timely manner.\t15\n0\tOG&E's rates are subject to various regulatory agencies whose regulatory paradigms and goals may differ.\t15\n0\tCosts of compliance with environmental laws and regulations are significant and may increase with the new Biden administration.\t16\n0\tCosts of the Registrants' investments in capital improvements and additions may not be recoverable.\t16\n0\tThe regional power market in which OG&E operates has changing transmission regulatory structures.\t16\n0\tThe Registrants may face increased competition resulting from changes to the utility and energy markets.\t17\n0\tThe Registrants are subject to compliance with substantial utility and energy regulation.\t17\nOperational Risks\t\t\n0\tResults of operations may be impacted by disruptions to the Registrants' fuel supply or the electric grid that are beyond the Registrants' control.\t17\n0\tOG&E's electric assets are subject to various operational risks including outages and accidents.\t17\n0\tChanges in technology regulatory policies and customer electricity consumption may cause the Registrants' assets to be less competitive.\t18\n0\tThe Registrants may be impacted by severe weather conditions as well as seasonal temperature variations.\t18\nFinancial Risks\t\t\n0\tThe Registrants may be impacted by changes related to their Pension Plan and health care plans including market performance increased retirements change in regulations and increasing costs.\t18\n0\tOGE Energy is a holding company with its primary assets being investments in other companies.\t19\nRisks Associated with OGE Energy's Investment in Enable\t\t\n0\tOGE Energy does not control Enable and therefore cannot cause or prevent certain actions by Enable.\t19\n0\tOGE Energy's operating cash flow is derived partially from cash distributions received from Enable.\t20\n0\tEnable's contracts are subject to renewal risks.\t20\n0\tEnable's businesses are dependent in part on the drilling and production decisions of others which are impacted by demand and commodity prices.\t21\n0\tEnable's industry is highly competitive.\t22\n", "q10k_tbl_4": "0\tNatural gas NGLs and crude prices are volatile.\t22\n0\tA pandemic epidemic or outbreak of an infectious disease may materially adversely affect Enable's business.\t22\n0\tEnable has contracts that provide services under fixed prices which could result in costs exceeding revenues.\t23\n0\tIf third-party facilities that interconnect with Enable's facilities are unavailable Enable may be impacted.\t23\n0\tEnable does not own all of the land on which its facilities are located which could disrupt its operations.\t24\n0\tAn impairment of long-lived assets could reduce Enable's earnings.\t24\n0\tEnable's business involves hazards and operational risks some of which may not be fully covered by insurance.\t24\n0\tThe use of derivative contracts could result in financial losses.\t25\n0\tFailure to attract and retain an appropriately qualified workforce could adversely impact Enable.\t25\n0\tCybersecurity attacks or other disruptions to Enable's systems and networks could have adverse impacts.\t25\n0\tTerrorist attacks or other physical threats could adversely affect Enable's business.\t26\n0\tIf Enable fails to maintain effective internal controls reported financial results could be affected.\t26\n0\tEnable is dependent on a small number of customers for a significant portion of its revenues.\t26\n0\tEnable is exposed to the credit risk of its customers.\t26\n0\tEnable's debt levels may limit its flexibility in obtaining additional financing or pursuing business opportunities.\t26\n0\tEnable's credit facilities contain restrictions that may be affected by events beyond its control.\t27\n0\tAny reductions in Enable's credit ratings could increase financing costs.\t27\n0\tEnable may not be able to recover the costs of substantial planned investment in capital improvements.\t28\n0\tEnable's ability to grow is dependent in part on its access to external financing sources on acceptable terms.\t28\n0\tEnable's merger and acquisition activities may not be successful.\t29\n0\tEnable may be unable to obtain or renew permits necessary for its operations.\t29\n0\tEnable's operations may be impacted by certain indigenous rights protections.\t29\n0\tCosts of compliance with environmental laws and regulations are significant.\t30\n0\tIncreased regulation of hydraulic fracturing could result in reductions or delays in natural gas production by Enable's customers.\t30\n0\tEnable and its customers' operations are subject to risks related to the threat of climate change.\t31\n0\tEnable's operations are subject to extensive federal regulations.