The accounts of the Company and its wholly owned subsidiaries are included in the Condensed Consolidated Financial Statements. All intercompany transactions and balances are eliminated in consolidation. The Company generally uses the equity method of accounting for investments where its ownership interest is between 20 percent and 50 percent and it lacks the power to direct activities that most significantly impact economic performance. </span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The electric utility segment</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas.&#160;Its operations</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are conducted through OG&amp;E and</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are subject to regulation by the OCC, the APSC and the FERC.

Enable was formed in 2013, and its general partner is equally controlled by the Company and CenterPoint, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, the Company accounts for its interest in Enable using the equity method of accounting. Enable is primarily 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 in the Anadarko, Arkoma and Ark-La-Tex Basins. Enable also owns crude oil gathering assets in the Anadarko and Williston Basins. Enable has intrastate natural gas transportation and storage assets that are located in Oklahoma as well as interstate assets that extend from western Oklahoma and the Texas Panhandle to Louisiana, from Louisiana to Illinois and from Louisiana to Alabama.</span></div></ix:nonNumeric></ix:nonNumeric></ix:nonNumeric><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div><a id="sA31E778ECDB258DF89CDCB7C966A6D70"></a></div><ix:nonNumeric contextRef="FD2019Q2YTD" name="us-gaap:BasisOfAccounting" id="TextSelection-076575EE214888DA9A4D4355313EEA2E-0-wk-Fact-783A0FC444C187CE96DB435530EFEC1A" escape="true"><ix:nonNumeric contextRef="FD2019Q2YTD" name="us-gaap:BasisOfAccountingPolicyPolicyTextBlock" id="TextSelection-3FF443D825B9679529304355313DEB69-0-wk-Fact-0BC3B770E0023FB022D8435530E03288" continuedAt="TextSelection-3FF443D825B9679529304355313DEB69-1" escape="true"><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-weight:bold;">Basis of Presentation</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Condensed</span><span style="font-family:inherit;font-size:10pt;"> Consolidated </span><span style="font-family:inherit;font-size:10pt;">Financial Statements included herein have been prepared by</span><span style="font-family:inherit;font-size:10pt;"> the Company, </span><span style="font-family:inherit;font-size:10pt;">without audit, pursuant to the rules and regulations of the Securities and Exchange Commission.

style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The main difference between prior lease accounting and Topic 842 is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases under current accounting guidance</span><span style="font-family:inherit;font-size:10pt;">. </span><span style="font-family:inherit;font-size:10pt;">Lessees, such as</span><span style="font-family:inherit;font-size:10pt;"> the Company, </span><span style="font-family:inherit;font-size:10pt;">recognize a right-of-use asset and a lease liability for virtually all of their leases, other than leases that meet the definition of a short-term lease. The liability is equal to the present value of lease payments. The asset is based on the liability, subject to adjustment for items such as initial direct costs.</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">For income statement purposes, Topic 842 retains a dual model, requiring leases to be classified as either operating or finance. Operating leases result in straight-line expense, while finance leases result in a front-loaded expense pattern, similar to prior capital leases. Classification of operating and finance leases is based on criteria that are largely similar to those applied in prior lease guidance but without the explicit thresholds.</span><span style="font-family:inherit;font-size:10pt;"> The Company </span><span style="font-family:inherit;font-size:10pt;">adopted this standard in the first quarter of 2019 utilizing the modified retrospective transition method.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></ix:continuation><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 11</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;text-align:right;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><ix:continuation id="TextSelection-22F45F8D88E8F791571E435531408DBD-2" continuedAt="TextSelection-22F45F8D88E8F791571E435531408DBD-3"><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Various practical expedients for the application of Topic 842 were approved, and</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">elected to apply the below:</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;

If a lease is identified,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">recognizes a right-of-use asset and a lease liability in its</span><span style="font-family:inherit;font-size:10pt;"> Consolidated Balance Sheets. The Company </span><span style="font-family:inherit;font-size:10pt;">recognizes and measures a lease liability when it concludes the contract contains an identified asset that</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">controls through having the right to obtain substantially all of the economic benefits and the right to direct the use of the identified asset. The liability is equal to the present value of lease payments, and the asset is based on the liability, subject to adjustment, such as for initial direct costs. Further,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> utilizes an incremental borrowing rate for purposes of measuring lease liabilities, if the discount rate is not implicit in the lease. To calculate the incremental borrowing rate,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> starts with a current pricing report for</span><span style="font-family:inherit;font-size:10pt;"> the Company's</span><span style="font-family:inherit;font-size:10pt;"> senior unsecured notes, which indicates rates for periods reflective of the lease term, and adjusts for the effects of collateral to arrive at the secured incremental borrowing rate. As permitted by Topic 842,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">made an accounting policy election to not apply the balance sheet recognition requirements to short-term leases and to not separate lease components from nonlease components when recognizing and measuring lease liabilities. For income statement purposes,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">records operating lease expense on a straight-line basis.</span></ix:continuation><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Based on its evaluation of all contracts under Topic 842, as described above,</span><span style="font-family:inherit;font-size:10pt;"> the Company concluded it has operating lease obligations for OG&amp;E railcar leases, OG&amp;E wind farm land leases and the Company's office space lease.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">Operating Leases</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">OG&amp;E Railcar Lease Agreement</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Effective February 1, 2019, OG&amp;E renewed a railcar lease agreement for 780 rotary gondola railcars to transport coal from Wyoming to OG&amp;E's coal-fired generation units.

