ENTERGY ARKANSAS, LLC - Annual Report: 2007 (Form 10-K)

Entergy is an integrated energy company engaged primarily in electric power production and retail electric distribution operations. Entergy owns and operates power plants with approximately 30,000 MW of electric generating capacity, and Entergy is the second-largest nuclear power generator in the United States. Entergy delivers electricity to 2.7 million utility customers in Arkansas, Louisiana, Mississippi, and Texas. Entergy generated annual revenues of $11.5 billion in 2007 and had approximately 14,300 employees as of December 31, 2007.

Entergy operates primarily through two business segments: Utility and Non-Utility Nuclear.

• Utility generates, transmits, distributes, and sells electric power in a four-state service territory that includes portions of Arkansas, Mississippi, Texas, and Louisiana, including the City of New Orleans; and operates a small natural gas distribution business.
• Non-Utility Nuclear owns and operates six nuclear power plants located in the northern United States and sells the electric power produced by those plants primarily to wholesale customers. This business also provides services to other nuclear power plant owners. As discussed further in "Management's Financial Discussion and Analysis," in November 2007, the Board approved a plan to pursue a separation of the Non-Utility Nuclear business from Entergy through a tax-free spin-off of Non-Utility Nuclear to Entergy shareholders. Entergy is targeting third quarter 2008 as the effective date for the spin-off transaction to be completed.

In addition to its two primary, reportable, operating segments, Entergy also operates the non-nuclear wholesale assets business. The non-nuclear wholesale assets business sells to wholesale customers the electric power produced by power plants that it owns while it focuses on improving performance and exploring sales or restructuring opportunities for its power plants. Such opportunities are evaluated consistent with Entergy's market-based point-of-view.

Entergy management assesses the effectiveness of Entergy's internal control over financial reporting on an annual basis. In making this assessment, management uses the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. Management acknowledges, however, that all internal control systems, no matter how well designed, have inherent limitations and can provide only reasonable assurance with respect to financial statement preparation and presentation.

Entergy operates primarily through two business segments: Utility and Non-Utility Nuclear.

• Utility generates, transmits, distributes, and sells electric power in a four-state service territory that includes portions of Arkansas, Mississippi, Texas, and Louisiana, including the City of New Orleans; and operates a small natural gas distribution business.
• Non-Utility Nuclear owns and operates six nuclear power plants located in the northern United States and sells the electric power produced by those plants primarily to wholesale customers. This business also provides services to other nuclear power plant owners.

In addition to its two primary, reportable, operating segments, Entergy also operates the non-nuclear wholesale assets business. The non-nuclear wholesale assets business sells to wholesale customers the electric power produced by power plants that it owns while it focuses on improving performance and exploring sales or restructuring opportunities for its power plants. Such opportunities are evaluated consistent with Entergy's market-based point-of-view.

Following are the percentages of Entergy's consolidated revenues and net income generated by its operating segments and the percentage of total assets held by them:

In November 2007, the Board approved a plan to pursue a separation of the Non-Utility Nuclear business from Entergy through a tax-free spin-off of Non-Utility Nuclear to Entergy shareholders. SpinCo, the term used to identify the new company that is yet to be named, will be a new, separate, and publicly-traded company. In addition, under the plan, SpinCo and Entergy are expected to enter into a nuclear services business joint venture, with 50% ownership by SpinCo and 50% ownership by Entergy. The nuclear services business board of directors will be comprised of equal membership from both Entergy and SpinCo and may include independent directors.

Upon completion of the spin-off, Entergy Corporation's shareholders will own 100% of the common equity in both SpinCo and Entergy. Entergy expects that SpinCo's business will be substantially comprised of Non-Utility Nuclear's assets, including its six nuclear power plants, and Non-Utility Nuclear's power marketing operation. Entergy Corporation's remaining business will primarily be comprised of the Utility business. The nuclear services business joint venture is expected to operate the nuclear assets owned by SpinCo. The nuclear services business is also expected to offer nuclear services to third parties, including decommissioning, plant relicensing, and plant operation support services, including the services currently provided for the Cooper Nuclear Station in Nebraska.