\t32\n0\tEnable's operations are subject to state and local regulations.\t34\n0\tA change in jurisdictional characterization of Enable's assets by regulators could result in increased regulation.\t34\n0\tEnable may incur significant costs related to compliance with pipeline safety laws and regulations.\t34\n0\tThe Dodd-Frank Act regulations could affect Enable's ability to hedge risks associated with its business.\t35\n0\tEnable derives a substantial portion of its gross margin from subsidiaries.\t36\n0\tEnable conducts a portion of its operations through joint ventures which subjects them to additional risks.\t36\n0\tUnder certain circumstances Enbridge Inc. could have the right to purchase an ownership interest in SESH.\t36\n0\tThe amount of cash Enable has available for distribution depends on cash flow rather than profitability.\t37\n0\tAffiliates of Enable's general partner may compete with Enable.\t37\n0\tEnable may issue additional units without unitholder approval which could dilute existing ownership.\t38\n0\tAffiliates of Enable's general partner may sell common units which could impact the trading price of units.\t38\n0\tEnable's Series A Preferred Units have rights and privileges that are preferential to those of common units.\t38\n0\tEnable's Series A Preferred Units contain covenants that may limit business flexibility.\t39\n0\tEnable's Series A Preferred units are required to be redeemed in certain circumstances.\t39\n0\tEnable's unitholders cannot be certain of the precise value of any Energy Transfer merger consideration they may receive.\t39\n0\tThe Energy Transfer merger may not be completed and the merger agreement may be terminated.\t39\n0\tThe Energy Transfer merger agreement limits Enable's ability to pursue alternatives to the merger.\t40\n0\tFailure to complete the Energy Transfer merger could negatively impact Enable's future financial results.\t40\n0\tEnable will be subject to business uncertainties while the merger is pending.\t40\n", "q10k_tbl_5":

merger.\t41\n0\tEnable may be a target of securities class action and derivative lawsuits as a result of the Energy Transfer merger.\t41\nGeneral Risks\t\t\n0\tEvents that are beyond the Registrants' control have increased public and regulatory scrutiny of their industry.\t41\n0\tEconomic conditions could negatively impact the Registrants' business.\t42\n0\tThe Registrants are subject to financial risks associated with climate change.\t42\n0\tThe Registrants are subject to cybersecurity risks and increased reliance on processes automated by technology.\t42\n0\tTerrorist attacks and the threat of terrorist attacks have increased costs to the Registrants' business.\t43\n0\tThe Registrants face risks related to health epidemics and other outbreaks.\t43\n0\tThe Registrants face risks related to the availability of trained and qualified labor to meet their staffing requirements.\t44\n0\tCertain provisions in the Registrants' charter documents have anti-takeover effects.\t44\n0\tThe

Information\"\tThis standard requires entities to measure all expected credit losses of financial assets held at a reporting date based on historical experience current conditions and reasonable and supportable forecasts in order to record credit losses in a more timely manner.\tJanuary 1 2020\tUtilizing a modified-retrospective approach the Registrants determined their only financial instrument requiring measurement under ASU 2016-13 is trade receivables. The Registrants consider both future economic conditions and historical data to measure their reserves for trade receivables under this standard and determined no adjustments to their reserves were necessary upon adoption.\nASU 2018-15 \"Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)\"\tThe standard aligns requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software.\tJanuary 1 2020\tThe new standard did not have a material effect on the Registrants' financial statements upon adoption. Prospectively the Registrants record applicable capitalized implementation costs in Other Current Assets in the balance sheets and related amortization expense in Other Operation and Maintenance in the statements of income.\nASU 2018-13 \"Fair Value Measurement (Topic 820): Disclosure Framework\"\tThe standard removes adds or modifies disclosure requirements that impact all levels of the fair value hierarchy as well as investments measured using the net asset value practical expedient.\tJanuary 1 2020\tThe Registrants applied the guidance on a retrospective or prospective basis depending on the requirement and did not experience a significant impact on their financial statement disclosures.