While lease liabilities are not remeasured as a result of changes to the Consumer Price Index, changes to the Consumer Price Index are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. The OU Spirit and Crossroads leases have rent escalations which increase after five and 10 years. Although the leases are cancellable, OG&amp;E is required to make annual lease payments as long as the wind turbines are located on the land.

In certain circumstances, the general partner has 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.  </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Distributions received from Enable were </span><span style="font-family:inherit;font-size:10pt;"><span>$<ix:nonFraction id="d104209119e2426-wk-Fact-4FAA2481488F93DAE89F4355311EF4AE" name="us-gaap:EquityMethodInvestmentDividendsOrDistributions" contextRef="FD2019Q2QTD_dei_LegalEntityAxis_oge_EnableMidstreamPartnersMember" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">35.3</ix:nonFraction> million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$<ix:nonFraction id="d104209119e2430-wk-Fact-1BC8B16E5F5CD42D869B43553052679E" name="us-gaap:EquityMethodInvestmentDividendsOrDistributions" contextRef="FD2019Q2YTD_dei_LegalEntityAxis_oge_EnableMidstreamPartnersMember" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">70.6</ix:nonFraction> million</span></span><span style="font-family:inherit;font-size:10pt;"> during both the </span><span style="font-family:inherit;font-size:10pt;">three months ended</span><span style="font-family:inherit;font-size:10pt;"> and both the </span><span style="font-family:inherit;font-size:10pt;">six months ended</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">2018</span><span style="font-family:inherit;font-size:10pt;">, respectively.</span></div><div style="line-height:120%;text-align:justify;text-indent:49px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-weight:bold;">Related Party Transactions</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company </span><span style="font-family:inherit;font-size:10pt;">charges operating costs to OG&amp;E</span><span style="font-family:inherit;font-size:10pt;"> and Enable </span><span style="font-family:inherit;font-size:10pt;">based on several factors, and operating costs directly related to OG&amp;E</span><span style="font-family:inherit;font-size:10pt;"> and/or Enable </span><span style="font-family:inherit;font-size:10pt;">are assigned as such.&#160;Operating costs incurred for the benefit of OG&amp;E are allocated either as overhead based primarily on labor costs&#160;or using the "Distrigas" method, which is a three-factor formula that uses an equal weighting of payroll, net operating revenues and gross property, plant and equipment.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">The Company and Enable</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company and Enable are currently parties to several agreements whereby the Company provides specified support services to Enable, such as certain information technology, payroll and benefits administration.

The accounts of the Company and its wholly owned subsidiaries are included in the Condensed Consolidated Financial Statements. All intercompany transactions and balances are eliminated in consolidation. The Company generally uses the equity method of accounting for investments where its ownership interest is between 20 percent and 50 percent and it lacks the power to direct activities that most significantly impact economic performance. </span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The electric utility segment</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas.&#160;Its operations</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are conducted through OG&amp;E and</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are subject to regulation by the OCC, the APSC and the FERC.

Enable was formed in 2013, and its general partner is equally controlled by the Company and CenterPoint, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, the Company accounts for its interest in Enable using the equity method of accounting. Enable is primarily 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 in the Anadarko, Arkoma and Ark-La-Tex Basins. Enable also owns crude oil gathering assets in the Anadarko and Williston Basins. Enable has intrastate natural gas transportation and storage assets that are located in Oklahoma as well as interstate assets that extend from western Oklahoma and the Texas Panhandle to Louisiana, from Louisiana to Illinois and from Louisiana to Alabama.</span><span style="font-family:inherit;font-size:10pt;"> As disclosed in the Company's </span><a style="font-family:inherit;font-size:10pt;" href="http://www.sec.gov/Archives/edgar/data/1021635/000102163519000015/a2018ogeenergy10-k.htm"><span style="font-family:inherit;font-size:10pt;">2018 Form 10-K</span></a><span style="font-family:inherit;font-size:10pt;">, Enable is subject to a number of risks, including contract renewal risk, the reliance on the drilling and production decisions of others and the volatility of natural gas, NGLs and crude oil prices.

The Company's financial objectives include a long-term annual earnings growth rate for OG&amp;E of four to six percent on a weather-normalized basis, maintaining a strong credit rating as well as targeting dividend increases of approximately 10 percent annually through 2019. The Company also utilizes cash distributions from its investment in Enable to help fund its capital needs and support future dividend growth. The Company believes it can accomplish these financial objectives by, among other things, pursuing multiple avenues to build its business, maintaining a diversified asset position, continuing to develop a wide range of skills to succeed with changes in its industries, providing products and services to customers efficiently, managing risks effectively and having strong regulatory and legislative relationships. </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 28</span></div></div><hr style="page-break-after:always"></hr><div><a id="sA6AB7A1D707058828215BF90AF5D426A"></a></div><div><div style="line-height:120%;text-align:right;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;padding-bottom:13px;text-align:justify;font-size:10pt;"><span style="font-style:italic;font-weight:bold;">Summary of Operating Results</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Three Months Ended</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> as compared to </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Three Months Ended</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">June&#160;30, 2018</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Net income was</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">$100.2 million</span><span style="font-family:inherit;font-size:10pt;">, </span><span style="font-family:inherit;font-size:10pt;">or</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">$0.50</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">per diluted share, during the</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">three months ended</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;color:#000000;font-weight:normal;text-decoration:none;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">as compared to</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">$110.7 million</span><span style="font-family:inherit;font-size:10pt;">, </span><span style="font-family:inherit;font-size:10pt;">or</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">$0.55</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">per diluted share, during the same period in</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">2018</span><span style="font-family:inherit;font-size:10pt;">. </span><span style="font-family:inherit;font-size:10pt;">The</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">decrease</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">in net income of</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">$10.5 million</span><span style="font-family:inherit;font-size:10pt;">, or </span><span style="font-family:inherit;font-size:10pt;">$0.05</span><span style="font-family:inherit;font-size:10pt;"> per diluted share, </span><span style="font-family:inherit;font-size:10pt;">is further discussed below.</span></div><div style="line-height:120%;text-align:justify;padding-left:72px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;

Cost of sales, as reflected on the income statement, includes 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&amp;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&amp;E's definition of gross margin may be different from similar terms used by other companies. Further, gross margin is not intended to replace operating revenues as determined in accordance with GAAP as an indicator of operating performance.

