1.	Summary of Significant Accounting Policies

Organization

The Company is an energy and energy services provider offering physical delivery and related services for both electricity and natural gas primarily in the south central United States. The Company conducts these activities through two business segments: (i) electric utility and (ii) natural gas midstream operations. The accounts of OGE Energy and its wholly owned and majority owned subsidiaries are included in the consolidated financial statements. All intercompany transactions and balances are eliminated in consolidation. OGE Energy generally uses the equity method of accounting for investments where its ownership interest is between 20% and 50% and has the ability to exercise significant influence.

The electric utility segment generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas. Its operations are conducted through OG&E and are subject to regulation by the OCC, the APSC and the FERC. OG&E was incorporated in 1902 under the laws of the Oklahoma Territory , and is a wholly owned subsidiary of the Company. OG&E is the largest electric utility in Oklahoma and its franchised service territory includes the Fort Smith, Arkansas area. OG&E sold its retail natural gas business in 1928 and is no longer engaged in the natural gas distribution business.

The natural gas midstream operations segment currently represents the Company's investment in Enable, through its wholly owned subsidiary OGE Holdings. Enable is engaged in the business of gathering, processing, transporting and storing natural gas. Enable's natural gas gathering and processing assets are strategically located in four states and serve natural gas production from shale developments in the Anadarko, Arkoma and Ark-La-Tex basins. Enable also owns an emerging crude oil gathering business in the Bakken shale formation, principally located in the Williston basin. Enable's natural gas transportation and storage assets extend from western Oklahoma and the Texas Panhandle to Alabama and from Louisiana to Illinois.

Enable was formed effective May 1, 2013 by OGE Energy, the ArcLight group and CenterPoint Energy, Inc. to own and operate the midstream businesses of OGE Energy and CenterPoint. In the formation transaction, OGE Energy and ArcLight contributed Enogex LLC to Enable and the Company deconsolidated its previously held investment in Enogex Holdings and acquired an equity interest in Enable. The Company determined that its contribution of Enogex LLC to Enable met the requirements of being in substance real estate and was recorded at historical cost. The general partner of Enable is equally controlled by CenterPoint and OGE Energy, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, OGE Energy accounts for its interest in Enable using the equity method of accounting.

Basis of Presentation

The Condensed Consolidated Financial Statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the disclosures are adequate to prevent the information presented from being misleading.

In the opinion of management, all adjustments necessary to fairly present the consolidated financial position of the Company at March 31, 2015 and December 31, 2014 , the results of its operations and cash flows for the three months ended March 31, 2015 and 2014 , have been included and are of a normal recurring nature except as otherwise disclosed.

Due to seasonal fluctuations and other factors , the Company's operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or for any future period. The Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company's 2014 Form 10-K.

Accounting Records

The accounting records of OG&E are maintained in accordance with the Uniform System of Accounts prescribed by the FERC and adopted by the OCC and the APSC. Additionally, OG&E, as a regulated utility, is subject to accounting principles for certain types of rate-regulated activities, which provide that certain actual or anticipated costs that would otherwise be charged to expense can be deferred as regulatory assets, based on the expected recovery from customers in future rates. Likewise, certain actual or anticipated credits that would otherwise reduce expense can be deferred as regulatory liabilities, based on the expected flowback to customers in future rates. Management's expected recovery of deferred costs and flowback of deferred credits generally results from specific decisions by regulators granting such ratemaking treatment.

OG&E records certain actual or anticipated costs and obligations as regulatory assets or liabilities if it is probable, based on regulatory orders or other available evidence, that the cost or obligation will be included in amounts allowable for recovery or refunded in future rates.

The following table is a summary of OG&E's regulatory assets and liabilities at:

Management continuously monitors the future recoverability of regulatory assets. When in management's judgment future recovery becomes impaired, the amount of the regulatory asset is adjusted, as appropriate. If OG&E were required to discontinue the application of accounting principles for certain types of rate-regulated activities for some or all of its operations, it could result in writing off the related regulatory assets, which could have significant financial effects.

Investment in Unconsolidated Affiliate

OGE Energy's investment in Enable is considered to be a variable interest entity because the owners of the equity at risk in this entity have disproportionate voting rights in relation to their obligations to absorb the entity's expected losses or to receive its expected residual returns. However, OGE Energy is not considered the primary beneficiary of Enable since it does not have the power to direct the activities of Enable that are considered most significant to the economic performance of Enable. As discussed above, OGE Energy accounts for the investment in Enable using the equity method of accounting. Under the equity

method, the investment will be adjusted each period for contributions made, distributions received and the Company's share of the investee's comprehensive income. OGE Energy's maximum exposure to loss related to Enable is limited to OGE Energy's equity investment in Enable as presented on the Company's Condensed Consolidated Balance Sheet at March 31, 2015 . The Company evaluates its equity method investment for impairment when events or changes in circumstances indicate there is a loss in value of the investment that is other than a temporary decline.

The Company considers distributions received from Enable which do not exceed cumulative equity in earnings subsequent to the date of investment to be a return on investment which are classified as operating activities in the Condensed Consolidated Statements of Cash Flows. The Company considers distributions received from Enable in excess of cumulative equity in earnings subsequent to the date of investment to be a return of investment which are classified as investing activities in the Condensed Consolidated Statements of Cash Flows.

2.	Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The new guidance was intended to be effective for fiscal years beginning after December 15, 2016. On April 1, 2015, the FASB voted to propose a deferral of the effective date of the new revenue standard by one year, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). The FASB decided, based on its outreach to various stakeholders and the forthcoming exposure drafts, which amend the new revenue standard, that a deferral is necessary to provide adequate time to effectively implement the new revenue standard. The FASB’s proposed deferral is subject to its due process requirement, which includes a period for public comments. The Company is still determining the impact of this standard.

In February 2015, the FASB issued ASU 2015-02, Consolidation. This standard amends the current consolidation guidance. The amendments affect both the variable interest entity and voting interest entity consolidation models. The standard is effective for public reporting entities in fiscal periods beginning after December 15, 2015. At this time, the Company does not believe the new consolidation guidance would impact the entities that are consolidated on the Company's financial statements.

In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest. The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments. The FASB issued the updated guidance as part of its initiative to reduce complexity in accounting standards, as it had received feedback that having different balance sheet presentation requirements for debt issuance costs and debt discount and premium created unnecessary complexity. For public business entities, the amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company will reflect the impacts of this ASU in the first quarter of 2016.


3.	Investment in Unconsolidated Affiliate and Related Party Transactions

On March 14, 2013, OGE Energy entered into a Master Formation Agreement with the ArcLight group and CenterPoint Energy, Inc., pursuant to which OGE Energy, the ArcLight Group and CenterPoint Energy, Inc., agreed to form Enable to own and operate the midstream businesses of OGE Energy and CenterPoint that was initially structured as a private limited partnership. This transaction closed on May 1, 2013.