\nASU 2018-14 \"Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)\"\tThe standard removes adds or clarifies disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans.\tJanuary 1 2020\tThe Registrants applied the guidance on a retrospective basis and did not experience a significant impact on their financial statement disclosures.\nASU 2020-04 \"Reference Rate Reform (Topic 848)\"\tThis standard provides optional expedients and exceptions if certain criteria are met for applying GAAP to contracts hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform.\tJanuary 1 2020\tThe guidance did not have a material impact upon adoption nor do the Registrants expect a material impact in the future on their

OGE Energy, incorporated in August 1995 in the State of Oklahoma, is a holding company with investments in energy and energy services providers offering physical delivery and related services for both electricity and natural gas primarily in the south central U.S. OGE Energy conducts these activities through two business segments: (i) electric utility and (ii) natural gas midstream operations.
OG&E. OGE Energy's electric utility operations are conducted through OG&E, which generates, transmits, distributes and sells electric energy in Oklahoma and western Arkansas. OG&E's rates are subject to regulation by the OCC, the APSC and the FERC. OG&E was incorporated in 1902 under the laws of the Oklahoma Territory and is a wholly-owned subsidiary of OGE Energy. OG&E is the largest electric utility in Oklahoma, and its franchised service territory includes Fort Smith, Arkansas and the surrounding communities. OG&E sold its retail natural gas business in 1928 and is no longer engaged in the natural gas distribution business.
Enable. OGE Energy's natural gas midstream operations segment represents OGE Energy's investment in Enable. The investment in Enable is held through wholly-owned subsidiaries and ultimately OGE Holdings. 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. AtDecember 31, 2020, OGE Energy owned 111.0 million common units, or 25.5 percent, of Enable's outstanding common units.
On February 16, 2021, Enable entered into a definitive merger agreement with Energy Transfer, pursuant to which, and subject to the conditions of the merger agreement, all outstanding common units of Enable will be acquired by Energy Transfer in an all-equity transaction. Under the terms of the merger agreement, Enable's common unitholders, including OGE Energy, will receive 0.8595 of one common unit representing limited partner interests in Energy Transfer for each common unit of Enable. The transaction is anticipated to close in 2021. The transaction is subject to the receipt of the required approvals from the holders of a majority of Enable's common units, anti-trust approvals and other customary closing conditions. Assuming the transaction closes, OGE Energy will own approximately three percent of Energy Transfer's outstanding limited partner units in lieu of the 25.5 percent interest in Enable that it currently owns. Energy Transfer owns and operates one of the largest and most diversified portfolios of energy assets in the U.S., with a strategic footprint in all of the major domestic production basins. Energy Transfer is a publicly traded limited partnership with core operations that include complementary natural gas midstream, intrastate and interstate transportation and storage assets; crude oil, NGL and refined product transportation and terminalling assets; NGL fractionation; and various acquisition and marketing assets.
See "Enable's Pending Merger with Energy Transfer" within "Item 1A. Risk Factors" for a discussion of risks related to the Enable and Energy Transfer merger.

•leading economic development and job growth by attracting new and diverse businesses to improve the infrastructure of the communities in Oklahoma and Arkansas;
•ensuring the necessary mix of generation resources to meet the long-term capacity needs of our customers, with a progressively cleaner generation portfolio;
•continuing focus on innovation, intellectual curiosity and executing with excellence in order to maintain customer rates that are some of the most affordable in the country;
•delivering on earnings commitments to shareholders to enhance access to lower-cost debt and equity capital that is needed to deploy infrastructure for the long-term economic health of its communities;

•developing and growing our members to be able to provide a greater contribution to the company's success, while also improving their own lives.