Total revenues consist of the fees that Enable charges its customers and the sales price of natural gas and NGLs that Enable sells. The cost of natural gas and NGLs consists of the purchase price of natural gas and NGLs that Enable purchases. Enable deducts the cost of natural gas and NGLs from total revenues to arrive at a measure of the core profitability of their mix of fee-based and commodity-based customer arrangements. Gross margin allows for meaningful comparison of the operating results between Enable's fee-based revenues and Enable's commodity-based contracts which involve the purchase or sale of natural gas, NGLs and/or crude oil. In addition, the Company believes gross margin allows for a meaningful comparison of the results of Enable's commodity-based activities across different commodity price environments because it measures the spread between the product sales price and cost of products sold.

OG&amp;E's deployment of Smart Grid technology helps to reduce the peak load demand. OG&amp;E is also deploying more renewable energy sources that do not emit greenhouse gases. OG&amp;E's service territory borders one of the nation's best wind resource areas, and OG&amp;E has leveraged its geographic position to develop renewable energy resources and completed transmission investments to deliver the renewable energy. The SPP has begun to authorize the construction of transmission lines capable of bringing renewable energy out of the wind resource areas in western Oklahoma, the Texas Panhandle and western Kansas to load centers by planning for more transmission to be built in the area. In addition to increasing overall system reliability, these new transmission resources should provide greater access to additional wind resources that are currently constrained due to existing transmission delivery limitations.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span>On October 23, 2015, the EPA published the final Clean Power Plan that established standards of performance for CO</span><span><sub style="vertical-align:bottom;line-height:120%;font-size:7pt">2</sub></span><span> emissions from existing fossil-fuel-fired power plants along with state-specific CO</span><span><sub style="vertical-align:bottom;line-height:120%;font-size:7pt">2</sub></span><span> reduction standards expressed as both rate-based (lbs./MWh) and mass-based (tons/yr.) goals.</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">On July 8, 2019, the EPA officially repealed the Clean Power Plan and published the Affordable Clean Energy rule to replace it.

OG&amp;E expects to be able to provide a reasonable estimate of any material costs associated with the rule's implementation following issuance of the permits from the State of Oklahoma.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 44</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;text-align:right;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div></div><div><br/></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-style:italic;font-weight:bold;">Site Remediation</span><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"> </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Comprehensive Environmental Response, Compensation and Liability Act of 1980 and comparable state laws impose liability, without regard to the legality of the original conduct, on certain classes of persons responsible for the release of hazardous substances into the environment.

accordance with the Uniform System of Accounts prescribed by the FERC and adopted by the OCC and the APSC.&#160;Additionally, OG&amp;amp;E, as a regulated utility, is subject to accounting principles for certain types of rate-regulated activities, which provide that certain incurred costs that would otherwise be charged to expense can be deferred as regulatory assets, based on the expected recovery from customers in future rates.&#160;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.&#160;Management's expected recovery of deferred costs and flowback of deferred credits generally results from specific decisions by regulators granting such ratemaking treatment.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div

The Company determined that its contribution of Enogex LLC to Enable met the requirements of being in substance real estate and recorded the contribution at historical cost. The formation of Enable was considered a business combination, and CenterPoint was the acquirer of Enogex Holdings for accounting purposes.&#160;Under this method, the fair value of the consideration paid by CenterPoint for Enogex Holdings was allocated to the assets acquired and liabilities assumed based on their fair value.&#160;Enogex Holdings' assets, liabilities and equity were accordingly adjusted to estimated fair value, resulting in an increase to Enable's equity of&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$2.2 billion&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. Since the contribution of Enogex LLC to Enable was recorded 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. As prior real estate sales accounting guidance was superseded by ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;gains or losses on sales or dilution events in the Company's investment in Enable within the Company's earnings, net of proportional basis difference recognition.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;At &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the Company owned &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;111.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; common units, or &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;25.5 percent&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, of Enable's outstanding common units. On&#160;June 28, 2019, Enable's common unit price closed at&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$13.71&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. The Company recorded equity in earnings of unconsolidated affiliates of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$35.8 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$29.3 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; for the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;three months ended&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$66.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$63.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; for the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;six months ended&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively. Equity in earnings of unconsolidated affiliates includes the Company's share of Enable's earnings adjusted for the amortization of the basis difference of the Company's original investment in Enogex LLC and its underlying equity in the net assets of Enable. The basis difference is being amortized, beginning in 2013, over the average life of the assets to which the basis difference is attributed, which is approximately 30 years. Equity in earnings of unconsolidated affiliates is also adjusted for the elimination of the Enogex Holdings fair value adjustments, as described above. These amortizations may also include gain or loss on dilution, net of proportional basis difference recognition.&lt;/span&gt;&lt;/div&gt;&lt;div

