated foregone domestic production activities deductions, offset by estimated tax credits, with the expectation that these deferred costs and related interest thereon would be recoverable through customer rates in future years (see Note 2). However, an impairment loss with respect to such deferred regulatory asset was recorded in 2017.

29

Also under the terms of an SCPSC order, estimated interest expense accrued with respect to the unrecognized tax benefits related to the research and experimentation deductions in the 2015 and 2016 income tax returns was deferred as a regulatory asset through December 31, 2017 and was expected to be recoverable through customer rates in future years. An impairment loss with respect to these deferred amounts was also recorded as of December 31, 2017 (see Note 10). Otherwise, the Company and Consolidated SCE&G recognize interest accrued related to unrecognized tax benefits within interest expense or interest income and recognize tax penalties within other expenses. Related to the unrecognized tax benefits noted above, the Company and Consolidated SCE&G accrued interest expense of $4.5 million and interest income of $0.7 million during 2018. Amounts recorded for such interest income and interest expense were mostly deferred within regulatory assets during 2017 and were subsequently included within the impairment loss recorded by the Company and Consolidated SCE&G in 2017. Penalties were not material in either period presented.

In December of 2017, the Tax Act was enacted to lower the federal statutory tax rate from 35% to 21%. The rate change resulted in the remeasurement of all federal deferred income tax assets and liabilities to reflect a 21% federal statutory tax rate as of December 31, 2017. Due to the regulated nature of the Company’s and Consolidated SCE&G’s operations, the effect of this remeasurement is primarily reflected in deferred income tax balances within regulatory liabilities. As of March 31, 2018, the amortization of amounts arising from remeasurement have not affected the Company’s or Consolidated SCE&G’s effective tax rate due to such amortizations being deferred until such time as regulators determine how the benefits of such excess deferred tax amounts will be realized by customers. Upon the filing of the Company’s 2017 consolidated income tax return, adjustments to deferred income taxes may be recorded; however, these adjustments are not expected to have a material impact on the Company’s financial position, results of operations, or cash flows.

The State of North Carolina lowered its corporate income tax rate to 3.0% in 2017 and 2.5% effective January 1, 2019. In connection with these changes in tax rates, related state deferred tax amounts were remeasured, with the change in their balances being credited to a regulatory liability. The changes in income tax rates did not and are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

7.    DERIVATIVE FINANCIAL INSTRUMENTS

Derivative instruments are recognized either as assets or liabilities in the statement of financial position and are measured at fair value. Changes in the fair value of derivative instruments are recognized either in earnings, as a component of other comprehensive income (loss) or, for regulated operations, within regulatory assets or regulatory liabilities, depending upon the intended use of the derivative and the resulting designation. 

Policies and procedures, and in some cases risk limits, are established to control the level of market, credit, liquidity and operational and administrative risks.  SCANA’s Board of Directors has delegated to a Risk Management Committee the authority to set risk limits, establish policies and procedures for risk management and measurement, and oversee and review the risk management process and infrastructure for SCANA and each of its subsidiaries.  The Risk Management Committee, which is comprised of certain officers, including the Risk Management Officer and other senior officers, apprises the Audit Committee of the Board of Directors with regard to the management of risk and brings to their attention significant areas of concern. Written policies define the physical and financial transactions that are approved, as well as the authorization requirements and limits for transactions.

Commodity Derivatives

The Company uses derivative instruments to hedge forward purchases and sales of natural gas, which create market risks of different types.  Instruments designated as cash flow hedges are used to hedge risks associated with fixed price obligations in a volatile market and risks associated with price differentials at different delivery locations. Instruments designated as fair value hedges are used to mitigate exposure to fluctuating market prices created by fixed prices of stored natural gas.  The basic types of financial instruments utilized are exchange-traded instruments, such as NYMEX futures contracts or options, and over-the-counter instruments such as options and swaps, which are typically offered by energy companies and financial institutions.  Cash settlements of commodity derivatives are classified as operating activities in the consolidated statements of cash flows.

PSNC Energy hedges natural gas purchasing activities using over-the-counter options and NYMEX futures and options.  PSNC Energy’s tariffs include a provision for the recovery of actual gas costs incurred, including any costs of hedging.  PSNC Energy records premiums, transaction fees, margin requirements and any realized gains or losses from its hedging program in deferred accounts as a regulatory asset or liability for the under- or over-recovery of gas costs.  These derivative financial instruments are not designated as hedges for accounting purposes.

30

Unrealized gains and losses on qualifying cash flow hedges of nonregulated operations are deferred in AOCI.  When the hedged transactions affect earnings, previously recorded gains and losses are reclassified from AOCI to cost of gas.  The effects of gains or losses resulting from these hedging activities are either offset by the recording of the related hedged transactions or are included in gas sales pricing decisions made by the business unit.

As an accommodation to certain customers, SCANA Energy, as part of its energy management services, offers fixed price supply contracts which are accounted for as derivatives.  These sales contracts are offset by the purchase of supply futures and swaps which are also accounted for as derivatives. Neither the sales contracts nor the related supply futures and swaps are designated as hedges for accounting purposes.

Interest Rate Swaps

Interest rate swaps may be used to manage interest rate risk and exposure to changes in fair value attributable to changes in interest rates on certain debt issuances.  In cases in which swaps designated as cash flow hedges are used to synthetically convert variable rate debt to fixed rate debt, periodic payments to or receipts from swap counterparties related to these derivatives are recorded within interest expense.

Forward starting swap agreements that are designated as cash flow hedges may be used in anticipation of the issuance of debt.  Except as described in the following paragraph, the effective portions of changes in fair value and payments made or received upon termination of such agreements for regulated subsidiaries are recorded in regulatory assets or regulatory liabilities. For SCANA and its nonregulated subsidiaries, such amounts are recorded in AOCI. Such amounts are amortized to interest expense over the term of the underlying debt. Ineffective portions of fair value changes are recognized in income.

Pursuant to regulatory orders, interest rate derivatives entered into by SCE&G after October 2013 are not designated for accounting purposes as cash flow hedges, and fair value changes and settlement amounts related to them have been recorded as regulatory assets and liabilities. Settlement losses on swaps have generally been amortized over the lives of subsequent debt issuances and gains have been amortized to interest expense or may be applied as otherwise directed by the SCPSC. See Note 2 and Note 12 regarding the settlement gain recorded in the first quarter of 2018.

Cash payments made or received upon termination of these financial instruments are classified as investing activities for cash flow statement purposes.

Derivatives Designated as Fair Value Hedges

The Company had no interest rate or commodity derivatives designated as fair value hedges for either period presented.

The effect of derivative instruments on the consolidated statements of income is as follows: 

Derivatives in Cash Flow Hedging Relationships

The Company and Consolidated SCE&G:
	Gain Deferred in Regulatory Accounts				Loss Reclassified from Deferred Accounts into Income
Millions of dollars	2018		2017	Location	2018	2017
Three Months Ended March 31,
Interest rate contracts	$	2	—	Interest expense	—	$	(1	)

The Company:
	Gain (Loss) Recognized in OCI, net of tax						Gain (Loss) Reclassified from AOCI into Income, net of tax
Millions of dollars	2018		2017			Location	2018			2017
Three Months Ended March 31,
Interest rate contracts	$	2	—			Interest expense	$	(2	)	$	(2	)
Commodity contracts	1		$	(2	)	Gas purchased for resale	(2		)	2
Total	$	3	$	(2	)		$	(4	)	—

As of March 31, 2018, the Company expects that during the next 12 months reclassifications from AOCI to earnings arising from cash flow hedges will include approximately $0.6 million as an increase to gas cost, assuming natural gas markets remain at their current levels, and approximately $7.8 million as an increase to interest expense.  As of March 31, 2018, all of the Company’s commodity cash flow hedges settle by their terms before the end of 2020.

As of March 31, 2018, each of the Company and Consolidated SCE&G expects that during the next 12 months reclassifications from regulatory accounts to earnings arising from cash flow hedges designated as hedging instruments will include approximately $1.2 million as an increase to interest expense.

Hedge Ineffectiveness

For the Company and Consolidated SCE&G, ineffectiveness on interest rate hedges designated as cash flow hedges was insignificant during all periods presented.

Derivatives Not designated as Hedging Instruments
The Company and Consolidated SCE&G:
	Gain Deferred in Regulatory Accounts					Gain (Loss) Reclassified from Deferred Accounts into Income
Millions of dollars	2018		2017		Location	2018		2017
Three Months Ended March 31,
Interest rate contracts	$	65	$	11	Interest Expense	—		$	(1	)
					Other Income	$	115	—

As of March 31, 2018, each of the Company and Consolidated SCE&G expects that during the next 12 months reclassifications from regulatory accounts to earnings arising from derivatives not designated as hedges will include $2.7 million as an increase to interest expense.

Credit Risk Considerations

Certain derivative contracts contain contingent credit features. These features may include (i) material adverse change clauses or payment acceleration clauses that could result in immediate payments or (ii) the posting of letters of credit or termination of the derivative contract before maturity if specific events occur, such as a credit rating downgrade below investment grade or failure to post collateral.

Derivative Contracts with Credit Contingent Features
	The Company					Consolidated SCE&G
Millions of dollars	March 31, 2018			December 31, 2017		March 31, 2018			December 31, 2017

Aggregate fair value of derivatives in net liability position	$	26.2		$	33.7	$	10.8		$	14.7
Fair value of collateral already posted	27.1			28.9		10.9			10.1

Additional cash collateral or letters of credit in the event credit-risk-related contingent features were triggered	—			$	53.5	—			$	53.5

In addition, for fixed price supply contracts offered to certain of SCANA Energy's customers, the Company could have called on letters of credit in the amount of $0.9 million related to $3.2 million in commodity derivatives that are in a net asset position at March 31, 2018, compared to letters of credit in the amount of $1.2 million related to derivatives of $4.0 million at December 31, 2017, if all the contingent features underlying these instruments had been fully triggered.

8.    FAIR VALUE MEASUREMENTS, INCLUDING DERIVATIVES

The Company and Consolidated SCE&G value available for sale securities using quoted prices from a national stock exchange, such as the NASDAQ, on which the securities are actively traded or are open-ended mutual funds registered with the SEC and maintain a stable NAV and are invested in government money market agreements or fully collateralized repurchase agreements. For commodity derivative and energy management assets and liabilities, the Company uses unadjusted NYMEX prices to determine fair value, and considers such measures of fair value to be Level 1 for exchange traded instruments and Level 2 for over-the-counter instruments. The Company’s and Consolidated SCE&G's interest rate swap agreements are valued using discounted cash flow models with independently sourced data. Fair value measurements, and the level within the fair value hierarchyin which the measurements fall, were as follows:

36

	As of March 31, 2018						As of December 31, 2017
	The Company				Consolidated SCE&G		The Company				Consolidated SCE&G
Millions of dollars	Level 1		Level 2		Level 2		Level 1		Level 2		Level 1		Level 2

Commodity contracts	1		—		—		2		1		—		—
Energy management contracts	1		4		—		1		4		—		—

The Company and Consolidated SCE&G had no Level 3 fair value measurements for either period presented, and there were no transfers of fair value amounts into or out of Levels 1, 2 or 3 during either period presented.

Financial instruments for which the carrying amount may not equal estimated fair value were as follows:

Long-Term Debt	March 31, 2018				December 31, 2017
Millions of dollars	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
The Company	$	6,728.9	$	7,220.1	$	6,632.9	$	7,399.7
Consolidated SCE&G	5,259.0		5,649.1		5,163.3		5,790.3

Fair values of long-term debt instruments are based on net present value calculations using independently sourced market data that incorporate a developed discount rate using similarly rated long-term debt, along with benchmark interest rates.  As such, the aggregate fair values presented above are considered to be Level 2. Early settlement of long-term debt may not be possible or may not be considered prudent.

Carrying values of short-term borrowings approximate fair value, and are based on quoted prices from dealers in the commercial paper market. The resulting fair value is considered to be Level 2.

In connection with the impairment loss described in Note 10, the Company and Consolidated SCE&G determined that the fair value of certain of their nuclear fuel was lower than its carrying amount. At March 31, 2018, this nuclear fuel had an estimated fair value of $40.2 million. This estimate is based on quoted prices received from vendors of nuclear fuel, which are considered to be Level 3 fair value measurements. The Company and Consolidated SCE&G assess the fair value of nuclear fuel in connection with the analysis of impairment described in Note 10 on a quarterly basis.

9.    EMPLOYEE BENEFIT PLANS

Components of net periodic benefit cost recorded by the Company and Consolidated SCE&G were as follows: 

The Company	Pension Benefits						Other Postretirement Benefits
	2018			2017			2018		2017
Three months ended March 31,
Service cost	$	5.0		$	5.3		$	1.2	$	1.2

37

Consolidated SCE&G	Pension Benefits						Other Postretirement Benefits
	2018			2017			2018		2017
Three months ended March 31,
Service cost	$	4.1		$	4.4		$	1.0	$	1.0

Amortization of actuarial losses	2.5			3.4			0.4		0.3
Net periodic benefit cost	$	1.8		$	4.4		$	3.5	$	3.7

No significant contribution to the pension trust is expected for the foreseeable future based on current market conditions and assumptions, nor is a limitation on benefit payments expected to apply. SCE&G recovers current pension costs through either a rate rider that may be adjusted annually for retail electric operations or through cost of service rates for gas operations. PSNC Energy recovers pension costs through cost of service rates.

10.    COMMITMENTS AND CONTINGENCIES

Abandoned Nuclear Project

SCE&G, on behalf of itself and as agent for Santee Cooper, entered into the EPC Contract with the Consortium in 2008 for the design and construction of Unit 2 and Unit 3. Various difficulties were encountered which affected the ability of the Consortium to adhere to established budgets and construction schedules for the Nuclear Project and which, in light of Santee Cooper's decision to suspend construction of the Nuclear Project, led to the Company's decision on July 31, 2017 to stop the construction and seek recovery under the abandonment provisions of the BLRA. These difficulties and other developments occurring prior to the bankruptcy filing by WEC and WECTEC and other matters are described in Note 10 to the consolidated financial statements included in the Company's and Consolidated SCE&G's combined Form 10-K for the year ended December 31, 2017. Significant developments and continuing contingencies regarding the abandoned Nuclear Project subsequent to December 31, 2017 are disclosed below.

EPC Contract and BLRA Matters

Contractor Bankruptcy Proceedings and Related Uncertainties

On March 29, 2017, WEC and WECTEC, the two members of the Consortium, and certain of their affiliates filed petitions for protection under Chapter 11 of the U.S. Bankruptcy Code, citing a liquidity crisis arising from project contract losses attributable to the Nuclear Project and similar units being built for an unaffiliated company as a material factor that caused WEC and WECTEC to seek protection under the bankruptcy laws. As part of such filing, WEC and WECTEC publicly announced their inability to complete Unit 2 and Unit 3 under the terms of the EPC Contract.

On September 1, 2017, SCE&G, for itself and as agent for Santee Cooper, filed with the Bankruptcy Court Proofs of Claim for unliquidated damages against each of WEC and WECTEC. These Proofs of Claim are based upon the anticipatory repudiation and material breach by the Consortium of the EPC Contract, and assert against WEC and WECTEC any and all claims that are based thereon or that may be related thereto. These claims were sold to Citibank on September 27, 2017 as part of a monetization transaction discussed below. Notwithstanding the sale of the claims, SCE&G and Santee Cooper remain responsible for any claims that may be made by WEC and WECTEC against them relating to the EPC Contract.

WEC’s Reorganization Plan was confirmed by the Bankruptcy Court on March 28, 2018. WEC has projected that its Reorganization Plan will pay in full or nearly in full its pre-petition trade creditors, including several of the WEC Subcontractors which have alleged non-payment by the Consortium for amounts owed for work performed on the Nuclear Project and have filed liens on property in Fairfield County, South Carolina, where Unit 2 and Unit 3 were to be located (Unit 2/3 Property). SCE&G is contesting approximately $290 million of filed liens in Fairfield County. Most of these asserted liens are “pre-petition” claims that relate to work performed by WEC Subcontractors before the WEC bankruptcy, although some of them are “post-petition” claims arising from work performed after the WEC bankruptcy.

WEC has indicated that Fluor may attempt to include an approximately$270 million claim (Fluor Claim) for contractual termination damages arising from a breach of Fluor’s subcontract with WEC, in a class of general unsecured

38

creditors that includes the pre-petition trade creditors. However, amounts approved in the Reorganization Plan to pay general unsecured creditors did not contemplate the Fluor Claim. As such, if Fluor is successful in its attempt to include the Fluor Claim as part of the class of general unsecured creditors, it is possible that the Reorganization Plan will not provide for payment in full or nearly in full its pre-petition trade creditors. See also discussion below regarding limitations with respect to SCE&G’s pre-petition lien obligations arising from its monetization of the Toshiba Settlement.

SCE&G and Santee Cooper are responsible for amounts owed to WEC for work performed by WEC Subcontractors on the Nuclear Project after the WEC bankruptcy filing, to the extent such owed amounts exceeded (1) the amounts advanced to WEC for such purposes while the IAA was in effect or (2) the amounts held by WEC after the IAA was terminated. Sufficient funds were not advanced to WEC under the IAA to pay the Fluor claim. If the Fluor Claim is asserted against SCE&G, whether directly or indirectly by a claim through the IAA, SCE&G intends to oppose that claim. To the extent any of these claims are determined to be valid, SCE&G may be responsible for paying its 55% share thereof.

Toshiba Settlement and Subsequent Monetization

Payment and performance obligations under the EPC Contract are joint and several obligations of WEC and WECTEC. In 2015 Toshiba, WEC’s parent company, reaffirmed its guaranty of WEC’s payment obligations. In satisfaction of such guaranty obligations, on July 27, 2017, the Toshiba Settlement was executed under which Toshiba was to make periodic settlement payments beginning in October 2017 in the total amount of approximately $2.2 billion ($1.2 billion for SCE&G’s 55% share), subject to certain offsets for payments by WEC in bankruptcy that would have the effect of satisfying the liens discussed below.

In September and October 2017, proceeds totaling approximately $1.997 billion were received in full satisfaction of the Toshiba Settlement ($1.094 billion for SCE&G's 55% share, net of certain expenses). The proceeds were obtained through the receipt of a payment from Toshiba and a payment from Citibank arising from its purchase of all other scheduled payments, including amounts related to the contractor liens discussed below. The purchase agreement with Citibank provides that SCE&G and Santee Cooper (each according to its pro rata share) would indemnify Citibank for its losses arising from misrepresentations or covenant defaults under the purchase agreement. SCE&G and Santee Cooper also assigned their claims under the WEC bankruptcy process to Citibank, and agreed to use commercially reasonable efforts to cooperate with Citibank and provide reasonable support necessary for its enforcement of those claims. The proceeds received under or arising from the monetization of the Toshiba Settlement were recorded as a regulatory liability on the accompanying consolidated balance sheets, as the net value of the proceeds will be utilized to benefit SCE&G's customers in a manner to be determined by the SCPSC. While this determination is pending, SCE&G has utilized the proceeds to repay maturing commercial paper balances, which short-term borrowings had been incurred primarily for the construction of Unit 2 and Unit 3 prior to the decision to stop their construction. See further discussion in Note 5.

As described above, several WEC Subcontractors have filed liens against the Unit 2/3 Property, which SCE&G is contesting. Payments under the Toshiba Settlement are subject to reduction if WEC pays WEC Subcontractors holding pre-petition liens directly. Under these circumstances, SCE&G and Santee Cooper, each in its pro rata share, would be required to make Citibank whole for the reduction. On January 2, 2018, the purchase agreement with Citibank was amended to limit the amount that SCE&G and Santee Cooper could be required to reimburse Citibank for valid subcontractor and vendor pre-petition liens to $60 million ($33 million for SCE&G's 55% share).

