OGE ENERGY CORP.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

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. For a discussion of change in business segments, see Note 12. For periods prior to May 1, 2013, the Company consolidated Enogex Holdings in its Condensed Consolidated Financial Statements. All significant intercompany transactions have been eliminated in consolidation.
Effective May 1, 2013, OGE Energy, the ArcLight group and CenterPoint Energy, Inc., formed Enable Midstream Partners, L.P. 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 of the management rights. Based on the 50/50 management ownership, with neither company having control, effective May 1, 2013, OGE Energy began accounting for its interest in Enable using the equity method of accounting. At March 31, 2014, OGE Energy, through its wholly owned subsidiary OGE Holdings, held 28.5 percent of the limited partner interests in Enable. OGE Energy also owns a 60 percent interest in any incentive distribution rights in Enable. Incentive distribution rights entitle the holder to increasing percentages, up to a maximum of 50 percent, of the cash distributed by Enable in excess of the target quarterly distributions established in connection with Enable’s initial public offering as described below. On April 16, 2014, Enable completed an initial public offering of 28,750,000 common units resulting in Enable becoming a publicly traded Master Limited Partnership. The offering represented approximately 6.9 percent of the limited partner interests and raised approximately $466 million in net proceeds for Enable. As a result of the offering, OGE Holding's ownership was reduced from 28.5 percent to 26.7 percent.
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.
Enable is expected to pay a minimum quarterly distribution of $0.2875 per unit on its outstanding units to the extent it has sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to its general partner and its affiliates, within 45 days after the end of each quarter. Enable will adjust the amount of this distribution for the period from April 16, 2014, the completion of its initial public offering, through June 30, 2014 based on the actual length of the period. 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. As indicated above, 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.
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. 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 consists of the Company's investment in Enable. 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 that commenced initial operations in November 2013. Enable is continuing to construct additional crude oil gathering capacity in this area. Enable's
8

natural gas transportation and storage assets extend from western Oklahoma and the Texas Panhandle to Alabama and from Louisiana to Illinois.
As discussed below, the Company completed a 2-for-1 stock split of the Company's common stock effective July 1, 2013. A ll share and per share amounts within this Form 10-Q reflect the effects of the stock split.

In the opinion of management, all adjustments necessary to fairly present the consolidated financial position of the Company at March 31, 2014 and December 31, 2013, the results of its operations for the three months ended March 31, 2014 and 2013 and the results of its cash flows for the three months ended March 31, 2014 and 2013, 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, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 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 2013 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 refund in future rates.

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, 2014. 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.

Forward Stock Split
On May 16, 2013, the Company's Board of Directors approved a 2-for-1 forward stock split of the Company's common stock, effective July 1, 2013, which entitled each shareholder of record to receive two shares for every one share of Company stock owned by the shareholder. In connection with the stock split, an amendment to the Company's Articles of Incorporation was approved on May 16, 2013 which increased the number of authorized shares of common stock from 225 million to 450 million. A ll share and per share amounts within this Form 10-Q reflect the effects of the stock split.
Reclassifications
Prior to May 1, 2013, the Company reported the results of Enogex Holdings in two separate segments: the natural gas transportation and storage segment, and the natural gas gathering and processing segment. After the deconsolidation, these segments were combined into the natural gas midstream operations segment. The presentation of results for the three months ended March 31, 2013 have been revised to reflect this change. Effective May 1, 2013, the Company deconsolidated its previously held investment in Enogex Holdings and acquired an equity interest in Enable.

2. | Accounting Pronouncement

There were no significant accounting pronouncements issued during the three months ended March 31, 2014 that had or will have a material impact on our consolidated results of operations, financial position or cash flows.

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. Immediately prior to closing, on May 1, 2013, the ArcLight group contributed $107.0 million and OGE Energy contributed $9.1 million to Enogex LLC in order to pay down short-term debt. At March 31, 2014, OGE Energy, through its wholly owned subsidiary OGE Holdings, held 28.5 percent of the limited partner interests in Enable.
The general partner of Enable is equally controlled by CenterPoint and OGE Energy, who each have 50 percent of the management rights. CenterPoint and OGE Energy also own a 40 percent and 60 percent interest, respectively, in any incentive distribution rights to be held by the general partner of Enable following the initial public offering of Enable on April 16, 2014 as described below. Based on the 50/50 management ownership, with neither company having control, effective May 1, 2013, OGE Energy deconsolidated its interest in Enogex Holdings LLC and began accounting for its interest in Enable using the equity method of accounting.
Pursuant to a Registration Rights Agreement dated as of May 1, 2013, OGE Energy and CenterPoint Energy, Inc. agreed to initiate the process for the sale of an equity interest in Enable in an initial public offering. On April 16, 2014, Enable completed an initial public offering of 28,750,000 common units resulting in Enable becoming a publicly traded Master Limited Partnership. The offering represented approximately 6.9 percent of the limited partner interests and raised approximately $466 million in net proceeds for Enable. As a result of the offering, OGE Holding's ownership was reduced from 28.5 percent to 26.7 percent.
On May 1, 2013, OGE Energy, OGE Holdings and Enable entered into a Seconding Agreement. During the term of the Seconding Agreement, OGE Holdings' employees will continue to perform services for Enable and its subsidiaries.
Distributions received from Enable were $32.5 million during the three months ended March 31, 2014.
Related Party Transactions
OGE Energy charged operating costs to Enable of $6.0 million during the three months ended March 31, 2014. 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. The Distrigas method is a three-factor formula that uses an equal weighting of payroll, net operating revenues and gross property, plant and equipment. OGE Energy adopted the Distrigas method in January 1996 as a result of a recommendation by the OCC Staff. OGE Energy believes this method provides a reasonable basis for allocating common expenses.

Summarized Financial Information of Enable
Summarized unaudited financial information for 100 percent of Enable is presented below at March 31, 2014 and for the three months ended March 31, 2014.