Pursuant to the Master Formation Agreement, OGE Energy and the ArcLight group indirectly contributed 100 percent of the equity interests in Enogex LLC to Enable . The Company determined that its contribution of Enogex LLC to Enable met the requirements of being in substance real estate and was recorded at historical cost.

On April 16, 2014, Enable completed an initial public offering of 25,000,000 common units resulting in Enable becoming a publicly traded Master Limited Partnership. In connection with Enable’s initial public offering, approximately 61.4 percent of OGE Holdings and CenterPoint’s common units were converted into subordinated units. As a result, following the initial public offering, OGE Holdings owned 42,832,291 common units and 68,150,514 subordinated units of Enable. Holders of subordinated units are not entitled to receive any distribution of available cash until the common units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly distribution from prior quarters. The subordinated units will convert into common units when Enable has paid at least the minimum quarterly distribution for three years or paid at least 150 percent of the minimum quarterly distribution for one year.

On January 26, 2015, Enable announced a quarterly dividend distribution of $0.30875 per unit on its outstanding common and subordinated units, representing an increase of approximately 2.1 percent over the prior quarter distribution. Enable's gross margins are affected by commodity price movements. Based on forward commodity prices, Enable expects to see a decrease in producer activity that will affect its future distribution growth rate. If cash distributions to Enable’s unitholders exceed $0.330625 per unit in any quarter, the general partner will receive increasing percentages, up to 50 percent , of the cash Enable distributes in excess of that amount. OGE Holdings is entitled to 60 percent of those “incentive distributions.” In certain circumstances, the general partner will have the right to reset the minimum quarterly distribution and the target distribution levels at which the incentive distributions receive increasing percentages to higher levels based on Enable’s cash distributions at the time of the exercise of this reset election.

On April 24, 2015, Enable announced a quarterly dividend distribution of $0.31250 per unit on its outstanding common and subordinated units, representing an increase of approximately 1.2 percent over the prior quarter distribution.

At March 31, 2015 , OGE Energy held 26.3 percent of the limited partner interests in Enable.

Distributions received from Enable were $34.3 million and $32.5 million during the three months ended March 31, 2015 and 2014 , respectively.

Related Party Transactions

Operating costs charged and related party transactions between the Company and its affiliate, Enable, since its formation on May 1, 2013 are discussed below. Prior to May 1, 2013, operating costs charged and related party transactions between the Company and Enogex Holdings were eliminated in consolidation. OGE Energy's interest in Enogex Holdings was deconsolidated on May 1, 2013.

On May 1, 2013, OGE Energy and Enable entered into a Services Agreement, Employee Transition Agreement, and other agreements whereby OGE Energy agreed to provide certain support services to Enable such as accounting, legal, risk management and treasury functions for an initial term ending on April 30, 2016. The support services automatically extend year-to-year at the end of the initial term, unless terminated by Enable with at least 90 days’ notice. Enable may terminate the initial support services at any time with 180 days' notice if approved by the board of Enable's general partner. Under these agreements, OGE Energy charged operating costs to Enable of $2.8 million and $6.0 million (which results in a corresponding reduction to OGE Energy's operations and maintenance expense) for the three months ended March 31, 2015 and March 31, 2014 , respectively. OGE Energy charges operating costs to OG&E and Enable based on several factors. Operating costs directly related to OG&E and/or Enable are assigned as such. Operating costs incurred for the benefit of OG&E and Enable are allocated either as overhead based primarily on labor costs or using the "Distrigas" method.

Additionally, OGE Energy agreed to provide seconded employees to Enable to support its operations for an initial term ending on December 31, 2014. In October, 2014, CenterPoint, OGE Energy and Enable agreed to continue the secondment to

Enable of 192 OGE Energy employees that participate in OGE Energy's defined benefit and retirement plans beyond December 31, 2014. OGE Energy billed Enable for reimbursement of $10.0 million and $28.4 million during the three months ended March 31, 2015 and March 31, 2014 , respectively, under the Transitional Seconding Agreement for employment costs.

OGE Energy had accounts receivable from Enable of $6.6 million and $5.6 million as of March 31, 2015 and December 31, 2014 , respectively, for amounts billed for transitional services, including the cost of seconded employees.

Related Party Transactions with Enable

OG&E entered into a new contract with Enable to provide transportation services effective May 1, 2014 which eliminated the natural gas storage services. This transportation agreement grants Enable the responsibility of delivering natural gas to OG&E’s generating facilities and performing an imbalance service. With this imbalance service, in accordance with the cash-out provision of the contract, OG&E purchases gas from Enable when Enable’s deliveries exceed OG&E’s pipeline receipts. Enable purchases gas from OG&E when OG&E’s pipeline receipts exceed Enable’s deliveries. The following table summarizes related party transactions between OG&E and its affiliate, Enable, during the three months ended March 31, 2015 and 2014 .

The formation of Enable was considered a business combination, and CenterPoint Midstream was the acquirer of Enogex Holdings for accounting purposes. Under this method, the fair value of the consideration paid by CenterPoint Midstream for Enogex Holdings is allocated to the assets acquired and liabilities assumed on May 1, 2013 based on their fair value. Enogex Holdings' assets, liabilities and equity have accordingly been adjusted to estimated fair value as of May 1, 2013, resulting in an increase to equity of $2.2 billion . Due to the contribution of Enogex LLC to Enable, meeting the requirements of being in substance real estate and the recording the initial investment at historical cost, the effects of the amortization and depreciation expense

associated with the fair value adjustments on Enable's results of operations have been eliminated in the Company's recording of its equity in earnings of Enable.

OGE Energy recorded equity in earnings of unconsolidated affiliates of $31.7 million and $47.9 million for the three months ended March 31, 2015 and 2014 , respectively. Equity in earnings of unconsolidated affiliates includes OGE Energy's share of Enable earnings adjusted for the amortization of the basis difference of OGE Energy's original investment in Enogex and its underlying equity in net assets of Enable. The basis difference is the result of the initial contribution of Enogex to Enable in May 2013, and subsequent issuances of equity by Enable, including the IPO in April 2014 and the issuance of common units for the acquisition of CenterPoint's 24.95 percent interest in SESH. The basis difference is being amortized over approximately 30 years, the average life of the assets to which the basis difference is attributed. Equity in earnings of unconsolidated affiliates is also adjusted for the elimination of the Enogex Holdings fair value adjustments , as described above.

The difference between the Company's investment in Enable and its underlying equity in the net assets of Enable was $1.0 billion as of March 31, 2015 .

The following table reconciles OGE Energy's equity in earnings of its unconsolidated affiliates for the three months ended March 31, 2015 and 2014 .