Regulatory, Political and Legal Developments

In September 2017, the Company was served with a subpoena issued by the United States Attorney’s Office for the District of South Carolina seeking documents relating to the Nuclear Project. The subpoena requires the Company to produce a broad range of documents related to the project. Also in September 2017, the state's Office of Attorney General, the Speaker of the House of Representatives, and the Chair and Vice-Chair of the South Carolina House Utility Ratepayer Protection Committee requested that SLED conduct a criminal investigation into the handling of the Nuclear Project by SCANA and SCE&G. In October 2017, the staff of the SEC's Division of Enforcement also issued a subpoena for documents related to an investigation they are conducting related to the Nuclear Project. The investigations have continued since those events. The Company and Consolidated SCE&G intend to fully cooperate with these investigations. Also in connection with the abandonment of the Nuclear Project, various state or local governmental authorities have attempted and may further attempt to challenge, reverse or revoke previously-approved tax or economic development incentives, benefits or exemptions and may attempt to apply such action retroactively. No assurance can be given as to the timing or outcome of these matters. See Claims and Litigation for a description of specific challenges.

39

On September 26, 2017, the South Carolina Office of Attorney General issued an opinion stating, among other things, that "as applied, portions of the BLRA are constitutionally suspect," including the abandonment provisions. Also on September 26, 2017, and in reliance on the opinion from the Office of Attorney General, the ORS filed the Request seeking an order from the SCPSC directing SCE&G to immediately suspend all revised rates collections from customers which were previously approved by the SCPSC pursuant to the authority of the BLRA. In the Request, the ORS noted the existence of an allegation that SCE&G failed to disclose information to the ORS that should have been disclosed and that would have appeared to provide a basis for challenging prior requests, and asserted that SCE&G should not be allowed to continue to benefit from nondisclosure. The ORS also asked for an order that, if the BLRA is found to be unconstitutional or the South Carolina General Assembly amends or revokes the BLRA, then SCE&G should make credits to future bills or refunds to customers for prior revised rates collections. SCE&G estimates that revised rates collections, including collections related to transmission assets which have been or are expected to be placed into service, currently total approximately $445 million annually, and such amounts accumulated as of March 31, 2018 total approximately $2.0 billion. On October 17, 2017, the ORS filed a motion with the SCPSC to amend the Request, in which motion the ORS asked the SCPSC to consider the most prudent manner by which SCE&G will enable its customers to realize the value of the monetized Toshiba Settlement payments and other payments made by Toshiba towards satisfaction of its obligations to SCE&G.

On September 28, 2017, SCE&G filed a motion to dismiss the Request. After conducting a hearing, the SCPSC denied SCE&G's motion on December 20, 2017 and requested that the ORS carry out an inspection, audit and examination of SCE&G's revenue requirements to assist the SCPSC in determining whether SCE&G's present schedule of rates is fair and reasonable. Parties who have intervened and continue to intervene in the Request or who filed a letter in support of the Request include the Governor, the state's Office of Attorney General and Speaker of the House of Representatives, the Electric Cooperatives of South Carolina, Santee Cooper, the SCEUC, certain large industrial customers, and several environmental groups. The hearing on the Request has not been scheduled. SCE&G intends to continue vigorously contesting the Request, but cannot give any assurance as to the timing or outcome of this matter. See also Note 2.

In 2017, special committees of the South Carolina General Assembly, both in the House of Representatives and in the Senate, conducted public hearings regarding the Company's decision to abandon the Nuclear Project. Several legislative proposals adverse to the Company and Consolidated SCE&G resulted from the work of these committees and certain adverse proposals have been or are being considered by the General Assembly in 2018. In January 2018, these committees also reconvened for the purpose of considering the effects of the proposed merger discussed below on Nuclear Project stakeholders. More recent actions by the General Assembly are discussed below.

On January 31, 2018, the South Carolina House of Representatives passed a bill (H. 4375) that would create an experimental rate by effectively suspending collections from rates previously approved by the SCPSC under the BLRA. This experimental rate would remain in effect during the pendency of administrative proceedings currently before the SCPSC or any appeal therefrom. On April 18, 2018, the South Carolina Senate passed a joint resolution (S. 954) which would, among other things, (1) create a temporary experimental rate that reduces SCE&G electric rates related to nuclear construction costs from 18% to 5%, which reduction would remain in effect from April 1, 2018 until the SCPSC issues a final order on the merits of a docket currently before the SCPSC made pursuant to the BLRA (which docket (i.e., Joint Petition) is discussed below); (2) require the SCPSC to conduct a hearing within 30 days of the experimental rate being ordered to determine if an adjustment to the rate is necessary to ensure SCANA does not become insolvent prior to the SCPSC issuing a final order on the merits of such docket; (3) prohibit the SCPSC from holding a hearing on the merits for such docket (other than administrative or procedural hearings), or making any final determination on any related requests, before November 1, 2018; and (4) require the SCPSC to issue a final order for such docket no later than December 21, 2018. Also, S. 954 would require the SCPSC to order each investor-owned utility to provide an accounting of its estimated tax savings arising from the enactment of the Tax Act for calendar year 2018 and to provide that customers of such utility receive the benefit of these estimated savings, subject to an adjustment in 2019 for the actual savings and benefits realized. On April 25, 2018, the House voted to "non-concur" on S. 954. As a result, differences between legislation approved by the House and Senate will be the subject of conference committee proceedings.

Any bill or joint resolution, including any legislation resulting from a conference committee proceeding, must be approved by both legislative chambers and be signed by, or allowed to become law without the signature of, the Governor before it would be enacted. Neither the Company nor Consolidated SCE&G can predict if or when either of these pieces of legislation will become law, or what additional actions, if any, may be proposed or taken, including other legislative actions related to the BLRA.

Proposals to Resolve Outstanding Issues

On November 16, 2017, SCE&G announced for public consideration a proposal to resolve outstanding issues relating to the Nuclear Project. Under the proposal, SCE&G electric customers were to receive a 3.5% electric rate reduction, the addition of an existing 540-MW natural gas fired power plant by SCE&G with the acquisition cost borne by SCANA shareholders, and the addition of approximately 100-MW of large scale solar energy by SCE&G. The proposal also provided for the recovery of the nuclear construction costs (net of the proceeds of the Toshiba Settlement not utilized for liquidation of project liens) over 50 years. While SCE&G’s proposal was not formally submitted for regulatory approval, discussions with key stakeholders over the ensuing weeks indicated that SCE&G's proposal would not be sufficient to resolve the outstanding issues.

On January 2, 2018, SCANA entered into the Merger Agreement with Dominion Energy, and on January 12, 2018, SCE&G and Dominion Energy filed the Joint Petition requesting SCPSC approval of the merger or a finding that either the merger is in the public interest or that there is an absence of harm arising from the merger. In this petition, the parties commit to providing an up-front, one time rate credit to SCE&G's electric customers totaling approximately $1.3 billion within 90 days of the merger's closing, providing at least a 5% reduction in customer bills, shortening the amortization period for costs related to the Nuclear Project to 20 years, forgoing recovery of approximately $1.7 billion in costs related to the Nuclear Project, and to SCE&G's purchasing an existing 540-MW natural gas fired power plant with no initial investment borne by customers. No assurance can be given as to the timing or outcome of efforts to consummate the Merger Agreement or to obtain approval of the Joint Petition.

Impairment Considerations

Under the current regulatory construct in South Carolina, pursuant to the BLRA or through other means, the ability of SCE&G to recover costs incurred in connection with Unit 2 and Unit 3, and a reasonable return on them, will be subject to review and approval by the SCPSC. In light of the contentious nature of the reviews by legislative committees and others, the adverse impact that would result if proposed legislation is enacted, and the Request being considered by the SCPSC that could result in the suspension of rates currently being collected under the BLRA, as well as the return of such amounts previously collected, there is significant uncertainty as to SCE&G’s ultimate ability to fully recover its costs of Unit 2 and Unit 3 and a return on them from its customers. SCE&G continues to contest the specific challenges described above. However, based on the consideration of those challenges, and particularly in light of SCE&G's proposed solution announced on November 16, 2017 and details in the Joint Petition filed by SCE&G and Dominion Energy with the SCPSC on January 12, 2018, the Company and Consolidated SCE&G have determined that a disallowance of recovery of part of the cost of the abandoned Nuclear Project is both probable and reasonably estimable under applicable accounting guidance. In addition, the Company and Consolidated SCE&G have determined that full recovery of certain other related costs deferred within regulatory assets is less than probable. As a result, in 2017 the Company and Consolidated SCE&G recognized a pre-tax impairment loss totaling $1.118 billion ($690 million net of tax). For the three months ended March 31, 2018, the Company and Consolidated SCE&G have recognized an additional pre-tax impairment loss of approximately $3.6 million ($2.7 million net of tax) in order to further reduce to estimated fair value the carrying value of nuclear fuel which had been acquired for use in Unit 2 and Unit 3.

It is reasonably possible that a change in estimated impairment loss could occur in the near term and could be material; however, all such changes cannot be reasonably estimated. The impairment loss recorded in 2017 reflects impacts similar to those that would have resulted had the proposed solution announced on November 16, 2017 been implemented.. If the merger benefits and cost recovery plan outlined in the Joint Petition are implemented (upon closing of the merger as contemplated in the Merger Agreement), an additional impairment loss and other charges totaling as much as approximately $1.7 billion (approximately $1.3 billion net of tax) would be expected to be recorded. This additional impairment loss would result from the write-off of unrecovered Nuclear Project costs of approximately $846 million recorded within regulatory assets and the recording of additional liabilities for customer refunds totaling approximately $1.875 billion, net of approximately $1.061 billion, which amount represents the monetization of guaranty settlement of $1.094 billion recorded within regulatory liabilities less amounts that may be required to settle contractor liens. If instead the Joint Petition is not approved and the Request by the ORS is approved, if the BLRA is found to be unconstitutional or if the General Assembly amends or revokes the BLRA or approves other legislation with a similar effect, the Company and Consolidated SCE&G may be required to record an additional impairment loss and other charges totaling as much as approximately $4.9 billion (approximately $3.7 billion net of tax). This additional impairment loss would result from the write-off of the remaining unrecovered Nuclear Project costs of $3.966 billion recorded within regulatory assets and the refund of revised rates collections under the BLRA described above of approximately $2.0 billion, net of approximately $1.061 billion, which amount represents the monetization of guaranty settlement of $1.094 billion recorded within regulatory liabilities less amounts that may be required to settle contractor liens. The Company and Consolidated SCE&G do not currently anticipate that any of the $2.0 billion in revenue previously collected will be subject to refund; however, no assurance can be given as to the outcome of this matter.

Liquidity Considerations

              As a result of the decision to stop construction of Unit 2 and Unit 3, downgrades by credit ratings agencies occurred.  The Company and Consolidated SCE&G have significant obligations that must be paid within the next 12 months, including long-term debt maturities and capital lease payments of $727 million for the Company (including $723 million for Consolidated SCE&G), short-term borrowings of $248 million for the Company (including $146 million for Consolidated SCE&G), interest payments of approximately $301 million for the Company (including $256 million for Consolidated SCE&G), and future minimum payments for operating leases of $33 million for the Company (including $26 million for Consolidated SCE&G). Working capital requirements, such as those for fuel supply and similar obligations, also arise due to the lag between when such amounts are paid and when related collection of such costs through customer rates occurs.

              Management believes as of the date of issuance of these financial statements that it has access to available sources of cash to pay obligations when due over the next 12 months. These sources include committed, long-term lines of credit that expire in December 2020 totaling $1.8 billion for the Company (including $1.2 billion for Consolidated SCE&G). In addition, as of the date of issuance of these financial statements, SCE&G continues to collect in customer rates amounts previously approved under the BLRA, as well as amounts provided for in other orders related to non-BLRA electric and gas rates. However, certain of SCANA's credit ratings have fallen below investment grade, which has constrained its ability and that of Fuel Company to issue commercial paper.

Regulatory and legislative proceedings described above, and/or proceedings described under Claims and Litigation below, which are outside of the Company’s and Consolidated SCE&G’s control, may result in the temporary or permanent suspension of all or a portion of the approximately $445 million annually of rates being collected currently under the BLRA, the return of such amounts previously collected of $2.0 billion, or the requirement that SCE&G's share of payments received from the Toshiba Settlement ($1.094 billion) be placed in escrow or be refunded to customers in the near term. Neither the Company nor Consolidated SCE&G can predict if or when these matters may be resolved or what additional actions, if any, may be proposed or taken, including other legislative or regulatory actions related to the BLRA or other litigation.

Were the SCPSC to grant the relief sought by the ORS in the Request or grant similar relief resulting from legislative action, and as further discussed above in Impairment Considerations, an additional impairment loss or other charges totaling as much as approximately $4.9 billion (approximately $3.7 billion net of tax) may be required. Such an impairment loss or other charges would further stress the Company’s and Consolidated SCE&G’s debt to total capitalization ratio and may result in the Company’s and Consolidated SCE&G’s ratio of debt to total capitalization exceeding maximum levels prescribed in their respective credit agreements. Such an event likely would limit the Company’s and Consolidated SCE&G’s ability to borrow under their commercial paper programs and credit facilities and their ability to pay future dividends or may trigger events of default under such agreements.

Known and knowable conditions and events when considered in the aggregate as of the date of issuance of these financial statements do not suggest it is probable that the Company and Consolidated SCE&G will not be able to meet obligations as they come due over the next 12 months. However, possible future actions related to rates or refunds could have a material adverse effect on the Company’s and Consolidated SCE&G’s financial condition, liquidity, results of operations and cash flows such that management’s conclusion with respect to its ability to pay obligations when due could change.

Claims and Litigation

Following the Company’s decision to stop construction of Unit 2 and Unit 3, purported derivative and class action lawsuits have been filed in multiple state circuit courts and federal district court on behalf of customers, shareholders and SCANA (in the case of the derivative shareholder actions), against SCANA, SCE&G, or both, and in certain cases some of their officers and/or directors. The plaintiffs allege various causes of action, including but not limited to waste, breach of fiduciary duty, negligence, unfair trade practices, unjust enrichment, conspiracy, fraud, constructive fraud, misrepresentation and negligent misrepresentation, promissory estoppel, constructive trust, and money had and received, among other causes of action. Plaintiffs generally seek compensatory and consequential damages and statutory treble damages and such further relief as the court deems just and proper. In addition, certain plaintiffs seek a declaration that SCE&G may not charge its customers to reimburse itself for past and continuing costs of the Nuclear Project. Certain plaintiffs also seek to freeze or appoint a receiver for certain of SCE&G’s assets, including all money SCE&G has received under the Toshiba payment guaranty and related settlement agreement and money to be collected from customers for the Nuclear Project.

Purported class action lawsuits have been filed on behalf of investors in federal court against SCANA and certain of its current and former executive officers and directors. The plaintiffs allege, among other things, that defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and RICO. In addition, one plaintiff alleges that

42

director defendants violated Section 14(a) of the Exchange Act and SEC Rule 14a-9 by allowing or causing misleading proxy statements to be issued. The plaintiffs in each of these suits seek compensatory and consequential damages and such further relief as the court deems proper.

Lawsuits seeking class action status have also been filed on behalf of investors in the Court of Common Pleas in the Counties of Lexington and Richland, South Carolina, against SCANA, its CEO and directors, Dominion Energy and Sedona. The plaintiffs allege, among other things, that defendants violated their fiduciary duties to shareholders by executing a merger agreement that unfairly deprived plaintiffs of the true value of their SCANA stock, and that Dominion Energy and Sedona aided and abetted these actions. Among other remedies, the plaintiffs seek to enjoin the merger and rescind the Merger Agreement or to have the Merger Agreement amended to provide more favorable terms for plaintiffs, monetary damages, attorneys' fees and such further relief as the court deems proper.

A complaint has been filed by Fairfield County against SCE&G making allegations of breach of contract, fraud, negligent misrepresentation, breach of fiduciary duty, breach of the implied duty of good faith and fair dealing, and unfair trade practices related to SCE&G’s termination of the FILOT agreement. Plaintiff seeks injunctive relief to prevent SCE&G from terminating the FILOT agreement; actual and consequential damages; treble damages; punitive damages; and attorneys’ fees.

The Company has also been served with subpoenas issued by the United States Attorney’s Office for the District of South Carolina and the staff of the SEC's Division of Enforcement seeking documents relating to the Nuclear Project. In addition, the state's Office of Attorney General, the Speaker of the House of Representatives, and the Chair and Vice-Chair of the South Carolina House Utility Ratepayer Protection Committee have requested that SLED conduct a criminal investigation into the handling of the Nuclear Project by SCANA and SCE&G. The Company and Consolidated SCE&G intend to fully cooperate with any such investigations.

On January 26, 2018, the DOR notified SCANA that it was initiating an audit of SCE&G's sales and use tax returns for the periods September 1, 2008 through December 31, 2017. The Company and Consolidated SCE&G understand that the DOR's position is that the exemption for sales and use tax for purchases related to the Nuclear Project should not apply because Unit 2 and Unit 3 will not be placed into service and no electricity will be manufactured for sale. The Company and Consolidated SCE&G intend to vigorously contest the DOR's position.

While the Company and Consolidated SCE&G intend to vigorously contest the lawsuits, claims, and audit positions which have been filed or initiated against them, they cannot predict the timing or outcome of these matters or others that may arise, including any claims that may be asserted by Santee Cooper, and adverse outcomes from some of these matters would not be covered by insurance. As noted above, the various claims for damages do not specify an amount for those damages and the number of plaintiffs that are ultimately certified in the potential class action lawsuits is unknown. In addition, each of the cases referred to above is in its early stages. For these reasons, the Company and Consolidated SCE&G cannot provide any estimate or range of potential loss for these matters at this time, and no accrual for these potential losses has been included in the condensed consolidated financial statements. However, outcomes could have a material adverse effect on the Company's and Consolidated SCE&G's results of operations, cash flows and financial condition.

The Company and Consolidated SCE&G are subject to various other claims and litigation incidental to their business operations which management anticipates will be resolved without a material impact on the Company's and Consolidated SCE&G's results of operations, cash flows or financial condition.

Nuclear Insurance

Under Price-Anderson, SCE&G (for itself and on behalf of Santee-Cooper) maintains agreements of indemnity with the NRC that, together with private insurance, cover third-party liability arising from any nuclear incident occurring at Unit 1.  Price-Anderson provides funds up to $13.4 billion for public liability claims that could arise from a single nuclear incident.  Each nuclear plant is insured against this liability to a maximum of $450 million by ANI with the remaining coverage provided by a mandatory program of deferred premiums that could be assessed, after a nuclear incident, against all owners of commercial nuclear reactors. Each reactor licensee is liable for up to $127.3 million per reactor owned for each nuclear incident occurring at any reactor in the United States, provided that not more than $18.9 million of the liability per reactor would be assessed per year. SCE&G’s maximum assessment, based on its two-thirds ownership of Unit 1, would be $84.8 million per incident, but not more than $12.6 million per year. Both the maximum assessment per reactor and the maximum yearly assessment are adjusted for inflation at least every five years.

43

SCE&G currently maintains insurance policies (for itself and on behalf of Santee Cooper) with NEIL. The policies provide coverage to Unit 1 for property damage and outage costs up to $2.75 billion resulting from an event of nuclear origin and up to $2.33 billion resulting from an event of a non-nuclear origin. The NEIL policies in aggregate, are subject to a maximum loss of $2.75 billion for any single loss occurrence. The NEIL policies permit retrospective assessments under certain conditions to cover insurer’s losses. Based on the current annual premium, SCE&G’s portion of the retrospective premium assessment would not exceed $22.3 million. SCE&G currently maintains an excess property insurance policy (for itself and on behalf of Santee Cooper) with EMANI. The policy provides coverage to Unit 1 for property damage and outage costs up to $415 million resulting from an event of a non-nuclear origin. The EMANI policy permits retrospective assessments under certain conditions to cover insurer's losses. Based on the current annual premium, SCE&G's portion of the retrospective premium assessment would not exceed $2.0 million.