On January 28, 2008, Entergy Nuclear Vermont Yankee and Entergy Nuclear Operations, Inc. requested approval from the Vermont Public Service Board for the indirect transfer of control, consent to pledge assets, guarantees and assignments of contracts, amendment to certificate of public good to reflect name change, and replacement of guaranty and substitution of a credit support agreement for Vermont Yankee. A prehearing conference scheduled for February 27, 2008 was postponed due to weather.

On January 28, 2008, Entergy Nuclear FitzPatrick, Entergy Nuclear Indian Point 2, Entergy Nuclear Indian Point 3, Entergy Nuclear Operations, and corporate affiliate NewCo (also referred to as SpinCo) filed a petition with the New York Public Service Commission (NYPSC) requesting a declaratory ruling regarding corporate reorganization or in the alternative an order approving the transaction and an order approving debt financing. Petitioners also requested confirmation that the corporate reorganization will not have an effect on Entergy Nuclear FitzPatrick's, Entergy Nuclear Indian Point 2's, Entergy Nuclear Indian Point 3's, and Entergy Nuclear Operations, Inc.' status as lightly regulated entities in New York, given that they will continue to be competitive wholesale generators. The deadline for parties to file comments or request intervention is April 7, 2008.

Pursuant to Federal Power Act Section 203, on February 21, 2008, an application was filed with the FERC requesting approval for the indirect disposition and transfer of control of jurisdictional facilities of a public utility. The review of the filing by FERC will be focused on determining that the transaction will have no adverse effects on competition, wholesale or retail rates and on federal and state regulation. Also, the FERC will seek to determine that the transaction will not result in cross-subsidization by a regulated utility or the pledge or encumbrance of utility assets for the benefit of a non-utility associate company.

Subject to market terms and conditions and pursuant to the plan, SpinCo is expected to execute approximately $4.5 billion of debt financing in connection with the separation. Anticipated uses of the proceeds are for SpinCo to retain $0.5 billion for working capital and for Entergy to retain $4 billion. Entergy expects to use $2.5 billion for share repurchases and $1.5 billion for debt reduction.

Entergy is targeting third quarter 2008 as the effective date for the spin-off and nuclear services business joint venture transactions to be completed. Entergy expects the transactions to qualify for tax-free treatment for U.S. federal income tax purposes for both Entergy and its shareholders. Final terms of the transactions and spin-off completion are subject to several conditions including the final approval of the Board. As Entergy pursues completion of the separation and establishment of the nuclear services business joint venture, Entergy will continue to consider possible modifications to and variations upon the transaction structure, including a sponsored spin-off, a partial initial public offering preceding the spin-off, or the addition of a third-party joint venture partner.

See Note 8 to the financial statements for a discussion of Entergy's conventional property insurance program. Entergy has received a total of $134.5 million as of December 31, 2007 on its Hurricane Katrina and Hurricane Rita insurance claims, including $69.5 million that Entergy received in the second quarter 2007 in settlement of its Hurricane Katrina claim with one of its two excess insurers. In the third quarter 2007, Entergy filed a lawsuit in the U.S. District Court for the Eastern District of Louisiana against its other excess insurer on the Hurricane Katrina claim. At issue in the lawsuit is whether any policy exclusions limit the extent of coverage provided by that insurer.

In March 2006, the Governor of Mississippi signed a law that established a mechanism by which the MPSC could authorize and certify an electric utility financing order and the state could issue bonds to finance the costs of repairing damage caused by Hurricane Katrina to the systems of investor-owned electric utilities.  Because of the passage of this law and the possibility of Entergy Mississippi obtaining CDBG funds for Hurricane Katrina storm restoration costs, in March 2006, the MPSC issued an order approving a Joint Stipulation between Entergy Mississippi and the Mississippi Public Utilities Staff that provided for a review of Entergy Mississippi's total storm restoration costs in an Application for an Accounting Order proceeding.  In June 2006, the MPSC issued an order certifying Entergy Mississippi's Hurricane Katrina restoration costs incurred through March 31, 2006 of $89 million, net of estimated insurance proceeds. Two days later, Entergy Mississippi filed a request with the Mississippi Development Authority for $89 million of CDBG funding for reimbursement of its Hurricane Katrina infrastructure restoration costs. Entergy Mississippi also filed a Petition for Financing Order with the MPSC for authorization of state bond financing of $169 million for Hurricane Katrina restoration costs and future storm costs. The $169 million amount included the $89 million of Hurricane Katrina restoration costs plus $80 million to build Entergy Mississippi's storm damage reserve for the future. Entergy Mississippi's filing stated that the amount actually financed through the state bonds would be net of any CDBG funds that Entergy Mississippi received.