OGE Energy is focused on creating long-term shareholder value by targeting the consistent growth of earnings per share of five percent at the electric utility, underscored by a strategy of investing in lower risk infrastructure projects that improve the economic vitality of the communities it serves in Oklahoma and Arkansas. OGE Energy utilizes cash distributions from its natural gas midstream operations segment to help fund its electric utility capital investments. OGE Energy's financial objectives also include maintaining investment grade credit ratings and providing a strong and reliable dividend for shareholders.
OGE Energy's long-term sustainability is predicated on providing exceptional customer experiences, investing in grid improvements and increasingly cleaner generation resources, environmental stewardship, strong governance practices and caring for and supporting its members and communities.
Electric Operations - OG&E
General
OG&E furnishes retail electric service in 267 communities and their contiguous rural and suburban areas. The service area covers 30,000 square miles in Oklahoma and western Arkansas, including Oklahoma City, the largest city in Oklahoma, and Fort Smith, Arkansas, the second largest city in that state. Of the 267 communities that OG&E serves, 241 are located in Oklahoma, and 26 are in Arkansas. OG&E derived 92 percent of its total electric operating revenues in 2020 from sales in Oklahoma and the remainder from sales in Arkansas. OG&E does not currently serve wholesale customers in either state.
OG&E's system control area peak demand in 2020 was 6,437 MWs on August 28, 2020. OG&E's load responsibility peak demand was 5,711 MWs on August 28, 2020. The following table presents system sales and variations in system sales for 2020, 2019 and 2018.

OG&E is subject to competition in various degrees from government-owned electric systems, municipally-owned electric systems, rural electric cooperatives and, in certain respects, from other private utilities, power marketers and cogenerators. Oklahoma law forbids the granting of an exclusive franchise to a utility for providing electricity.
6
Besides competition from other suppliers or marketers of electricity, OG&E competes with suppliers of other forms of energy. The degree of competition between suppliers may vary depending on relative costs and supplies of other forms of energy. It is possible that changes in regulatory policies or advances in technologies such as fuel cells, microturbines, windmills and photovoltaic solar cells will reduce costs of new technology to levels that are equal to or below that of most central station electricity production. OG&E's ability to maintain relatively low cost, efficient and reliable operations is a significant determinant of its competitiveness.

Regulation and Rates
OG&E's retail electric tariffs are regulated by the OCC in Oklahoma and by the APSC in Arkansas. The issuance of certain securities by OG&E is also regulated by the OCC and the APSC. OG&E's transmission activities, short-term borrowing authorization and accounting practices are subject to the jurisdiction of the FERC. The Secretary of the U.S. Department of Energy has jurisdiction over some of OG&E's facilities and operations. In 2020, 86 percent of OG&E's electric revenue was subject to the jurisdiction of the OCC, eight percent to the APSC and six percent to the FERC.
The OCC and the APSC require that, among other things, (i) OGE Energy permits the OCC and the APSC access to the books and records of OGE Energy and its affiliates relating to transactions with OG&E; (ii) OGE Energy employ accounting and other procedures and controls to protect against subsidization of non-utility activities by OG&E's customers; and (iii) OGE Energy refrain from pledging OG&E assets or income for affiliate transactions. In addition, the FERC has access to the books and records of OGE Energy and its affiliates as the FERC deems relevant to costs incurred by OG&E or necessary or appropriate for the protection of utility customers with respect to the FERC jurisdictional rates.
For information concerning OG&E's recently completed and currently pending regulatory proceedings, see Note 16 within "Item 8. Financial Statements and Supplementary Data."