To the extent that insurable claims for property damage, decontamination, repair and replacement and other costs and expenses arising from an incident at Unit 1 exceed the policy limits of insurance, or to the extent such insurance becomes unavailable in the future, and to the extent that SCE&G's rates would not recover the cost of any purchased replacement power, SCE&G will retain the risk of loss as a self-insurer. SCE&G has no reason to anticipate a serious nuclear or other incident. However, if such an incident were to occur, it likely would have a material impact on the Company’s and Consolidated SCE&G's results of operations, cash flows and financial position.

Environmental

On August 3, 2015, the EPA issued a revised standard for new power plants by re-proposing NSPS under the CAA for emissions of CO₂ from newly constructed fossil fuel-fired units. The final rule required all new coal-fired power plants to meet a carbon emission rate of 1,400 pounds CO₂ per MWh and new natural gas units to meet 1,000 pounds CO₂ per MWh. While most new natural gas plants will not be required to include any new technologies, no new coal-fired plants could be constructed without partial carbon capture and sequestration capabilities. The Company and Consolidated SCE&G are monitoring the final rule, but do not plan to construct new coal-fired units in the foreseeable future.     

On August 3, 2015, the EPA issued its final rule on emission guidelines for states to follow in developing plans to address GHG emissions from existing units. The rule included state-specific goals for reducing national CO₂ emissions by 32% from 2005 levels by 2030, and established a phased-in compliance approach beginning in 2022. The rule gave each state from one to three years to issue its SIP, which would ultimately define the specific compliance methodology that would be applied to existing units in that state. On February 9, 2016, the Supreme Court stayed the rule pending disposition of a petition of review of the rule in the Court of Appeals. As a result of an Executive Order on March 28, 2017, the EPA placed the rule under review and the Court of Appeals agreed to hold the case in abeyance. On October 10, 2017, the Administrator of the EPA signed a notice proposing to repeal the rule on the grounds that it exceeded the EPA's statutory authority. In a separate but related action, the EPA issued an Advance Notice of Proposed Rulemaking on December 18, 2017, to solicit information from the public about a potential future rulemaking to limit greenhouse gas emissions from existing units. The Company and Consolidated SCE&G expect any costs incurred to comply with such rule to be recoverable through rates.

In July 2011, the EPA issued the CSAPR to reduce emissions of SO₂ and NO_X from power plants in the eastern half of the United States. The CSAPR replaces the CAIR and requires a total of 28 states to reduce annual SO₂ emissions and annual and ozone season NO_X emissions to assist in attaining the ozone and fine particle NAAQS. The rule establishes an emissions cap for SO₂ and NO_X and limits the trading for emission allowances by separating affected states into two groups with no trading between the groups. The State of South Carolina has chosen to remain in the CSAPR program, even though recent court rulings exempted the state. This allows the state to remain compliant with regional haze standards. Air quality control installations that SCE&G and GENCO have already completed have positioned them to comply with the existing allowances set by the CSAPR. Any costs incurred to comply with CSAPR are expected to be recoverable through rates.

In April 2012, the EPA's MATS rule containing new standards for mercury and other specified air pollutants became effective. The MATS rule has been the subject of ongoing litigation even while it remains in effect. Rulings on this litigation are not expected to have an impact on SCE&G or GENCO due to plant retirements, conversions, and enhancements. SCE&G and GENCO are in compliance with the MATS rule and expect to remain in compliance.

The CWA provides for the imposition of effluent limitations that require treatment for wastewater discharges. Under the CWA, compliance with applicable limitations is achieved under state-issued NPDES permits such that, as a facility’s NPDES permit is renewed, any new effluent limitations would be incorporated. The ELG Rule had become effective on January 4, 2016, after which state regulators could modify facility NPDES permits to match more restrictive standards, which would require facilities to retrofit with new wastewater treatment technologies. Compliance dates varied by type of wastewater, and some were based on a facility's five-year permit cycle and thus could range from 2018 to 2023. However, the ELG Rule is

44

under reconsideration by the EPA and has been stayed administratively. The EPA has decided to conduct a new rulemaking that could result in revisions to certain flue gas desulfurization wastewater and bottom ash transport water requirements in the ELG Rule. Accordingly, in September 2017 the EPA finalized a rule that resets compliance dates under the ELG Rule to a range from November 1, 2020 to December 31, 2023. The EPA indicates that the new rulemaking process may take up to three years to complete, such that any revisions to the ELG Rule likely would not be final until the summer of 2020. While the Company and Consolidated SCE&G expect that wastewater treatment technology retrofits will be required at Williams and Wateree Stations, any costs incurred to comply with the ELG Rule are expected to be recoverable through rates.

The CWA Section 316(b) Existing Facilities Rule became effective in October 2014. This rule establishes national requirements for the location, design, construction and capacity of cooling water intake structures at existing facilities that reflect the best technology available for minimizing the adverse environmental impacts of impingement and entrainment. SCE&G and GENCO are conducting studies and implementing plans as required by the rule to determine appropriate intake structure modifications to ensure compliance with this rule. Any costs incurred to comply with this rule are expected to be recoverable through rates.

The EPA's final rule for CCR became effective in the fourth quarter of 2015. This rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act and imposes certain requirements on ash storage ponds and other CCR management facilities at SCE&G's and GENCO's coal-fired generating facilities. SCE&G and GENCO have already closed or have begun the process of closure of all of their ash storage ponds and have previously recognized AROs for such ash storage ponds under existing requirements. The Company and Consolidated SCE&G do not expect the incremental compliance costs associated with this rule to be significant and expect to recover such costs in future rates.

SCE&G is responsible for four decommissioned MGP sites in South Carolina which contain residues of by-product chemicals. These sites are in various stages of investigation, remediation and monitoring under work plans approved by DHEC and the EPA. SCE&G anticipates that major remediation activities at all these sites will continue at least through 2019 and will cost an additional $9.9 million, which is accrued in Other within Deferred Credits and Other Liabilities on the condensed consolidated balance sheet. SCE&G expects to recover any cost arising from the remediation of MGP sites through rates. At March 31, 2018, deferred amounts, net of amounts previously recovered through rates and insurance settlements, totaled $24.3 million and are included in regulatory assets.

Other

The Company and Consolidated SCE&G have recorded an estimated liability for amounts collected in customer rates during the period that arise from the impact of the Tax Act. Such amounts have been recorded subject to refund, and are described in Note 2.

11.    SEGMENT OF BUSINESS INFORMATION

Regulated operations measure profitability using operating income; therefore, net income is not allocated to the Electric Operations and Gas Distribution segments. The Gas Marketing segment measures profitability using net income.

The Company's Gas Distribution segment is comprised of the local distribution operations of SCE&G and PSNC Energy which meet the criteria for aggregation. All Other includes the parent company, a services company and other nonreportable segments that were insignificant for all periods presented.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS

OF OPERATIONS

Pursuant to General Instruction H of Form 10-Q, SCE&G is permitted to omit certain information related to itself and its consolidated affiliates called for by Item 2 of Part I of Form 10-Q, and instead provide a management’s narrative analysis of its consolidated results of operation and other information described therein. Such information is presented hereunder specifically for Consolidated SCE&G, but may be presented alongside information presented for the Company generally. Consolidated SCE&G makes no representation as to information relating solely to SCANA and its subsidiaries (other than Consolidated SCE&G).

RESULTS OF OPERATIONS

FOR THE THREE MONTHS ENDED MARCH 31, 2018

AS COMPARED TO THE CORRESPONDING PERIOD IN 2017

The following discussion should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations appearing in SCANA’s and SCE&G’s Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations of the Company include those of the parent holding company and each of its subsidiaries, including Consolidated SCE&G. Accordingly, discussions regarding the Company's results of operations necessarily include those of Consolidated SCE&G.

Earnings

Earnings were as follows:

The Company	2018		2017
Earnings per share	$	1.18	$	1.19
Consolidated SCE&G
Net income (millions of dollars)	$	127.7	$	112.3

The Company's earnings per share and Consolidated SCE&G's net income reflect the impacts of colder weather in 2018 than in 2017, while the Company's earnings per share also reflect higher legal costs and costs incurred in connection with the Company's announced merger with Dominion Energy in 2018. These and other results are discussed below.

Matters Impacting Future Results

The Company's decision on July 31, 2017 to stop construction of Unit 2 and Unit 3 and to pursue recovery of the cost of the abandoned Nuclear Project has had and could continue to have significant adverse impacts on the Company's and Consolidated SCE&G's future earnings, cash flows and financial position, including those related to the ultimate recovery of regulatory assets and the sustainability of tax positions. The Company continues to believe the decision to abandon the Nuclear Project was prudent and that costs incurred with respect to the Nuclear Project were prudent, has contested specific challenges to this decision, and believes that the issues related to the recovery of the cost of the abandoned Nuclear Project and related to the rates currently being collected under the BLRA for financing costs should be resolved in future proceedings before the SCPSC. However, based on various events following the abandonment, there is significant uncertainty as to SCE&G's ultimate ability to fully recover its costs of Unit 2 and Unit 3 and a return on them from its customers. These events include the contentious nature of ongoing reviews by legislative committees and others, legislative proposals being considered by the General Assembly and promoted by the Governor, and the Request being considered by the SCPSC that could result in the suspension of all or a portion of rates currently being collected under the BLRA, as well as the return of such amounts previously collected.

In 2017, the Company and Consolidated SCE&G determined that a disallowance of recovery of part of the cost of the abandoned Nuclear Project was both probable and reasonably estimable under applicable accounting guidance, and recorded a pre-tax impairment loss with respect to disallowance of unrecovered Nuclear Project costs and other related deferred costs totaling approximately $1.118 billion ($690 million net of tax). In the first quarter of 2018, the Company and Consolidated SCE&G recorded an additional impairment totaling approximately $3.6 million ($2.7 million net of tax) related to the decline in the fair value of nuclear fuel that had been acquired for use in Unit 2 and Unit 3. See additional discussion at Note 10 to the condensed consolidated financial statements.

48

It is reasonably possible that further changes in these estimates will occur in the near term and could be material; however, all such changes cannot be reasonably estimated. The impairment loss recorded in 2017 reflects impacts similar to those that would have resulted had the proposed solution announced on November 16, 2017 been implemented. If the merger benefits and cost recovery plan outlined in the Joint Petition is implemented (upon closing of the merger as contemplated in the Merger Agreement), an additional impairment loss and other charges totaling as much as approximately $1.7 billion (approximately $1.3 billion net of tax) would be expected to be recorded. If instead the Joint Petition is not approved and the Request by the ORS is approved, if the BLRA is found to be unconstitutional or if the General Assembly amends or revokes the BLRA or approves other legislation with a similar effect, the Company and Consolidated SCE&G may be required to record an additional impairment loss and other charges totaling as much as approximately $4.9 billion (approximately $3.7 billion net of tax). This additional impairment loss would result from the write-off of the remaining unrecovered Nuclear Project costs of $3.966 billion recorded within regulatory assets and the refund of revised rates collections under the BLRA described above of approximately $2.0 billion, net of approximately $1.061 billion, which amount represents the monetization of guaranty settlement of $1.094 billion recorded within regulatory liabilities less amounts that may be required to settle contractor liens. The Company and Consolidated SCE&G do not currently anticipate that any of the $2.0 billion in revenue previously collected will be subject to refund; however, no assurance can be given as to the outcome of this matter.

                In December 2017, the Tax Act was enacted, resulting in the remeasurement of all federal deferred income tax assets and liabilities to reflect a 21% federal statutory corporate tax rate. Due to the regulated nature of the Company’s and Consolidated SCE&G’s operations, the effect of this remeasurement is primarily reflected in excess deferred income tax balances within regulatory liabilities. As described in Note 2 to the condensed consolidated financial statements, SCE&G and PSNC Energy have responded to orders from state regulators seeking information regarding the effects the Tax Act would have on their respective operations. The Company and Consolidated SCE&G cannot determine the amount or timing of any refunds to customers that may result. However, in 2018, the Company and SCE&G are recording estimates of revenue that will be subject to refund to customers of its regulated operations. Such amounts result in reductions to revenue and are included as current liabilities within customer deposits and customer prepayments on the condensed consolidated balance sheet. Such reductions in revenue largely correspond to reductions in current period tax expense. Going forward, once state regulators order reductions in customer rates, the lower tax expense resulting from the reduced federal statutory tax rate will result in similar reductions to amounts collected from customers through electric and gas rates, and no significant impact on financial results is expected. See also Note 6 to the condensed consolidated financial statements for additional discussion related to deferred tax assets and liabilities.

These matters impacting future results are further discussed under Impact of Abandonment of Nuclear Project within LIQUIDITY AND CAPITAL RESOURCES, in Note 2 and Note 10 to the condensed consolidated financial statements and in Part II, Item 1A. Risk Factors.

Dividends Declared

On February 22, 2018, SCANA's Board of Directors declared a dividend for the quarter ending March 31, 2018 of $0.6125 per share. This dividend was payable on April 1, 2018 to shareholders of record on March 12, 2018. When a dividend payment date falls on a weekend or holiday, the payment is made the following business day.

SCANA's Board of Directors evaluates the payment of dividends each quarter. A determination regarding the payment of a dividend for the quarter ending June 30, 2018, will be made closer to the record date. Dividends declared would be payable July 1, 2018 to shareholders of record on June 11, 2018.

Electric Operations

Electric Operations for the Company and for Consolidated SCE&G is comprised of the electric operations of SCE&G, GENCO and Fuel Company.  Electric Operations operating income (including transactions with affiliates) was as follows:

	The Company				Consolidated SCE&G
Millions of dollars	2018		2017		2018		2017
Operating revenues	$	547.4	$	578.5	$	547.4	$	578.5
Fuel used in electric generation	159.3		136.4		159.3		136.4
Purchased power	52.1		11.1		52.1		11.1
Other operation and maintenance	125.1		120.9		128.5		124.5
Impairment loss	3.6		—		3.6		—
Depreciation and amortization	75.9		73.0		73.0		70.0
Other taxes	57.3		54.7		56.8		54.1
Operating Income	$	74.1	$	182.4	$	74.1	$	182.4

Electric operations can be significantly impacted by the effects of weather. SCE&G estimates the effects on its electric business of actual temperatures in its service territory as compared to historical averages to develop an estimate of electric revenue and fuel costs attributable to the effects of abnormal weather. Results in both 2018 and 2017 reflect milder than normal weather in the first quarter; however, 2017 was significantly milder than 2018.

• Operating revenues decreased by $113.7 million in 2018 pursuant to a previously received SCPSC order whereby fuel cost recovery is offset with gains realized upon the settlement of certain interest rate derivative contracts, as further described in Other Income (Expense) below. Operating revenues also decreased by $25.6 million due to the recognition of estimated amounts to be refunded to customers as a result of the Tax Act, lower collections under the rate rider for pension costs of $2.3 million and lower residential and commercial average use of $1.9 million. The downward adjustment related to fuel cost recovery had no effect on net income as it was fully offset by the recognition within other income of gains realized upon the settlement of certain derivative interest rate contracts. The lower pension rider collections had no impact on net income as they were fully offset by the recognition, within other operation and maintenance expenses and other expense, of lower pension costs. These revenue decreases were partially offset by the effects of weather of $48.7 million, residential and commercial growth of $6.5 million, industrial growth and higher usage of $2.6 million, higher revenue recognized under the DER program of $2.1 million and higher fuel cost recovery of $48.3 million.

• Fuel used in electric generation and purchased power expenses increased due to higher fuel prices of $48.3 million, higher amortization of DER program costs of $1.6 million, increased sales volumes associated with residential and commercial customer growth of $1.4 million, higher industrial usage of $0.8 million, higher sales volumes associated with the effects of weather of $10.6 million and higher fuel handling expenses of $1.4 million. These increases were partially offset by lower residential and commercial average use of $0.2 million.

• Other operation and maintenance expenses increased due to wind down costs associated with the abandonment of the Nuclear Project of $3.7 million.

• Impairment loss represents the writedown of nuclear fuel acquired for use in Unit 2 and Unit 3 to its estimated fair value.

• Depreciation and amortization increased primarily due to net plant additions.

• Other taxes increased primarily due to higher property taxes associated with net plant additions.

50

Sales volumes (in GWh) related to the electric operations above, by class, were as follows:

Classification	2018	2017
Residential	1,987	1,636
Commercial	1,704	1,635
Industrial	1,489	1,459
Other	131	134
Total Retail Sales	5,311	4,864
Wholesale	242	213
Total Sales	5,553	5,077

Retail and wholesale sales volumes increased primarily due to the effects of weather.

Gas Distribution

Gas Distribution is comprised of the local distribution operations of SCE&G, and for the Company, also includes PSNC Energy.  Gas Distribution operating income (including transactions with affiliates) was as follows:

	The Company				Consolidated SCE&G
Millions of dollars	2018		2017		2018		2017
Operating revenues	$	361.0	$	322.1	$	154.6	$	140.9
Gas purchased for resale	170.6		134.8		75.4		65.9
Other operation and maintenance	42.0		42.4		17.3		17.3
Depreciation and amortization	22.9		20.8		7.5		7.0
Other taxes	12.1		10.9		8.1		7.2
Operating Income	$	113.4	$	113.2	$	46.3	$	43.5

The effect of abnormal weather conditions on gas distribution operating income is mitigated by the WNA at SCE&G and the CUT at PSNC Energy as further described in Revenue Recognition in Note 3 of the condensed consolidated financial statements. The WNA and the CUT do not affect sales volumes.

• Operating revenues increased at SCE&G primarily due to increased base rates under the RSA of $4.6 million, customer growth of $3.8 million, higher average use of $1.2 million and higher gas cost recovery of $6.7 million. These increases were partially offset by a decrease of $3.3 million due to the recognition of estimated amounts to be refunded to customers as a result of the Tax Act. In addition to these factors, operating revenues at the Company increased due to colder weather at PSNC Energy of $53.9 million and customer growth of $5.0 million. These increases were partially offset by a CUT adjustment of $17.8 million, decreased cost of gas recoveries of $14.3 million and $6.7 million due to the recognition of estimated amounts to be refunded to customers as a result of the Tax Act.

• Gas purchased for resale at SCE&G reflects increased sales volumes due to weather of $12.6 million, firm customer growth of $1.8 million and higher average use of $1.1 million. These increases were partially offset by lower gas prices of $5.9 million. In addition to these factors, gas purchased for resale at the Company reflects increased sales volumes due to weather at PSNC of $27.0 million, customer growth of $2.4 million, and the effect of a CUT adjustment that decreased gas purchased for resale by $9.0 million in 2017. These increases were partially offset by decreased gas costs of $14.3 million.

• Depreciation and amortization increased primarily due to net plant additions.

• Other taxes increased primarily due to higher property taxes associated with net plant additions.

51

Sales volumes (in MMBTU) related to gas distribution above by class, including transportation, were as follows:

	The Company		Consolidated SCE&G
Classification (in thousands)	2018	2017	2018	2017
Residential	23,189	16,560	7,035	4,905
Commercial	12,057	9,469	4,418	3,752
Industrial	5,507	5,322	4,650	4,654
Transportation	12,147	10,954	1,502	1,556
Total	52,900	42,305	17,605	14,867

Residential and commercial firm sales volumes for the Company and Consolidated SCE&G increased due to the effects of weather and customer growth. Industrial sales and transportation volumes at the Company increased due to the effects of weather at PSNC Energy. Transportation volumes also increased at the Company due to a significant customer expansion and increased natural gas fired electric generation at PSNC Energy, partially offset at Consolidated SCE&G due to increased curtailments in 2018.