In October 2006, the Mississippi Development Authority approved for payment and Entergy Mississippi received $81 million in CDBG funding for Hurricane Katrina costs. The MPSC then issued a financing order authorizing the issuance of state bonds to finance $8 million of Entergy Mississippi's certified Hurricane Katrina restoration costs and $40 million for an increase in Entergy Mississippi's storm damage reserve. $30 million of the storm damage reserve was set aside in a restricted account. A Mississippi state entity issued the bonds in May 2007, and Entergy Mississippi received proceeds of $48 million. Entergy Mississippi will not report the bonds on its balance sheet because the bonds are the obligation of the state entity, and there is no recourse against Entergy Mississippi in the event of a bond default. To service the bonds, Entergy Mississippi is collecting a system restoration charge on behalf of the state, and will remit the collections to the state. By analogy to and in accordance with Entergy's accounting policy for collection of sales taxes, Entergy Mississippi will not report the collections as revenue because it is merely acting as the billing and collection agent for the state.

Entergy Gulf States Louisiana, Entergy Louisiana, and Entergy Texas have filed with their respective retail regulators for recovery of storm restoration costs, including through securitization. These filings and their results are discussed in Note 2 to the financial statements.

• Entergy New Orleans paid in full, in cash, the allowed third-party prepetition accounts payable (approximately $29 million, including interest). Entergy New Orleans paid interest from September 23, 2005 at the Louisiana judicial rate of interest for 2005 (6%) and 2006 (8%), and at the Louisiana judicial rate of interest plus 1% for 2007 through the date of payment. The Louisiana judicial rate of interest for 2007 is 9.5%.
• Entergy New Orleans issued notes due in three years in satisfaction of its affiliate prepetition accounts payable (approximately $74 million, including interest), including its indebtedness to the Entergy System money pool. Entergy New Orleans included in the principal amount of the notes accrued interest from September 23, 2005 at the Louisiana judicial rate of interest for 2005 (6%) and 2006 (8%), and at the Louisiana judicial rate of interest plus 1% for 2007 through the date of issuance of the notes. Entergy New Orleans will pay interest on the notes from their date of issuance at the Louisiana judicial rate of interest plus 1%. The Louisiana judicial rate of interest is 9.5% for 2007 and 8.5% for 2008.
• Entergy New Orleans repaid in full, in cash, the outstanding borrowings under the debtor-in-possession credit agreement between Entergy New Orleans and Entergy Corporation (approximately $67 million).
• Entergy New Orleans' first mortgage bonds will remain outstanding with their current maturity dates and interest terms. Pursuant to an agreement with its first mortgage bondholders, Entergy New Orleans paid the first mortgage bondholders an amount equal to the one year of interest from the bankruptcy petition date that the bondholders had waived previously in the bankruptcy proceeding (approximately $12 million).
• Entergy New Orleans' preferred stock will remain outstanding on its current dividend terms, and Entergy New Orleans paid its unpaid preferred dividends in arrears (approximately $1 million).
• Litigation claims will generally be unaltered, and will generally proceed as if Entergy New Orleans had not filed for bankruptcy protection, with exceptions for certain claims.

With confirmation of the plan of reorganization, Entergy reconsolidated Entergy New Orleans in the second quarter 2007, retroactive to January 1, 2007. Because Entergy owns all of the common stock of Entergy New Orleans, reconsolidation does not affect the amount of net income that Entergy recorded from Entergy New Orleans' operations for the current or prior periods, but does result in Entergy New Orleans' financial results being included in each individual income statement line item in 2007, rather than only its net income being presented as "Equity in earnings of unconsolidated equity affiliates," as will remain the case for 2005 and 2006.