The main difference between prior lease accounting and Topic 842 is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases under current accounting guidance&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Lessees, such as&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;recognize a right-of-use asset and a lease liability for virtually all of their leases, other than leases that meet the definition of a short-term lease. The liability is equal to the present value of lease payments. The asset is based on the liability, subject to adjustment for items such as initial direct costs.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;For income statement purposes, Topic 842 retains a dual model, requiring leases to be classified as either operating or finance. Operating leases result in straight-line expense, while finance leases result in a front-loaded expense pattern, similar to prior capital leases. Classification of operating and finance leases is based on criteria that are largely similar to those applied in prior lease guidance but without the explicit thresholds.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; The Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;adopted this standard in the first quarter of 2019 utilizing the modified retrospective transition method.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;

If a lease is identified,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;recognizes a right-of-use asset and a lease liability in its&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; Consolidated Balance Sheets. The Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;recognizes and measures a lease liability when it concludes the contract contains an identified asset that&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;controls through having the right to obtain substantially all of the economic benefits and the right to direct the use of the identified asset. The liability is equal to the present value of lease payments, and the asset is based on the liability, subject to adjustment, such as for initial direct costs. Further,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; utilizes an incremental borrowing rate for purposes of measuring lease liabilities, if the discount rate is not implicit in the lease. To calculate the incremental borrowing rate,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; starts with a current pricing report for&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company's&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; senior unsecured notes, which indicates rates for periods reflective of the lease term, and adjusts for the effects of collateral to arrive at the secured incremental borrowing rate. As permitted by Topic 842,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;made an accounting policy election to not apply the balance sheet recognition requirements to short-term leases and to not separate lease components from nonlease components when recognizing and measuring lease liabilities. For income statement purposes,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;records operating lease expense on a straight-line basis.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Based on its evaluation of all contracts under Topic 842, as described above,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company concluded it has operating lease obligations for OG&amp;amp;E railcar leases, OG&amp;amp;E wind farm land leases and the Company's office space lease.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-weight:bold;"&gt;Operating Leases&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;OG&amp;amp;E Railcar Lease Agreement&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Effective February 1, 2019, OG&amp;amp;E renewed a railcar lease agreement for 780 rotary gondola railcars to transport coal from Wyoming to OG&amp;amp;E's coal-fired generation units. Rental payments are charged to fuel expense and are recovered through OG&amp;amp;E's fuel adjustment clauses. On February 1, 2024, OG&amp;amp;E has the option to either purchase the railcars at a stipulated fair market value or renew the lease. If OG&amp;amp;E chooses not to purchase the railcars or renew the lease agreement and the actual fair value of the railcars is less than the stipulated fair market value, OG&amp;amp;E would be responsible for the difference in those values up to a maximum of&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$6.8 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;OG&amp;amp;E Wind Farm Land Lease Agreements&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company has operating leases related to land for OG&amp;amp;E's Centennial, OU Spirit and Crossroads wind farms with terms of 25 to 30 years. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Centennial lease has rent escalations which increase annually based on the Consumer Price Index. While lease liabilities are not remeasured as a result of changes to the Consumer Price Index, changes to the Consumer Price Index are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. The OU Spirit and Crossroads leases have rent escalations which increase after five and 10 years. Although the leases are cancellable, OG&amp;amp;E is required to make annual lease payments as long as the wind turbines are located on the land. OG&amp;amp;E does not expect to terminate the leases until the wind turbines reach the end of their useful life.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;

If a lease is identified,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;recognizes a right-of-use asset and a lease liability in its&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; Consolidated Balance Sheets.

The liability is equal to the present value of lease payments, and the asset is based on the liability, subject to adjustment, such as for initial direct costs. Further,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; utilizes an incremental borrowing rate for purposes of measuring lease liabilities, if the discount rate is not implicit in the lease.

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&#160;1), and the lowest priority given to unobservable inputs (Level&#160;3).&#160;Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.&#160;The three levels defined in the fair value hierarchy are as follows:&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Level 1 inputs are quoted prices in active markets for identical unrestricted assets or liabilities that are accessible at the measurement date.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;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.&#160;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.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;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).&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div

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&#160;1), and the lowest priority given to unobservable inputs (Level&#160;3).&#160;Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.&#160;The three levels defined in the fair value hierarchy are as follows:&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Level 1 inputs are quoted prices in active markets for identical unrestricted assets or liabilities that are accessible at the measurement date.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;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.&#160;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.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;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).

accrued and unpaid interest to the date of purchase.&#160;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.&#160;The repayment option may only be exercised by the holder of a bond for the principal amount.&#160;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.&#160;This process occurs once per week.&#160;Since the original issuance of these series of bonds in 1995 and 1997, the remarketing agent has successfully remarketed all tendered bonds.&#160;If the remarketing agent is unable to remarket any such bonds, OG&amp;amp;E is obligated to repurchase such unremarketed bonds.&#160;As OG&amp;amp;E has both the intent and ability to refinance the bonds on a long-term

