the perryville plant coming online in july 2005 ; n an increase of $ 12 million related to storm reserves . this increase does not include costs associated with hurricanes katrina and rita ; and n an increase of $ 12 million due to a return to normal expense patterns in 2006 versus the deferral or capitalization of storm costs in 2005 . other operation and maintenance expenses increased for non- utility nuclear from $ 588 million in 2005 to $ 637 million in 2006 primarily due to the timing of refueling outages , increased benefit and insurance costs , and increased nrc fees . taxes other than income taxes taxes other than income taxes increased for the utility from $ 322 million in 2005 to $ 361 million in 2006 primarily due to an increase in city franchise taxes in arkansas due to a change in 2006 in the accounting for city franchise tax revenues as directed by the apsc . the change results in an increase in taxes other than income taxes with a corresponding increase in rider revenue , resulting in no effect on net income . also contributing to the increase was higher franchise tax expense at entergy gulf states , inc . as a result of higher gross revenues in 2006 and a customer refund in 2005 . other income other income increased for the utility from $ 111 million in 2005 to $ 156 million in 2006 primarily due to carrying charges recorded on storm restoration costs . other income increased for non-utility nuclear primarily due to miscellaneous income of $ 27 million ( $ 16.6 million net-of-tax ) resulting from a reduction in the decommissioning liability for a plant as a result of a revised decommissioning cost study and changes in assumptions regarding the timing of when decommissioning of a plant will begin . other income increased for parent & other primarily due to a gain related to its entergy-koch investment of approximately $ 55 million ( net-of-tax ) in the fourth quarter of 2006 . in 2004 , entergy-koch sold its energy trading and pipeline businesses to third parties . at that time , entergy received $ 862 million of the sales proceeds in the form of a cash distribution by entergy-koch . due to the november 2006 expiration of contingencies on the sale of entergy-koch 2019s trading business , and the corresponding release to entergy-koch of sales proceeds held in escrow , entergy received additional cash distributions of approximately $ 163 million during the fourth quarter of 2006 and recorded a gain of approximately $ 55 million ( net-of-tax ) . entergy expects future cash distributions upon liquidation of the partnership will be less than $ 35 million . interest charges interest charges increased for the utility and parent & other primarily due to additional borrowing to fund the significant storm restoration costs associated with hurricanes katrina and rita . discontinued operations in april 2006 , entergy sold the retail electric portion of the competitive retail services business operating in the electric reliability council of texas ( ercot ) region of texas , and now reports this portion of the business as a discontinued operation . earnings for 2005 were negatively affected by $ 44.8 million ( net-of-tax ) of discontinued operations due to the planned sale . this amount includes a net charge of $ 25.8 million ( net-of-tax ) related to the impairment reserve for the remaining net book value of the competitive retail services business 2019 information technology systems . results for 2006 include an $ 11.1 million gain ( net-of-tax ) on the sale of the retail electric portion of the competitive retail services business operating in the ercot region of texas . income taxes the effective income tax rates for 2006 and 2005 were 27.6% ( 27.6 % ) and 36.6% ( 36.6 % ) , respectively . the lower effective income tax rate in 2006 is primarily due to tax benefits , net of reserves , resulting from the tax capital loss recognized in connection with the liquidation of entergy power international holdings , entergy 2019s holding company for entergy-koch . also contributing to the lower rate for 2006 is an irs audit settlement that allowed entergy to release from its tax reserves all settled issues relating to 1996-1998 audit cycle . see note 3 to the financial statements for a reconciliation of the federal statutory rate of 35.0% ( 35.0 % ) to the effective income tax rates , and for additional discussion regarding income taxes . liquidity and capital resources this section discusses entergy 2019s capital structure , capital spending plans and other uses of capital , sources of capital , and the cash flow activity presented in the cash flow statement . capital structure entergy 2019s capitalization is balanced between equity and debt , as shown in the following table . the increase in the debt to capital percentage from 2006 to 2007 is primarily the result of additional borrowings under entergy corporation 2019s revolving credit facility , along with a decrease in shareholders 2019 equity primarily due to repurchases of common stock . this increase in the debt to capital percentage is in line with entergy 2019s financial and risk management aspirations . the decrease in the debt to capital percentage from 2005 to 2006 is the result of an increase in shareholders 2019 equity , primarily due to an increase in retained earnings , partially offset by repurchases of common stock. .
