Income taxes are generally allocated to each company in the affiliated group based on its stand-alone taxable income or loss.&amp;#160;&amp;#160;Federal investment tax credits previously claimed on electric utility property have been deferred and are being amortized to income over the life of the related property. The Company continues to amortize its Federal investment tax credits on a ratable basis throughout the year.&amp;#160;&amp;#160;The Company earns both Federal and Oklahoma state tax credits associated with the production from its wind farms as well as earning Oklahoma state tax credits associated with the Company&amp;#8217;s investment in its electric generating facilities which further reduce the Company&amp;#8217;s effective tax rate.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;The Company estimated a Federal tax net operating loss for 2009 primarily caused by the accelerated tax depreciation provisions contained within the American Recovery and Reinvestment Act of 2009 (&amp;#8220;ARRA&amp;#8221;).&amp;#160;&amp;#160;ARRA allowed a current deduction for 50 percent of the cost of certain property placed into service during 2009.&amp;#160;&amp;#160;This tax loss resulted in an approximate $30 million current income tax receivable related to the 2009 tax year.&amp;#160;&amp;#160;On November 6, 2009, the Worker, Homeownership, and Business Assistance Act of 2009 was signed into law by the President.&amp;#160;&amp;#160;This new law provided for a five-year carry back of net operating losses incurred in 2008 or 2009.&amp;#160;&amp;#160;This expanded carryback period enabled the Company to carry back the entire 2009 tax loss. A carryback claim was filed in March 2010 and a refund of approximately $30 million was received by the Company in April 2010.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;In June 2010, new legislation was passed in Oklahoma that creates a moratorium, from July 1, 2010 through June 30, 2012, on approximately 30 income tax credits. For income tax purposes, credits affected by the moratorium may not be claimed for any event, transaction, investment, expenditure or other act for which the credits would otherwise be allowable. During this two-year window, affected credits generated by the Company will be deferred and utilized at a time after the moratorium expires. For financial accounting purposes, the Company will receive the benefits in the future as the credits do not expire if they are not utilized in the period they are generated.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="FONT-STYLE: italic; DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt; FONT-WEIGHT: bold"&gt;Medicare Part D Subsidy&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;On March 23, 2010, the Patient Protection and Affordable Care Act of 2009 (the &amp;#8220;Patient Protection Act&amp;#8221;) was signed into law, and, on March&amp;#160;30, 2010, the Health Care and Education Reconciliation Act of 2010 (the &amp;#8220;Reconciliation Act&amp;#8221; and, together with Patient Protection Act, the &amp;#8220;Acts&amp;#8221;), which makes various amendments to certain aspects of the Patient Protection Act, was signed into law.&amp;#160;&amp;#160;The Acts effectively change the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that provide prescription drug benefits that are at least actuarially equivalent to the corresponding benefits provided under Medicare Part D.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&amp;#160;&lt;/div&gt;&lt;div style="TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;The federal subsidy paid to employers was introduced as part of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the &amp;#8220;Medicare Act&amp;#8221;).&amp;#160;&amp;#160;OGE Energy has been recognizing the federal subsidy since 2005 related to certain retiree prescription drug plans that were determined to be actuarially equivalent to the benefit provided under Medicare Part D. Under the Medicare Act, the federal subsidy does not reduce an employer&amp;#8217;s income tax deduction for the costs of providing such prescription drug plans nor is it subject to income tax individually.&lt;/font&gt;&lt;/div&gt;&lt;div style="TEXT-INDENT: 0pt; DISPLAY: block"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="TEXT-ALIGN: justify; TEXT-INDENT: 36pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt"&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;Under the Acts, beginning in 2013 an employer&amp;#8217;s income tax deduction for the costs of providing Medicare Part D-equivalent prescription drug benefits to retirees will be reduced by the amount of the federal subsidy. Under GAAP, any impact from a change in tax law must be recognized in earnings in the period enacted regardless of the effective date.&amp;#160;&amp;#160;As retiree healthcare liabilities and related tax impacts are already reflected in OGE Energy&amp;#8217;s Condensed Consolidated Financial Statements, OGE Energy recognized a one-time, non-cash charge of approximately $11.4 million during the quarter ended &lt;/font&gt;&lt;font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 12pt"&gt;March&amp;#160;31, 2010 for the write-off of previously recognized tax benefits relating to Medicare Part&amp;#160;D subsidies to reflect the change in the tax treatment of the federal subsidy, of which approximately $7.0 million was the Company&amp;#8217;s portion.&lt;/font&gt;&lt;/div&gt;</NonNumbericText>