Gas Marketing

Gas Marketing is comprised of the Company's nonregulated marketing operation, SCANA Energy, which operates in the southeast and includes Georgia’s retail natural gas market.  Gas Marketing operating revenues and net income were as follows:

Millions of dollars	2018		2017
Operating revenues	$	304.1	$	298.0
Net income	17.0		15.1

Revenues and net income increased primarily due to colder weather.

Other Operating Expenses

Other operating expenses were as follows:

	The Company				Consolidated SCE&G
Millions of dollars	2018		2017		2018		2017
Other operation and maintenance	$	200.8	$	175.2	$	145.8	$	141.8
Impairment loss	3.6		—		3.6		—
Depreciation and amortization	99.2		94.4		80.5		77.0
Other taxes	69.9		65.9		64.9		61.3

Other operation and maintenance increased primarily due to certain legal and other costs incurred in connection with the proposed merger with Dominion Energy. Changes in other operating expenses are also largely attributable to the electric operations and gas distribution segments and are addressed in those discussions.

Other Income (Expense)

Other income (expense) includes the results of certain incidental non-utility activities of regulated subsidiaries, the activities of certain non-regulated subsidiaries, the costs of certain governance activities at the parent company and AFC. AFC is a utility accounting practice under which a portion of the cost of both equity and borrowed funds used to finance construction (which is shown on the condensed consolidated balance sheet as construction work in progress) is capitalized. Each of the Company and Consolidated SCE&G includes an equity portion of AFC in nonoperating income and a debt portion of AFC in interest charges (credits), both of which have the effect of increasing reported net income. Components of other income (expense) and AFC were as follows:

52

	The Company						Consolidated SCE&G
Millions of dollars	2018			2017			2018			2017
Other income	$	134.0		$	17.0		$	127.4		$	7.7
Other expense	(10.5		)	(13.7		)	(6.9		)	(9.5		)
AFC - equity funds	4.2			9.1			2.9			8.6

Other income at the Company and at Consolidated SCE&G increased primarily due to the recognition of $113.7 million of gains realized upon the settlement of certain interest rate derivative contracts and $8.2 million of gains from land sales. The gains related to the settlement of interest rate derivative contracts were fully offset by downward adjustments to electric revenues pursuant to a previously received SCPSC order related to fuel cost recovery and had no effect on net income. These increases were partially offset by $4.1 million of lower carrying costs on certain regulatory assets. Other expense at the Company and at Consolidated SCE&G decreased $2.2 million and $2.0 million, respectively, due to varying levels of non-service costs components of pension and other postretirement benefit expense recognized within other expense. AFC decreased primarily due to the abandonment of the Nuclear Project.

Interest Expense

     Interest charges increased primarily due to the accrual of interest related to uncertain tax positions. In 2017, certain of such interest accruals were deferred in regulatory assets, and such deferred amounts were subsequently included in an impairment loss recorded in the fourth quarter of 2017.

Income Taxes

Income tax expense decreased in 2018 due to lower income before taxes and an impairment loss (see Note 10 to the condensed consolidated financial statements) as well as a lower effective tax rate.  The lower effective tax rate in 2018 was primarily due to the federal corporate tax rate changing from 35% to 21% as a result of the Tax Act.

LIQUIDITY AND CAPITAL RESOURCES

The Company and Consolidated SCE&G have experienced significant adverse events leading up to their decision to stop construction of Unit 2 and Unit 3, as well as significant adverse events since that decision was made. These difficulties and other developments occurring prior to the bankruptcy filing by WEC and WECTEC and other matters are described in Liquidity and Capital Resources and in Note 10 to the consolidated financial statements included in the Company's and Consolidated SCE&G's combined Form 10-K for the year ended December 31, 2017. Significant developments affecting liquidity subsequent to December 31, 2017 are discussed below.

Liquidity Considerations

The Company and Consolidated SCE&G have significant obligations that must be paid within the next 12 months, including long-term debt maturities and capital lease payments of $727 million for the Company (including $723 million for Consolidated SCE&G), short-term borrowings of $248 million for the Company (including $146 million for Consolidated SCE&G), interest payments of approximately $301 million for the Company (including $256 million for Consolidated SCE&G), and future minimum payments for operating leases of $33 million for the Company (including $26 million for Consolidated SCE&G). Working capital requirements, such as those for fuel supply and similar obligations, also arise due to the lag between when such amounts are paid and when related collection of such costs through customer rates occurs.

Current maturities of long-term debt at the Company and Consolidated SCE&G include $160 million at GENCO due June 1, 2018. Capital markets for entities whose assets are comprised solely of coal-fired facilities have become increasingly constrained. As a result, the debt at GENCO may be paid at maturity through a combination of money pool borrowings and a capital contribution from SCANA.

              Management believes as of the date of issuance of these financial statements that it has access to available sources of cash to pay obligations when due over the next 12 months. These sources include committed long-term lines of credit that expire in December 2020 totaling $1.8 billion for the Company (including $1.2 billion for Consolidated SCE&G). In addition, as of the date of issuance of these financial statements, SCE&G continues to collect in customer rates amounts previously approved under the BLRA, as well as amounts provided for in other orders related to non-BLRA electric and gas rates. In 2018,

53

however, certain of SCANA's credit ratings have fallen to below investment grade, which has constrained its ability and that of Fuel Company to issue commercial paper.

As described in Note 10, on January 31, 2018, the South Carolina House of Representatives passed a bill (H.4375) that would create an experimental rate by effectively suspending collections from rates previously approved by the SCPSC under the BLRA. This experimental rate would remain in effect during the pendency of administrative proceedings currently before the SCPSC or any appeal therefrom. On April 18, 2018, the South Carolina Senate passed a joint resolution (S. 954) which would, among other things, (1) create a temporary experimental rate that reduces SCE&G electric rates related to nuclear construction costs from 18% to 5%, which reduction would remain in effect from April 1, 2018 until the SCPSC issues a final order on the merits of a docket currently before the SCPSC made pursuant to the BLRA (which docket (i.e., Joint Petition) is discussed below); (2) require the SCPSC to conduct a hearing within 30 days of the experimental rate being ordered to determine if an adjustment to the rate is necessary to ensure SCANA does not become insolvent prior to the SCPSC issuing a final order on the merits of such docket; (3) prohibit the SCPSC from holding a hearing on the merits for such docket (other than administrative or procedural hearings), or making any final determination on any related requests, before November 1, 2018; and (4) require the SCPSC to issue a final order for such docket no later than December 21, 2018. Also, S. 954 would require the SCPSC to order each investor-owned utility to provide an accounting of its estimated tax savings for calendar year 2018 and to provide that customers of such utility receive these estimated savings, subject to a true up in 2019 for the actual savings and benefits realized. On April 25, 2018, the House voted to "non-concur" on S. 954. As a result, differences between the legislation approved by the House and Senate will be the subject of conference committee proceedings. Any bill or joint resolution, including any legislation resulting from a conference committee proceeding, must be approved by both legislative chambers and be signed by, or allowed to become law without the signature of, the Governor before it would be enacted. Neither the Company nor Consolidated SCE&G can predict if or when either of these pieces of legislation will become law, or what additional actions, if any, may be proposed or taken, including other legislative actions related to the BLRA.

Were the SCPSC to grant the relief sought by ORS in the Request or grant similar relief resulting from legislative action, as further discussed in Note 10 in the condensed consolidated financial statements, an additional impairment loss or other charges totaling as much as approximately $4.9 billion (approximately $3.7 billion net of tax) may be required. Such an impairment loss or other charges would further stress the Company’s and Consolidated SCE&G’s debt to total capitalization ratio and may result in the Company’s and Consolidated SCE&G’s ratio of debt to total capitalization exceeding maximum levels prescribed in their respective credit agreements. Such an event likely would limit the Company’s and Consolidated SCE&G’s ability to borrow under their commercial paper programs and credit facilities and their ability to pay future dividends or may trigger events of default under such agreements.

Known and knowable conditions and events when considered in the aggregate as of the date of issuance of these financial statements do not suggest it is probable that the Company and Consolidated SCE&G will not be able to meet obligations as they come due over the next 12 months. However, possible future actions related to rates or refunds could have a material adverse effect on the Company’s and Consolidated SCE&G’s financial condition, liquidity, results of operations and cash flows such that management’s conclusion with respect to its ability to pay obligations when due could change.

Impact of Abandonment of Nuclear Project

Regulatory proceedings being considered by the SCPSC include the Request filed by the ORS which, if granted, would require SCE&G to (1) immediately suspend all revised rates collections from customers which were previously approved by the SCPSC pursuant to the authority of the BLRA, and (2) make credits to future bills or refunds to customers for prior revised rates collections in the event that the BLRA is found to be unconstitutional or the South Carolina General Assembly amends or revokes it. SCE&G estimates that revised rates collections, including collections related to transmission assets which have been or are expected to be placed into service, currently total approximately $445 million annually, and such amounts accumulated as of March 31, 2018 total approximately $2.0 billion. In an amendment to the Request, the ORS has asked the SCPSC to consider the most prudent manner by which SCE&G will enable its customers to realize the value of the monetized Toshiba Settlement payments and other payments made by Toshiba towards satisfaction of its obligations to SCE&G. SCE&G's 55% share of such amounts total $1.094 billion, net of certain expenses.

On September 28, 2017, SCE&G filed a motion to dismiss the Request. After conducting a hearing, the SCPSC denied SCE&G's motion to dismiss the Request on December 20, 2017 and requested that the ORS carry out an inspection, audit and examination of SCE&G's revenue requirements to assist the SCPSC in determining whether SCE&G's present schedule of rates is fair and reasonable. Parties who have intervened and continue to intervene in the Request or who filed a letter in support of the Request, as amended, include the Governor, the state's Office of Attorney General and Speaker of the House of Representatives, the Electric Cooperatives of South Carolina, Santee Cooper, the SCEUC, certain large industrial customers, and several environmental groups. The hearing on the Request has not been scheduled. SCE&G intends to continue vigorously

54

contesting the Request, but cannot give any assurance as to the timing or outcome of this matter. Any adverse action by the SCPSC, such as that sought by the ORS in the Request, could have a material adverse impact on the Company's and Consolidated SCE&G's results of operations, cash flows and financial condition.

Should the SCPSC or a court direct that proceeds arising from the Toshiba Settlement be refunded to customers in the near-term, or direct that such funds be escrowed or otherwise made unavailable to SCE&G, it is anticipated that SCE&G would issue commercial paper, draw on its credit facilities or issue long-term debt to fund such requirement if such sources are available. However, were the SCPSC to rule in favor of the ORS in response to the Request that SCE&G suspend collections from customers of amounts previously authorized under the BLRA, or were other actions of the SCPSC or others taken in order to significantly restrict SCE&G’s access to revenues or impose additional adverse refund obligations on SCE&G, the Company’s and Consolidated SCE&G's assessments regarding the recoverability of all or a portion of the remaining balance of unrecovered Nuclear Project costs (see Note 2 to the condensed consolidated financial statements) would be adversely impacted and additional impairment losses would likely be recorded. Further, the recognition of significant additional impairment losses with respect to unrecovered Nuclear Project costs could increase the Company’s and Consolidated SCE&G’s debt to total capitalization to a level which may limit their ability to borrow under their commercial paper programs or under their credit facilities and also could constitute a default under these credit facilities. Borrowing costs for long-term debt issuances and access to capital markets could also be negatively impacted.

For additional background on the Nuclear Project and further details on the matters described above, see Note 10 to the condensed consolidated financial statements under Abandoned Nuclear Project - Toshiba Settlement and Subsequent Monetization and Regulatory, Political and Legal Developments.

Adverse developments relating to the WEC bankruptcy and a decline in the regulatory and legislative environment in 2017 and 2018 have caused credit ratings agencies to place SCANA and SCE&G’s credit ratings on negative outlook or watch status. On January 3, 2018, after SCANA announced a proposed merger with Dominion Energy, each of the three agencies affirmed or reported no change to their respective credit ratings, and one agency revised its rating outlook for SCANA and its rated operating companies from negative to evolving. However, on January 31, 2018, the South Carolina House of Representatives overwhelmingly approved a bill (H. 4375) that, if enacted, would temporarily repeal rates SCE&G collects under the BLRA. As a result, on February 5, 2018, one agency downgraded its ratings for SCANA and SCE&G, and attributed the downgrade to the action taken by the House of Representatives and the politically charged environment that is expected to weigh heavily on any decisions by the SCPSC related to SCE&G's electric rates. As of March 31, 2018, the issuer ratings and the senior unsecured debt ratings for SCANA are considered below investment grade by two credit agencies; the issuer ratings for SCE&G are considered to be at the threshold for investment grade by two credit agencies while its senior secured debt ratings remain above investment grade; and the issuer ratings for PSNC Energy are considered to be at the threshold for investment grade by one credit agency while its senior secured debt ratings remain above investment grade. All of the ratings for SCANA, SCE&G and PSNC Energy are either under review for possible downgrade or have a negative or evolving outlook.

Any adverse final judgment by a court in any matter of litigation, or any levy for amounts assessed by a regulatory agency, including but not limited to matters described in Part II, Item 1. Legal Proceedings, could require the Company and/or Consolidated SCE&G to post a bond equal to the monetary amount of the judgment or assessment while the decision is being appealed or challenged.

Any actions taken by or anticipated to be taken by regulators or legislators that are viewed as adverse, including a change to the BLRA or a requirement that SCE&G make credits to future bills or refunds to customers or any requirement that SCE&G make such credits or refunds in the absence of the merger being consummated, or deterioration of the rated companies’ commonly monitored financial credit metrics or any additional adverse developments with respect to the Nuclear Project, could further negatively affect their debt ratings. If these rating agencies were to further lower any of these ratings, borrowing costs on new issuances of long-term debt and commercial paper would increase, which could adversely impact financial results or limit or eliminate refinancing opportunities, and the potential pool of investors and funding sources could decrease. In addition, further ratings downgrades may result in lower collateral thresholds being applied to the Company's and Consolidated SCE&G's commodity derivatives, or the removal of such thresholds altogether. This action would have the effect of requiring the Company to post additional collateral for commodity derivative instruments with unfavorable fair values. Ratings downgrades have also resulted in prepayments and demands from vendors for letters of credit, cash deposits, or other forms of credit support under certain gas supply and other agreements. In February 2018 SCANA obtained a letter of credit of $43.4 million in favor of a natural gas distributor, which is in addition to a $3 million letter of credit that previously existed, and in March 2018, SCE&G borrowed $100 million under a credit agreement to fund a deposit with one of its natural gas transporters. These actions have reduced amounts available under the credit facilities (see Note 5 to the condensed consolidated financial

55

statements). Further ratings downgrades could result in requirements for additional deposits or the provision of additional credit support in order to conduct business under these agreements.

Significant Tax Deductions and Credits

The Company and Consolidated SCE&G have claimed significant research and experimentation tax deductions and credits related to the design and construction activities of Unit 2 and Unit 3. A significant portion of these claims followed the issuance of final IRS regulations in 2014 regarding such treatment with respect to expenditures related to the design and construction of pilot models. (See also Note 6 to the condensed consolidated financial statements.) The Company and Consolidated SCE&G also expect to claim a significant tax deduction related to the decision to stop construction and to abandon the Nuclear Project in 2017.

These tax claims primarily involve the timing of recognition of tax deductions rather than permanent tax attributes, and their permanent attributes (net), as well as most of the interest accruals required to be recorded with respect to them, had been deferred within regulatory assets until December 31, 2017, at which time it was determined to treat these deferrals as impaired. These claims have contributed significantly to the Company’s and Consolidated SCE&G’s cash flows by providing a significant source of capital and lessening the level of debt and equity financing that the Company and Consolidated SCE&G have needed to raise in the financial markets. 

The claims made to date are under examination, and are considered controversial, by the IRS. Tax deductions which are expected to be claimed in connection with the determination to abandon the construction of Unit 2 and Unit 3 may also be considered controversial; therefore, it is also expected that the IRS will examine future tax returns.  To the extent that any of these claims are not sustained as ordinary losses on examination or through any subsequent appeal, the Company and Consolidated SCE&G will be required to repay any cash received for tax benefit claims which are ultimately disallowed, along with interest on those amounts. Such amounts could be significant and could adversely affect the Company's and Consolidated SCE&G's liquidity, cash flows, results of operations and financial condition. In certain circumstances, which management considers to be remote, penalties for underpayment of income taxes could also be assessed. Additionally, in such circumstances, the Company and Consolidated SCE&G may need to access the capital markets to fund those tax and interest payments, which could in turn adversely impact their ability to access those markets for other purposes.

Other Liquidity Requirements and Restrictions

The terms of the Merger Agreement place limits on the Company and its subsidiaries as to certain investing and financing transactions. While the Merger Agreement permits the Company and its subsidiaries to refinance and issue certain long-term debt, make capital expenditures at certain levels, consummate certain planned investments, and make regular quarterly dividend payments to its shareholders at certain levels, transactions above these levels would require consent from Dominion Energy, which consent cannot be unreasonably withheld. Permitted transactions include, but are not limited to, the planned refinancing of $710 million of long-term debt maturing in 2018 at Consolidated SCE&G and the planned new issuance of $100 million of long-term debt at PSNC Energy, the purchase of an existing 540-MW gas fired power plant, and the payment by SCANA of regular quarterly dividends to its shareholders subject to certain limits. In addition, SCANA’s Supplementary Key Executive Severance Benefits Plan provides certain payments to qualified senior executive officers in connection with a change in control. In January 2018, approximately $110.7 million was placed in a rabbi trust, designated as irrevocable subject to the change in control, to fund payments pursuant to this and certain other deferred compensation, incentive and retirement plans, which might arise in connection with a change in control and/or a termination of employment or service if and when such payments become due. Under the terms of the rabbi trust, if the change in control does not occur, SCANA could request a return of all or part of those funds.

The Company expects to meet contractual cash obligations in 2018 through internally generated funds and additional short- and long-term borrowings. Subject to the outcome of the regulatory, legislative and legal proceedings discussed above, the Company expects that, barring a future impairment of the capital markets or its access to such markets, it has or can obtain adequate sources of financing to meet its projected cash requirements for the foreseeable future, including the cash requirements for refinancing maturing long-term debt. As noted above, adverse developments in regulatory, legislative or legal proceedings could alter these conclusions. The Company's ratio of earnings to fixed charges for the three and 12 months ended March 31, 2018 was 3.19 and 0.37, respectively. Consolidated SCE&G's ratio of earnings to fixed charges for the three and 12 months ended March 31, 2018 was 3.10 and (0.07), respectively. These ratios reflect impairment losses recorded in 2017 and 2018 related to the Nuclear Project are discussed in Note 10 to the condensed consolidated financial statements and in SCANA's and SCE&G's combined Form 10-K for the year ended December 31, 2017.

56

 SCANA's ability to pay dividends on its common stock may be limited by existing or future covenants limiting the right of its subsidiaries to pay dividends on their common stock. Further, SCANA has agreed to obtain the consent of Dominion Energy, which consent cannot be unreasonably withheld, prior to making dividend payments to shareholders greater than $0.6125 per share for any quarter while the Merger Agreement is pending. Any significant reduction in SCANA's payment of dividends in the future may result in a decline in the value of its common stock. Such a decline in value could limit SCANA's ability to raise debt and equity capital.

Cash requirements for SCANA’s regulated subsidiaries arise primarily from their operational needs, funding their construction programs and payment of dividends to SCANA. The ability of the regulated subsidiaries to replace existing plant investment, to expand to meet future demand for electricity and gas and to install equipment necessary to comply with environmental regulations, will depend on their ability to attract the necessary financial capital on reasonable terms. Regulated subsidiaries recover the costs of providing services through rates charged to customers. Rates for regulated services are generally based on historical costs. As customer growth and inflation occur and these subsidiaries continue their ongoing construction programs, rate increases will be sought. The future financial position and results of operations of regulated subsidiaries will be affected by their ability to obtain adequate and timely rate and other regulatory relief.