These laws and regulations can change, restrict or otherwise impact OG&amp;amp;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. Management believes that all of its operations are in substantial compliance with current federal, state and local environmental standards.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;   &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Environmental regulation can increase the cost of planning, design, initial installation and operation of OG&amp;amp;E's facilities.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Management continues to evaluate its compliance with existing and proposed environmental legislation and regulations and implement appropriate environmental programs in a competitive market.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-weight:bold;"&gt;Other&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:8pt;"&gt;&lt;span style="font-family:inherit;font-size:8pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In the normal course of business,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;the Company&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;is confronted with issues or events that may result in a contingent liability.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;These generally relate to lawsuits or claims made by third parties, including governmental agencies.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;When appropriate, management consults with legal counsel and other experts to assess the claim.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;If, in management's opinion,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;the Company&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;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&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company's &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Condensed&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; Consolidated &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Financial Statements.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;At the present time, based on currently available information,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;believes that any reasonably possible losses in excess of accrued amounts arising out of pending or threatened lawsuits or claims would not have a material adverse effect on&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company's consolidated &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;financial position, results of operations or cash flows.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;                                    &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$53.5 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The purchase of these assets replaces capacity provided by purchased power contracts that have expired or are expiring in 2019 and helps OG&amp;amp;E satisfy its customers' energy needs and load obligations to the SPP. In addition, the filing sought approval of a rider mechanism to collect costs associated with the purchase of these generating facilities. On May 13, 2019, the OCC approved OG&amp;amp;E's acquisition of both plants, the requested rider mechanism for the AES plant and regulatory asset treatment for the Oklahoma Cogeneration LLC plant that will defer non-fuel operation and maintenance expenses, depreciation and ad valorem taxes.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;On January 23, 2019, OG&amp;amp;E filed an application for Federal Power Act Section 203 approval with a request for expedited consideration. This application requested FERC's prior authorization to acquire the AES and Oklahoma Cogeneration LLC plants. On May 22, 2019, OG&amp;amp;E received authorization from the FERC to acquire both plants.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In May 2019, OG&amp;amp;E completed the acquisition of the power plant from AES and placed it into service, which is now named the River Valley power plant. Closing for the acquisition of the power plant from Oklahoma Cogeneration LLC is anticipated during the third quarter of 2019.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;span style="font-style:italic;font-weight:bold;"&gt;Fuel Adjustment Clause Review for Calendar Year 2017 &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In July 2018, the OCC staff filed an application to review OG&amp;amp;E's fuel adjustment clause for the calendar year 2017, including the prudence of OG&amp;amp;E's electric generation, purchased power and fuel procurement costs. On February 1, 2019, the ALJ recommended that OG&amp;amp;E's processes, costs, investments and decisions regarding fuel procurement for the 2017 calendar year be found prudent. On May 22, 2019, the OCC deemed OG&amp;amp;E's electric generation, purchased power and fuel procurement costs to be materially prudent.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-weight:bold;"&gt;Pending Regulatory Matters&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Set forth below is a list of various proceedings pending before state or federal regulatory agencies. Unless stated otherwise, OG&amp;amp;E cannot predict when the regulatory agency will act or what action the regulatory agency will take. OG&amp;amp;E's financial results are dependent in part on timely and adequate decisions by the regulatory agencies that set OG&amp;amp;E's rates.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-style:italic;font-weight:bold;"&gt;FERC - Section 206 Filing&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In January 2018, the Oklahoma Municipal Power Authority filed a complaint at the FERC stating that the base return on common equity used by OG&amp;amp;E in calculating formula transmission rates under the SPP Open Access Transmission Tariff is unjust and unreasonable and should be reduced from&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;10.60 percent&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;7.85 percent&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, effective upon the date of the complaint.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In addition to the request to reduce the return on equity, the Oklahoma Municipal Power Authority's complaint also requests that modifications be made to OG&amp;amp;E's transmission formula rates to reflect the impacts of the 2017 Tax Act, including the 2017 Tax Act's impact on accumulated deferred income tax balances. In May 2019, all parties agreed to a settlement which provides for 10 percent base return on equity, plus a 50-basis point adder, and a five-year amortization period of the unprotected excess accumulated deferred income taxes associated with the 2017 Tax Act. While pending approval by the FERC, interim rates are currently being applied by the SPP pursuant to the terms of the settlement agreement.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-style:italic;font-weight:bold;"&gt;Oklahoma Rate Review Filing - December 2018 &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In December 2018, OG&amp;amp;E filed a general rate review with the OCC, requesting a rate increase of&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$77.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;per year to recover its investment in the Dry Scrubbers project and in the conversion of Muskogee Units 4 and 5 to natural gas. The filing also sought to align OG&amp;amp;E's return on equity more closely to the industry average and to align OG&amp;amp;E's depreciation rates to more realistically reflect its assets' lifespans.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;On May 24, 2019, OG&amp;amp;E entered into a non-unanimous joint stipulation and settlement agreement with the OCC staff, the Attorney General's Office of Oklahoma, the Oklahoma Industrial Energy Consumers and other certain parties associated with the requested rate increase. The filing was further amended on May 30, 2019 to include Oklahoma Association of Electric Cooperatives as a settling party. The settlement is subject to OCC approval. Under the terms of the settlement agreement, OG&amp;amp;E would receive full recovery of its environmental investments in the Dry Scrubbers project and in the conversion of Muskogee Units 4 and 5 to natural gas. Base rates would not change as a result of the settlement agreement due to the reduction of costs related to cogeneration contracts and the acceleration of unprotected deferred tax savings over a 10-year period. Further, OG&amp;amp;E's current depreciation rates and return on equity of 9.5 percent for purposes of calculating the allowance for funds used during construction and OG&amp;amp;E's various recovery riders that include a full return component would remain unchanged.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;On July 1, 2019, OG&amp;amp;E implemented interim rates, which are subject to refund of any amount recovered in excess of the rates ultimately approved by the OCC in the rate review.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;On July 12, 2019, the ALJ issued a report that recommended approval of the settlement agreement and found the settlement agreement fair, just, reasonable and in the public interest. The ALJ's report also recommended that OG&amp;amp;E's environmental compliance decisions and costs related to the Dry Scrubbers project and the conversion of Muskogee Units 4 and 5 to natural gas be found prudent and used and useful with cost recovery allowed. These recommendations are subject to approval by the OCC. A hearing on exceptions was held on August 6, 2019, and OG&amp;amp;E is awaiting a final order from the OCC.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Dry Scrubbers project, which includes the installation of two dry scrubbers at the Sooner plant, and the conversion of Muskogee Units 4 and 5 to natural gas were initiated in response to the EPA's MATS and Regional Haze Rule FIP. The Dry Scrubber systems on Sooner Unit 1 and Unit 2 were placed into service in October 2018 and January 2019, respectively. Muskogee Units 4 and 5 were placed into service in March 2019.