Enable concluded that 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 were accordingly adjusted to estimated fair value, resulting in an increase to equity of $2.2 billion. Due to the Company's determination that its contribution of Enogex LLC to Enable met the requirements of being in substance real estate and thus 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 $47.9 million for the three months ended March 31, 2014. Equity in earnings of unconsolidated affiliates includes OGE Energy's 28.5 percent 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, based on historical cost as of May 1, 2013. 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.

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, 2014.
The following table summarizes the fair value and carrying amount of the Company's financial instruments at March 31, 2014 and December 31, 2013.

| March 31, 2014 | December 31, 2013
(In millions) | Carrying Amount | Fair Value | Carrying Amount | Fair Value
Long-Term Debt |  |  |  |
OG&E Senior Notes | $ | 2,403.8 |  | $ | 2,728.0 |  | $ | 2,154.5 |  | $ | 2,405.0 |
OG&E Industrial Authority Bonds | 135.4 |  | 135.4 |  | 135.4 |  | 135.4 |
OG&E Tinker Debt | 10.3 |  | 9.2 |  | 10.3 |  | 9.1 |
OGE Energy Senior Notes | 99.9 |  | 101.7 |  | 99.9 |  | 103.1 |

The Company's long-term debt is valued 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. | Derivative Instruments and Hedging Activities

The Company is exposed to certain risks relating to its ongoing business operations, the most significant being interest rate risk, which the Company may manage through the use of derivative instruments. The Company is also exposed to credit risk in its business operations.
Interest Rate Risk
The Company's exposure to changes in interest rates primarily relates to short-term variable-rate debt and commercial paper. The Company manages its interest rate exposure by monitoring and limiting the effects of market changes in interest rates. The Company may utilize interest rate derivatives to alter interest rate exposure in an attempt to reduce the effects of these changes. Interest rate derivatives are used solely to modify interest rate exposure and not to modify the overall leverage of the debt portfolio.
15

Credit Risk
The Company is exposed to certain credit risks relating to its ongoing business operations. Credit risk includes the risk that counterparties that owe the Company money or energy will breach their obligations. If the counterparties to these arrangements fail to perform, the Company may be forced to enter into alternative arrangements. In that event, the Company's financial results could be adversely affected and the Company could incur losses.
Cash Flow Hedges
For derivatives that are designated and qualify as a cash flow hedge, the effective portion of the change in fair value of the derivative instrument is reported as a component of Accumulated Other Comprehensive Income (Loss) and recognized into earnings in the same period during which the hedged transaction affects earnings. The ineffective portion of a derivative's change in fair value or hedge components excluded from the assessment of effectiveness is recognized currently in earnings. The Company measures the ineffectiveness of commodity cash flow hedges using the change in fair value method whereby the change in the expected future cash flows designated as the hedge transaction are compared to the change in fair value of the hedging instrument. Forecasted transactions, which are designated as the hedged transaction in a cash flow hedge, are regularly evaluated to assess whether they continue to be probable of occurring. If the forecasted transactions are no longer probable of occurring, hedge accounting will cease on a prospective basis and all future changes in the fair value of the derivative will be recognized directly in earnings.
The Company previously designated as cash flow hedges derivatives for OGE Holdings' NGLs volumes and corresponding keep-whole natural gas resulting from its natural gas processing contracts (processing hedges) and natural gas positions resulting from its natural gas gathering and processing operations and natural gas transportation and storage operations (operational gas hedges). The Company also previously designated as cash flow hedges certain derivatives for certain natural gas storage inventory positions. Due to the deconsolidation of Enogex LLC effective May 1, 2013, the Company had no material instruments designated as cash flow hedges at March 31, 2014.
Income Statement Presentation Related to Derivative Instruments
The following tables present the effect of derivative instruments on the Company's Condensed Consolidated Statement of Income for the three months ended March 31, 2013.

7. | 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 2010 or state and local tax examinations by tax authorities for years prior to 2009. 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 2013 Form 10-K, in January 2013, OG&E 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 2014, OG&E recorded an additional reserve for this item of $0.3 million ($0.2 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.

8. | Common Equity

Forward Stock Split
On May 16, 2013, the Company's Board of Directors approved a 2-for-1 forward stock split of the Company's common stock, effective July 1, 2013, which entitled each shareholder of record to receive two shares for every one share of Company stock owned by the shareholder. In connection with the stock split, an amendment to the Company's Articles of Incorporation was approved on May 16, 2013 which increased the number of authorized shares of common stock from 225 million to 450 million. A ll share and per share amounts within this Form 10-Q reflect the effects of the stock split.
Automatic Dividend Reinvestment and Stock Purchase Plan
The Company issued 98,476 shares of common stock under its Automatic Dividend Reinvestment and Stock Purchase Plan during the three months ended March 31, 2014 and received proceeds of $3.4 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, 2014, there were 3,747,027 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. Basic and diluted earnings per share for the Company were calculated as follows:

9. | Long-Term Debt

At March 31, 2014, 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:

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.
Issuance of Long-Term Debt
On March 25, 2014, OG&E completed the issuance of $250 million of 4.55% senior notes due March 15, 2044. The proceeds from the issuance were added to OG&E's general funds and were used to repay short-term debt, fund capital expenditures and general corporate expenses, and utilized for working capital purposes. OG&E expects to issue additional long-term debt from time to time when market conditions are favorable and when the need arises.

10. | 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 $377.8 million and $439.6 million at March 31, 2014 and December 31, 2013, respectively. The following table provides information regarding the Company's revolving credit agreements at March 31, 2014.

| Aggregate | Amount | Weighted-Average |  |
Entity | Commitment | Outstanding (A) | Interest Rate |  | Maturity
| (In millions) |  |  |
OGE Energy (B) | $ | 750.0 |  | $ | 377.8 |  | 0.28 | % | (D) | December 13, 2017
OG&E (C) | 400.0 |  | 2.0 |  | 0.47 | % | (D) | December 13, 2017
Total | $ | 1,150.0 |  | $ | 379.8 |  | 0.28 | % |  |

(A) | Includes direct borrowings under the revolving credit agreements, commercial paper borrowings and letters of credit at March 31, 2014.