Rating agencies consider qualitative and quantitative factors when assessing SCANA and its rated operating companies’ credit ratings, including the legislative and regulatory environment, capital structure and the ability to meet liquidity requirements. As previously noted, adverse developments with respect to recovery of Nuclear Project costs have negatively affected the Company’s and Consolidated SCE&G's debt ratings. Further adverse developments, changes in the legislative and regulatory environment or deterioration of SCANA's or its rated operating companies' commonly monitored financial credit metrics could cause the Company and Consolidated SCE&G to pay higher interest rates on its long- and short-term indebtedness, could limit the Company's and Consolidated SCE&G's access to capital markets and liquidity, and could trigger more stringent collateral requirements on interest rate and commodity hedges and under gas supply agreements and other contracts.

Cash provided from operating activities in 2017 reflects significant tax benefits (reductions in income tax payments and tax refunds) arising from the deductions previously described under Significant Tax Deductions and Credits. The Company's decision in 2017 to stop construction of Unit 2 and Unit 3 and to abandon the Nuclear Project is expected to result in a significant tax deduction and an associated NOL for tax purposes. The Company expects to obtain a refund of taxes paid in certain prior years as a result of the carryback of the NOL, and expects to benefit from the carryforward of the NOL in future years. These cash flows are expected to supplant portions of financing which would otherwise be obtained in the capital markets.

Enactment of the Tax Act resulted in the remeasurement of deferred income tax assets and liabilities and the recognition as regulatory liabilities of certain excess deferred income taxes (see Note 2 and Note 6 to the condensed consolidated financial statements). Certain of these regulatory liabilities will be amortized to the benefit of customers in accordance with the normalization provisions of the IRC and Code of Federal Regulations, which will serve to mitigate significant negative cash impact. However, since the majority of the Company’s and Consolidated SCE&G's businesses are rate regulated, lower income taxes payable in future years due to the Tax Act will also result in lower collections from customers in rates.

Cash flows from operating activities in 2018 reflect the posting of a trade deposit with a natural gas transporter.

Cash flows from investing activities in both periods were primarily related to capital expenditures. In 2018, investing inflows included proceeds received upon the settlement of certain interest rate swaps, while investing outflows included an investment in the rabbi trust, as discussed above.

Cash flows from financing activities in 2017 and 2018 included dividend payments and increases in commercial paper balances. Proceeds from the issuance of long-term debt under a credit facility were seen in 2018.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

SCANA:

Interest Rate Risk - Interest rates on all outstanding long-term debt are fixed either through the issuance of fixed rate debt or through the use of interest rate derivatives. The Company is not aware of any facts or circumstances that would significantly affect exposures on existing indebtedness in the near future.

For further discussion of changes in long-term debt and interest rate derivatives, including changes in the Company's market risk exposures relative to interest rate risk, see the Liquidity and Capital Resources section in Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Notes 2, 5, 7 and 8 of the condensed consolidated financial statements.

Commodity price risk - The Company uses derivative instruments to hedge forward purchases and sales of natural gas, which create market risks of different types. See Note 7 and 8 of the condensed consolidated financial statements. The following tables provide information about the Company’s financial instruments, which are limited to financial positions of SCANA Energy and PSNC Energy, that are sensitive to changes in natural gas prices.  Weighted average settlement prices are per 10,000 MMBTU. Fair value represents quoted market prices for these or similar instruments.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

SCANA and SCE&G:

The following describes certain legal proceedings that originated or have been terminated during the three months ended March 31, 2018 or for which developments have occurred during the period. The Company and Consolidated SCE&G intend to vigorously contest the lawsuits which have been filed against them. For developments related to these or other proceedings subsequent to March 31, 2018, if any, see Note 2 and Note 10 to the condensed consolidated financial statements. No reference to, or disclosure of, any proceeding, item or matter described below shall be construed as an admission or indication that such proceeding, item or matter is material or that such proceeding, item or matter is required to be referred to or disclosed in this Form 10-Q.

Ratepayer Class Actions

On August 11, 2017, a purported class action was filed against SCE&G by plaintiff LeBrian Cleckley (the “Cleckley Lawsuit”), on behalf of himself and all others similarly situated, in the State Court of Common Pleas in Richland County, South Carolina (the “Richland County Court”). The plaintiff alleges, among other things, that SCE&G was negligent and unjustly enriched and breached alleged fiduciary and contractual duties by failing to properly manage the Nuclear Project. The plaintiff seeks to recover, on behalf of the purported class, unspecified damages and attorneys’ fees, specific performance of the alleged implied contract to construct the now abandoned project, and any other relief the court deems proper. By order dated October 31, 2017, the South Carolina Supreme Court consolidated all pending state court ratepayer class actions and assigned the consolidated cases to a single Circuit Court judge. On March 2, 2018, the Circuit Court judge issued orders denying SCE&G’s Motion to Dismiss the pending state court ratepayer class actions. The Circuit Court's order denied SCE&G’s motion on the grounds that the Circuit Court does have subject matter jurisdiction to determine plaintiffs’ claims; that plaintiffs have stated causes of action that state a claim upon which relief can be granted; that the filed rate doctrine does not bar plaintiffs’ claims; and that the Circuit Court has concurrent jurisdiction with the SCPSC on specific issues raised in plaintiffs’ complaint. On March 8, 2018, SCE&G received an order that its appeal of this decision was dismissed by the South Carolina Court of Appeals. On March 12, 2018, the Circuit Court judge indicated that discovery could proceed. At March 31, 2018, the following motions regarding this matter were pending: Plaintiff’s Motion for Class Certification, filed November 1, 2017; and Plaintiff's Motion to Appoint a Receiver, filed November 1, 2017.

On August 14, 2017, a purported class action was filed against SCE&G by plaintiff Richard Lightsey (the "Lightsey Lawsuit"), on behalf of himself and all others similarly situated, in the State Court of Common Pleas in Hampton County (the "Hampton County Court"). The plaintiff makes substantially similar allegations as those alleged in the Cleckley Lawsuit and, in addition, alleges that SCE&G committed unfair trade practices and violated state anti-trust laws. The plaintiff seeks a declaratory judgment that SCE&G may not charge its customers for any past or continuing costs of the Nuclear Project. The plaintiff also seeks compensatory, punitive and statutory treble damages, attorneys’ fees, and any other relief the court deems proper. On August 25, 2017, SCE&G filed a motion to transfer venue to Lexington County, South Carolina. The Circuit Court's ruling on SCE&G's Motion to Dismiss in the Cleckley Lawsuit has been applied to this case, and this case is expected to proceed along the same discovery timeline as the Cleckley Lawsuit. At March 31, 2018, the following motions regarding this matter were pending: Plaintiff’s Motion for Class Certification, filed August 23, 2017; and Plaintiff’s Motion to Compel, filed October 12, 2017.

On August 28, 2017, a purported class action was filed against SCANA and SCE&G by plaintiff Edwinda Goodman, on behalf of herself and all others similarly situated, in the State Court of Common Pleas in Fairfield County (the “Fairfield County Court”). The plaintiff makes substantially similar allegations as those alleged in the Cleckley Lawsuit and, in addition, alleges that SCE&G committed fraud and misrepresentation in failing to properly manage the Nuclear Project. The plaintiff seeks to have the defendants’ assets frozen and all monies recovered from Toshiba and other sources be placed in a constructive trust for the benefit of ratepayers. The plaintiff also seeks compensatory, punitive and treble damages, attorneys’ fees, and any other relief the court deems proper. The Circuit Court's ruling on SCE&G's Motion to Dismiss in the Cleckley Lawsuit has been applied to this case, and this case is expected to proceed along the same discovery timeline as the Cleckley Lawsuit. At March 31, 2018, the following motions regarding this matter were pending: Plaintiff's Motion to Appoint Receiver and Expedite Hearing, served November 2, 2017; and Plaintiff’s Motion for Temporary and Permanent Injunction, filed December 15, 2017.

On September 7, 2017, a purported class action was filed against Santee Cooper, SCE&G, Palmetto Electric Cooperative, Inc. and Central Electric Power Cooperative, Inc. by plaintiff Jessica Cook, on behalf of herself and all others similarly situated, in the Hampton County Court (the "Cook Lawsuit"). The plaintiff makes substantially similar allegations as the Cleckley Lawsuit and the Lightsey Lawsuit. The plaintiff seeks a declaratory judgment that defendants may not charge the

60

purported class for reimbursement for past or future costs of the Nuclear Project, as well as other compensatory and statutory treble damages, attorneys’ fees, and any other relief the court deems proper. The Circuit Court's ruling on SCE&G's Motion to Dismiss in the Cleckley Lawsuit has been applied to this case, and this case is expected to proceed along the same discovery timeline as the Cleckley Lawsuit. On March 27, 2018, the plaintiff and additional named plaintiffs (those that had been pursuing claims in the hereinafter defined Kolbe Lawsuit, which is discussed below) filed an amended complaint including as additional named defendants current and former directors of Santee Cooper and SCANA.

On September 25, 2017, a purported class action was filed against SCANA by plaintiff Christine Delmater, on behalf of herself and all others similarly situated, in the District Court.

The plaintiff seeks compensatory and consequential damages, and any other relief the court deems proper. Plaintiff filed its Second Amended Complaint on November 7, 2017, and filed a Motion for Injunctive Relief on November 8, 2017. SCANA filed a motion to dismiss the Second Amended Complaint and an opposition to the Motion for Injunctive Relief on December 21, 2017. Plaintiff has requested a status conference with the court to discuss potential consolidation for hearings on Defendants' Motions to Dismiss this case and the Glibowski Lawsuit (as hereinafter defined). At March 31, 2018, a date for this conference had not been set.

On October 9, 2017, plaintiffs Chris Kolbe and Ruth Ann Keffer filed an amended complaint in a purported class action, on behalf of themselves and all others similarly situated, against Santee Cooper and certain of its directors and officers, in the Berkeley County Court of Common Pleas, naming SCE&G and SCANA as additional defendants (the "Kolbe Lawsuit"). The plaintiffs allege, among other things, that SCE&G and SCANA were grossly negligent, reckless, breached contracts, were unjustly enriched, and violated principles of equity in connection with their management of the Nuclear Project. The plaintiffs seek compensatory damages, attorneys’ fees, and a declaratory judgment as to Santee Cooper’s rates. The plaintiffs have since joined the Cook Lawsuit and on March 27, 2018, voluntarily dismissed the Kolbe Lawsuit.

On January 31, 2018, a purported class action was filed against SCANA, SCE&G, Kevin Marsh, Jimmy Addison, Stephen Byrne, Martin Phalen, Mark Cannon, Russell Harris, Jeffrey B. Archer, Sarena Burch, W. Keller Kissam, Ronald T. Lindsay, and James Micali by Plaintiff Timothy Glibowski, on behalf of himself and all others similarly situated, in District Court (the "Glibowski Lawsuit"). The plaintiff alleges, among other things, that the Company, SCE&G and the individual defendants participated in an unlawful racketeering enterprise in violation of RICO 18 U.S.C. §1961 et seq., and conspired to violate RICO 18 U.S.C. §1962(c) by fraudulently inflating utility bills to generate unlawful proceeds. Plaintiff seeks treble damages, attorneys’ fees, and any other relief the court deems proper. SCANA, SCE&G and Mr. Archie (improperly named as Jeffrey B. Archer in the complaint) have moved to dismiss the complaint. As of March 31, 2018, the motion remains pending.

The plaintiff alleges, among other things, that the defendants breached their fiduciary duties to shareholders by their gross mismanagement of the Nuclear Project, and that the defendants Marsh, Addison, and Byrne were unjustly enriched by bonuses they were paid in connection with the project. The plaintiff seeks compensatory and consequential damages, attorneys’ fees, and any other relief the court deems proper. Defendants filed a Motion for Consolidation and appointment of lead plaintiff's counsel in this case and the Todd Lawsuit (as hereinafter defined) on November 29, 2017, and also filed a motion to have these cases transferred to the Richland County Business Court. On January 8, 2018, the court notified the parties that the Crangle Lawsuit and the Todd Lawsuit would be transferred to the Business Court Pilot Program in Richland County. On March 5, 2018, Defendants' Motion to Stay these shareholder derivative actions pending the resolution of the ongoing related regulatory proceedings, ratepayer class actions, securities class actions, and government investigations was denied.

On January 26, 2018, the DOR notified SCANA that it was initiating an audit of SCE&G's sales and use tax returns for the periods September 1, 2008 through December 31, 2017. The Company and Consolidated SCE&G understand that the DOR's position is that the exemption for sales and use tax for purchases related to the Nuclear Project should not apply because Unit 2 and Unit 3 will not be placed into service and no electricity will be manufactured for sale. The Company and Consolidated SCE&G intend to vigorously contest the DOR's position.

Employment Class Action

On August 8, 2017, a purported class action was filed against SCANA, SCE&G, and its co-defendants Fluor and Fluor Enterprises, Inc., by plaintiffs Harry Pennington III and Timothy Lorenz, on behalf of themselves and all others similarly situated, in the District Court.

ITEM 1A. RISK FACTORS

The risk factors from the Registrants' combined Annual Report on Form 10-K for the year ended December 31, 2017, have been updated and are restated below in their entirety.

The risk factors that follow relate in each case to the Company, and where indicated the risk factors also relate to Consolidated SCE&G.

The completion of the merger is subject to the receipt of consents, approvals and/or findings from governmental entities, which may impose conditions that could have an adverse effect on Dominion Energy or SCANA or could cause either Dominion Energy or SCANA to terminate the merger. The completion of the merger is also subject to there having not been certain substantive changes in certain South Carolina laws that have or would reasonably be expected to have an adverse effect on SCANA or its subsidiaries or changes in law that impose any condition that would reasonably be expected to result in specified changes to the Joint Petition. Additionally, any such changes in certain South Carolina law could

affect the considerations which were relied upon by SCANA and/or Dominion Energy prior to the signing of the Merger Agreement.

Dominion Energy and SCANA are not required to complete the merger until after the requisite authorizations, approvals, consents and/or permits are received from the FERC, NRC, SCPSC, NCUC and GPSC. The GPSC has approved the merger. Any of the remaining relevant governmental entities may oppose the merger, fail to approve the merger, fail to make required findings in favor of the merger, or impose certain requirements or obligations as conditions for their consent, approval or findings or in connection with their review. Regulatory approvals of the merger or findings with respect to the merger may not be obtained on a timely basis or at all, and such approvals or findings may include conditions that could have an adverse effect on the Company or Consolidated SCE&G, and/or result in the termination of the merger. The terms of any conditions imposed in order to obtain the requisite regulatory approvals or findings may not be known by the date of the special meeting of SCANA shareholders to vote on the merger proposal. No assurance can be given that the necessary approvals or findings will be obtained or that any required conditions will not have an adverse effect on Dominion Energy following the merger. If SCANA shareholders vote in favor of the merger proposal at the special meeting, Dominion Energy or SCANA may make decisions after the special meeting to waive a condition or approve certain actions required to obtain regulatory approvals or findings without seeking further approval of the SCANA shareholders.

Subject to the terms and conditions set forth in the Merger Agreement, the Merger Agreement requires Dominion Energy to accept conditions from regulators that could adversely impact Dominion Energy after the merger without either of Dominion Energy or SCANA having the right to refuse to close the merger on the basis of those regulatory conditions, except that Dominion Energy is generally not required, and SCANA is generally not permitted without Dominion Energy’s prior approval, to take any action or accept any condition that results in a burdensome condition.

In addition, the Merger Agreement provides that Dominion Energy (but not SCANA) will have the right to refuse to complete the merger if, since the date of the Merger Agreement, any governmental entity shall have enacted any order, or there shall have been any change in law (including the BLRA and the other laws governing South Carolina public utilities), which imposes any material change to the terms, conditions or undertakings set forth in the Joint Petition, or any significant changes to the economic value of the Joint Petition, in each case as determined by Dominion Energy in good faith.

The Merger Agreement further provides that Dominion Energy (but not SCANA) will have the right to refuse to complete the merger if there shall have occurred any substantive change in the BLRA or other laws governing South Carolina public utilities which has or would reasonably be expected to have an adverse effect on SCANA or any of its subsidiaries. Two pieces of legislation (H. 4375 and S. 954) have passed one chamber of the South Carolina General Assembly, and S. 954 is the subject of conference committee proceedings. Each of these pieces of legislation would make substantive changes to the BLRA or would reduce collections from rates previously approved by the SCPSC under the BLRA. If either of them becomes law, Dominion Energy would not be obligated to complete the merger if it is determined that the enacted legislation has or would reasonably be expected to have an adverse effect on SCANA or any of its subsidiaries.

Certain lawsuits and regulatory actions have been filed against SCANA and SCE&G, and several motions are currently pending, in connection with the abandonment of the Nuclear Project. If the relief requested in these matters (including a request for declaratory judgment that the BLRA is unconstitutional) is granted, Dominion Energy might not be obligated to complete the merger.

No assurance can be given that these risks will not materialize and either adversely impact Dominion Energy after the completion of the merger or, if such conditions rise to the thresholds discussed above, some of which, as described above, are in the subjective determination of Dominion Energy acting in good faith, or if the required authorizations, approvals, consents and/or permits are not obtained or received, result in the termination of the merger and adversely impact the results of operations, cash flows and financial conditions of the Company and Consolidated SCE&G.

Failure to complete the merger could negatively impact the stock price and the future business and financial results of SCANA.

If the merger is not completed, the ongoing business of the Company and Consolidated SCE&G may be adversely affected and the Company and Consolidated SCE&G could be subject to several risks, including the following:

• the price of SCANA common stock may decline to the extent that the current market price reflects an expectation by the market that the merger will be completed;

• obligations to pay certain costs relating to the merger, such as legal, accounting, financial advisory, filing, proxy solicitation, printing and mailing fees;  

65

• the disruption of the Company’s and Consolidated SCE&G’s ongoing business or inconsistencies in its services, standards, controls, procedures and policies due to management’s focus on the merger, any of which could adversely affect the ability of the Company and Consolidated SCE&G to maintain relationships with customers, regulators, vendors and employees, or could otherwise adversely affect the business and financial results of the Company or Consolidated SCE&G, without realizing any of the benefits of having the merger completed;

• the potential negative impact on the Company and Consolidated SCE&G ultimately resolving the rate and regulatory issues, including pending investigations and legal challenges, relating to the abandonment of the Nuclear Project in a manner satisfactory to SCANA on account of SCANA working with Dominion Energy to pursue the resolution of these issues as contemplated by the Merger Agreement rather than pursuing its regulatory and legal options for resolving these issues independently of considerations and obligations related to the merger; and

• the loss of other opportunities that could be beneficial to the Company and Consolidated SCE&G that could have been pursued during the pendency of the merger, without realizing any of the benefits of having the merger completed.

In addition to the above risks, SCANA may be required, under certain circumstances, to pay to Dominion Energy a termination fee of $240 million.

If the merger is not completed, no assurance can be given that these risks will not materialize and will not materially affect SCANA's business, financial results and stock price.

The Merger Agreement contains provisions that limit SCANA’s ability to pursue alternatives to the merger, which could discourage a potential competing acquirer of SCANA or could result in any competing proposal being at a lower price than it might otherwise be.

The Merger Agreement contains provisions that, subject to certain exceptions, restrict SCANA’s ability to initiate, solicit, knowingly encourage, facilitate or discuss competing third-party proposals to acquire all or a significant part of SCANA, or provide information to a third party that could reasonably be expected to lead to such a proposal. In addition, Dominion Energy generally has an opportunity to offer to modify the terms of the merger in response to any superior acquisition proposal that may be made before the SCANA board of directors is permitted to withdraw or qualify its recommendation. In some circumstances on termination of the Merger Agreement, SCANA may be required to pay to Dominion Energy a termination fee of $240 million.