4.	Fair Value Measurements

The classification of the Company's fair value measurements requires judgment regarding the degree to which market data is observable or corroborated by observable market data. GAAP establishes a fair value hierarchy that prioritizes the inputs used to measure fair value based on observable and unobservable data. The hierarchy categorizes the inputs into three levels, with the highest priority given to quoted prices in active markets for identical unrestricted assets or liabilities (Level 1) and the lowest priority given to unobservable inputs (Level 3). Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The three levels defined in the fair value hierarchy are as follows:

Level 1 inputs are quoted prices in active markets for identical unrestricted assets or liabilities that are accessible at the measurement date.

Level 2 inputs are inputs other than quoted prices in active markets included within Level 1 that are either directly or indirectly observable at the reporting date for the asset or liability for substantially the full term of the asset or liability. Level 2 inputs include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 inputs are prices or valuation techniques for the asset or liability that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Unobservable inputs reflect the reporting entity's own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk).

The Company had no financial instruments measured at fair value on a recurring basis at March 31, 2015 and December 31, 2014 .

The following table summarizes the fair value and carrying amount of the Company's financial instruments at March 31, 2015 and December 31, 2014 .



	March 31, 2015				December 31, 2014
(In millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-Term Debt
OG&E Senior Notes	$	2,509.8	$	3,000.5	$	2,509.7	$	2,957.7
OG&E Industrial Authority Bonds	135.4		135.4		135.4		135.4
OG&E Tinker Debt	10.2		10.5		10.2		10.3
OGE Energy Senior Notes	100.0		99.9		100.0		99.9

The Company's long-term debt is recorded at the carrying amount. The fair value of the Company's long-term debt is based on quoted market prices and estimates of current rates available for similar issues with similar maturities and is classified as Level 2 in the fair value hierarchy except for the Tinker Debt which fair value was based on calculating the net present value of the monthly payments discounted by the Company's current borrowing rate and is classified as Level 3 in the fair value hierarchy.


5.	Stock-Based Compensation

The following table summarizes the Company's pre-tax compensation expense and related income tax benefit during the three months ended March 31, 2015 and 2014 related to the Company's performance units and restricted stock .

The Company has issued new shares to satisfy restricted stock grants and payouts of earned performance units. During the three months ended March 31, 2015 , there were 80,781 shares of new common stock issued pursuant to the Company's stock incentive plans related to restricted stock grants (net of forfeitures) and payouts of earned performance units. During the three months ended March 31, 2015 , there were 979 shares of restricted stock returned to the Company to satisfy tax liabilities.

The following table summarizes the activity of the Company's stock-based compensation during the three months ended March 31, 2015 .

(A)	Performance units were converted based on a payout ratio of 29 percent of the target number of performance units granted in February 2012 and are included in the 80,781 shares of common stock issued during the three months ended March 31, 2015 as discussed above.


6.	Income Taxes

The Company files consolidated income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. With few exceptions, the Company is no longer subject to U.S. Federal tax examinations by tax authorities for years prior to 2011 or state and local tax examinations by tax authorities for years prior to 2010 . Income taxes are generally allocated to each company in the affiliated group based on its stand-alone taxable income or loss. Federal investment tax credits previously claimed on electric utility property have been deferred and are being amortized to income over the life of the related property. OG&E continues to amortize its Federal investment tax credits on a ratable basis throughout the year. OG&E earns both Federal and Oklahoma state tax credits associated with production from its wind farms and earns Oklahoma state tax credits associated with its investments in electric generating facilities which further reduce the Company's effective tax rate.

As previously reported in the Company's 2014 Form 10-K, OG&E has determined that a portion of certain Oklahoma investment tax credits previously recognized but not yet utilized may not be available for utilization in future years. During the first quarter of 2015, OG&E recorded an additional reserve for this item of $0.2 million ( $0.1 million after the federal tax benefit) related to the same Oklahoma investment tax credits generated in the current year but not yet utilized due to management's determination that it is more likely than not that it will be unable to utilize these credits.


7.	Common Equity

Automatic Dividend Reinvestment and Stock Purchase Plan

The Company issued 89,868 shares of common stock under its Automatic Dividend Reinvestment and Stock Purchase Plan during the three months ended March 31, 2015 and received proceeds of $3.2 million . The Company may, from time to time, issue additional shares under its Automatic Dividend Reinvestment and Stock Purchase Plan to fund capital requirements or working capital needs. At March 31, 2015 , there were 4,901,944 shares of unissued common stock reserved for issuance under the Company's Automatic Dividend Reinvestment and Stock Purchase Plan.

Earnings Per Share

Basic earnings per share is calculated by dividing net income attributable to OGE Energy by the weighted average number of the Company's common shares outstanding during the period. In the calculation of diluted earnings per share, weighted average shares outstanding are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock. Potentially dilutive securities for the Company consist of performance units and restricted stock units. Basic and diluted earnings per share for the Company were calculated as follows:



	Three Months Ended March 31,
(In millions except per share data)	2015		2014
Net Income	$	43.2	$	49.3
Average Common Shares Outstanding
Basic average common shares outstanding	199.5		198.8

8.	Long-Term Debt

At March 31, 2015 , the Company was in compliance with all of its debt agreements.

OG&E Industrial Authority Bonds

OG&E has tax-exempt pollution control bonds with optional redemption provisions that allow the holders to request repayment of the bonds on any business day. The bonds, which can be tendered at the option of the holder during the next 12 months, are as follows:



SERIES			DATE DUE	AMOUNT
				(In millions)
0.05%	-	0.07%	Garfield Industrial Authority, January 1, 2025	$	47.0
0.06%	-	0.07%	Muskogee Industrial Authority, January 1, 2025	32.4
0.05%	-	0.05%	Muskogee Industrial Authority, June 1, 2027	56.0
Total (redeemable during next 12 months)				$	135.4

All of these bonds are subject to an optional tender at the request of the holders, at 100 percent of the principal amount, together with accrued and unpaid interest to the date of purchase. The bond holders, on any business day, can request repayment of the bond by delivering an irrevocable notice to the tender agent stating the principal amount of the bond, payment instructions for the purchase price and the business day the bond is to be purchased. The repayment option may only be exercised by the holder of a bond for the principal amount. When a tender notice has been received by the trustee, a third party remarketing agent for the bonds will attempt to remarket any bonds tendered for purchase. This process occurs once per week. Since the original issuance of these series of bonds in 1995 and 1997, the remarketing agent has successfully remarketed all tendered bonds. If the remarketing agent is unable to remarket any such bonds, OG&E is obligated to repurchase such unremarketed bonds. As OG&E has both the intent and ability to refinance the bonds on a long-term basis and such ability is supported by an ability to consummate the refinancing, the bonds are classified as long-term debt in the Company's Condensed Consolidated Financial Statements. OG&E believes that it has sufficient liquidity to meet these obligations.