(B) | This bank facility is available to back up OGE Energy's commercial paper borrowings and to provide revolving credit borrowings. This bank facility can also be used as a letter of credit facility.

(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 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, 2013 and ending December 31, 2014.

12. | Report of Business Segments

The Company reports its operations in two business segments: (i) the electric utility segment, which is engaged in the generation, transmission, distribution and sale of electric energy, and (ii) natural gas midstream operations segment.
The natural gas midstream operations segment reflects the Company's equity interest in Enable since its formation on May 1, 2013. Prior to May 1, 2013, the Company reported the results of Enogex Holdings in two separate segments: the natural gas transportation and storage segment, and the natural gas gathering and processing segment. After the deconsolidation, these segments were combined into the natural gas midstream operations segment. The presentation of results for the three months ended March 31, 2013 have been revised to reflect this change. Equity in earnings of unconsolidated affiliates in the natural gas midstream operations segment includes OGE Energy's equity interest in Enable since May 1, 2013. Other than equity in earnings of unconsolidated affiliates, all amounts for the natural gas midstream operations segment represent the operation results of Enogex Holdings through April 30, 2013. Investment in unconsolidated affiliates in the natural gas midstream operations segment represents OGE Energy's investment in Enable at March 31, 2014.
Other Operations primarily includes the operations of the holding company.
Intersegment revenues are recorded at prices comparable to those of unaffiliated customers and are affected by regulatory considerations.
In reviewing its segment operating results, the Company focuses on operating income and equity in earnings of unconsolidated affiliates as measures of segment profit and loss, and, therefore, has presented this information below. The following tables summarize the results of the Company's business segments during the three months ended March 31, 2014 and 2013.

13. | Commitments and Contingencies

Except as set forth below, in Note 14 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 16 and 17 to the Company's Consolidated Financial Statements included in the Company's 2013 Form 10-K appropriately represent, in all material respects, the current status of the Company's material commitments and contingent liabilities.
OG&E Minimum Fuel Purchase Commitments
OG&E has coal contracts for purchases through December 2016. Also, as previously reported, OG&E had entered into multiple-month term natural gas contracts for 31.5 percent of its 2014 annual forecasted natural gas requirements. In March 2014, through a request for proposal, OG&E entered into various multiple-month term natural gas contracts for 42.6 percent of its remaining forecasted 2014 natural gas requirements. Additional gas supplies to fulfill OG&E's remaining 2014 natural gas requirements will be acquired through additional requests for proposal in mid-2014, along with monthly and daily purchases, all of which are expected to be made at market prices.
Enable Gas Transportation and Storage Agreement
OG&E contracts with Enable for gas transportation and storage services. The stated term of this contract expired April 30, 2009, but remained in effect from year-to-year thereafter. On January 31, 2014, in anticipation of entering into a new, five-year contract, OG&E provided written notice of termination of the contract, effective April 30, 2014. On March 17, 2014, OG&E entered into a new contract effective May 1, 2014 and expiring April 30, 2019.
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. In recent years, the EPA has issued similar requests to numerous other electric utilities seeking to determine whether various maintenance, repair and replacement projects should have required permits under the Federal Clean Air Act's new source review process. In January 2012, OG&E received a supplemental request for an update of the previously provided information and for some additional information not previously requested. On May 1, 2012, OG&E responded to the EPA's supplemental request for information. On April 26, 2011, the EPA issued a notice of violation alleging that 13 projects occurred at OG&E's Muskogee and Sooner generating plants between 1993 and 2006 without the required new source review permits. The notice of violation also alleges that OG&E's visible emissions at its Muskogee and Sooner generating plants are not in accordance with applicable new source performance standards.
22

In March 2013, the DOJ informed OG&E that it was prepared to initiate enforcement litigation concerning the matters identified in the notice of violation. OG&E subsequently met with EPA and DOJ representatives regarding the notice of violation and proposals for resolving the matter without litigation. On July 8, 2013, the United States, at the request of the EPA, filed a complaint for declaratory relief against OG&E in United States District Court for the Western District of Oklahoma (Case No. CIV-13-690-D) 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. This complaint seeks to have OG&E submit a new assessment of whether the projects were likely to result in a significant emissions increase. The Sierra Club has intervened in this proceeding and has asserted claims for declaratory relief that are similar to those requested by the United States. OG&E expects to vigorously defend against these claims, but OG&E cannot predict the outcome of such litigation.
On August 12, 2013, the Sierra Club filed a complaint against OG&E in the United States District Court for the Eastern District of Oklahoma (Case No. 13-CV-00356) alleging that OG&E modifications made at Unit 6 of the Muskogee generating plant in 2008 were made without obtaining a prevention of significant deterioration permit and that the plant has 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 United States District Court for the Eastern District of Oklahoma dismissed the prevention of significant deterioration permit claim because it was filed after the statute of limitations expired, but the court allowed the opacity and particulate matter claims to proceed. At this time, OG&E continues to believe that it has acted in compliance with the Federal Clean Air Act.
If OG&E does not prevail in these proceedings and if a new assessment of the projects were to conclude that they caused a significant emissions increase, 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 $1.0 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. The cost of any required pollution control equipment could also be significant. OG&E cannot predict at this time whether it will be legally required to incur any of these costs.
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, except as otherwise stated above, in Note 13 below, under "Environmental Laws and Regulations" in Item 2 of Part 1 and in Item 1 of Part II of this Form 10-Q, in Notes 15 and 16 of Notes to Consolidated Financial Statements and in Item 3 of Part I of the Company's 2013 Form 10-K, 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.