These provisions, which the SCANA board regards as customary for transactions of this type, could discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of SCANA from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the merger consideration, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable by SCANA in certain circumstances.

The pendency of the merger could adversely affect the business and operations of SCANA.

In connection with the pending merger, some current or prospective customers or vendors of SCANA’s utilities may delay or defer decisions regarding their existing or proposed relationships with those utilities, which could negatively impact the operations, revenues, earnings, cash flows and expenses of the Company and Consolidated SCE&G, regardless of whether the merger is completed. Similarly, current and prospective employees of SCANA and its utilities may experience uncertainty about their future roles following the merger, which may adversely affect the ability of SCANA and its utilities to attract and retain key personnel during the pendency of the merger. In addition, due to operating covenants in the Merger Agreement, during the pendency of or following the merger, SCANA and its utilities may be unable to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing or other specified transactions or pursue actions that are not in the ordinary course of business, even if such actions would prove beneficial.

Following the merger, Dominion Energy may be unable to successfully integrate the Company’s and Consolidated SCE&G’s businesses.

Dominion Energy and SCANA currently operate as independent public companies. After the merger, Dominion Energy will be required to devote significant management attention and resources to integrating the Company’s and Consolidated SCE&G’sbusiness. Potential difficulties Dominion Energy may encounter in the integration process include the following:

66

• the complexities associated with integrating SCANA and its utility businesses, while at the same time continuing to provide consistent, high quality services;

• the complexities of integrating a company with different core services, markets and customers;

• the inability to attract and retain key employees;

• potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the merger;

• difficulties in managing political and regulatory conditions related to SCANA’s utility businesses after the merger;

• the cost recovery plan includes a moratorium on filing requests for adjustments in SCANA’s base electric rates until 2021 if the merger is approved by the SCPSC, which would limit Dominion Energy’s ability to recover increases in non-fuel related costs of electric operations for SCE&G’s customers; and

• performance shortfalls as a result of the diversion of Dominion Energy management’s attention caused by completing the merger and integrating SCANA’s utility businesses.

For these reasons, it is possible that the integration process following the merger could result in the distraction of Dominion Energy’s management, the disruption of Dominion Energy’s ongoing business or inconsistencies in its services, standards, controls, procedures and policies, any of which could adversely affect the ability of Dominion Energy to maintain or establish relationships with current and prospective customers, vendors and employees or could otherwise adversely affect the business and financial results of Dominion Energy.

Dominion Energy, the Company and Consolidated SCE&G may be adversely affected by negative publicity related to the merger and in connection with other related matters, including the abandonment of the Nuclear Project.

From time to time, political and public sentiment in connection with the merger and in connection with other matters, including the abandonment of the Nuclear Project, may result in a significant amount of adverse press coverage and other adverse public statements affecting Dominion Energy and the Company and Consolidated SCE&G. Adverse press coverage and other adverse statements, whether or not driven by political or public sentiment, may also result in investigations by regulators, legislators and law enforcement officials or in legal claims. Responding to these investigations and lawsuits, regardless of the ultimate outcome of the proceedings, as well as responding to and addressing adverse press coverage and other adverse public statements, can divert the time and effort of senior management from the management of Dominion Energy’s, the Company’s and Consolidated SCE&G’s respective businesses.

Addressing any adverse publicity, governmental scrutiny or enforcement or other legal proceedings is time consuming and expensive and, regardless of the factual basis for the assertions being made, can have a negative impact on the reputation of Dominion Energy, the Company and Consolidated SCE&G, on the morale and performance of their employees and on their relationships with their respective regulators, customers and commercial counterparties. It may also have a negative impact on their ability to take timely advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have an adverse effect on Dominion Energy’s, the Company’s and Consolidated SCE&G’s respective businesses, financial condition, results of operations and prospects.

Pending litigation against SCANA and Dominion Energy could result in an injunction preventing the completion of the merger or requiring the Merger Agreement to be amended, or may require the payment of monetary damages or may adversely affect the combined company’s business, financial condition or results of operations following the merger.

Following the announcement of the merger, multiple lawsuits were filed asserting claims relating to the merger. First, an existing derivative lawsuit was amended to assert direct claims of a purported class of SCANA shareholders in the Court of Common Pleas of the County of Richland, South Carolina against the members of the SCANA board of directors, Dominion Energy and Sedona, alleging breaches of various fiduciary duties by the members of the SCANA board of directors in connection with the merger and alleging that Dominion Energy and Sedona aided and abetted such alleged breaches. Second, purported class actions on behalf of SCANA shareholders have been filed in the Court of Common Pleas of the Counties of Lexington and Richland, South Carolina, respectively, and in the District Court against SCANA, the members of the SCANA board of directors, Dominion Energy and Sedona, and certain current and former officers of SCANA, alleging breaches of various fiduciary duties by the members of the SCANA board of directors in connection with the merger and alleging that SCANA, Dominion Energy and Sedona aided and abetted such alleged breaches. Plaintiffs also allege that SCANA, SCE&G and individual defendants violated or conspired to violate RICO, and that defendants violated provisions of Section 14(a) of the Exchange Act and SEC Rule 14a-9 by allowing or causing misleading proxy statements to be issued. Among other remedies, the plaintiffs seek to enjoin the merger and rescind the Merger Agreement or to have the Merger Agreement amended to provide more favorable terms for plaintiffs, monetary damages, attorney's fees and such further relief as the court deems proper or, in certain cases, seeking compensatory and consequential damages.

67

While the defendants believe that dismissal is warranted, the outcome of any such litigation is inherently uncertain. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger closes may adversely affect the combined company’s business, financial condition or results of operation.

There is uncertainty as to whether the Company and Consolidated SCE&G will be able to recover costs expended for the Nuclear Project, and a reasonable return on those costs, under the abandonment provisions of the BLRA or through other means. In 2017 the Company and Consolidated SCE&G recognized a significant estimated impairment loss with respect to such investment and related costs. In the event the Company and Consolidated SCE&G were to determine that all or an additional portion of their remaining unrecovered Nuclear Project and related costs are to be disallowed and that significant additional impairment losses must be recognized, further material adverse impacts on their results of operations, cash flows and financial condition would occur.

During the term of the Interim Assessment Agreement, SCE&G and Santee Cooper evaluated the various elements of the Nuclear Project, including forecasted costs and completion dates, while construction continued, and SCE&G and Santee Cooper continued to make payments for such work. Based on this evaluation, and in light of Santee Cooper's decision to suspend construction, on July 31, 2017, the Company determined to stop construction of Unit 2 and Unit 3 and to pursue recovery of costs incurred in connection with such construction under the abandonment provisions of the BLRA or through other means. On July 31, 2017, SCE&G gave WEC a five-day notice of termination of the Interim Assessment Agreement, and notified WEC of its determination to stop construction of Unit 2 and Unit 3.

On August 1, 2017, SCE&G senior management provided an allowable ex parte briefing to the SCPSC regarding the Nuclear Project and this decision, and SCE&G also filed a petition with the SCPSC which included its plan of abandonment and certain proposed actions which would mitigate related customer rate increases, including a proposal to return to customers the net value of the proceeds received by SCE&G under or arising from the Toshiba Settlement.

The BLRA provides that, in the event of abandonment prior to plant completion, costs incurred, including AFC, and a return on those costs may be recoverable through rates, if the SCPSC determines that the decision to abandon the Nuclear Project was prudent. Through its August 1, 2017 petition, SCE&G had sought recovery of such costs expended on the construction of the project, including certain costs incurred subsequent to SCE&G's last revised rates update, and a reasonable return on those costs, and certain other costs under the abandonment provisions of the BLRA. Subsequently, SCE&G’s management met with various stakeholders and members of the South Carolina General Assembly, including legislative leaders, to discuss the abandonment of the Nuclear Project and to hear their concerns. In response to those concerns, and to allow for adequate time for governmental officials to conduct their reviews, SCE&G voluntarily withdrew its August 1, 2017 petition from the SCPSC on August 15, 2017.

In August 2017, special committees of the South Carolina General Assembly, both in the House of Representatives and in the Senate, began conducting public hearings regarding the decision to abandon the Nuclear Project. Members of SCE&G's senior management, along with representatives from Santee Cooper, the ORS and other interested parties, testified before these committees. Several legislative proposals adverse to the Company and Consolidated SCE&G resulted from the work of these committees and are being considered by the General Assembly in 2018. In January 2018, these committees reconvened for the purpose of considering the effects of the proposed merger. On January 31, 2018, the House of Representatives passed a bill (H. 4375) that would create an experimental rate which would effectively suspend collections from rates previously approved by the SCPSC under the BLRA. This experimental rate would remain in effect during the pendency of administrative proceedings currently before the SCPSC or any appeal therefrom. On April 18, 2018, the South Carolina Senate passed a joint resolution (S. 954) which would, among other things, (1) create a temporary experimental rate that reduces SCE&G electric rates related to nuclear construction costs from 18% to 5%, which reduction would remain in effect from April 1, 2018 until the SCPSC issues a final order on the merits of a docket currently before the SCPSC made pursuant to the BLRA (which docket (i.e., Joint Petition) is discussed below); (2) require the SCPSC to conduct a hearing within 30 days of the experimental rate being ordered to determine if an adjustment to the rate is necessary to ensure SCANA does not become insolvent prior to the SCPSC issuing a final order on the merits of such docket; (3) prohibit the SCPSC from holding a hearing on the merits for such docket (other than administrative or procedural hearings), or making any final determination on any related requests, before November 1, 2018; and (4) require the SCPSC to issue a final order for such docket no later than December 21, 2018. Also, S. 954 would require the SCPSC to order each investor-owned utility to provide an accounting of its estimated tax savings for calendar year 2018 and to provide that customers of such utility receive these estimated savings, subject to a true up in 2019 for the actual savings and benefits realized by the utility. On April 25, 2018, the House voted to "non-concur" on S. 954. As a result, differences between legislation approved by the House and Senate will be the subject of conference committee proceedings. Any bill or joint resolution, including any legislation resulting from a conference committee proceeding, must be approved by both legislative chambers and be signed by, or allowed to become law

68

without the signature of, the Governor before it would be enacted. Neither the Company nor Consolidated SCE&G can predict if or when either of these pieces of legislation could become law, the precise impact of any change in the law, or what additional actions, if any, may be proposed or taken, including other legislative actions related to the BLRA.

In September 2017, the Company was served with a subpoena issued by the United States Attorney’s Office for the District of South Carolina seeking documents relating to the Nuclear Project. The subpoena requires the Company to produce a broad range of documents related to the project. Also in September 2017, the state's Office of Attorney General, the Speaker of the House of Representatives, and the Chair and Vice-Chair of the South Carolina House Utility Ratepayer Protection Committee requested that SLED conduct a criminal investigation into the handling of the Nuclear Project by SCANA and SCE&G. In October 2017, the staff of the SEC's Division of Enforcement also issued a subpoena for documents related to an investigation they are conducting related to the Nuclear Project. The investigations have continued since those events. The Company and Consolidated SCE&G intend to fully cooperate with these investigations. No assurance can be given as to the timing or outcome of these matters. Also in connection with the abandonment of the Nuclear Project, various state or local governmental authorities have attempted and may further attempt to challenge, reverse or revoke one or more previously-approved tax or economic development incentives, benefits or exemptions and may attempt to apply such action retroactively. No assurance can be given as to the timing or outcome of these matters.

On September 26, 2017, the South Carolina Office of Attorney General issued an opinion stating, among other things, that "as applied, portions of the BLRA are constitutionally suspect," including the abandonment provisions. Also on September 26, 2017, and in reliance on the opinion from the Office of Attorney General, the ORS filed the Request seeking an order from the SCPSC directing SCE&G to immediately suspend all revised rates collections from customers which were previously approved by the SCPSC pursuant to the authority of the BLRA. In the Request, the ORS noted the existence of an allegation that SCE&G failed to disclose information to the ORS that should have been disclosed and that would have appeared to provide a basis for challenging prior requests, and asserted that SCE&G should not be allowed to continue to benefit from nondisclosure. The ORS also asked for an order that, if the BLRA is found to be unconstitutional or the South Carolina General Assembly amends or revokes the BLRA, then SCE&G should make credits to future bills or refunds to customers for prior revised rates collections. SCE&G estimates that revised rates collections, including collections related to transmission assets which have been or are expected to be placed into service, currently total approximately $445 million annually, and such amounts accumulated as of March 31, 2018 total approximately $2.0 billion. On October 17, 2017, the ORS filed a motion with the SCPSC to amend the Request, in which motion the ORS asked the SCPSC to consider the most prudent manner by which SCE&G will enable its customers to realize the value of the monetized Toshiba Settlement payments and other payments made by Toshiba towards satisfaction of its obligations to SCE&G.

On September 28, 2017, SCE&G filed a motion to dismiss the Request. After conducting a hearing, the SCPSC denied SCE&G's motion on December 20, 2017 and requested that the ORS carry out an inspection, audit and examination of SCE&G's revenue requirements to assist the SCPSC in determining whether SCE&G's present schedule of rates is fair and reasonable. Parties who have intervened and continue to intervene in the Request or who filed a letter in support of the Request include the Governor, the state's Office of Attorney General and Speaker of the House of Representatives, the Electric Cooperatives of South Carolina, Santee Cooper, the SCEUC, certain large industrial customers, and several environmental groups. The hearing on the Request has not been scheduled. SCE&G intends to continue vigorously contesting the Request, but cannot give any assurance as to the timing or outcome of this matter.

On September 27, 2017, the scheduled payments under the Toshiba Settlement, exclusive of the payment due in October 2017, were purchased by Citibank for a one-time upfront payment of $1.847 billion (approximately $1.016 billion for SCE&G's 55% share), including amounts related to certain liens that SCE&G was contesting but for which SCE&G may ultimately have been liable. The initial payment was then received from Toshiba on October 2, 2017, as scheduled, in the amount of $150 million ($82.5 million for SCE&G's 55% share). A regulatory liability has been recorded on the consolidated balance sheets to reflect the amount related to the Toshiba Settlement that will be utilized to benefit SCE&G's customers in a manner to be determined by the SCPSC. While this determination is pending, SCE&G has utilized portions of the proceeds to repay maturing commercial paper balances, which short-term borrowings had been incurred primarily for the construction of Unit 2 and Unit 3 prior to the decision to stop their construction. On October 17, 2017, the ORS filed a motion with the SCPSC to amend its earlier Request, in which the ORS asked the SCPSC to consider the most prudent manner by which SCE&G will enable its customers to realize the value of the monetized Toshiba Settlement payments and other payments made by Toshiba towards satisfaction of its obligations to SCE&G. It is possible that the outcome of regulatory or legal proceedings could result in requiring SCE&G's share of these proceeds to be placed in escrow pending their final disposition, or could require these proceeds to be refunded to customers in the near-term or otherwise make these funds unavailable to SCE&G. If any of these circumstances were to arise, it is anticipated that SCE&G may issue commercial paper, draw on its credit facilities or issue long-term debt to fund such requirement. However, such sources may not be available. Any such requirement would significantly harm the Company's and Consolidated SCE&G's results of operations, cash flows and financial condition. In

69

addition, the purchase agreement with Citibank provides that SCE&G and Santee Cooper (each according to its pro rata share) would indemnify Citibank for its losses arising from misrepresentations or covenant defaults under the purchase agreement.

In 2017, SCE&G recorded a pre-tax impairment loss of $1.118 billion related to unrecovered nuclear project costs and other related costs. In the first quarter of 2018, SCE&G recorded an additional pre-tax impairment loss of $3.6 million related to the fair value of nuclear fuel. These impairment losses have had the effect of increasing the Company's and Consolidated SCE&G's debt to total capitalization. If the SCPSC were to rule in favor of the ORS in response to the Request that SCE&G suspend collections from customers of amounts previously authorized under the BLRA, or were other actions of the SCPSC or others taken in order to significantly restrict SCE&G’s access to revenues or impose additional adverse refund obligations on SCE&G, the Company’s and Consolidated SCE&G's assessments regarding the recoverability of all or a portion of the remaining balance of unrecovered Nuclear Project costs would be adversely impacted. Also, the recognition of significant additional impairment losses with respect to unrecovered Nuclear Project or other related costs could further increase the Company’s and Consolidated SCE&G’s debt to total capitalization to a level which may limit their ability to borrow under their commercial paper programs or under their credit facilities and also could constitute a default under these credit facilities. Borrowing costs for long-term debt issuances and access to capital markets could also be negatively impacted.

The ability of SCE&G to recover its costs related to the construction and subsequent abandonment of the Nuclear Project, and a reasonable return on them, through rates will be subject to review and approval by the SCPSC. An application under the abandonment provisions of the BLRA, and the regulatory process contemplated thereby, have never been pursued or legally challenged. As a result, and in light of the contentious nature of the ongoing reviews by and related activities of the South Carolina House Utility Ratepayer Protection Committee, the South Carolina Senate's V.C. Summer Nuclear Project Review Committee and others, and given pending legislation, it is uncertain whether SCE&G will be able to successfully recover the costs of the abandoned units, and a reasonable return on them. Under the BLRA, the SCPSC must consider and rule on a petition within six months. Even so, and although expedited action has been requested by SCE&G, it is unclear when the SCPSC will consider the Joint Petition. In any case, anticipated appeals of any ruling by the SCPSC could be protracted. Further, should the regulatory construct in South Carolina change in such a manner that recovery is sought through other legal proceedings or through regulatory proceedings outside the provisions of the BLRA, such as in a general rate case, other uncertainties may arise, such as those highlighted with respect to the Merger Agreement.

Further downgrades in the credit ratings of SCANA or any of SCANA’s subsidiaries, including SCE&G, could negatively affect our ability to access capital and to operate our businesses, thereby adversely affecting results of operations, cash flows and financial condition.

Various rating agencies currently rate SCE&G’s senior secured debt and the senior unsecured debt of PSNC Energy as investment grade. One rating agency currently rates SCANA’s senior unsecured debt as investment grade, and two rating agencies rate SCANA's senior unsecured debt as below investment grade. In addition, rating agencies maintain ratings on the short-term debt of SCANA, SCE&G, Fuel Company (which ratings are based upon the guarantee of SCE&G) and PSNC Energy. Rating agencies consider qualitative and quantitative factors when assessing SCANA and its rated operating companies’ credit ratings, including regulatory environment, capital structure and the ability to meet liquidity requirements.

In the first quarter of 2017, the rating agencies placed SCANA and SCE&G’s credit ratings on negative outlook or watch status due to adverse developments relating to the WEC bankruptcy. In the third quarter of 2017, two agencies lowered their ratings for SCANA and its rated subsidiaries, citing a decline in the regulatory environment as a principal reason for the downgrades, and both agencies maintained their negative outlook or watch status. On January 3, 2018, after SCANA announced a proposed merger with Dominion Energy, each of the three agencies affirmed or reported no change to their respective credit ratings, and one agency revised its rating outlook for SCANA and its rated operating companies from negative to evolving. However, on January 31, 2018, the South Carolina House of Representatives overwhelmingly approved a bill (H. 4375) that, if enacted, would temporarily repeal rates SCE&G collects under the BLRA. As a result, on February 5, 2018, one agency downgraded its ratings for SCANA and SCE&G, and attributed the downgrade to the action taken by the House of Representatives and the politically charged environment that is expected to weigh heavily on any decisions by the SCPSC related to SCE&G's electric rates. All of the ratings for SCANA, SCE&G and PSNC Energy are either under review for possible downgrade or have a negative or evolving outlook.