9.	Short-Term Debt and Credit Facilities

The Company borrows on a short-term basis, as necessary, by the issuance of commercial paper and by borrowings under its revolving credit agreements. The short-term debt balance was $109.9 million and $98.0 million at March 31, 2015 and December 31, 2014 , respectively. The following table provides information regarding the Company's revolving credit agreements at March 31, 2015 .

(C)	This bank facility is available to back up OG&E's commercial paper borrowings and to provide revolving credit borrowings. This bank facility can also be used as a letter of credit facility.


(D)	Represents the weighted-average interest rate for the outstanding borrowings under the revolving credit agreements, commercial paper borrowings and letters of credit.

The Company's ability to access the commercial paper market could be adversely impacted by a credit ratings downgrade or major market disruptions. Pricing grids associated with the Company's credit facilities could cause annual fees and borrowing rates to increase if an adverse ratings impact occurs. The impact of any future downgrade could include an increase in the costs of the Company's short-term borrowings, but a reduction in the Company's credit ratings by itself would not result in any defaults or accelerations. Any future downgrade could also lead to higher long-term borrowing costs and, if below investment grade, would require the Company to post cash collateral or letters of credit.

OG&E must obtain regulatory approval from the FERC in order to borrow on a short-term basis. OG&E has the necessary regulatory approvals to incur up to $800 million in short-term borrowings at any one time for a two-year period beginning January 1, 2015 and ending December 31, 2016.

12.	Commitments and Contingencies

Except as set forth below, in Note 13 and under "Environmental Laws and Regulations" in Item 2 of Part I and in Item 1 of Part II of this Form 10-Q, the circumstances set forth in Notes 14 and 15 to the Company's Consolidated Financial Statements included in the Company's 2014 Form 10-K appropriately represent, in all material respects, the current status of the Company's material commitments and contingent liabilities.

Environmental Laws and Regulations

Federal Clean Air Act New Source Review Litigation

As previously reported, in July 2008, OG&E received a request for information from the EPA regarding Federal Clean Air Act compliance at OG&E's Muskogee and Sooner generating plants.

On July 8, 2013, the Department of Justice, filed a complaint against OG&E in United States District Court for the Western District of Oklahoma alleging that OG&E did not follow the Federal Clean Air Act procedures for projecting emission increases attributable to eight projects that occurred between 2003 and 2006. The Sierra Club intervened in this proceeding. On September 6, 2013, OG&E filed a Motion to Dismiss the case. On January 15, 2015, U.S. District Judge Timothy DeGuisti dismissed the complaints filed by EPA and Sierra Club. The Court held that it lacked subject matter jurisdiction over Plaintiffs’ claims because Plaintiffs failed to present an actual “case or controversy” as required by Article III of the Constitution. The court also ruled in the alternative that, even if Plaintiffs had presented a case or controversy, it would have nonetheless “decline[d] to exercise jurisdiction.” EPA and the Sierra Club did not file an appeal of the Court’s ruling.

On August 12, 2013, the Sierra Club filed a separate complaint against OG&E in the United States District Court for the Eastern District of Oklahoma alleging that OG&E projects at Muskogee Unit 6 in 2008, were made without obtaining a prevention of significant deterioration permit and that the plant had exceeded emissions limits for opacity and particulate matter. The Sierra Club seeks a permanent injunction preventing OG&E from operating the Muskogee generating plant. On March 4, 2014, the Eastern District dismissed the prevention of significant deterioration permit claim based on the statute of limitations, but allowed the opacity and particulate matter claims to proceed. To obtain the right to appeal this decision, the Sierra Club subsequently withdrew a Notice of Intent to Sue for additional Clean Air Act violations and asked the Eastern District to dismiss its remaining claims with prejudice. On August 27, 2014, the Eastern District granted the Sierra Club's request. The Sierra Club has filed a Notice of Appeal with the 10th Circuit where oral argument was held on March 18, 2015.

the Federal Civil Penalties Inflation Adjustment Act of 1996) provides for civil penalties as much as $37,500 per day for each violation. Due to the uncertain and preliminary nature of this litigation, OG&E cannot provide a range of reasonably possible loss in this case.

Other

In the normal course of business, the Company is confronted with issues or events that may result in a contingent liability. These generally relate to lawsuits or claims made by third parties, including governmental agencies. When appropriate, management consults with legal counsel and other appropriate experts to assess the claim. If, in management's opinion, the Company has incurred a probable loss as set forth by GAAP, an estimate is made of the loss and the appropriate accounting entries are reflected in the Company's Condensed Consolidated Financial Statements. At the present time, based on currently available information, the Company believes that any reasonably possible losses in excess of accrued amounts arising out of pending or threatened lawsuits or claims would not be quantitatively material to its financial statements and would not have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows.


13.	Rate Matters and Regulation

Except as set forth below, the circumstances set forth in Note 15 to the Company's Consolidated Financial Statements included in the Company's 2014 Form 10-K appropriately represent, in all material respects, the current status of the Company's regulatory matters.

Arkansas Regulatory Developments

The State of Arkansas recently enacted two laws related to rate filings. Act 725, among other things, provides a public utility the option, to be exercised concurrently with the filing of a general rate application, to file notice of its intent to exercise its right for an annual formula rate review so as to provide a streamlined review of the utility’s rates to determine if adjustments in rates are justified. If the utility exercises such rights, rates may be adjusted if the earned return rate is 0.5 percent above or below the target return rate. This procedure is expected to reduce regulatory lag in Arkansas. Act 725 additionally allows for evidence to be presented, relative to the calculation of the return on common equity, comparing the requested return on common equity to approved returns on common equity for public utilities delivering similar services with corresponding risks within Arkansas and also in similar regulatory jurisdictions in the same general part of the country.

Act 1000 amends and clarifies existing interim rate requirements to expand the types of expenses that may be recorded and specifically authorize the recovery of allowance for funds used during construction. Act 1000 allows a public utility to file for an interim rate schedule through which it may recover investments and expenses, including allowance for funds used during construction, expended complying with legislative or administrative rules, regulations, or requirements related to the protection of the public, health, safety, or the environment. Rates are implemented at the time of filing of the interim rate schedule, subject to refund.

Pending Regulatory Matters

Environmental Compliance Plan

On August 6, 2014, OG&E filed an application with the OCC for approval of its plan to comply with EPA’s MATS and Regional Haze FIP while serving the best long-term interests of customers in light of future environmental uncertainties. The application seeks approval of the environmental compliance plan and for a recovery mechanism for the associated costs. The environmental compliance plan includes installing dry scrubbers at Sooner Units 1 and 2 and the conversion of Muskogee Units 4 and 5 to natural gas. The application also asks the Commission to predetermine the prudence of replacing OG&E's soon-to-be retired Mustang steam turbines in late 2017 (approximately 460 MW) with 400 MW of new, efficient combustion turbines at the Mustang site in 2018 and 2019 and approval for a recovery mechanism for the associated costs. OG&E estimates the total capital cost associated with its environmental compliance and Mustang modernization plans included in this application to be approximately $1.1 billion . The OCC hearing on OG&E's application began on March 3, 2015 and concluded on April 8, 2015. Multiple parties advocating a variety of positions have intervened in the proceeding. OG&E expects a ruling from the OCC in the second or third quarter of 2015. At this time, OG&E cannot predict the outcome of the proceeding. OG&E plans to file applications in the second quarter of 2015 seeking related approvals from the APSC.

