OG&amp;amp;E (Federal Clean Air Act New Source Review Litigation)&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;"&gt;As previously reported, in July 2008, OG&amp;amp;E received a request for information from the EPA regarding Federal Clean Air Act compliance at OG&amp;amp;E's Muskogee and Sooner generating plants.  In recent years, the EPA has issued similar requests to numerous other electric utilities seeking to determine whether various maintenance, repair and replacement projects should have required permits under the Federal Clean Air Act's new source review process.  In January 2012, OG&amp;amp;E received a supplemental request for an update of the previously provided information and for some additional information not previously requested.  On May 1, 2012, OG&amp;amp;E responded to the EPA's supplemental request for information.  On April 26, 2011, the EPA issued a notice of violation alleging that 13 projects occurred at OG&amp;amp;E's Muskogee and Sooner generating plants between 1993 and 2006 without the required new source review permits.  The notice of violation also alleges that OG&amp;amp;E's visible emissions at its Muskogee and Sooner generating plants are not in accordance with applicable new source performance standards.&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;"&gt;In March 2013, the DOJ informed OG&amp;amp;E that it was prepared to initiate enforcement litigation concerning the matters identified in the notice of violation.  OG&amp;amp;E subsequently met with the EPA and DOJ representatives regarding the notice of violation and proposals for resolving the matter without litigation. On July 8, 2013, the United States, at the request of the EPA, filed a complaint for declaratory relief against OG&amp;amp;E in United States District Court for the Western District of Oklahoma (Case No. CIV-13-690-D) alleging that OG&amp;amp;E did not follow the Federal Clean Air Act procedures for projecting emission increases attributable to eight projects that occurred between 2003 and 2006.  This complaint seeks to have OG&amp;amp;E submit a new assessment of whether the projects were likely to result in a significant emissions increase.  OG&amp;amp;E expects to vigorously defend against these claims, but OG&amp;amp;E cannot predict the outcome of such litigation. The Sierra Club, an environmental organization, also has threatened to file a citizen suit under the Federal Clean Air Act alleging similar violations against OG&amp;amp;E, and OG&amp;amp;E expects that the Sierra Club will seek to intervene in the litigation initiated by the EPA. At this time, OG&amp;amp;E continues to believe that it has acted in compliance with the Federal Clean Air Act.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;"&gt;If OG&amp;amp;E does not prevail and if a new assessment of the projects were to conclude that they caused a significant emissions increase, the EPA and the Sierra Club could seek to require OG&amp;amp;E to install additional pollution control equipment, including Dry Scrubbers and selective catalytic reduction systems with capital costs in excess of&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$1.0 billion&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;and pay fines and significant penalties as a result of the allegations in the notice of violation.  Section 113 of the Federal Clean Air Act (along with the Federal Civil Penalties Inflation Adjustment Act of 1996) provides for civil penalties as much as&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;color:#000000;text-decoration:none;"&gt;$37,500&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;per day for each violation.  The cost of any required pollution control equipment could also be significant. OG&amp;amp;E cannot predict at this time whether it will be legally required to incur any of these costs.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;font-style:italic;font-weight:bold;text-decoration:none;"&gt;Other&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;In the normal course of business,&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;