Any actions taken by or anticipated to be taken by regulators or legislators that are viewed as adverse, including a change to the BLRA or a requirement that SCE&G make credits to future bills or refunds to customers or any requirement that SCE&G make such credits or refunds in the absence of the merger being consummated, or deterioration of our rated companies’ commonly monitored financial credit metrics and additional adverse developments with respect to the Nuclear Project (including adverse litigation outcomes), could further negatively affect their debt ratings. If these rating agencies were to further lower any of these ratings, borrowing costs on new issuances of long-term debt and commercial paper would

70

increase, which could adversely impact financial results or limit or eliminate refinancing opportunities, and the potential pool of investors and funding sources could decrease. Any further lowering of these ratings could also trigger higher interest costs as well as more stringent collateral requirements on interest rate and commodity hedges and under gas supply agreements and a reduction in the availability of suppliers.

The Company and Consolidated SCE&G are defendants in numerous legal proceedings and the subject of ongoing governmental investigations, examinations and other inquiries stemming from the decision to abandon the Nuclear Project. The outcome of each of these matters is uncertain, and any resolution adverse to the Company and Consolidated SCE&G could adversely affect results of operations, cash flows and financial condition.

Following the Company’s decision to abandon construction of Unit 2 and Unit 3, purported derivative and class action lawsuits have been filed in multiple state circuit courts and federal district court on behalf of customers, shareholders and SCANA (in the case of the derivative shareholder actions), against SCANA, SCE&G, or both, and in certain cases some of their officers and/or directors. The plaintiffs allege various causes of action, including but not limited to waste, breach of fiduciary duty, negligence, unfair trade practices, unjust enrichment, conspiracy, fraud, constructive fraud, misrepresentation and negligent misrepresentation, promissory estoppel, constructive trust, and money had and received, among other causes of action. Plaintiffs generally seek compensatory, consequential and statutory treble damages and such further relief as the court deems just and proper. In addition, certain plaintiffs seek a declaration that SCE&G may not charge its customers to reimburse itself for past and continuing costs of the Nuclear Project. Certain plaintiffs also seek to freeze or appoint a receiver for certain of SCE&G’s assets, namely all money SCE&G has received under the Toshiba payment guaranty and related settlement agreement for the Nuclear Project.

In addition, purported class action lawsuits have been filed on behalf of investors in federal court against SCANA and certain of its current and former executive officers and directors. The plaintiffs allege, among other things, that defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and RICO. In addition, one plaintiff alleges that director defendants violated Section 14(a) of the Exchange Act and SEC Rule 14a-9 by allowing or causing misleading proxy statements to be issued. The plaintiffs in each of these suits seek compensatory and consequential damages and such further relief as the court deems proper.

Lawsuits seeking class action status have also been filed on behalf of investors in the Court of Common Pleas in the Counties of Lexington and Richland, South Carolina, against SCANA, its CEO and directors, Dominion Energy and Sedona. The plaintiffs allege, among other things, that defendants violated their fiduciary duties to shareholders by executing a merger agreement that unfairly deprived plaintiffs of the true value of their SCANA stock, and that Dominion Energy and Sedona aided and abetted these actions. Among other remedies, the plaintiffs seek to enjoin the merger and rescind the Merger Agreement or to have the Merger Agreement amended to provide more favorable terms for plaintiffs, monetary damages, attorneys' fees and such further relief as the court deems proper.

A complaint has been filed by Fairfield County against SCE&G making allegations of breach of contract, fraud, negligent misrepresentation, breach of fiduciary duty, breach of the implied duty of good faith and fair dealing, and unfair trade practices related to SCE&G’s termination of the FILOT agreement. Plaintiff seeks injunctive relief to prevent SCE&G from terminating the FILOT agreement; actual and consequential damages; treble damages; punitive damages; and attorneys’ fees.

The Company has also been served with subpoenas issued by the United States Attorney’s Office for the District of South Carolina and the staff of the SEC's Division of Enforcement seeking documents relating to the Nuclear Project. In addition, the state's Office of Attorney General, the Speaker of the House of Representatives, and the Chair and Vice-Chair of the South Carolina House Utility Ratepayer Protection Committee have requested that SLED conduct a criminal investigation into the handling of the Nuclear Project by SCANA and SCE&G. The Company and Consolidated SCE&G intend to fully cooperate with any such investigations.

On January 26, 2018, the DOR notified SCANA that it was initiating an audit of SCE&G's sales and use tax returns for the periods September 1, 2008 through December 31, 2017. The Company and Consolidated SCE&G understand that the DOR's position is that the exemption for sales and use tax for purchases related to the Nuclear Project should not apply because Unit 2 and Unit 3 will not be placed into service and no electricity will be manufactured for sale. The Company and Consolidated SCE&G intend to vigorously contest the DOR's position.

While the Company and Consolidated SCE&G intend to vigorously contest the lawsuits, claims, and audit positions which have been filed or initiated against them, they cannot predict the timing or outcome of these matters or other claims, allegations or assessments which may arise, including any claims that may be asserted by Santee Cooper, and it is possible that

71

adverse outcomes from some of these matters would not be covered by insurance. A resolution adverse to the Company and Consolidated SCE&G could adversely affect results of operations, cash flows and financial condition.

The Company and Consolidated SCE&G are engaged in activities for which they have claimed, and expect to claim in the future, research and experimentation tax deductions and credits and tax abandonment losses, all of which are the subject of uncertainty and which may be considered controversial by the taxing authorities.  The outcome of those uncertainties could adversely impact cash flows, results of operations and financial condition.

The Company and Consolidated SCE&G have claimed significant research and experimentation tax deductions and credits related to the design and construction activities of Unit 2 and Unit 3. A significant portion of these claims followed the issuance of final IRS regulations in 2014 regarding such treatment with respect to expenditures related to the design and construction of pilot models. The Company and Consolidated SCE&G also expect to claim a significant tax deduction related to the decision to stop construction and to abandon the Nuclear Project in 2017.

These tax claims primarily involve the timing of recognition of tax deductions rather than permanent tax attributes, and their permanent attributes (net), as well as most of the interest accruals required to be recorded with respect to them, had been deferred within regulatory assets. As such, until December 31, 2017 when it was determined to treat these deferrals as impaired, these claims had not had, and were not expected to have in the future, significant direct effects on the Company’s and Consolidated SCE&G’s results of operations.  Nonetheless, the claims have contributed significantly to the Company’s and Consolidated SCE&G’s cash flows by providing a significant source of capital and lessening the level of debt and equity financing that the Company and Consolidated SCE&G have needed to raise in the financial markets. 

The claims made to date are under examination and are considered controversial by the IRS. Tax deductions which are expected to be claimed in connection with the determination to abandon the construction of Unit 2 and Unit 3 may also be considered controversial; therefore, it is also expected that the IRS will examine future tax returns. To the extent that any of these claims are not sustained as ordinary losses on examination or through any subsequent appeal, the Company and Consolidated SCE&G will be required to repay any cash received for tax benefit claims which are ultimately disallowed, along with interest on those amounts. Such amounts could be significant and could adversely affect the Company's and Consolidated SCE&G's liquidity, cash flows, results of operations and financial condition. In certain circumstances, which management considers to be remote, penalties for underpayment of income taxes could also be assessed. Additionally, in such circumstances, the Company and Consolidated SCE&G may need to access the capital markets to fund those tax and interest payments, which could in turn adversely impact their ability to access capital markets for other purposes.

The Company and Consolidated SCE&G are subject to numerous environmental laws and regulations that require significant capital expenditures, can increase our costs of operations and may impact our business plans or expose us to environmental liabilities.

The Company and Consolidated SCE&G are subject to extensive federal, state and local environmental laws and regulations, including those relating to water quality and air emissions (such as reducing NO_X, SO₂, mercury and particulate matter). Some form of regulation is expected at the federal and state levels to impose regulatory requirements specifically directed at reducing GHG emissions from fossil fuel-fired electric generating units. On August 3, 2015, the EPA issued a revised standard for new power plants by re-proposing NSPS under the CAA for emissions of CO₂ from newly constructed fossil fuel-fired units. No new coal-fired plants could be constructed without partial carbon capture and sequestration capabilities. The Company and Consolidated SCE&G are monitoring the final rule, but do not plan to construct new coal-fired units in the foreseeable future. In addition, on August 3, 2015, the EPA issued its final rule on emission guidelines for states to follow in developing plans to address GHG emissions from existing units. On October 10, 2017, the Administrator of the EPA signed a notice proposing to repeal the rule on the grounds that it exceeds the EPA's statutory authority. The EPA is further considering the scope of any potential replacement rule and plans to formally solicit information on systems of emission reduction that are in accord with the EPA's interpretation of its statutory authority. However, a number of bills have been introduced in Congress that seek to require GHG emissions reductions from fossil fuel-fired electric generation facilities, natural gas facilities and other sectors of the economy, although none has yet been enacted. In April 2012, the EPA issued the finalized MATS for power plants that requires reduced emissions from new and existing coal and oil-fired electric utility steam generating facilities. The EPA's rule for cooling water intake structures to meet the best technology available became effective in October 2014, and the EPA also issued a final rule in December 2014 regarding the handling of coal ash and other combustion by-products produced by power plant operations. Furthermore, the EPA finalized new standards under the CWA governing effluent limitation guidelines for electric generating units in September 2015. The rule setting forth these new standards has been stayed administratively, and the EPA has begun a new rulemaking process that could take until 2020 before revisions to the effluent limitation guidelines for electric generating units is complete.

Compliance with these environmental laws and regulations requires us to commit significant resources toward environmental monitoring, installation of pollution control equipment, emissions fees and permitting at our facilities. These expenditures have been significant in the past and are expected to continue or even increase in the future. Changes in compliance requirements, additional regulations and related costs, or more restrictive interpretations by governmental authorities of existing requirements may impose additional costs on us (such as more stringent clean-up of contaminated sites or reduced emission allowances) or require us to incur additional expenditures or curtail some of our cost savings activities (such as the recycling of fly ash and other coal combustion products for beneficial use). Compliance with any GHG emission reduction requirements, including any mandated renewable portfolio standards, also may impose significant costs on us, and the resulting price increases to our customers may lower customer consumption. Such costs of compliance with environmental regulations could negatively impact our businesses and our results of operations and financial position, especially if emissions or discharge limits are reduced or more onerous permitting requirements or additional regulatory requirements are imposed. Additionally, there can be no assurance that a federal tax or fee for carbon emitting generating facilities will not be imposed.

Renewable and/or alternative electric generation portfolio standards may be enacted at the federal or state level. Such renewable energy may not be readily available in our service territories and could be costly to build, finance, acquire, integrate, and/or operate. Resulting increases in the price of electricity to recover the cost of these types of generation, and the costs of their integration to the electric system, could result in lower usage of electricity by our customers. In addition, DER generation at customers’ facilities could result in the loss of sales to those customers. Compliance with potential future portfolio standards could significantly impact our capital expenditures and our results of operations and financial condition. Utility scale solar development companies are currently working in South Carolina to develop projects in SCE&G's service territory. The integration of those resources at high penetration levels may be challenging.

The compliance costs of these environmental laws and regulations are important considerations in the Company's and Consolidated SCE&G's strategic planning and, as a result, significantly affect the decisions to construct, operate, and retire facilities, including generating facilities. In turn, they affect the costs and rates of the Company and Consolidated SCE&G. In effecting compliance with MATS, SCE&G has retired three of its oldest and smallest coal-fired units and converted three others such that they are gas-fired.

Commodity price changes, delays in delivery of commodities, commodity availability and other factors may affect the operating cost, capital expenditures and competitive positions of the Company’s and Consolidated SCE&G’s energy businesses, thereby adversely impacting results of operations, cash flows and financial condition.

Our energy businesses are sensitive to changes in coal, natural gas, uranium and other commodity prices (as well as their transportation costs), availability and deliverability. Any such changes could affect the prices these businesses charge, their operating costs, and the competitive position of their products and services. In addition, the abandonment of the Nuclear Project may heighten the Company's and Consolidated SCE&G's future exposure to volatility in prices of non-nuclear commodities such as natural gas. Consolidated SCE&G is permitted to recover the prudently incurred cost of purchased power and fuel (including transportation) used in electric generation through retail customers’ bills, but purchased power and fuel cost increases affect electric prices and therefore the competitive position of electricity against other energy sources. In addition, when natural gas prices are low enough relative to coal to result in the dispatch of gas-fired electric generation ahead of coal-fired electric generation, higher inventories of coal, with related increased carrying costs, may result. This may adversely affect our results of operations, cash flows and financial condition.

In the case of regulated natural gas operations, costs prudently incurred for purchased gas and pipeline capacity may be recovered through retail customers’ bills. However, in both our regulated and deregulated natural gas markets, increases in gas costs affect total retail prices and therefore the competitive position of gas relative to electricity and other forms of energy. Accordingly, customers able to do so may switch to alternate forms of energy and reduce their usage of gas from the Company and Consolidated SCE&G. Customers on a volumetric rate structure unable to switch to alternate fuels or suppliers may reduce their usage of gas from the Company and Consolidated SCE&G. A regulatory mechanism applies to residential and commercial customers at PSNC Energy to mitigate the earnings impact of an increase or decrease in gas usage.

Certain construction-related commodities, such as copper and aluminum used in our transmission and distribution lines and in our electrical equipment, and steel, concrete and rare earth elements, have experienced significant price fluctuations due to changes in worldwide demand. To operate our air emissions control equipment, we use significant quantities of ammonia, limestone and lime. With EPA-mandated industry-wide compliance requirements for air emissions controls, increased demand for these reagents, combined with the increased demand for low sulfur coal, may result in higher costs for coal and reagents used for compliance purposes.

73

Changing and complex laws and regulations to which the Company and Consolidated SCE&G are subject could adversely affect revenues, increase costs, or curtail activities, thereby adversely impacting results of operations, cash flows and financial condition.

The Company and Consolidated SCE&G operate under the regulatory authority of the United States government and its various regulatory agencies, including the FERC, NRC, SEC, IRS, EPA, the Department of Homeland Security, CFTC and PHMSA. In addition, the Company and Consolidated SCE&G are subject to regulation by the state governments of South Carolina, North Carolina and Georgia via regulatory agencies, state environmental agencies, and state employment commissions. Accordingly, the Company and Consolidated SCE&G must comply with extensive federal, state and local laws and regulations. Such governmental oversight and regulation broadly and materially affect the operation of our businesses. In addition to many other aspects of our businesses, these requirements impact the services mandated or offered to our customers, and the licensing, siting, construction and operation of facilities. They affect our management of safety, the reliability of our electric and natural gas systems, the physical and cyber security of key assets, customer conservation through DSM Programs, information security, the issuance of securities and borrowing of money, financial reporting, interactions among affiliates, the pricing of utility services, the payment of dividends and employment programs and practices. Changes to governmental regulations are continual and potentially costly to effect compliance. Non-compliance with these requirements by third parties, such as our contractors, vendors and agents, may subject the Company and Consolidated SCE&G to operational risks and to liability. We cannot predict the future course of changes in this regulatory environment or the ultimate effect that this changing regulatory environment will have on the Company’s or Consolidated SCE&G’s businesses. Non-compliance with these laws and regulations could result in fines, litigation, loss of licenses or permits, mandated capital expenditures and other adverse business outcomes, as well as reputational damage, which could adversely affect the cash flows, results of operations, and financial condition of the Company and Consolidated SCE&G.

Furthermore, changes in or uncertainty in monetary, fiscal, tax, economic, trade, or regulatory policies of the Federal government may adversely affect the debt and equity markets and the economic climate for the nation, region or particular industries, such as ours or those of our customers. The Company and Consolidated SCE&G also could be adversely impacted by changes in tax policy, or taxes related to the usage of certain fuel types in our businesses or our ownership and/or operation of certain types of generating facilities. Future, unknown regulation of hydraulic fracturing activities also could impact the operations and finances of the Company and Consolidated SCE&G.

The Company and Consolidated SCE&G are subject to extensive rate regulation which could adversely affect operations. Large capital projects (including the abandonment of Unit 2 and Unit 3 as previously described), results of DSM Programs, results of DER programs, and/or increases in operating costs may lead to requests for regulatory relief and any related administrative or legislative action, decision, regulation or law affecting rates, such as rate increases, which may be denied, in whole or part, by rate regulators. Rate increases may also result in reductions in customer usage of electricity or gas, legislative action and lawsuits. Additionally, in 2017 and 2018, several legislative proposals were introduced that have been or are being considered by the South Carolina General Assembly in 2018. In the event certain provisions of these legislative proposals were to become law as proposed, such provisions could adversely impact SCE&G’s rate recovery with respect to the Nuclear Project. Furthermore, there can be no assurance that other legislation which might modify or repeal the BLRA in a manner which would adversely impact SCE&G’s rate recovery, including its reasonable return on costs, with respect to its abandonment of Unit 2 and Unit 3 will not be proposed and passed. Any such action could also result in a failure to consummate the merger.

SCE&G’s electric operations in South Carolina and the Company’s gas distribution operations in South Carolina and North Carolina are regulated by state utilities commissions. In addition, the ability of SCE&G to recover the cost of the Nuclear Project, including abandonment costs, and a reasonable return on those costs, is subject to rate regulation by the SCPSC. Consolidated SCE&G’s generating facilities are subject to extensive regulation and oversight from the NRC and SCPSC. SCE&G's electric transmission system is subject to extensive regulations and oversight from the SCPSC, NERC and FERC. Implementing and maintaining compliance with the NERC's mandatory reliability standards, enforced by FERC, for bulk electric systems could result in higher operating costs and capital expenditures. Non-compliance with these standards could subject SCE&G to substantial monetary penalties. Our gas marketing operations in Georgia are subject to state regulatory oversight and, for a portion of its operations, to rate regulation. There can be no assurance that Georgia’s gas delivery regulatory framework will remain unchanged as market conditions evolve.

Furthermore, Dodd-Frank affects the use and reporting of derivative instruments. The regulations under this legislation provide for substantial additional regulation of over-the-counter and security-based derivative instruments, among other things, and require numerous rule-makings by the CFTC and the SEC to implement, many of which are still pending final action by those federal agencies. The Company and Consolidated SCE&G have determined that they meet the end-user exception to mandatory clearing of swaps under Dodd-Frank. In addition, the Company and Consolidated SCE&G have taken steps to

74

ensure that they are not the party required to report these transactions in real-time (the "reporting party") by transacting solely with swap dealers and major swap participants, when possible, as well as entering into reporting party agreements with counterparties who also are not swap dealers or major swap participants, which establishes that those counterparties are obligated to report the transactions in accordance with applicable Dodd-Frank regulations. While these actions minimize the reporting obligations of the Company, they do not eliminate required recordkeeping for any Dodd-Frank regulated transactions. Despite qualifying for the end-user exception to mandatory clearing and ensuring that neither the Company nor Consolidated SCE&G is the reporting party to a transaction required to be reported in real-time, we cannot predict when the final regulations will be issued or what requirements they will impose.

Our ability to charge customer rates that will allow us to maintain reasonable rates of return is dependent upon regulatory determinations, and there can be no assurance that we will be able to implement rate adjustments when sought.

The Company and Consolidated SCE&G are subject to the reputational risks that may result from a failure to adhere to high standards related to compliance with laws and regulations, ethical conduct, operational effectiveness, customer service and the safety of employees, customers and the public. These risks could adversely affect the valuation of our common stock and the Company’s and Consolidated SCE&G’s access to capital.

The Company and Consolidated SCE&G are committed to comply with all laws and regulations, to assure reliability of provided services, to focus on the safety of employees, customers and the public, to ensure environmental compliance, to maintain the physical and cyber security of their operations and assets, to maintain the privacy of information related to our customers and employees, and to maintain effective communications with the public and key stakeholder groups, particularly during emergencies and times of crisis. Traditional news media and social media can very rapidly convey information, whether factual or not, to large numbers of people, including customers, investors, regulators, legislators and other stakeholders, and the failure to effectively manage timely, accurate communication through these channels could adversely impact our reputation. The Company and Consolidated SCE&G also are committed to operational excellence, to quality customer service, and, through our Code of Conduct and Ethics, to maintain high standards of ethical conduct in our business operations. A failure to meet these commitments, or a perceived failure to meet these commitments, may subject the Company and Consolidated SCE&G not only to fraud, regulatory action, litigation or financial loss, but also to reputational risk that could adversely affect the valuation of SCANA’s stock, adversely affect the Company’s and Consolidated SCE&G’s access to capital, and result in further regulatory oversight. Insurance may not be available or adequate to respond to these events.