However, SPP had informed participants in the market that these charges would be forthcoming.&#160;In July 2016, the FERC granted SPP's request to recover the charges not billed since 2008. SPP subsequently billed OG&amp;amp;E for these charges and credited OG&amp;amp;E related to transmission upgrades that OG&amp;amp;E had sponsored, which resulted in OG&amp;amp;E being a net receiver of sponsored upgrade credits.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The majority of these net credits were refunded to customers through OG&amp;amp;E's various rate riders that include SPP activity with the remaining amounts retained by OG&amp;amp;E.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Several impacted companies sought rehearing of the FERC's July 2016 order; however, in November 2017, the FERC denied the rehearing requests. In January 2018, one of the impacted companies appealed the FERC's decision to the U.S. Court of Appeals for the District of Columbia. In July 2018, the U.S. Court of Appeals for the District of Columbia granted a motion requested by the FERC that the case be remanded back to the FERC for further examination and proceedings. In February 2019, the FERC reversed its July 2016 order and ordered SPP to develop a plan to refund the payments but not to implement the refunds until further ordered to do so. In response, on April 1, 2019, OG&amp;amp;E filed a request for rehearing with the FERC, and on May 24, 2019, OG&amp;amp;E filed a FERC 206 complaint against SPP, alleging SPP's forced unwinding of the revenue credit payments to OG&amp;amp;E would violate the provisions of the Sponsored Upgrade Agreement. OG&amp;amp;E's filing requested that the FERC rule that SPP is not entitled to seek refunds or in any other way seek to unwind the revenue credit payments it had paid to OG&amp;amp;E pursuant to the Sponsored Upgrade Agreement.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;cannot predict the outcome of this proceeding based on currently available information, and as of&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;and at present time,&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; the Company &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;has not reserved an amount for a potential refund.

The accounts of the Company and its wholly owned subsidiaries are included in the Condensed Consolidated Financial Statements. All intercompany transactions and balances are eliminated in consolidation. The Company generally uses the equity method of accounting for investments where its ownership interest is between 20 percent and 50 percent and it lacks the power to direct activities that most significantly impact economic performance. </span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The electric utility segment</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas.&#160;Its operations</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are conducted through OG&amp;E and</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are subject to regulation by the OCC, the APSC and the FERC.

Enable was formed in 2013, and its general partner is equally controlled by the Company and CenterPoint, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, the Company accounts for its interest in Enable using the equity method of accounting. Enable is primarily 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 in the Anadarko, Arkoma and Ark-La-Tex Basins. Enable also owns crude oil gathering assets in the Anadarko and Williston Basins. Enable has intrastate natural gas transportation and storage assets that are located in Oklahoma as well as interstate assets that extend from western Oklahoma and the Texas Panhandle to Louisiana, from Louisiana to Illinois and from Louisiana to Alabama.</span></div><span></span>

The main difference between prior lease accounting and Topic 842 is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases under current accounting guidance</span><span style="font-family:inherit;font-size:10pt;">. </span><span style="font-family:inherit;font-size:10pt;">Lessees, such as</span><span style="font-family:inherit;font-size:10pt;"> the Company, </span><span style="font-family:inherit;font-size:10pt;">recognize a right-of-use asset and a lease liability for virtually all of their leases, other than leases that meet the definition of a short-term lease. The liability is equal to the present value of lease payments. The asset is based on the liability, subject to adjustment for items such as initial direct costs.</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">For income statement purposes, Topic 842 retains a dual model, requiring leases to be classified as either operating or finance. Operating leases result in straight-line expense, while finance leases result in a front-loaded expense pattern, similar to prior capital leases. Classification of operating and finance leases is based on criteria that are largely similar to those applied in prior lease guidance but without the explicit thresholds.</span><span style="font-family:inherit;font-size:10pt;"> The Company </span><span style="font-family:inherit;font-size:10pt;">adopted this standard in the first quarter of 2019 utilizing the modified retrospective transition method.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Various practical expedients for the application of Topic 842 were approved, and</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">elected to apply the below:</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;

