Rather, street light assets are a separate category of assets, and allowed a 7-year depreciable life. This decision upheld the Utility operating companies’ claim of the shorter depreciable life on their tax returns. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     In September 2010 the U.S. Tax Court held that the U.K. Windfall Tax paid by Entergy when it owned London Electricity can be used as a credit for purposes of computing the U.S. foreign tax credit. Entergy claimed this credit and established a provision for uncertain tax positions on the issue. With the receipt of the favorable Tax Court decision, Entergy reversed the $43 million provision. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><u><b>Income Tax Audits</b></u> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt"><b>2002-2003 IRS Audit</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Because of the favorable Tax Court decisions discussed above in <u><b>Income Tax Litigation</b></u>, Entergy and the Utility operating companies no longer expect to receive a Notice of Deficiency from the IRS for the 2002 and 2003 tax years. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><u><b>Other Tax Matters</b></u> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Entergy and the Registrant Subsidiaries do not expect that total amounts of unrecognized tax benefits will significantly increase or decrease within the next 12 months resulting from litigation and audit proceedings. Entergy regularly pursues settlements, however, that could result in adjustments to the total amounts of unrecognized tax benefits. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire income tax disclosure.