Oklahoma Demand Program Rider Review

In July 2012, OG&E filed an application with the OCC to recover certain costs associated with Demand Programs through the Demand Program Rider, including the lost revenues associated with the SmartHours program. The SmartHours program is designed to incentivize participating customers to reduce on-peak usage or shift usage to off peak hours during the months of May through October, by offering lower rates to those customers in the off peak hours of those months. Lost revenues are created by the difference in the standard rates and the lower incentivized rates. Non SmartHours program customers benefit from the reduction of on-peak usage by SmartHours customers, by the reduction of more costly on-peak generation and the delay in adding new on-peak generation.

In December 2012, the OCC issued an order approving the recovery of costs associated with the Demand Programs, including the lost revenues associated with the SmartHours program, subject to the Oklahoma Public Utility Division staff review.

In March 2014, the Oklahoma Public Utility Division staff began their review of the Demand Program cost, including the lost revenues associated with the SmartHours program. In November 2014, OG&E believed that it had reached an agreement with the Oklahoma Public Utility Division staff on the methodology to be used to calculate lost revenues associated with the SmartHours program and the amount of lost revenue for 2013, which totaled $10.1 million . The agreement also included utilizing the same methodology for calculating lost revenues for 2014, which would result in lost revenues for 2014 of $11.6 million .

In January 2015, OG&E implemented rates that began recovering the 2013 lost revenues, in accordance with the agreement that it believed had been reached with the Oklahoma Public Utility Division staff.

In April 2015, the Oklahoma Public Utility Division staff filed an application, seeking an order from the OCC determining the proper calculation methodology for lost revenues pursuant to OG&E’s Demand Program Rider, primarily affecting the SmartHours program lost revenues. In the application, the Oklahoma Public Utility Division staff recommends the OCC approve the Oklahoma Public Utility Division staff methodology for calculating lost revenues associated with the SmartHours program, which differs from the methodology that OG&E believes it had agreed upon and which would result in recovery of lost revenue for 2013 of only $4.9 million , a reduction of $5.2 million from the amount recorded by OG&E for 2013.

OG&E believes that the methodology agreed to in November 2014, is consistent with the 2012 OCC order, and believes that it is probable that it will recover the $10.1 million of lost revenues associated with 2013, and the $11.6 million associated with 2014. A hearing is scheduled to commence on June 30, 2015.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Introduction

margins are affected by commodity price movements. Based on forward commodity prices, Enable expects to see a decrease in producer activity that will affect its future distribution growth rate. If cash distributions to Enable’s unitholders exceed $0.330625 per unit in any quarter, the general partner will receive increasing percentages, up to 50 percent , of the cash Enable distributes in excess of that amount. OGE Holdings is entitled to 60 percent of those “incentive distributions.”

On April 24, 2015, Enable announced a quarterly dividend distribution of $0.3125 per unit on its outstanding common and subordinated units, representing an increase of approximately 1.2 percent over the prior quarter distribution.

Overview

Company Strategy

The Company's mission, through OG&E and its equity interest in Enable, is to fulfill its critical role in the nation's electric utility and natural gas midstream pipeline infrastructure and meet individual customers' needs for energy and related services focusing on safety, efficiency, reliability, customer service and risk management. The Company's corporate strategy is to continue to maintain its existing business mix and diversified asset position of its regulated electric utility business and interest in a publicly traded midstream company, while providing competitive energy products and services to customers as well as seeking growth opportunities in both businesses. Additionally, the Company wants to achieve a premium valuation of its businesses relative to its peers, grow earnings per share with a stable earnings pattern, create a high performance culture and achieve desired outcomes with target stakeholders. The Company's financial objectives include a long-term annual earnings growth rate for OG&E of three to five percent on a weather-normalized basis, maintaining a strong credit rating as well as targeting dividend increases of approximately 10 percent annually through 2019. The targeted annual dividend increase has been determined after consideration of numerous factors, including the largely retail composition of the Company's shareholder base, the Company's financial position, the Company's growth targets and the composition of the Company's assets and investment opportunities. The Company also relies on cash distributions from its investment in Enable to fund its capital needs and support future dividend growth. The cash distributions from Enable are expected to grow 3 percent to 7 percent in 2015 from the fourth quarter 2014 distribution. The Company believes it can accomplish these financial objectives by, among other things, pursuing multiple avenues to build its business, maintaining a diversified asset position, continuing to develop a wide range of skills to succeed with changes in its industries, providing products and services to customers efficiently, managing risks effectively and maintaining strong regulatory and legislative relationships.

Summary of Operating Results

Three Months Ended March 31, 2015 as Compared to Three Months Ended March 31, 2014

Net income attributable to OGE Energy was $43.2 million , or $0.22 per diluted share, during the three months ended March 31, 2015 as compared to $49.3 million , or $0.25 per diluted share, during the same period in 2014 . The decrease in net income attributable to OGE Energy of $6.1 million , or $0.03 per diluted share, during the three months ended March 31, 2015 as compared to the same period in 2014 was primarily due to:

•

a decrease in net income at OG&E of $3.6 million , or 17.4 percent , or $0.01 per diluted share of the Company's common stock, reflecting a decrease in gross margin related to milder weather during the three months ended March 2015 as compared to the same period in 2014, an increase in interest expense related to the issuance of debt and an increase in depreciation expense due to additional assets being placed into service in 2014. Partially offsetting these items was an increase in gross margin related to an increase in customer growth and lower operations and maintenance expenses from less work done at the power plants ;


•	a decrease in net income attributable to OGE Holdings of $6.6 million , or $0.04 per diluted share of the Company's common stock, due to a decrease in earnings of unconsolidated affiliates primarily due to lower average natural gas prices and lower NGLs prices ; and


•	an increase in net income attributable to OGE Energy of $4.1 million , or $0.02 per diluted share of the Company's common stock, primarily due to gains associated with the deferred compensation plan.

2015 Outlook

The Company estimates 2015 consolidated earnings guidance of $1.76 to $1.89 per average diluted share and distributable cash flow from Enable between $139 million and $142 million are unchanged. See the Company's 2014 Form 10-K for other key factors and assumptions underlying its 2015 earnings guidance.

between the calculated average and 65 is expressed as heating degree days, with each degree of difference equaling one heating degree day. The daily calculations are then totaled for the particular reporting period.