Following are income statement variances for Utility, Non-Utility Nuclear, Parent & Other business segments, and Entergy comparing 2007 to 2006 showing how much the line item increased or (decreased) in comparison to the prior period:

Refer to "SELECTED FINANCIAL DATA - FIVE-YEAR COMPARISON OF ENTERGY CORPORATION AND SUBSIDIARIES" which accompanies Entergy Corporation's financial statements in this report for further information with respect to operating statistics.

Earnings were negatively affected in the fourth quarter 2007 by expenses of $52 million ($32 million net-of-tax) recorded in connection with a nuclear operations fleet alignment. This process was undertaken with the goals of eliminating redundancies, capturing economies of scale, and clearly establishing organizational governance. Most of the expenses related to the voluntary severance program offered to employees. Approximately 200 employees from the Non-Utility Nuclear business and 150 employees in the Utility business accepted the voluntary severance program offers.

As discussed above, Entergy New Orleans has been reconsolidated retroactive to January 1, 2007 and its results are included in each individual income statement line item for 2007. The variance explanations for the Utility for 2007 compared to 2006 in "Results of Operations" reflect the 2006 results of operations of Entergy New Orleans as if it were reconsolidated in 2006, consistent with the 2007 presentation including the results in each individual income statement line item. Entergy's as-reported results for 2006, which had Entergy New Orleans deconsolidated, and the amounts needed to reconsolidate Entergy New Orleans, which include intercompany items, are set forth in the table below.

10

Utility

Following is an analysis of the change in net revenue comparing 2007 to 2006.

The volume/weather variance resulted primarily from increased electricity usage in the residential and commercial sectors, including increased usage during the unbilled sales period. Billed retail electricity usage increased by a total of 1,591 GWh, an increase of 1.6%. See "MANAGEMENT'S FINANCIAL DISCUSSION AND ANALYSIS - Critical Accounting Estimates" herein and Note 1 to the financial statements for a discussion of the accounting for unbilled revenues.

The base revenues variance resulted from rate increases primarily at Entergy Louisiana effective September 2006 for the 2005 formula rate plan filing to recover LPSC-approved incremental deferred and ongoing purchased power capacity costs. The formula rate plan filing is discussed in Note 2 to the financial statements.

11

The fuel recovery variance is primarily due to the inclusion of Grand Gulf costs in Entergy New Orleans' fuel recoveries effective July 1, 2006. In June 2006, the City Council approved the recovery of Grand Gulf costs through the fuel adjustment clause, without a corresponding change in base rates (a significant portion of Grand Gulf costs was previously recovered through base rates). The increase is also due to purchased power costs deferred at Entergy Louisiana and Entergy New Orleans as a result of the re-pricing, retroactive to 2003, of purchased power agreements among Entergy system companies as directed by the FERC.

The transmission revenue variance is due to higher rates and the addition of new transmission customers in late-2006.

The purchased power capacity variance is due to higher capacity charges and new purchased power contracts that began in mid-2006. A portion of the variance is due to the amortization of deferred capacity costs and is offset in base revenues due to base rate increases implemented to recover incremental deferred and ongoing purchased power capacity charges at Entergy Louisiana, as discussed above.

The net wholesale revenue variance is due primarily to 1) more energy available for resale at Entergy New Orleans in 2006 due to the decrease in retail usage caused by customer losses following Hurricane Katrina and 2) the inclusion in 2006 revenue of sales into the wholesale market of Entergy New Orleans' share of the output of Grand Gulf, pursuant to City Council approval of measures proposed by Entergy New Orleans to address the reduction in Entergy New Orleans' retail customer usage caused by Hurricane Katrina and to provide revenue support for the costs of Entergy New Orleans' share of Grand Gulf. The net wholesale revenue variance is partially offset by the effect of lower wholesale revenues in the third quarter 2006 due to an October 2006 FERC order requiring Entergy Arkansas to make a refund to a coal plant co-owner resulting from a contract dispute.