14. | Rate Matters and Regulation

Except as set forth below, the circumstances set forth in Note 16 to the Company's Consolidated Financial Statements included in the Company's 2013 Form 10-K appropriately represent, in all material respects, the current status of the Company's regulatory matters.
Completed Regulatory Matters
Market-Based Rate Authority
On June 29, 2012, OG&E filed its triennial market power update with the FERC to retain its market-based rate authorization in the SPP's energy imbalance service market but to surrender its market-based rate authorization for any market-based rates sales outside of the SPP's energy imbalance service market. On May 2, 2013, the FERC issued an order accepting OG&E's June 2012 triennial market power update.
On December 30, 2013, OG&E submitted to the FERC a market-based rate change in status filing and a revised market-based rate tariff. The revised tariff will authorize OG&E to (i) sell electric energy and capacity at market-based rates without geographic restriction, and (ii) sell ancillary services in the SPP and Midcontinent Independent System Operator, Inc. markets. The primary goal of this filing was to implement the market-based rate authority OG&E needs to fully participate in SPP’s Integrated
23

Marketplace. On February 28, 2014, FERC issued a letter order accepting OG&E’s market-based rate filing and tariff effective March 1, 2014. FERC found that OG&E passed the market power screens and satisfied requirements related to horizontal market power and vertical market power.
Section 206 Complaint
On November 26, 2013, Arkansas Electric Cooperative Corporation filed a complaint at the FERC against OG&E, arguing that the wholesale formula rate contract between OG&E and Arkansas Electric Cooperative Corporation (formerly between OG&E and Arkansas Valley Electric Cooperative) is unjust and unreasonable with respect to several items. OG&E and Arkansas Electric Cooperative Corporation agreed to terms of a settlement and filed the offer of settlement with FERC on February 24, 2014. On April 17, 2014, OG&E received a FERC order accepting the settlement agreement and terminating the Arkansas Electric Cooperative Corporation complaint docket. OG&E believes the reduction in revenue will be approximately $1.0 million per year for the term of the agreement, which ends June 30, 2015.
Pending Regulatory Matters
Fuel Adjustment Clause Review for Calendar Year 2012
The OCC routinely reviews the costs recovered from customers through OG&E's fuel adjustment clause. On July 31, 2013, the OCC Staff filed an application to review OG&E's fuel adjustment clause for calendar year 2012, including the prudence of OG&E's electric generation, purchased power and fuel procurement costs. OG&E filed the necessary information and documents needed to satisfy the OCC's minimum filing requirement rules on October 9, 2013. On April 24, 2014, the OCC administrative law judge at the hearing, on the merits, recommended that the OCC find for the calendar year 2012 OG&E's electric generation, purchased power and fuel procurement processes and costs were prudent.
Energy Efficiency Program Filing
On February 14, 2014, OG&E filed an application with the APSC requesting approval of interim modifications to approved Energy Efficiency Programs, new tariff revisions and the waiver of certain provisions of the Commission’s Rules for Conservation and Energy Efficiency Programs.
Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
Introduction
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. For a discussion of change in business segments, see Note 12 of Notes to Condensed Consolidated Financial Statements. For periods prior to May 1, 2013, the Company consolidated Enogex Holdings in its Condensed Consolidated Financial Statements.
Effective May 1, 2013, OGE Energy, the ArcLight group and CenterPoint Energy, Inc., formed Enable Midstream Partners, L.P. 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 of the management rights. Based on the 50/50 management ownership, with neither company having control, effective May 1, 2013, OGE Energy began accounting for its interest in Enable using the equity method of accounting. At March 31, 2014, OGE Energy, through its wholly owned subsidiary OGE Holdings, held 28.5 percent of the limited partner interests in Enable. OGE Energy also owns a 60 percent interest in any incentive distribution rights in Enable. Incentive distribution rights entitle the holder to increasing percentages, up to a maximum of 50 percent, of the cash distributed by Enable in excess of the target quarterly distributions established in connection with Enable’s initial public offering as described below. On April 16, 2014, Enable completed an initial public offering of 28,750,000 common units resulting in Enable becoming a publicly traded Master Limited Partnership. The offering represented approximately 6.9 percent of the limited partner interests and raised approximately $466 million in net proceeds for Enable. As a result of the offering, OGE Holding's ownership was reduced from 28.5 percent to 26.7 percent.
24

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.
Enable is expected to pay a minimum quarterly distribution of $0.2875 per unit on its outstanding units to the extent it has sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to its general partner and its affiliates, within 45 days after the end of each quarter. Enable will adjust the amount of this distribution for the period from April 16, 2014, the completion of its initial public offering, through June 30, 2014 based on the actual length of the period. 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. As indicated above, OGE Holdings is entitled to 60 percent of those “incentive distributions.”
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. 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.
OG&E began participating in the SPP Integrated Marketplace effective March 1, 2014. The SPP Integrated Marketplace replaced the SPP Energy Imbalance Services market. As part of the Integrated Marketplace, the SPP assumed balancing authority responsibilities for its market participants. The SPP Integrated Marketplace functions as a centralized dispatch, where market participants, including OG&E, submit offers to sell power to the SPP from their resources and bid to purchase power from the SPP for their customers. The SPP Integrated Marketplace is intended to allow the SPP to optimize supply offers and demand bids based upon reliability and economic considerations, and determine which generating units will run at any given time for maximum cost-effectiveness. As a result, OG&E's generating units may produce output that differs from OG&E's customer load requirements. Net fuel and purchased power costs will be recovered through fuel adjustment clauses.
The natural gas midstream operations segment consists of the Company's investment in Enable. 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 that commenced initial operations in November 2013. Enable is continuing to construct additional crude oil gathering capacity in this area. Enable's natural gas transportation and storage assets extend from western Oklahoma and the Texas Panhandle to Alabama and from Louisiana to Illinois.
As discussed in Note 1 of Notes to Condensed Consolidated Financial Statements, the Company completed a 2-for-1 stock split of the Company's common stock effective July 1, 2013. A ll share and per share amounts within this Form 10-Q reflect the effects of the stock split.
Overview
Company Strategy
The Company's mission is to fulfill its critical role in the nation's electric utility and natural gas midstream pipeline infrastructure, through its equity interest in Enable, 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 unregulated natural gas midstream business, through its equity interest in Enable, while providing competitive energy products and services to customers primarily in the south central United States 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 of five to seven percent on a weather-normalized basis, maintaining a strong credit rating as well as increasing the dividend to meet the Company's dividend payout objectives. The Company's target payout ratio is to pay out dividends of approximately 60 percent of its normalized earnings on an annual basis. The target payout ratio 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, the composition of the Company's assets and investment opportunities. 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
25