Three Months Ended March 31, 2015 as Compared to Three Months Ended March 31, 2014

OG&E's net income decreased $3.6 million , or 17.4 percent , during the three months ended March 31, 2015 as compared to the same period in 2014 primarily due to higher depreciation and amortization expense and interest expense partially offset by lower other operation and maintenance expense, higher other income and higher gross margin.

Gross Margin

Gross Margin is defined by OG&E as operating revenues less fuel, purchased power and certain transmission expenses. Gross margin is a non-GAAP financial measure because it excludes depreciation and amortization, and other operation and maintenance expenses. Expenses for fuel and purchased power are recovered through fuel adjustment clauses and as a result changes in these expenses are offset in operating revenues with no impact on net income. OG&E believes gross margin provides a more meaningful basis for evaluating its operations across periods than operating revenues because gross margin excludes the revenue effect of fluctuations in these expenses. Gross margin is used internally to measure performance against budget and in reports for management and the Board of Directors. OG&E's definition of gross margin may be different from similar terms used by other companies.

Operating revenues were $480.1 million during the three months ended March 31, 2015 as compared to $560.4 million during the same period in 2014 , a decrease of $80.3 million , or 14.3 percent . Cost of sales were $211.6 million during the three months ended March 31, 2015 as compared to $293.4 million during the same period in 2014 , a decrease of $81.8 million , or 27.9 percent . Gross margin was $268.5 million during the three months ended March 31, 2015 as compared to $267.0 million during the same period in 2014 , an increase of $1.5 million , or 0.6 percent . The below factors contributed to the change in gross margin:



	$ Change
	(In millions)
New customer growth	$	5.3
Price variance (A)	4.9
Wholesale transmission revenue	0.8
Other	0.7
Non-residential demand and related revenues	0.4
Quantity variance (primarily weather)	(10.6		)
Change in gross margin	$	1.5


(A)	Increased primarily due to sales and customer mix.

Cost of sales for OG&E consists of fuel used in electric generation, purchased power and transmission related charges. Fuel expense was $113.8 million during the three months ended March 31, 2015 as compared to $195.1 million during the same period in 2014 , a decrease of $81.3 million , or 41.7 percent , primarily due to a decrease in natural gas prices . Purchased power costs were $86.5 million during the three months ended March 31, 2015 as compared to $89.8 million during the same period in 2014 , a decrease of $3.3 million , or 3.7 percent , primarily due to decreases of $3.3 million in wind purchased power, $1.8 million in cogeneration purchases, $1.0 million in bilateral agreements, and $8.0 million in purchases from the Energy Imbalance Service Market which ceased on February 28, 2014, offset by an increase of $10.8 million in purchases from the SPP, reflecting the impact of OG&E's participation in the SPP Integrated Market, which began on March 1, 2014. Transmission expense is charged to OG&E by the SPP for the utilization of transmission systems owned by other SPP members and is recovered from retail customers through the SPP Cost Tracker in Oklahoma and through the Transmission Cost Rider in Arkansas. Transmission charges were $11.3 million during the three months ended March 31, 2015 as compared to $8.5 million during the same period in 2014 , an increase of $2.8 million , or 32.9 percent , primarily due to higher SPP charges for the base plan projects of other utilities.

The actual cost of fuel used in electric generation and certain purchased power costs are passed through to OG&E's customers through fuel adjustment clauses. The fuel adjustment clauses are subject to periodic review by the OCC, the APSC and the FERC. The OCC, the APSC and the FERC have authority to review the appropriateness of gas transportation charges or other fees OG&E pays to its affiliate, Enable.

Operating Expenses

Other operation and maintenance expense was $114.3 million during the three months ended March 31, 2015 as compared to $117.1 million during the same period in 2014 , a decrease of $2.8 million , or 2.4 percent . The below factors contributed to the change in other operation and maintenance expense:

(B)	Decreased primarily due to lower overtime as a result of less work performed on distribution projects and maintenance at the power plants.


(C)	Increased primarily due to demand side management customer payments which are recovered through a rider.


(D)	Increased primarily due to higher actual medical costs incurred.


(E)	Increased primarily due to annual salary increases.

Depreciation and amortization expense was $73.8 million during the three months ended March 31, 2015 as compared to $64.3 million during the same period in 2014 , an increase of $9.5 million , or 14.8 percent , primarily due to additional assets being placed in service, along with an increase resulting from the amortization of the deferred pension credits regulatory liability which was fully amortized in July 2014.

Additional Information

Other Income. Other income was $1.7 million during the three months ended March 31, 2015 as compared to a loss of $0.3 million during the same period in 2014 , an increase of $2.0 million , primarily due to increased guaranteed flat bill margins.

Interest Expense. Interest expense was $36.8 million during the three months ended March 31, 2015 as compared to $33.9 million during the same period in 2014 , an increase of $2.9 million , or 8.6 percent , primarily due to an increase in interest on long term debt related to a $250 million debt issuance that occurred in March 2014 and a $250 million debt issuance that occurred in December 2014.

Income Tax Expense. Income tax expense was $6.3 million during the three months ended March 31, 2015 as compared to $7.6 million during the same period in 2014 , a decrease of $1.3 million , or 17.1 percent , reflecting lower pretax income.

Three Months Ended March 31, 2015 as Compared to Three Months Ended March 31, 2014

OGE Holding's net income for the three months ended March 31, 2015 as compared to the same period in 2014 decreased $6.6 million , or 22.4 percent , primarily due to a $16.2 million decrease in equity in earnings of Enable. The decrease in equity in earnings of Enable reflected a $18.7 million decrease in the Company's share of Enable's net income. Enable's gathering and processing business segment reported a decrease in operating income primarily from a decrease in gross margin, an increase in operation and maintenance expense, an increase in depreciation and amortization expense and an increase in taxes other than income taxes. Gathering and processing gross margin decreased primarily due to lower average natural gas prices, lower processing margin and lower NGLs prices. Enable's transportation and storage business segment reported a decrease in operating income primarily from a decrease in unrealized gains on natural gas derivatives, a decrease in liquid sales due to lower natural gas liquids prices, a decrease in storage demand fees offset by an increase in off-system transportation sales.

Income Tax Expense. Income tax expense was $8.1 million during the three months ended March 31, 2015 as compared to $18.5 million during the same period in 2014 , a decrease of $10.4 million primarily reflecting lower pretax income and a benefit recognized associated with a remeasurement of deferred taxes related to the Company's investment in Enable.

Off-Balance Sheet Arrangement

There have been no significant changes in the Company's off-balance sheet arrangement from that discussed in the Company's 2014 Form 10-K. The Company has no off-balance sheet arrangements with equity method investments that would affect its liquidity.