Non-Utility Nuclear

Net revenue increased for Non-Utility Nuclear from $1,388 million for 2006 to $1,839 million for 2007 primarily due to higher pricing in its contracts to sell power and additional production available resulting from the acquisition of the Palisades plant in April 2007. Amortization of the Palisades purchased power agreement liability, which is discussed in Note 15 to the financial statements, also contributed to the increase. The increase was partially offset by the effect on revenues of four refueling outages in 2007 compared to two in 2006. Following are key performance measures for Non-Utility Nuclear for 2007 and 2006:

Parent & Other

Net revenue decreased for Parent & Other from $114 million for 2006 to $51 million for 2007 primarily due to the sale of the non-nuclear wholesale asset business' remaining interest in a power development project in the second quarter 2006, which resulted in a $14.1 million gain ($8.6 million net-of-tax). Also contributing to the decrease were higher natural gas prices in 2007 compared to the same period in 2006 as well as lower production as a result of an additional plant outage in 2007 compared to the same period in 2006. A substantial portion of the effect on net income of this decline is offset by a related decrease in other operation and maintenance expenses.

12

Utility

Other operation and maintenance expenses increased from $1,749 million for 2006 to $1,855 million for 2007 primarily due to:

• an increase of $34 million in nuclear expenses primarily due to non-refueling outages, increased nuclear labor and contract costs, and higher NRC fees;
• an increase of $21 million related to expenses in the fourth quarter 2007 in connection with the nuclear operations fleet alignment, as discussed above;
• an increase of $20 million in transmission expenses, including independent coordinator of transmission expenses and transmission line and substation maintenance;
• an increase of $16 million as a result of higher insurance premiums in addition to the timing of premium payments compared to 2006;
• an increase of $16 million in fossil plant expenses due to differing outage schedules and scopes from 2006 to 2007 and the return to normal operations work in 2007 versus storm restoration activities in 2006 as a result of Hurricane Katrina;
• an increase of $11 million due to a provision for storm-related bad debts; and
• an increase of $10 million in distribution expenses, including higher contract labor costs, increases in vegetation maintenance costs, and the return to normal operations work in 2007 versus storm restoration activities in 2006 as a result of Hurricane Katrina and Hurricane Rita. This increase is net of an environmental liability credit of $8 million for resolution of a pollution loss provision.

The increase is partially offset by a decrease of $23 million in payroll, payroll-related, and benefits costs.

Depreciation and amortization expenses increased from $835 million for 2006 to $850 million for 2007 primarily due to an increase in plant in service and a revision made in the first quarter 2006 to estimated depreciable lives involving certain intangible assets. The increase was partially offset by a revision in the third quarter 2007 related to depreciation previously recorded on storm-related assets. Recovery of the cost of those assets will now be through the securitization of storm costs approved by the LPSC in the third quarter 2007. The securitization approval is discussed in Note 2 to the financial statements.

Non-Utility Nuclear

Other operation and maintenance expenses increased from $637 million for 2006 to $760 million for 2007 primarily due to the acquisition of the Palisades plant in April 2007 and expenses of $29 million in the fourth quarter 2007 in connection with the nuclear operations fleet alignment.

Other expenses increased due to increases of $14.4 million in nuclear refueling outage expense and $15.7 million in decommissioning expense that resulted almost entirely from the acquisition of Palisades in April 2007.

Parent & Other

Interest charges increased from $101 million for 2006 to $183 million for 2007 primarily due to additional borrowings under Entergy Corporation's revolving credit facilities.

Other income decreased from $93 million for 2006 to $3 million for 2007 primarily due to a gain of approximately $55 million (net-of-tax) in the fourth quarter of 2006 related to the Entergy-Koch investment. 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's 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.

13

The effective income tax rate for 2007 was 30.7%. The reduction in the effective income tax rate versus the federal statutory rate of 35% in 2007 is primarily due to:

• a reduction in income tax expense due to a step-up in the tax basis on the Indian Point 2 non-qualified decommissioning trust fund resulting from restructuring of the trusts, which reduced deferred taxes on the trust fund and reduced current tax expense;
• the resolution of tax audit issues involving the 2002-2003 audit cycle;
• an adjustment to state income taxes for Non-Utility Nuclear to reflect the effect of a change in the methodology of computing New York state income taxes as required by that state's taxing authority;
• book and tax differences related to the allowance for equity funds used during construction; and
• the amortization of investment tax credits.