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, 2014 as Compared to Three Months Ended March 31, 2013
Net income attributable to OGE Energy was $49.3 million, or $0.25 per diluted share, during the three months ended March 31, 2014 as compared to $23.1 million, or $0.12 per diluted share, during the same period in 2013. The increase in net income attributable to OGE Energy of $26.2 million, or $0.13 per diluted share, during the three months ended March 31, 2014 as compared to the same period in 2013 was primarily due to:

• | an increase in net income at OG&E of $7.7 million, or 59.2 percent, or $0.03 per diluted share of the Company's common stock, primarily due to an increase in gross margin as a result of higher transmission revenue along with higher sales due to colder weather, which was partially offset by higher expenses related to ongoing maintenance at the power plants;

• | an increase in net income attributable to OGE Holdings of $17.1 million, or $0.09 per diluted share of the Company's common stock, due to the accretive effect to OGE Holdings of Enable; and

• | a decrease in net losses attributable to OGE Energy of $1.4 million, or $0.01 per diluted share of the Company's common stock, primarily due to transaction expenses related to the formation of Enable during 2013 and a decrease in deferred compensation expense.

2014 Outlook
The Company's 2014 consolidated earnings guidance remained unchanged between approximately $388 million and $411 million of net income, or $1.94 to $2.06 per average diluted share and assumes approximately 200 million average share outstanding. This guidance assumes normal weather for the remainder of the year and includes the impact from the Company's equity interest in Enable. See the Company's 2013 Form 10-K for other key factors and assumptions underlying its 2014 earnings guidance.
Results of Operations
The following discussion and analysis presents factors that affected the Company's consolidated results of operations for the three months ended March 31, 2014 as compared to the same period in 2013 and the Company's consolidated financial position at March 31, 2014. Due to seasonal fluctuations and other factors, the Company's operating results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any future period. The following information should be read in conjunction with the Condensed Consolidated Financial Statements and Notes thereto. Known trends and contingencies of a material nature are discussed to the extent considered relevant.

Three Months Ended March 31, 2014 as Compared to Three Months Ended March 31, 2013
OG&E's operating income increased $8.9 million, or 16.8 percent, during the three months ended March 31, 2014 as compared to the same period in 2013 primarily due to higher gross margin partially offset by higher other operation and maintenance expense and higher depreciation and amortization.
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 $560.4 million during the three months ended March 31, 2014 as compared to $455.5 million during the same period in 2013, an increase of $104.9 million, or 23.0 percent. Cost of sales were $293.4 million during the three months ended March 31, 2014 as compared to $213.0 million during the same period in 2013, an increase of $80.4 million, or 37.7 percent. Gross margin was $267.0 million during the three months ended March 31, 2014 as compared to $242.5 million during the same period in 2013, an increase of $24.5 million, or 10.1 percent. The below factors contributed to the change in gross margin:

| $ Change
| (In millions)
Wholesale transmission revenue (A) | $ | 11.7 |
Quantity variance (primarily weather) | 10.0 |
New customer growth | 2.2 |
Non-residential demand and related revenues | 1.1 |
Other | 0.5 |
Price variance (B) | (1.0 | )
Change in gross margin | $ | 24.5 |

(A) | Increased primarily due to higher investments related to certain FERC approved transmission projects included in formula rates.

(B) | Decreased 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 $195.1 million during the three months ended March 31, 2014 as compared to $146.4 million during the same period in 2013, an increase of $48.7 million, or 33.3 percent, primarily due to higher natural gas prices. Purchased power costs were $89.8 million during the three months ended March 31, 2014 as compared to $60.1 million during the same period in 2013, an increase of $29.7 million, or 49.4 percent, primarily due to an increase 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 $8.5 million during the three months ended March 31, 2014 as compared to $6.5 million during the same period in 2013, an increase of $2.0 million, or 30.8 percent, primarily due to higher SPP charges for the base plan projects of other utilities.
Variances in the actual cost of fuel used in electric generation and certain purchased power costs, as compared to the fuel component included in the cost-of-service for ratemaking, 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 $117.1 million during the three months ended March 31, 2014 as compared to $105.1 million during the same period in 2013, an increase of $12.0 million, or 11.4 percent. The below factors contributed to the change in other operation and maintenance expense:

| $ Change
| (In millions)
Ongoing maintenance at power plants (A) | $ | 7.4 |
Corporate overhead and allocations | 2.5 |
Contract professional services (primarily marketing services) | 1.6 |
Capitalized labor | 1.6 |
Other | 0.8 |
Vegetation management | (1.9 | )
Change in other operation and maintenance expense | $ | 12.0 |

(A) | Increased as a result of routine maintenance typically performed in the first quarter that was delayed until the fourth quarter of 2013.

Depreciation and amortization expense was $64.3 million during the three months ended March 31, 2014 as compared to $61.3 million during the same period in 2013, an increase of $3.0 million, or 4.9 percent, primarily due to additional assets being placed in service throughout 2013. This was partially offset by a decrease in the amortization of the pension regulatory asset which was fully amortized in July 2013.
Additional Information
Other Income. Other income was a net loss of $0.3 million during the three months ended March 31, 2014 as compared to a net gain of $2.7 million during the same period in 2013, a decrease of $3.0 million, primarily due to a decreased margin of $2.7 million recognized in the guaranteed flat bill program during 2014 as a result of higher usage due to cooler weather.
Interest Expense. Interest expense was $33.9 million during the three months ended March 31, 2014 as compared to $31.4 million during the same period in 2013, an increase of $2.5 million, or 8.0 percent, primarily due to a $2.6 million increase in interest on long term debt related to a $250 million debt issuance that occurred in May 2013 and a $250 million debt issuance that occurred in March 2014.
Income Tax Expense. Income tax expense was $7.6 million during the three months ended March 31, 2014 as compared to $11.9 million during the same period in 2013, a decrease of $4.3 million or 36.1 percent, primarily due to a reduced tax expense provided for an uncertain tax position partially offset by an increase in tax from higher pre-tax income during the three months ended March 31, 2014 as compared to the same period in 2013.