Liquidity and Capital Resources

Working Capital

Working capital is defined as the amount by which current assets exceed current liabilities. The Company's working capital requirements are driven generally by changes in accounts receivable, accounts payable, commodity prices, credit extended to, and the timing of collections from customers, the level and timing of spending for maintenance and expansion activity, inventory levels and fuel recoveries.

The balance of Accounts Receivable and Accrued Unbilled Revenues was $222.3 million and $249.9 million at March 31, 2015 and December 31, 2014 , respectively, a decrease of $27.6 million , or 11.0 percent , primarily due to a decrease in billings to OG&E's retail customers reflecting lower usage due to milder weather in March 2015 as compared to December 2014 .

The balance of Fuel Inventories was $82.6 million and $58.5 million at March 31, 2015 and December 31, 2014 , respectively, an increase of $24.1 million , or 41.2 percent , primarily due to higher coal inventory balances at OG&E's coal fired plants resulting from increased deliveries and less coal generation in the three months ended March 2015 as compared to December 2014.

The balance of Fuel Clause Under Recoveries was $27.0 million and $68.3 million at March 31, 2015 and December 31, 2014 , respectively, a decrease of $41.3 million , or 60.5 percent , primarily due to higher amounts billed to OG&E retail customers as compared to the actual cost of fuel and purchased power. The fuel recovery clauses are designed to smooth the impact of fuel price volatility on customers' bills. As a result, OG&E under recovers fuel costs when the actual fuel and purchased power cost recoveries exceed fuel adjustment clause recoveries and over recovers fuel costs when the actual fuel and purchased power costs are below the fuel adjustment clause recoveries. Provisions in the fuel clauses are intended to allow OG&E to amortize under and over recovery balances into future cost recoveries.

The balance of Accounts Payable was $151.9 million and $179.1 million at March 31, 2015 and December 31, 2014 , respectively, a decrease of $27.2 million , or 15.2 percent , primarily due to the timing of vendor payments and a decrease in accruals.

The balance of Accrued Taxes was $24.0 million and $39.7 million at March 31, 2015 and December 31, 2014 , respectively, a decrease of $15.7 million , or 39.5 percent , primarily due to ad valorem tax accruals and payments.

The balance of Accrued Interest was $34.2 million and $43.0 million at March 31, 2015 and December 31, 2014 , respectively, a decrease of $8.8 million , or 20.5 percent , primarily due to the timing of interest payments on long-term debt in 2014 partially offset by additional interest accrued on long-term debt reflecting a $250 million debt issuance in March 2014 and a $250 million debt issuance in December 2014.

The balance of Long-term Debt Due Within One Year was $110.0 million as of March 31, 2015 compared to no balance at December 31, 2014 primarily due to the reclassification of long-term debt that will mature in January 2016.

Net cash provided from (used in) financing activities	(34.9		)	143.8			(178.7		)	*

* Change is greater than 100%.

Operating Activities

The increase of $116.4 million in net cash provided from operating activities during the three months ended March 31, 2015 as compared to the same period in 2014 was primarily due to an increase in cash received from fuel under recoveries and an increase in cash received on accounts receivable from the partners of the jointly owned plants .

Investing Activities

The decrease of $62.7 million , or 36.6 percent , in net cash used in investing activities during the three months ended March 31, 2015 as compared to the same period in 2014 was primarily due to a decrease in transmission projects at OG&E.

Financing Activities

The increase of $178.7 million in net cash used in financing activities during the three months ended March 31, 2015 as compared to the same period in 2014 was primarily due to the issuance of $250 million in long-term debt during the first quarter of 2014 partially offset by an increase in short-term debt.

Future Capital Requirements and Financing Activities

The Company's primary needs for capital are related to acquiring or constructing new facilities and replacing or expanding existing facilities at OG&E. Other working capital requirements are expected to be primarily related to maturing debt, operating lease obligations, fuel clause under and over recoveries and other general corporate purposes. The Company generally meets its cash needs through a combination of cash generated from operations, short-term borrowings (through a combination of bank borrowings and commercial paper ) and permanent financings.

Capital Expenditures

The Company's consolidated estimates of capital expenditures for the years 2015 through 2019 are shown in the following table. These capital expenditures represent the base maintenance capital expenditures (i.e., capital expenditures to maintain and operate the Company's business) plus capital expenditures for known and committed projects. Estimated capital expenditures for Enable are not included in the table below.

(D)

Represent capital costs associated with OG&E’s Environmental Compliance Plan to comply with the EPA’s MATS and Regional Haze rules. More detailed discussion regarding Regional Haze and OG&E’s Environmental Compliance Plan can be found in Note 13 of Notes to Condensed Financial Statements under "Environmental Compliance Plan" in Item 1 of Part I of this Form 10-Q, and under “Environmental Laws and Regulations” within “Management's Discussion and Analysis of Financial Condition and Results of Operations” under Part I, Item 2 of this Form 10-Q.

Additional capital expenditures beyond those identified in the table above, including additional incremental growth opportunities in electric transmission assets , will be evaluated based on their impact upon achieving the Company's financial objectives.

Security Ratings

Access to reasonably priced capital is dependent in part on credit and security ratings. Generally, lower ratings lead to higher financing costs. Pricing grids associated with the Company's credit facilities could cause annual fees and borrowing rates to increase if an adverse ratings impact occurs. The impact of any future downgrade could include an increase in the costs of the Company's short-term borrowings, but a reduction in the Company's credit ratings by itself would not result in any defaults or

accelerations. Any future downgrade could also lead to higher long-term borrowing costs and, if below investment grade, would require the Company to post cash collateral or letters of credit.

A security rating is not a recommendation to buy, sell or hold securities. Such rating may be subject to revision or withdrawal at any time by the credit rating agency and each rating should be evaluated independently of any other rating.

Future Sources of Financing

Management expects that cash generated from operations, proceeds from the issuance of long and short-term debt , distributions from equity method investments and proceeds from the sales of common stock to the public through the Company's Automatic Dividend Reinvestment and Stock Purchase Plan or other offerings and distributions from Enable will be adequate over the next three years to meet anticipated cash needs and to fund future growth opportunities. The Company utilizes short-term borrowings (through a combination of bank borrowings and commercial paper ) to satisfy temporary working capital needs and as an interim source of financing capital expenditures until permanent financing is arranged.

