pre_text: entergy corporation and subsidiaries management's financial discussion and analysis net revenue utility following is an analysis of the change in net revenue comparing 2011 to 2010 .
amount ( in millions ) .
post_text: the mark-to-market tax settlement sharing variance results from a regulatory charge because a portion of the benefits of a settlement with the irs related to the mark-to-market income tax treatment of power purchase contracts will be shared with customers , slightly offset by the amortization of a portion of that charge beginning in october 2011 .
see notes 3 and 8 to the financial statements for additional discussion of the settlement and benefit sharing .
the purchased power capacity variance is primarily due to price increases for ongoing purchased power capacity and additional capacity purchases .
the net wholesale revenue variance is primarily due to lower margins on co-owner contracts and higher wholesale energy costs .
the volume/weather variance is primarily due to an increase of 2061 gwh in weather-adjusted usage across all sectors .
weather-adjusted residential retail sales growth reflected an increase in the number of customers .
industrial sales growth has continued since the beginning of 2010 .
entergy 2019s service territory has benefited from the national manufacturing economy and exports , as well as industrial facility expansions .
increases have been offset to some extent by declines in the paper , wood products , and pipeline segments .
the increase was also partially offset by the effect of less favorable weather on residential sales .
the ano decommissioning trust variance is primarily related to the deferral of investment gains from the ano 1 and 2 decommissioning trust in 2010 in accordance with regulatory treatment .
the gains resulted in an increase in interest and investment income in 2010 and a corresponding increase in regulatory charges with no effect on net income .
the retail electric price variance is primarily due to : rate actions at entergy texas , including a base rate increase effective august 2010 and an additional increase beginning may 2011 ; a formula rate plan increase at entergy louisiana effective may 2011 ; and a base rate increase at entergy arkansas effective july 2010 .
these were partially offset by formula rate plan decreases at entergy new orleans effective october 2010 and october 2011 .
see note 2 to the financial statements for further discussion of these proceedings. .