The effective income tax rate for 2006 was 27.6%. The reduction in the effective income tax rate versus the federal statutory rate of 35% 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's 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 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% to the effective income tax rates, and for additional discussion regarding income taxes.

Following are income statement variances for Utility, Non-Utility Nuclear, Parent & Other business segments, and Entergy comparing 2006 to 2005 showing how much the line item increased or (decreased) in comparison to the prior period:

Following is an analysis of the change in net revenue comparing 2006 to 2005.

The base revenues variance resulted primarily from increases effective October 2005 for Entergy Gulf States Louisiana for the 2004 formula rate plan filing and the annual revenue requirement related to the purchase of power from the Perryville generating station, and increases for Entergy Texas related to an incremental purchased capacity recovery rider that began in December 2005 and a transition to competition rider that began in March 2006. The Attala costs variance is due to the recovery of Attala power plant costs at Entergy Mississippi through the power management rider. The net income effect of the Attala cost recovery is partially offset by Attala costs in other operation and maintenance expenses, depreciation expense, and taxes other than income taxes.

The fuel recovery variance resulted primarily from adjustments of fuel clause recoveries for Entergy Gulf States Louisiana and increased recovery in 2006 of fuel costs from retail and special rate customers.

The pass-through rider revenue variance is due to a change in 2006 in the accounting for city franchise tax revenues in Arkansas as directed by the APSC. The change results in an increase in rider revenue with a corresponding increase in taxes other than income taxes, resulting in no effect on net income.

The transmission revenue variance is primarily due to new transmission customers in 2006. Also contributing to the increase was an increase in rates effective June 2006.

The storm cost recovery variance is due to the return earned on the interim recovery of storm-related costs at Entergy Louisiana and Entergy Gulf States Louisiana in 2006 as allowed by the LPSC. The storm cost recovery filings are discussed in Note 2 to the financial statements.

The volume/weather variance resulted from an increase of 1.7% in electricity usage primarily in the industrial sector. The increase was partially offset by the effect of less favorable weather on billed sales in the residential sector, compared to the same period in 2005, and a decrease in usage during the unbilled period.

The price applied to unbilled sales variance is due to the exclusion in 2006 of the fuel cost component in the calculation of the price applied to unbilled sales. Effective January 1, 2006, the fuel cost component is no longer included in the unbilled revenue calculation at Entergy Louisiana and Entergy Gulf States Louisiana, which is in accordance with regulatory treatment. See "MANAGEMENT'S FINANCIAL DISCUSSION AND ANALYSIS - Critical Accounting Estimates" herein.

15

The purchased power capacity variance is primarily due to higher capacity charges and new purchased power contracts in 2006. A portion of the variance is due to the amortization of deferred capacity costs and is offset in base revenues due to base rate increases implemented to recover incremental deferred and ongoing purchased power capacity charges, as discussed above.

Non-Utility Nuclear

Net revenue increased for Non-Utility Nuclear primarily due to higher pricing in its contracts to sell power. Also contributing to the increase in revenues was increased generation in 2006 due to power uprates completed in 2005 and 2006 at certain plants and fewer refueling outages in 2006. Following are key performance measures for Non-Utility Nuclear for 2006 and 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 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.

16

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's 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 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.

In April 2006, Entergy sold the retail electric portion of the Competitive Retail Services business operating in the 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' 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.

The effective income tax rates for 2006 and 2005 were 27.6% and 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's 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 the 1996-1998 audit cycle. See Note 3 to the financial statements for a reconciliation of the federal statutory rate of 35.0% to the effective income tax rates, and for additional discussion regarding income taxes.

This section discusses Entergy's capital structure, capital spending plans and other uses of capital, sources of capital, and the cash flow activity presented in the cash flow statement.

Entergy's 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's revolving credit facility, along with a decrease in

17

shareholders' equity primarily due to repurchases of common stock. This increase in the debt to capital percentage is in line with Entergy's 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' equity, primarily due to an increase in retained earnings, partially offset by repurchases of common stock.