If a lease is identified,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">recognizes a right-of-use asset and a lease liability in its</span><span style="font-family:inherit;font-size:10pt;"> Consolidated Balance Sheets. The Company </span><span style="font-family:inherit;font-size:10pt;">recognizes and measures a lease liability when it concludes the contract contains an identified asset that</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">controls through having the right to obtain substantially all of the economic benefits and the right to direct the use of the identified asset. The liability is equal to the present value of lease payments, and the asset is based on the liability, subject to adjustment, such as for initial direct costs. Further,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> utilizes an incremental borrowing rate for purposes of measuring lease liabilities, if the discount rate is not implicit in the lease. To calculate the incremental borrowing rate,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> starts with a current pricing report for</span><span style="font-family:inherit;font-size:10pt;"> the Company's</span><span style="font-family:inherit;font-size:10pt;"> senior unsecured notes, which indicates rates for periods reflective of the lease term, and adjusts for the effects of collateral to arrive at the secured incremental borrowing rate. As permitted by Topic 842,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">made an accounting policy election to not apply the balance sheet recognition requirements to short-term leases and to not separate lease components from nonlease components when recognizing and measuring lease liabilities. For income statement purposes,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">records operating lease expense on a straight-line basis.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Based on its evaluation of all contracts under Topic 842, as described above,</span><span style="font-family:inherit;font-size:10pt;"> the Company concluded it has operating lease obligations for OG&amp;E railcar leases, OG&amp;E wind farm land leases and the Company's office space lease.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">Operating Leases</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">OG&amp;E Railcar Lease Agreement</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Effective February 1, 2019, OG&amp;E renewed a railcar lease agreement for 780 rotary gondola railcars to transport coal from Wyoming to OG&amp;E's coal-fired generation units. Rental payments are charged to fuel expense and are recovered through OG&amp;E's fuel adjustment clauses. On February 1, 2024, OG&amp;E has the option to either purchase the railcars at a stipulated fair market value or renew the lease. If OG&amp;E chooses not to purchase the railcars or renew the lease agreement and the actual fair value of the railcars is less than the stipulated fair market value, OG&amp;E would be responsible for the difference in those values up to a maximum of</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;"><span>$6.8 million</span></span><span style="font-family:inherit;font-size:10pt;">.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">OG&amp;E Wind Farm Land Lease Agreements</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company has operating leases related to land for OG&amp;E's Centennial, OU Spirit and Crossroads wind farms with terms of 25 to 30 years. </span><span style="font-family:inherit;font-size:10pt;">The Centennial lease has rent escalations which increase annually based on the Consumer Price Index. While lease liabilities are not remeasured as a result of changes to the Consumer Price Index, changes to the Consumer Price Index are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. The OU Spirit and Crossroads leases have rent escalations which increase after five and 10 years. Although the leases are cancellable, OG&amp;E is required to make annual lease payments as long as the wind turbines are located on the land. OG&amp;E does not expect to terminate the leases until the wind turbines reach the end of their useful life.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div

However, the Company 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; therefore, the Company accounts for its 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 as adjusted for basis differences. The Company's maximum exposure to loss related to Enable is limited to the Company's equity investment in Enable at </span><span style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;"> as presented in Note 13.

The Company determined that its contribution of Enogex LLC to Enable met the requirements of being in substance real estate and recorded the contribution at historical cost. The formation of Enable was considered a business combination, and CenterPoint was the acquirer of Enogex Holdings for accounting purposes.&#160;Under this method, the fair value of the consideration paid by CenterPoint for Enogex Holdings was allocated to the assets acquired and liabilities assumed based on their fair value.&#160;Enogex Holdings' assets, liabilities and equity were accordingly adjusted to estimated fair value, resulting in an increase to Enable's equity of</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;"><span>$2.2 billion</span></span><span style="font-family:inherit;font-size:10pt;">. Since the contribution of Enogex LLC to Enable was recorded 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. As prior real estate sales accounting guidance was superseded by ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets," the Company recognizes </span></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">gains or losses on sales or dilution events in the Company's investment in Enable within the Company's earnings, net of proportional basis difference recognition.</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">At </span><span style="font-family:inherit;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;">, the Company owned </span><span style="font-family:inherit;font-size:10pt;"><span>111.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> common units, or </span><span style="font-family:inherit;font-size:10pt;"><span>25.5 percent</span></span><span style="font-family:inherit;font-size:10pt;">, of Enable's outstanding common units.

Equity in earnings of unconsolidated affiliates includes the Company's share of Enable's earnings adjusted for the amortization of the basis difference of the Company's original investment in Enogex LLC and its underlying equity in the net assets of Enable. The basis difference is being amortized, beginning in 2013, over the average life of the assets to which the basis difference is attributed, which is approximately 30 years. Equity in earnings of unconsolidated affiliates is also adjusted for the elimination of the Enogex Holdings fair value adjustments, as described above. These amortizations may also include gain or loss on dilution, net of proportional basis difference recognition.</span></div><div

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&#160;1), and the lowest priority given to unobservable inputs (Level&#160;3).&#160;Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.&#160;The three levels defined in the fair value hierarchy are as follows:</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Level 1 inputs are quoted prices in active markets for identical unrestricted assets or liabilities that are accessible at the measurement date.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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.&#160;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.</span><span style="font-family:inherit;font-size:10pt;">&#160;&#160;</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">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).

be purchased.&#160;The repayment option may only be exercised by the holder of a bond for the principal amount.&#160;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.&#160;This process occurs once per week.&#160;Since the original issuance of these series of bonds in 1995 and 1997, the remarketing agent has successfully remarketed all tendered bonds.&#160;If the remarketing agent is unable to remarket any such bonds, OG&amp;E is obligated to repurchase such unremarketed bonds.&#160;As OG&amp;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

In May 2019, all parties agreed to a settlement which provides for 10 percent base return on equity, plus a 50-basis point adder, and a five-year amortization period of the unprotected excess accumulated deferred income taxes associated with the 2017 Tax Act.

The filing was further amended on May 30, 2019 to include Oklahoma Association of Electric Cooperatives as a settling party. The settlement is subject to OCC approval. Under the terms of the settlement agreement, OG&amp;E would receive full recovery of its environmental investments in the Dry Scrubbers project and in the conversion of Muskogee Units 4 and 5 to natural gas. Base rates would not change as a result of the settlement agreement due to the reduction of costs related to cogeneration contracts and the acceleration of unprotected deferred tax savings over a 10-year period. Further, OG&amp;E's current depreciation rates and return on equity of 9.5 percent for purposes of calculating the allowance for funds used during construction and OG&amp;E's various recovery riders that include a full return component would remain unchanged.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On July 1, 2019, OG&amp;E implemented interim rates, which are subject to refund of any amount recovered in excess of the rates ultimately approved by the OCC in the rate review.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On July 12, 2019, the ALJ issued a report that recommended approval of the settlement agreement and found the settlement agreement fair, just, reasonable and in the public interest. The ALJ's report also recommended that OG&amp;E's environmental compliance decisions and costs related to the Dry Scrubbers project and the conversion of Muskogee Units 4 and 5 to natural gas be found prudent and used and useful with cost recovery allowed. These recommendations are subject to approval by the OCC.