Effective May 1, 2013, the Company deconsolidated its previously held investment in Enogex Holdings and acquired a 28.5 percent equity interest in Enable which is being accounted for using the equity method of accounting. Prior to May 1, 2013, the Company reported the results of Enogex Holdings in two separate segments: the natural gas transportation and storage segment, and the natural gas gathering and processing segment. After the deconsolidation, these segments were combined into the natural gas midstream operations segment. The presentation of results for the three months ended March 31, 2013 have been revised to reflect this change.

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 2013 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 $253.9 million and $250.5 million at March 31, 2014 and December 31, 2013, respectively, an increase of $3.4 million, or 1.4 percent, primarily due to increases in billings to
32

partners of jointly-owned power plants and transmission revenue partially offset by a decrease in billings to OG&E's retail customers reflecting milder weather in March 2014 as compared to December 2013.
The balance of Accounts Payable was $209.6 million and $251.0 million at March 31, 2014 and December 31, 2013, respectively, a decrease of $41.4 million, or 16.5 percent, primarily due to a decrease in accruals.
Cash Flows

| Three Months Ended |  |

(In millions) | 2014 | 2013 | $ Change | % Change
Net cash provided from operating activities | $ | 23.2 |  | $ | 59.2 |  | $ | (36.0 | ) | (60.8 | )%
Net cash used in investing activities | (171.4 | ) | (289.5 | ) | 118.1 |  | 40.8 | %
Net cash provided from financing activities | 143.8 |  | 235.6 |  | (91.8 | ) | 39.0 | %

Operating Activities
The decrease of $36.0 million, or 60.8 percent, in net cash provided from operating activities during the three months ended March 31, 2014 as compared to the same period in 2013 was primarily due to:

• | increased vendor payments, including payments for ongoing maintenance at the power plants; and

• | the deconsolidation of Enogex Holdings on May 1, 2013.

Investing Activities
The decrease of $118.1 million, or 40.8 percent, in net cash used in investing activities during the three months ended March 31, 2014 as compared to the same period in 2013 was primarily due to lower levels of capital expenditures due to the deconsolidation of Enogex Holdings and a decreased level of transmission projects at OG&E.
Financing Activities
The decrease of $91.8 million, or 39.0 percent, in net cash provided from financing activities during the three months ended March 31, 2014 as compared to the same period in 2013 was primarily due to a decrease in short-term debt and the deconsolidation of Enogex Holdings partially offset by proceeds received from OG&E's issuance of long-term debt in March 2014.
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.
33

Capital Expenditures
The Company's consolidated estimates of capital expenditures for the years 2014 through 2018 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. The Company believes that Enable has, or will have access to, adequate liquidity and, therefore, no contributions are expected to be necessary to fund the capital expenditures of Enable from the general partners. Accordingly, capital expenditures for Enable are not included in the table below.

(D) | The capital expenditures above exclude any environmental expenditures associated with:

• | Pollution control equipment related to controlling SO 2 emissions under the regional haze requirements due to the uncertainty regarding the approach and timing for such pollution control equipment. The SO 2 emissions standards in the EPA's FIP could require the installation of Dry Scrubbers or fuel switching. OG&E estimates that installing such Dry Scrubbers could cost more than $1.0 billion. The FIP is being challenged by OG&E and the state of Oklahoma. On June 22, 2012, OG&E was granted a stay of the FIP by the U.S. Court of Appeals for the Tenth Circuit. On July 19, 2013, the U.S. Court of Appeals for the Tenth Circuit by a 2 to 1 vote denied the petition for review and affirmed the EPA's issuance of the FIP. On January 2, 2014, the Tenth Circuit confirmed that the stay of the FIP has remained in place and continues until the Tenth Circuit issues the mandate. A Petition for Certiorari was filed by the State of Oklahoma, the Industrial Consumers and OG&E with the United States Supreme Court on January 29, 2014. The mandate from the Tenth Circuit has been stayed until the Supreme Court acts on the petition. If the Supreme Court elects not to hear the case, OG&E will have approximately 55 months from the effective date of the lifting of the stay to achieve compliance with the FIP.

• | Installation of control equipment (other than activated carbon injection) for compliance with MATS by a deadline of April 16, 2016, which includes a one-year extension granted by the Oklahoma Department of Environmental Quality. As noted above, OG&E is currently planning to utilize activated carbon injection for the removal of mercury at each of its five coal-fired units, the capital costs of which are estimated to be approximately $20 million over a three year period and are included in the capital expenditures table in "Future Capital Requirements and Financing Activities" above. OG&E continues to review whether additional controls such as dry sorbent injection are needed for compliance with MATS. Current capital costs for installing the necessary control equipment for dry sorbent injection are estimated to be approximately $45 million over a three year period, but due to the uncertainty as to whether or not dry sorbent injection is necessary, such costs are not included in the capital expenditures table in "Future Capital Requirements and Financing Activities" above.

OG&E is currently evaluating options to comply with environmental requirements. For further information, see "Environmental Laws and Regulations" below.
Additional capital expenditures beyond those identified in the table above, including additional incremental growth opportunities in electric transmission assets, will be evaluated based upon 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 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, 2014, 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 $377.8 million and $439.6 million at March 31, 2014 and December 31, 2013, respectively. The weighted-average interest rate on short-term debt at March 31, 2014 was 0.28 percent. The average balance of short-term debt during the three months ended March 31, 2014 was $507.6 million at a weighted-average interest rate of 0.29 percent. The maximum month-end balance of short-term debt during the three months ended March 31, 2014 was $570.7 million. At March 31, 2014, there was $2.0 million supporting letters of credit at a weighted-average interest rate of 0.47 percent. At March 31, 2014, the Company had $770.2 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, 2013 and ending December 31, 2014. At March 31, 2014, the Company had $2.4 million in cash and cash equivalents. See Note 10 of Notes to Condensed Consolidated Financial Statements for a discussion of the Company's short-term debt activity.