Regulatory Assets and Liabilities
OG&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. Likewise, certain actual or anticipated credits that would otherwise reduce expense can be deferred as regulatory liabilities, based on the expected flowback to customers in future rates. Management's expected recovery of deferred costs and flowback of deferred credits generally results from specific decisions by regulators granting such ratemaking treatment.
OG&E records certain incurred costs and obligations as regulatory assets or liabilities if, based on regulatory orders or other available evidence, it is probable that the costs or obligations will be included in amounts allowable for recovery or refund in future rates. Management continuously monitors the future recoverability of regulatory assets. When in management's judgment future recovery becomes impaired, the amount of the regulatory asset is adjusted, as appropriate. If OG&E were required to discontinue the application of accounting principles for certain types of rate-regulated activities for some or all of its operations, it could result in writing off the related regulatory assets or liabilities, which could have significant financial effects. See Note 1 within "Item 8. Financial Statements and Supplementary Data" for further discussion of OG&E's regulatory assets and liabilities.
Rate Structures
Oklahoma
OG&E's standard tariff rates include a cost of service component (including an authorized return on capital) plus a fuel adjustment clause mechanism that allows OG&E to pass through to customers the actual cost of fuel and purchased power.
OG&E offers several alternative customer programs and rate options, as described below.
•Under OG&E's Smart Grid-enabled SmartHours programs, "time-of-use" and "variable peak pricing" rates offer customers the ability to save on their electricity bills by shifting some of the electricity consumption to off-peak times when demand for electricity is lowest.
•The guaranteed flat bill option for residential and small general service accounts allows qualifying customers the opportunity to purchase their electricity needs at a set monthly price for an entire year.
•The Renewable Energy Credit purchase program, a rate option that provides a "renewable energy" resource, is available as a voluntary option to all of OG&E's Oklahoma retail customers. OG&E's ownership and access to wind and solar resources makes the renewable option a possible choice in meeting the renewable energy needs of OG&E's conservation-minded customers.
•Load Reduction is a voluntary load curtailment program that provides OG&E's commercial and industrial customers with the opportunity to curtail usage on a voluntary basis when OG&E's system conditions merit curtailment action. Customers that curtail their usage will receive payment for their curtailment response. This voluntary curtailment program seeks customers that can curtail on most curtailment event days but may not be able to curtail every time that a curtailment event is required.

•OG&E offers certain qualifying customers "day-ahead price" and "flex price" rate options which allow participating customers to adjust their electricity consumption based on price signals received from OG&E. The prices for the "day-ahead price" and "flex price" rate options are based on OG&E's projected next day hourly operating costs.
OG&E has Public Schools-Demand and Public Schools Non-Demand rate classes that provide OG&E with flexibility to provide targeted programs for load management to public schools and their unique usage patterns. OG&E also provides service level, seasonal and time period fuel charge differentiation that allows customers to pay fuel costs that better reflect the underlying costs of providing electric service. Lastly, OG&E has a military base rider that demonstrates Oklahoma's continued commitment to our military partners.
The previously discussed rate options, coupled with OG&E's other rate choices, provide many tariff options for OG&E's Oklahoma retail customers. The revenue impacts associated with these options are not determinable in future years because customers may choose to remain on existing rate options instead of volunteering for the alternative rate option choices. Revenue variations may occur in the future based upon changes in customers' usage characteristics if they choose alternative rate options.
Arkansas
OG&E's standard tariff rates include a cost of service component (including an authorized return on capital) plus an energy cost recovery mechanism that allows OG&E to pass through to customers the actual cost of fuel and purchased power. OG&E's current rate order from the APSC includes a formula rate rider that provides for an annual adjustment to rates if the earned rate of return falls outside of a plus or minus 50 basis point dead-band around the allowed return on equity. Adjustments are limited to plus or minus four percent of revenue for each rate class for the 12 months preceding the test period. The initial term for the formula rate rider is not to exceed five years from the date of the APSC final order in the last general rate review, May 18, 2017, unless additional approval is obtained from the APSC.