Short-Term Debt and Credit Facilities

Short-term borrowings generally are used to meet working capital requirements. The Company borrows on a short-term basis, as necessary, by the issuance of commercial paper and by borrowings under its revolving credit agreements. At March 31, 2015 , the Company has revolving credit facilities totaling in the aggregate $1,150.0 million . These bank facilities can also be used as letter of credit facilities. The short-term debt balance was $109.9 million and $98.0 million at March 31, 2015 and December 31, 2014 , respectively. The weighted-average interest rate on short-term debt at March 31, 2015 was 0.54 percent . The average balance of short-term debt during the three months ended March 31, 2015 was $125.1 million at a weighted-average interest rate of 0.42 percent . The maximum month-end balance of short-term debt during the three months ended March 31, 2015 was $180.0 million . At March 31, 2015 , there were $1.9 million supporting letters of credit at a weighted-average interest rate of 0.95 percent . At March 31, 2015 , the Company had $1,038.2 million of net available liquidity under its revolving credit agreement s. OG&E has the necessary regulatory approvals to incur up to $800 million in short-term borrowings at any one time for a two-year period beginning January 1, 2015 and ending December 31, 2016. At March 31, 2015 , the Company had no cash and cash equivalents. See Note 9 of Notes to Condensed Consolidated Financial Statements for a discussion of the Company's short-term debt activity.

Quarterly Distributions by Enable

Pursuant to the Enable Agreement, during the first quarter Enable made distributions of approximately $34.3 million to the Company.

Critical Accounting Policies and Estimates

The Condensed Consolidated Financial Statements and Notes to Condensed Consolidated Financial Statements contain information that is pertinent to Management's Discussion and Analysis. In preparing the Condensed Consolidated Financial Statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Changes to these assumptions and estimates could have a material effect on the Company's Condensed Consolidated Financial Statements. However, the Company believes it has taken reasonable, but conservative, positions where assumptions and estimates are used in order to minimize the negative financial impact to the Company that could result if actual results vary from the assumptions and estimates.

In management's opinion, the areas of the Company where the most significant judgment is exercised for all Company segments includes the determination of Pension Plan assumptions, impairment estimates of long-lived assets (including intangible assets) , and income taxes . For the electric utility segment, significant judgment is also exercised in contingency reserves, asset retirement obligations, the allowance for uncollectible accounts and the valuation of regulatory assets and liabilities and unbilled revenues . The selection, application and disclosure of the Company's critical accounting estimates have been discussed with the Company's Audit Committee and are discussed in detail in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in the Company's 2014 Form 10-K.

Commitments and Contingencies

management consults with legal counsel and other appropriate experts to assess the claim. If, in management's opinion, the Company has incurred a probable loss as set forth by GAAP, an estimate is made of the loss and the appropriate accounting entries are reflected in the Company's Condensed Consolidated Financial Statements. At the present time, based on currently available information, the Company believes that any reasonably possible losses in excess of accrued amounts arising out of pending or threatened lawsuits or claims would not be quantitatively material to its financial statements and would not have a material adverse effect on the Company's consolidated financial position, results of operations or cash flows. See Notes 12 and 13 of Notes to Condensed Consolidated Financial Statements in this Form 10-Q for a discussion of the Company's commitments and contingencies.

Environmental Laws and Regulations

The activities of OG&E are subject to numerous, stringent and complex Federal, state and local laws and regulations governing environmental protection. These laws and regulations can change, restrict or otherwise impact OG&E's business activities in many ways including the handling or disposal of waste material, future construction activities to avoid or mitigate harm to threatened or endangered species and requiring the installation and operation of emissions pollution control equipment. Failure to comply with these laws and regulations could result in the assessment of administrative, civil and criminal penalties, the imposition of remedial requirements and the issuance of orders enjoining future operations. OG&E believes that its operations are in substantial compliance with current Federal, state and local environmental standards. These environmental laws and regulations are discussed in detail in Management's Discussion and Analysis of Financial Condition and Results of Operations in the Company's 2014 Form 10-K. Except as set forth below, there have been no material changes to such items.

OG&E expects that environmental expenditures necessary to comply with the environmental laws and regulations discussed below will qualify as part of a pre-approval plan to handle state and Federally mandated environmental upgrades which will be recoverable in Oklahoma from OG&E's retail customers under House Bill 1910, which was enacted into law in May 2005.

Air

Regional Haze Control Measures

The EPA's 2005 regional haze rule is intended to protect visibility in certain national parks and wilderness areas throughout the United States that may be impacted by air pollutant emissions.

On February 18, 2010, Oklahoma submitted its SIP to the EPA, which set forth the state's plan for compliance with the regional haze rule. The SIP was subject to the EPA's review and approval.

The Oklahoma SIP included requirements for reducing emissions of NO _X and SO ₂ from OG&E's seven BART-eligible units at the Seminole, Muskogee and Sooner generating stations. The SIP also included a waiver from BART requirements for all eligible units at the Horseshoe Lake generating station based on air modeling that showed no significant impact on visibility in nearby national parks and wilderness areas. The SIP concluded that BART for reducing NO _X emissions at all of the subject units should be the installation of low NO _X burners with overfire air (flue gas recirculation was also required on two of the units) and set forth associated NO _X emission rates and limits.

On December 28, 2011, the EPA issued a final rule in which it rejected the SO ₂ portion of the Oklahoma SIP and issued a FIP in its place. OG&E and the State of Oklahoma's subsequent appeal of the FIP with the Tenth Circuit of Appeals and the U.S. Supreme Court ended on May 27, 2014 when the Supreme Court denied Petition for Certiorari, upholding the EPA's FIP for SO ₂ . The FIP compliance date is now January 4, 2019.

Federal Clean Air Act New Source Review Litigation

As previously reported, in July 2008, OG&E received a request for information from the EPA regarding Federal Clean Air Act compliance at OG&E's Muskogee and Sooner generating plants.

At this time, OG&E continues to believe that it has acted in compliance with the Federal Clean Air Act, and OG&E expects to vigorously defend against the claims that have been asserted. If OG&E does not prevail in the remainder of the proceedings, the EPA and the Sierra Club could seek to require OG&E to install additional pollution control equipment, including scrubbers, baghouses and selective catalytic reduction systems with capital costs in excess of $1.1 billion and pay fines and significant penalties as a result of the allegations in the notice of violation. Section 113 of the Federal Clean Air Act (along with the Federal Civil Penalties Inflation Adjustment Act of 1996) provides for civil penalties as much as $37,500 per day for each violation. Due to the uncertain and preliminary nature of this litigation, OG&E cannot provide a range of reasonably possible loss in this case.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no significant changes in the market risks affecting the Company from those discussed in the Company's 2014 Form 10-K.

Item 4. Controls and Procedures.

The Company maintains a set of disclosure controls and procedures designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms. In addition, the disclosure controls and procedures ensure that information required to be disclosed is accumulated and communicated to management, including the chief executive officer and chief financial officer, allowing timely decisions regarding required disclosure. As of the end of the period covered by this report, based on an evaluation carried out under the supervision and with the participation of the Company's management, including the chief executive officer and chief financial officer, of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934), the chief executive officer and chief financial officer have concluded that the Company's disclosure controls and procedures are effective.

No change in the Company's internal control over financial reporting has occurred during the Company's most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

PART II. OTHER INFORMATION