Issuance of Long-Term Debt
On March 25, 2014, OG&E completed the issuance of $250 million of 4.55% senior notes due March 15, 2044. The proceeds from the issuance were added to OG&E's general funds and were used to repay short-term debt, fund capital expenditures and general corporate expenses, and utilized for working capital purposes. OG&E expects to issue additional long-term debt from time to time when market conditions are favorable and when the need arises.
Quarterly Distributions by Enable Midstream Partners
Pursuant to the Enable Midstream Partners Agreement, during the first quarter Enable Midstream Partners made distributions of approximately $32.5 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 2013 Form 10-K.
Commitments and Contingencies
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, except as otherwise stated in Notes 13 and 14 of Notes to Condensed Consolidated Financial Statements, under "Environmental Laws and Regulations" below and in Item 1 of Part II of this Form 10-Q, in Notes 15 and 16 of Notes to Consolidated Financial Statements and in Item 3 of Part I of the Company's 2013 Form 10-K, 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.
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 2013 Form 10-K. Except as set forth below, there have been no material changes to such items.
36

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
On June 15, 2005, the EPA issued final amendments to its 1999 regional haze rule. Regional haze is visibility impairment caused by the cumulative air pollutant emissions from numerous sources over a wide geographic area. The regional haze rule is intended to protect visibility in certain national parks and wilderness areas throughout the United States. In Oklahoma, the Wichita Mountains are the only area covered under the rule. However, Oklahoma's impact on parks in other states must also be evaluated.
As required by the Federal regional haze rule, the state of Oklahoma evaluated the installation of BART to reduce emissions that cause or contribute to regional haze from certain sources within the state that were built between 1962 and 1977. Certain of OG&E’s units at the Horseshoe Lake, Seminole, Muskogee and Sooner generating stations were evaluated for BART. On February 18, 2010, Oklahoma submitted its SIP to the EPA, which set forth the state's plan for compliance with the Federal 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. OG&E preliminarily estimates that the total capital cost of installing and operating these NO X controls on all covered units, based on recent industry experience and past projects, will be approximately $80 million. With respect to SO 2 emissions, the SIP included an agreement between the Oklahoma Department of Environmental Quality and OG&E that established BART for SO 2 control at the four affected coal-fired units located at OG&E's Sooner and Muskogee generating stations as the continued use of low sulfur coal (along with associated emission rates and limits). The SIP specifically rejected the installation and operation of Dry Scrubbers as BART for SO 2 control from these units because the state determined that Dry Scrubbers were not cost effective on these units.
On December 28, 2011, the EPA issued a final rule in which it rejected portions of the Oklahoma SIP and issued a FIP in their place. While the EPA accepted Oklahoma's BART determination for NO X in the final rule, it rejected Oklahoma's SO 2 BART determination with respect to the four coal-fired units at the Sooner and Muskogee generating stations. The EPA is instead requiring that OG&E meet an SO 2 emission rate of 0.06 pounds per million British thermal unit within five years. OG&E could meet the proposed standard by either installing and operating Dry Scrubbers or fuel switching at the four affected units. OG&E estimates that installing Dry Scrubbers on these units would include capital costs to OG&E of more than $1.0 billion. OG&E and the state of Oklahoma filed an administrative stay request with the EPA on February 24, 2012. The EPA has not yet responded to this request. OG&E and other parties also filed a petition for review of the FIP in the U.S. Court of Appeals for the Tenth Circuit on February 24, 2012 and a request to stay the FIP on April 4, 2012. On June 22, 2012, the U.S. Court of Appeals for the Tenth Circuit granted the stay request. On July 19, 2013, the U.S. Court of Appeals for the Tenth Circuit by a 2 to 1 vote denied the petition for review and affirmed the EPA's issuance of the FIP. On January 2, 2014, the Tenth Circuit confirmed that the stay of the FIP has remained in place and continues until the Tenth Circuit issues the mandate. A Petition for Certiorari was filed by the State of Oklahoma, the Industrial Consumers and OG&E with the United States Supreme Court on January 29, 2014. The mandate from the Tenth Circuit has been stayed until the Supreme Court acts on the petition. If the Supreme Court elects not to hear the case, OG&E will have approximately 55 months from the effective date of the lifting of the stay to achieve compliance with the FIP.
Cross-State Air Pollution Rule
As previously reported, on July 7, 2011, the EPA finalized its Cross-State Air Pollution Rule to replace the former Clean Air Interstate Rule that was remanded by a Federal court as a result of legal challenges. The final rule would require 27 states to reduce power plant emissions that contribute to ozone and particulate matter pollution in other states. On December 27, 2011, the EPA published a supplemental rule, which would make six additional states, including Oklahoma, subject to the Cross-State Air Pollution Rule for NO X emissions during the ozone-season from May 1 through September 30. Under the rule, OG&E would have been required to reduce ozone-season NO X emissions from its electrical generating units within the state beginning in 2012. The Cross-State Air Pollution Rule was challenged in court by numerous states and power generators. On December 30, 2011, the U.S. Court of Appeals issued a stay of the rule, which includes the supplemental rule, pending a decision on the merits. By
37