However, SPP had informed participants in the market that these charges would be forthcoming.&#160;In July 2016, the FERC granted SPP's request to recover the charges not billed since 2008. SPP subsequently billed OG&amp;E for these charges and credited OG&amp;E related to transmission upgrades that OG&amp;E had sponsored, which resulted in OG&amp;E being a net receiver of sponsored upgrade credits.</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">The majority of these net credits were refunded to customers through OG&amp;E's various rate riders that include SPP activity with the remaining amounts retained by OG&amp;E.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Several impacted companies sought rehearing of the FERC's July 2016 order; however, in November 2017, the FERC denied the rehearing requests. In January 2018, one of the impacted companies appealed the FERC's decision to the U.S. Court of Appeals for the District of Columbia. In July 2018, the U.S. Court of Appeals for the District of Columbia granted a motion requested by the FERC that the case be remanded back to the FERC for further examination and proceedings. In February 2019, the FERC reversed its July 2016 order and ordered SPP to develop a plan to refund the payments but not to implement the refunds until further ordered to do so. In response, on April 1, 2019, OG&amp;E filed a request for rehearing with the FERC, and on May 24, 2019, OG&amp;E filed a FERC 206 complaint against SPP, alleging SPP's forced unwinding of the revenue credit payments to OG&amp;E would violate the provisions of the Sponsored Upgrade Agreement. OG&amp;E's filing requested that the FERC rule that SPP is not entitled to seek refunds or in any other way seek to unwind the revenue credit payments it had paid to OG&amp;E pursuant to the Sponsored Upgrade Agreement.</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company </span><span style="font-family:inherit;font-size:10pt;">cannot predict the outcome of this proceeding based on currently available information, and as of</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">and at present time,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">has not reserved an amount for a potential refund.

The accounts of the Company and its wholly owned subsidiaries are included in the Condensed Consolidated Financial Statements. All intercompany transactions and balances are eliminated in consolidation. The Company generally uses the equity method of accounting for investments where its ownership interest is between 20 percent and 50 percent and it lacks the power to direct activities that most significantly impact economic performance. </span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The electric utility segment</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas.&#160;Its operations</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are conducted through OG&amp;E and</span><span style="font-family:inherit;font-size:10pt;"> </span><span style="font-family:inherit;font-size:10pt;">are subject to regulation by the OCC, the APSC and the FERC.

Enable was formed in 2013, and its general partner is equally controlled by the Company and CenterPoint, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, the Company accounts for its interest in Enable using the equity method of accounting. Enable is primarily 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 in the Anadarko, Arkoma and Ark-La-Tex Basins. Enable also owns crude oil gathering assets in the Anadarko and Williston Basins. Enable has intrastate natural gas transportation and storage assets that are located in Oklahoma as well as interstate assets that extend from western Oklahoma and the Texas Panhandle to Louisiana, from Louisiana to Illinois and from Louisiana to Alabama.</span></div><span></span>

Enable was formed in 2013, and its general partner is equally controlled by the Company and CenterPoint, who each have 50 percent management ownership. Based on the 50/50 management ownership, with neither company having control, the Company accounts for its interest in Enable using the equity method of accounting. Enable is primarily 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 in the Anadarko, Arkoma and Ark-La-Tex Basins. Enable also owns crude oil gathering assets in the Anadarko and Williston Basins. Enable has intrastate natural gas transportation and storage assets that are located in Oklahoma as well as interstate assets that extend from western Oklahoma and the Texas Panhandle to Louisiana, from Louisiana to Illinois and from Louisiana to Alabama.</span></div><span></span>

If a lease is identified,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">recognizes a right-of-use asset and a lease liability in its</span><span style="font-family:inherit;font-size:10pt;"> Consolidated Balance Sheets. The Company </span><span style="font-family:inherit;font-size:10pt;">recognizes and measures a lease liability when it concludes the contract contains an identified asset that</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">controls through having the right to obtain substantially all of the economic benefits and the right to direct the use of the identified asset. The liability is equal to the present value of lease payments, and the asset is based on the liability, subject to adjustment, such as for initial direct costs. Further,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> utilizes an incremental borrowing rate for purposes of measuring lease liabilities, if the discount rate is not implicit in the lease. To calculate the incremental borrowing rate,</span><span style="font-family:inherit;font-size:10pt;"> the Company</span><span style="font-family:inherit;font-size:10pt;"> starts with a current pricing report for</span><span style="font-family:inherit;font-size:10pt;"> the Company's</span><span style="font-family:inherit;font-size:10pt;"> senior unsecured notes, which indicates rates for periods reflective of the lease term, and adjusts for the effects of collateral to arrive at the secured incremental borrowing rate. As permitted by Topic 842,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">made an accounting policy election to not apply the balance sheet recognition requirements to short-term leases and to not separate lease components from nonlease components when recognizing and measuring lease liabilities. For income statement purposes,</span><span style="font-family:inherit;font-size:10pt;"> the Company </span><span style="font-family:inherit;font-size:10pt;">records operating lease expense on a straight-line basis.</span><span></span>

Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>