A failure of the Company and Consolidated SCE&G to maintain the physical and cyber security of its operations may result in the failure of operations, damage to equipment, or loss of information, and could result in a significant adverse impact to the Company's and Consolidated SCE&G's financial condition, results of operations and cash flows.

The Company and Consolidated SCE&G depend on maintaining the physical and cyber security of their operations and assets.  As much of our business is part of the nation's critical infrastructure, the loss or impairment of the assets associated with that portion of our businesses could have serious adverse impacts on the customers and communities that we serve.  Virtually all of the Company's and Consolidated SCE&G's operations are dependent in some manner upon our cyber systems, which encompass electric and gas operations, nuclear and fossil fuel generating plants, human resource and customer systems and databases, information system networks, and systems containing confidential corporate information. Cyber systems, such as those of the Company and Consolidated SCE&G, are often targets of malicious cyber attacks. A successful physical or cyber attack could lead to outages, failure of operations of all or portions of our businesses, damage to key components and equipment, and exposure of confidential customer, vendor, shareholder, employee, or corporate information. The Company and Consolidated SCE&G may not be readily able to recover from such events. In addition, the failure to secure our operations from such physical and cyber events may cause us reputational damage. Litigation, penalties and claims from a number of parties, including customers, regulators and shareholders, may ensue. Insurance may not be adequate to mitigate the adverse impacts of these events. As a result, the Company's and Consolidated SCE&G's financial condition, results of operations, and cash flows may be adversely affected.

The Company and Consolidated SCE&G are vulnerable to interest rate increases, which would increase our borrowing costs, and we may not have access to capital at favorable rates, if at all. Additionally, potential disruptions in the capital and credit markets may further adversely affect the availability and cost of short-term funds for liquidity requirements and our ability to meet long-term commitments; each could in turn adversely affect our results of operations, cash flows and financial condition.

The Company and Consolidated SCE&G rely on the capital markets, particularly for publicly offered debt and equity, as well as the banking and commercial paper markets, to meet our financial commitments and short-term liquidity needs if internal funds are not available from operations. Changes in interest rates affect the cost of borrowing. The Company’s and

75

Consolidated SCE&G’s business plans, which include significant investments in energy generation and other internal infrastructure projects, reflect the expectation that we will have access to the capital markets on satisfactory terms to fund commitments. Moreover, the ability to maintain short-term liquidity by utilizing commercial paper programs is dependent upon maintaining satisfactory short-term debt ratings and the existence of a market for our commercial paper generally.

The Company’s and Consolidated SCE&G’s ability to draw on our respective bank revolving credit facilities is dependent on the ability of the banks that are parties to the facilities to meet their funding commitments and on our ability to timely renew such facilities. Those banks may not be able to meet their funding commitments to the Company or Consolidated SCE&G if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests from us and other borrowers within a short period of time. Longer-term disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation, reduced alternatives or failures of significant financial institutions could adversely affect our access to liquidity needed for our businesses. Any disruption could require the Company and Consolidated SCE&G to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged. Such measures could include deferring capital expenditures or other discretionary uses of cash or reducing or eliminating dividend payments. Disruptions in capital and credit markets also could result in higher interest rates on debt securities, limited or no access to the commercial paper market, increased costs associated with commercial paper borrowing or limitations on the maturities of commercial paper that can be sold (if at all), increased costs under bank credit facilities and reduced availability thereof, and increased costs for certain variable interest rate debt securities of the Company and Consolidated SCE&G.

Disruptions in the capital markets and their actual or perceived effects on particular businesses and the greater economy also adversely affect the value of the investments held within SCANA’s pension trust. A significant long-term decline in the value of these investments may require us to make or increase contributions to the trust to meet future funding requirements. In addition, a significant decline in the market value of the investments may adversely impact the Company’s and Consolidated SCE&G’s results of operations, cash flows and financial condition, including its shareholders’ equity.

Operating results may be adversely affected by natural disasters, man-made mishaps and abnormal weather.

The Company has delivered less gas and, in deregulated markets, received lower prices for natural gas when weather conditions have been milder than normal, and as a consequence earned less income from those operations. Mild weather in the future could adversely impact the revenues and results of operations and harm the financial condition of the Company and Consolidated SCE&G. Hot or cold weather could result in higher bills for customers and result in higher write-offs of receivables and in a greater number of disconnections for non-payment. In addition, for the Company and Consolidated SCE&G, severe weather can be destructive, causing outages and property damage, adversely affecting operating expenses and revenues.

Natural disasters (such as hurricanes or other significant weather events, electromagnetic events, the 2011 earthquake and tsunami in Japan or fires) or man-made mishaps (such as natural gas transmission pipeline failure, electric utility companies' ash pond failures, and cyber-security failures experienced by many businesses) could have direct significant impacts on the Company and Consolidated SCE&G and on our key contractors and suppliers or could impact us through changes to federal, state or local policies, laws and regulations, and have a significant impact on our financial condition, operating expenses, and cash flows.

The costs of large capital projects, such as the Company’s and Consolidated SCE&G’s construction and environmental compliance programs, are significant, and these projects are subject to a number of risks and uncertainties that may adversely affect the cost, timing and completion of these projects.

The Company’s and Consolidated SCE&G’s businesses are capital intensive and require significant investments in electric generation and in other internal infrastructure projects, including projects for environmental compliance. Achieving the intended benefits of any large construction project is subject to many uncertainties. For instance, the ability to adhere to established budgets and construction schedules may be affected by many variables, such as the regulatory, legal, training and construction processes associated with securing approvals, permits and licenses and necessary amendments to them within projected timeframes, the availability of labor and materials at estimated costs, the availability and cost of financing, and weather. There also may be contractor or supplier performance issues or adverse changes in their creditworthiness and/or financial stability, unforeseen difficulties meeting critical regulatory requirements, contract disputes and litigation, and changes in key contractors or subcontractors. There may be unforeseen engineering problems or unanticipated changes in project design or scope. Our ability to complete construction projects as well as our ability to maintain current operations at reasonable cost could be affected by the availability of key components or commodities, increases in the price of or the unavailability of labor, commodities or other materials, increases in lead times for components, adverse changes in applicable laws and regulations,

76

new or enhanced environmental or regulatory requirements, supply chain failures (whether resulting from the foregoing or other factors), and disruptions in the transportation of components, commodities and fuels. To the extent that, in connection with the construction of a project, delays occur, costs become unrecoverable, or we otherwise become unable to effectively manage and complete the project, our results of operations, cash flows and financial condition, as well as our qualifications for applicable governmental programs, benefits and tax credits may be adversely affected.

A significant portion of Consolidated SCE&G’s generating capacity is derived from nuclear power, the use of which exposes us to regulatory, environmental and business risks. These risks could increase our costs or otherwise constrain our business, thereby adversely impacting our results of operations, cash flows and financial condition.

SCE&G jointly owns and is the operator of Unit 1. Various risks of nuclear generation to which SCE&G is subject include the following:

• The potential harmful effects on the environment and human health resulting from a release of radioactive materials in connection with the operation of nuclear facilities and the storage, handling and disposal of radioactive materials; 

• Limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with our nuclear operations or those of others in the United States;

• The possibility that new laws and regulations could be enacted that could adversely affect the liability structure that currently exists in the United States;

• Uncertainties with respect to procurement of nuclear fuel and suppliers thereof, fabrication of nuclear fuel and related vendors, and the storage of spent nuclear fuel;

• Uncertainties with respect to contingencies if insurance coverage is inadequate;

• Uncertainties with respect to possible future increased regulation of nuclear facilities and nuclear generation, and related costs thereof; and

• Uncertainties with respect to the technological and financial aspects of decommissioning nuclear plants at the end of their operating lives.

The NRC has broad authority under federal law to impose licensing and safety-related requirements for the operation of nuclear generation facilities. In the event of non-compliance, the NRC has the authority to impose fines or shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Revised safety requirements promulgated by the NRC could necessitate capital expenditures at nuclear plants such as ours. In today’s environment, there is a heightened risk of terrorist attack on the nation’s nuclear facilities, which has resulted in increased security costs at our nuclear plant. Although we have no reason to anticipate a serious nuclear incident, a major incident at a nuclear facility anywhere in the world could cause the NRC to limit or prohibit the operation or licensing of any domestic nuclear unit, resulting in costly changes to units in operation and adversely impacting our results of operations, cash flows and financial condition. Furthermore, a major incident at a domestic nuclear facility could result in retrospective premium assessments under our nuclear insurance coverages.

Potential competitive changes may adversely affect our gas and electricity businesses due to the loss of customers, reductions in revenues, or write-down of stranded assets.

The utility industry has been undergoing structural change for a number of years, resulting in increasing competitive pressures on electric and natural gas utility companies. Competition in wholesale power sales via an RTO/ISO is in effect across much of the country, but the Southeastern utilities have retained the traditional bundled, vertically integrated structure. Should an RTO/ISO-market be implemented in the Southeast, potential risks emerge from reliance on volatile wholesale market prices as well as increased costs associated with new transmission and distribution infrastructure.

Some states have also mandated or encouraged unbundled retail competition. Should this occur in South Carolina or North Carolina, increased competition may create greater risks to the stability of utility earnings generally and may in the future reduce earnings from retail electric and natural gas sales. In a deregulated environment, formerly regulated utility companies that are not responsive to a competitive energy marketplace may suffer erosion in market share, revenues and profits as competitors gain access to their customers. In addition, the Company’s and Consolidated SCE&G’s generation assets would be exposed to considerable financial risk in a deregulated electric market. If market prices for electric generation do not produce adequate revenue streams and the enabling legislation or regulatory actions do not provide for recovery of the resulting stranded costs, a write-down in the value of the related assets could be required.

The Company and Consolidated SCE&G are subject to the risk of loss of sales due to the growth of distributed generation especially in the form of renewable power such as solar photovoltaic systems, which systems have undergone a

77

rapid decline in their costs. As a result of federal and state subsidies, potential regulations allowing third-party retail sales, and advances in distributed generation technology, the growth of such distributed generation could be significant in the future. Such growth will lessen Company and Consolidated SCE&G sales and will slow growth, potentially causing higher rates to customers.

The Company and Consolidated SCE&G are subject to risks associated with changes in business and economic climate which could adversely affect revenues, results of operations, cash flows and financial condition and could limit access to capital.

Sales, sales growth and customer usage patterns are dependent upon the economic climate in the service territories of the Company and Consolidated SCE&G, which may be affected by regional, national or even international economic factors. Adverse events, economic or otherwise, may also affect the operations of suppliers and key customers. Such events may result in the loss of suppliers or customers, in higher costs charged by suppliers, in changes to customer usage patterns and in the failure of customers to make timely payments to us. With respect to the Company, such events also could adversely impact the results of operations through the recording of a goodwill or other asset impairment. Also, in connection with the pending merger, some customers or vendors of the Company and Consolidated SCE&G may delay or defer decisions, which could negatively impact the revenues, earnings, cash flows and expenses of the Company and Consolidated SCE&G regardless of whether the merger is completed. The success of local and state governments in attracting new industry to our service territories is important to our sales and growth in sales, as are stable levels of taxation (including property, income or other taxes) which may be affected by local, state, or federal budget deficits, adverse economic climates generally, legislative actions (including tax reform), or regulatory actions. Industrial and commercial customer growth also potentially is affected by the availability of "clean" energy options in our service territory. Budget cutbacks also adversely affect funding levels of federal and state support agencies and non-profit organizations that assist low income customers with bill payments.

In addition, conservation and demand side management efforts and/or technological advances may cause or enable customers to significantly reduce their usage of the Company’s and SCE&G’s products and adversely affect sales, sales growth, and customer usage patterns. For instance, improvements in energy storage technology, if realized, could have dramatic impacts on the viability of and growth in distributed generation.

Factors that generally could affect our ability to access capital include economic conditions and our capital structure. Much of our business is capital intensive, and achievement of our capital plan and long-term growth targets is dependent, at least in part, upon our ability to access capital at rates and on terms that are attractive. If our ability to access capital becomes significantly constrained, our interest costs will likely increase and our financial condition and future results of operations could be adversely impacted.

Problems with operations could cause us to curtail or limit our ability to serve customers or cause us to incur substantial costs, thereby adversely impacting revenues, results of operations, cash flows and financial condition.

Critical processes or systems in the Company’s or Consolidated SCE&G’s operations could become impaired or fail from a variety of causes, such as equipment breakdown, transmission equipment failure, information systems failure or security breach, operator error, natural disasters, and the effects of a pandemic, terrorist attack or cyber attack on our workforce or facilities or on vendors and suppliers necessary to maintain services key to our operations.

In particular, as the operator of power generation facilities, many of which entered service prior to 1985 and may be difficult to maintain, Consolidated SCE&G could incur problems, such as the breakdown or failure of power generation or emission control equipment, transmission equipment, or other equipment or processes which would result in performance below assumed levels of output or efficiency. The integration of a significant amount of distributed generation into our systems may entail additional cycling of our coal-fired generation facilities and may thereby increase the number of unplanned outages at those facilities. In addition, any such breakdown or failure may result in Consolidated SCE&G purchasing emission allowances or replacement power at market rates, if such allowances and replacement power are available at all. These purchases are subject to state regulatory prudency reviews for recovery through rates. If replacement power is not available, such problems could result in interruptions of service (blackout or brownout conditions) in all or part of SCE&G’s territory or elsewhere in the region. Similarly, a natural gas line failure of the Company or Consolidated SCE&G could affect the safety of the public, destroy property, and interrupt our ability to serve customers.

Events such as these could entail substantial repair costs, litigation, fines and penalties, and damage to reputation, each of which could have an adverse effect on the Company’s and Consolidated SCE&G's revenues, results of operations, cash flows, and financial condition. Insurance may not be available or adequate to mitigate the adverse impacts of these events.

78

SCANA’s ability to pay dividends and to make payments on SCANA’s debt securities may be limited by covenants in certain financial instruments (including the Merger Agreement) and by the financial results and condition of its subsidiaries, thereby adversely impacting the valuation of our common stock and our access to capital.

We are a holding company that conducts substantially all of our operations through our subsidiaries. Our assets consist primarily of investments in subsidiaries. Therefore, our ability to meet our obligations for payment of interest and principal on outstanding debt and to pay dividends to shareholders and corporate expenses depends on many factors, including the earnings, cash flows, liquidity and results of operations, historical and anticipated financial condition, capital requirements, market conditions, growth strategy and the availability of growth opportunities of our subsidiaries, and the ability of our subsidiaries, principally Consolidated SCE&G, PSNC Energy and SCANA Energy, to pay dividends or to repay funds to us. Our ability to pay dividends on our common stock may also be limited by existing or future covenants limiting the right of our subsidiaries to pay dividends on their common stock. Further, SCANA has agreed to obtain the consent of Dominion Energy, which consent cannot be unreasonably withheld, prior to making dividend payments to shareholders greater than $0.6125 per share for any quarter while the Merger Agreement is pending.

Any determination to pay dividends to holders of our common stock in the future, as well as the amount of any dividend, are subject to approval by our board of directors, and will depend upon many factors, including those described above and other factors that our board of directors deems relevant. Any significant reduction in our payment of dividends in the future may result in a decline in the value of our common stock. Such a decline in value could limit our ability to raise debt and equity capital.

The use of derivative instruments could result in financial losses and liquidity constraints. The Company and Consolidated SCE&G do not fully hedge against financial market risks or price changes in commodities. This could result in increased costs, thereby resulting in lower margins and adversely affecting results of operations, cash flows and financial condition.

The Company and Consolidated SCE&G use derivative instruments, including futures, forwards, options and swaps, to manage our financial market risks. The Company also uses such derivative instruments to manage certain commodity (i.e., natural gas) market risk. We could be required to provide cash collateral or recognize financial losses on these contracts as a result of volatility in the market values of the underlying commodities and financial contracts or if a counterparty fails to perform under a contract. We could also be required to provide additional cash collateral if credit rating agency downgrades of our debt trigger more stringent requirements.

The Company strives to manage commodity price exposure by establishing risk limits and utilizing various financial instruments (exchange traded and over-the-counter instruments) to hedge physical obligations and reduce price volatility. We do not hedge the entire exposure of our operations from commodity price volatility. To the extent we do not hedge against commodity price volatility or our hedges are not effective, results of operations, cash flows and financial condition may be adversely impacted.

Failure to retain and attract key personnel could adversely affect the Company’s and Consolidated SCE&G’s operations and financial performance, particularly in light of uncertainties related to and resulting from abandonment of the Nuclear Project and the pending merger.

A significant portion of our workforce will be eligible for retirement during the next few years. Uncertainties related to regulatory, legislative and legal proceedings, as well as the proposed merger, also weigh significantly on the employment considerations made by current and prospective employees. We must attract, retain and develop executive officers and other professional, technical and craft employees with the skills and experience necessary to successfully manage, operate and grow our businesses. Competition for these employees is high, and in some cases we must compete for these employees on a regional or national basis. We may be unable to attract and retain these personnel. Further, the Company’s or Consolidated SCE&G’s ability to construct or maintain generation or other assets requires the availability of suitable skilled contractor personnel. We may be unable to obtain appropriate contractor personnel at the times and places needed. Labor disputes with employees or contractors covered by collective bargaining agreements also could adversely affect implementation of our strategic plan and our operational and financial performance. Furthermore, increased medical benefit costs of employees and retirees could adversely affect the results of operations of the Company and Consolidated SCE&G. Medical costs in this country have risen significantly over the past number of years and are expected to continue to increase at unpredictable rates. Such increases, unless satisfactorily managed by the Company and Consolidated SCE&G, could adversely affect results of operations.

The Company and Consolidated SCE&G are subject to the risk that strategic decisions made by us either do not result in a return of or on invested capital or might negatively impact our competitive position, which can adversely impact our results of operations, cash flows, financial condition, and access to capital.

From time to time, the Company and Consolidated SCE&G make strategic decisions that may impact our direction with regard to business opportunities, the services and technologies offered to customers or that are used to serve customers, and the generating plants and other infrastructure that form the basis of much of our business. These strategic decisions may not result in a return of or on our invested capital, and the effects of these strategic decisions may have long-term implications that are not likely to be known to us in the short-term. Changing political climates and public attitudes, including customers' concerns regarding rate increases, such as the current environment relating to proposed recovery of costs, and a reasonable return on those costs, under the abandonment provisions of the BLRA or through other means, may adversely affect the ongoing acceptability of strategic decisions that have been made (and, in some cases, previously supported by legislation or approved by regulators), to the detriment of the Company or Consolidated SCE&G (e.g., revision or repeal of the BLRA). In addition, operating covenants in the Merger Agreement require the consent of Dominion Energy prior to SCANA taking certain actions, which consent cannot be unreasonably withheld, during the pendency of the merger. As a result, the Company and Consolidated SCE&G may be unable to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing or other specified transactions or pursue actions that are not in the ordinary course of business even if such actions would prove beneficial. Further, the Company's and Consolidated SCE&G's management may be focused on completion of the merger, which could lead to the disruption of ongoing business or inconsistencies in service, standards, controls, procedures and policies, any of which could adversely affect the ability of the Company and Consolidated SCE&G to maintain relationships with customers, regulators, vendors and employees, or could otherwise adversely affect their business and financial results, without realizing any of the benefits of having the merger completed. Over time, these strategic decisions or changing attitudes toward such decisions, which could be adverse to the Company’s or Consolidated SCE&G’s interests, may have a negative effect on our results of operations, cash flows and financial condition, as well as limit our ability to access capital.