order dated August 21, 2012, the U.S. Court of Appeals vacated the Cross-State Air Pollution Rule and ordered the EPA to promulgate a replacement rule. On April 29, 2014, the U.S. Supreme Court reversed the decision by the U.S. Court of Appeals. It is anticipated that further proceedings will occur in the U.S. Court of Appeals and at EPA to establish new compliance deadlines. The Company's appeal of the supplemental rule, which applies to Oklahoma remains pending in the U.S. Court of Appeals and was not directly affected by the U.S. Supreme Court decision.
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. In recent years, the EPA has issued similar requests to numerous other electric utilities seeking to determine whether various maintenance, repair and replacement projects should have required permits under the Federal Clean Air Act's new source review process. In January 2012, OG&E received a supplemental request for an update of the previously provided information and for some additional information not previously requested. On May 1, 2012, OG&E responded to the EPA's supplemental request for information. On April 26, 2011, the EPA issued a notice of violation alleging that 13 projects occurred at OG&E's Muskogee and Sooner generating plants between 1993 and 2006 without the required new source review permits. The notice of violation also alleges that OG&E's visible emissions at its Muskogee and Sooner generating plants are not in accordance with applicable new source performance standards.
In March 2013, the DOJ informed OG&E that it was prepared to initiate enforcement litigation concerning the matters identified in the notice of violation. OG&E subsequently met with EPA and DOJ representatives regarding the notice of violation and proposals for resolving the matter without litigation. On July 8, 2013, the United States, at the request of the EPA, filed a complaint for declaratory relief against OG&E in United States District Court for the Western District of Oklahoma (Case No. CIV-13-690-D) 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. This complaint seeks to have OG&E submit a new assessment of whether the projects were likely to result in a significant emissions increase. The Sierra Club has intervened in this proceeding and has asserted claims for declaratory relief that are similar to those requested by the United States. OG&E expects to vigorously defend against these claims, but OG&E cannot predict the outcome of such litigation.
On August 12, 2013, the Sierra Club filed a complaint against OG&E in the United States District Court for the Eastern District of Oklahoma (Case No. 13-CV-00356) alleging that OG&E modifications made at Unit 6 of the Muskogee generating plant in 2008 were made without obtaining a prevention of significant deterioration permit and that the plant has 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 United States District Court for the Eastern District of Oklahoma dismissed the prevention of significant deterioration permit claim because it was filed after the statute of limitations expired, but the court allowed the opacity and particulate matter claims to proceed. At this time, OG&E continues to believe that it has acted in compliance with the Federal Clean Air Act.
If OG&E does not prevail in these proceedings and if a new assessment of the projects were to conclude that they caused a significant emissions increase, 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 $1.0 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. The cost of any required pollution control equipment could also be significant. OG&E cannot predict at this time whether it will be legally required to incur any of these costs.
Climate Change and Greenhouse Gas Emissions
There is continuing discussion and evaluation of possible global climate change in certain regulatory and legislative arenas. The focus is generally on emissions of greenhouse gases, including carbon dioxide, sulfur hexafluoride and methane, and whether these emissions are contributing to the warming of the Earth's atmosphere. There are various international agreements that restrict greenhouse gas emissions, but none of them have a binding effect on sources located in the United States. The U.S. Congress has not passed legislation to reduce emissions of greenhouse gases and the future prospects for any such legislation are uncertain, but the EPA has existing authority under the Clean Air Act to regulate greenhouse gas emissions from stationary sources. Several states have passed laws, adopted regulations or undertaken regulatory initiatives to reduce the emission of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and/or regional greenhouse gas cap and trade programs. Oklahoma and Arkansas are not among them. If legislation or regulations are passed at the Federal or state levels in the future requiring mandatory reductions of carbon dioxide and other greenhouse gases on the Company's facilities, this could result in significant additional compliance costs that would affect the Company’s future financial position, results of operations and cash flows if such costs are not recovered through regulated rates.
38

In January 2014, the EPA published reproposed New Source Performance Standards that specify permissible levels of greenhouse gas emissions from newly-constructed fossil fuel-fired electric generating units. The proposed New Source Performance Standards sets separate standards for natural gas combined cycle units and coal-fired generating units. As directed by President Obama's June 25, 2013, Climate Action Plan, and consistent with a 2010 settlement agreement, the EPA also announced plans to establish, pursuant to Section 111(d) of the Clean Air Act, carbon dioxide emissions standards for existing fossil fuel fired electric generating units. EPA plans to publish the proposed standards for existing units by June 1, 2014, and finalize those guidelines by June 1, 2015. States must then submit their individual plans for reducing power plants' greenhouse gas emissions to EPA by June 30, 2016.
The Company is continuing to review and evaluate available options for reducing, avoiding, offsetting or sequestering its greenhouse gas emissions.
Endangered Species
Certain Federal laws, including the Bald and Golden Eagle Protection Act, the Migratory Bird Treaty Act and the Endangered Species Act, provide special protection to certain designated species. These laws and any state equivalents provide for significant civil and criminal penalties for unpermitted activities that result in harm to or harassment of certain protected animals and plants, including damage to their habitats. If such species are located in an area in which the Company conducts operations, or if additional species in those areas become subject to protection, the Company’s operations and development projects, particularly transmission, wind or pipeline projects, could be restricted or delayed, or the Company could be required to implement expensive mitigation measures. The U.S. Fish and Wildlife Service announced a proposed rule to list the lesser prairie chicken as threatened on November 30, 2012. The decision applies to a 5-state area including parts of Oklahoma where OG&E has undertaken the development of certain large transmission projects. On March 10, 2014, the Company enrolled in the Western Association of Fish and Wildlife Agencies’ Range-Wide Conservation Plan for the lesser prairie chicken. This Range-Wide Conservation Plan consists of industry-specific conservation practices that apply to projects and activities in the impacted area. The Range-Wide Conservation Plan has been approved by the U.S. Fish and Wildlife Service and incorporated as part of the agency’s final decision on March 27th to list the lesser prairie chicken as a threatened species. More than 32 companies have enrolled in the Range-Wide Conservation Plan.
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 2013 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. The Company has an investment in an unconsolidated affiliate (see Note 3 of Notes to Condensed Consolidated Financial Statements). As the Company does not control this affiliate, its disclosure controls and procedures with respect to such affiliate is more limited than those the Company maintains with respect to its consolidated subsidiaries. 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).
