Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory commissions, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report. Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein. ANO Damage, Outage, and NRC Reviews See Note 8 to the financial statements in the Form 10-K for a discussion of the ANO stator incident and subsequent NRC reviews. As discussed in the Form 10-K, in January 2015 the NRC issued its final risk significance determination for the flood barrier violation originally cited in the September 2014 report. The NRC’s final risk significance determination was classified as “yellow with substantial safety significance.” In March 2015 the NRC issued a letter notifying Entergy of its decision to move ANO into the “multiple/repetitive degraded cornerstone column” (Column 4) of the NRC’s Reactor Oversight Process Action Matrix. Placement into Column 4 will require significant additional NRC inspection activities at the ANO site, including a review of the site’s root cause evaluation associated with the flood barrier and stator issues, an assessment of the effectiveness of the site’s corrective action program, an additional design basis inspection, a safety culture assessment, and possibly other inspection activities consistent with the NRC’s Inspection Procedure. Excluding remediation and response costs that may result from the additional NRC inspection activities, Entergy Arkansas expects to incur incremental costs of approximately $50 million in 2015, of which $38 million had been incurred as of September 30, 2015, and approximately $35 million in 2016 to prepare for the NRC inspection expected to occur in early 2016. Baxter Wilson Plant Event See Note 8 to the financial statements in the Form 10-K for a discussion of the Baxter Wilson plant event. Entergy Mississippi received all $28.2 million of its previously-accrued insurance proceeds, with $12.9 million allocated to capital spending and $15.3 million allocated to operation and maintenance expenses. Pilgrim NRC Oversight and Planned Shutdown In September 2015 the NRC placed Pilgrim in its “multiple/repetitive degraded cornerstone column” (Column 4) of its Reactor Oversight Process Action Matrix due to its finding of continuing weaknesses in Pilgrim’s corrective action program that contributed to repeated unscheduled shutdowns and equipment failures. The preliminary estimate of direct costs of Pilgrim’s response to a planned NRC enhanced inspection ranges from $45 million to $60 million in operation and maintenance expense, not including any potential capital investment or other costs to address issues that may arise in the inspection. Entergy determined in October 2015 that it will close Pilgrim, no later than June 1, 2019, because of poor market conditions, reduced revenues, and increased operational costs. Pilgrim currently has approximately 677 MW of Capacity Supply Obligations in ISO New England through May 2019. If Pilgrim shuts down earlier than June 2019 it could have to buy back its Capacity Supply Obligations at prices higher than the capacity rates Pilgrim is currently scheduled to receive. The precise timing of the shutdown depends on several factors, including further discussion with ISO New England. Management expects the timing of the shutdown will be decided in the first half of 2016. See Note 11 to the financial statements herein for discussion of the impairment of the value of Pilgrim as of September 30, 2015. Nuclear Fuel Enrichment Contracts Entergy subsidiaries are parties to two contracts with American Centrifuge Enrichment, LLC (ACE) under which these subsidiaries purchase nuclear fuel enrichment services. The term of each contract is from 2011 to 2022; however, each contract provided for cancellation of the parties’ purchase and sale obligations for 2016-2022 if, by August 1, 2014, ACE’s planned Advanced Centrifuge Plant was not in commercial operation and ACE did not identify to Entergy’s reasonable satisfaction how it would meet its contractual delivery obligations through output from ACE. In August 2014, Entergy sent notice to ACE that the 2016-2022 obligations were canceled by the operation of this contractual provision. United States Enrichment Corporation (USEC), ACE’s affiliate to which ACE assigned the contracts, filed a demand for arbitration with the American Arbitration Association, claiming damages of approximately $165 million. In July 2015 the parties reached an agreement resolving the dispute that resulted in the dismissal of USEC’s claims. The resolution of the dispute does not have a material effect on Entergy’s results of operations, financial position, or cash flows. Nuclear Insurance See Note 8 to the financial statements in the Form 10-K for information on nuclear liability and property insurance associated with Entergy’s nuclear power plants. Conventional Property Insurance See Note 8 to the financial statements in the Form 10-K for information on Entergy’s non-nuclear property insurance program. Employment Litigation See Note 8 to the financial statements in the Form 10-K for information on Entergy’s employment and labor-related proceedings. Asbestos Litigation (Entergy Louisiana, Entergy New Orleans, and Entergy Texas) See Note 8 to the financial statements in the Form 10-K for information regarding asbestos litigation at Entergy Gulf States Louisiana, Entergy Louisiana, Entergy New Orleans, and Entergy Texas.

Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) Entergy and the Registrant Subsidiaries are involved in a number of legal, regulatory, and tax proceedings before various courts, regulatory commissions, and governmental agencies in the ordinary course of business. While management is unable to predict with certainty the outcome of such proceedings, management does not believe that the ultimate resolution of these matters will have a material adverse effect on Entergy’s results of operations, cash flows, or financial condition, except as otherwise discussed in the Form 10-K or in this report. Entergy discusses regulatory proceedings in Note 2 to the financial statements in the Form 10-K and herein and discusses tax proceedings in Note 3 to the financial statements in the Form 10-K and Note 10 to the financial statements herein. ANO Damage, Outage, and NRC Reviews See Note 8 to the financial statements in the Form 10-K for a discussion of the ANO stator incident and subsequent NRC reviews. As discussed in the Form 10-K, in January 2015 the NRC issued its final risk significance determination for the flood barrier violation originally cited in the September 2014 report. The NRC’s final risk significance determination was classified as “yellow with substantial safety significance.” In March 2015 the NRC issued a letter notifying Entergy of its decision to move ANO into the “multiple/repetitive degraded cornerstone column” (Column 4) of the NRC’s Reactor Oversight Process Action Matrix. Placement into Column 4 will require significant additional NRC inspection activities at the ANO site, including a review of the site’s root cause evaluation associated with the flood barrier and stator issues, an assessment of the effectiveness of the site’s corrective action program, an additional design basis inspection, a safety culture assessment, and possibly other inspection activities consistent with the NRC’s Inspection Procedure. Excluding remediation and response costs that may result from the additional NRC inspection activities, Entergy Arkansas expects to incur incremental costs of approximately $50 million in 2015, of which $38 million had been incurred as of September 30, 2015, and approximately $35 million in 2016 to prepare for the NRC inspection expected to occur in early 2016. Baxter Wilson Plant Event See Note 8 to the financial statements in the Form 10-K for a discussion of the Baxter Wilson plant event. Entergy Mississippi received all $28.2 million of its previously-accrued insurance proceeds, with $12.9 million allocated to capital spending and $15.3 million allocated to operation and maintenance expenses. Pilgrim NRC Oversight and Planned Shutdown In September 2015 the NRC placed Pilgrim in its “multiple/repetitive degraded cornerstone column” (Column 4) of its Reactor Oversight Process Action Matrix due to its finding of continuing weaknesses in Pilgrim’s corrective action program that contributed to repeated unscheduled shutdowns and equipment failures. The preliminary estimate of direct costs of Pilgrim’s response to a planned NRC enhanced inspection ranges from $45 million to $60 million in operation and maintenance expense, not including any potential capital investment or other costs to address issues that may arise in the inspection. Entergy determined in October 2015 that it will close Pilgrim, no later than June 1, 2019, because of poor market conditions, reduced revenues, and increased operational costs. Pilgrim currently has approximately 677 MW of Capacity Supply Obligations in ISO New England through May 2019. If Pilgrim shuts down earlier than June 2019 it could have to buy back its Capacity Supply Obligations at prices higher than the capacity rates Pilgrim is currently scheduled to receive. The precise timing of the shutdown depends on several factors, including further discussion with ISO New England. Management expects the timing of the shutdown will be decided in the first half of 2016. See Note 11 to the financial statements herein for discussion of the impairment of the value of Pilgrim as of September 30, 2015. Nuclear Fuel Enrichment Contracts Entergy subsidiaries are parties to two contracts with American Centrifuge Enrichment, LLC (ACE) under which these subsidiaries purchase nuclear fuel enrichment services. The term of each contract is from 2011 to 2022; however, each contract provided for cancellation of the parties’ purchase and sale obligations for 2016-2022 if, by August 1, 2014, ACE’s planned Advanced Centrifuge Plant was not in commercial operation and ACE did not identify to Entergy’s reasonable satisfaction how it would meet its contractual delivery obligations through output from ACE. In August 2014, Entergy sent notice to ACE that the 2016-2022 obligations were canceled by the operation of this contractual provision. United States Enrichment Corporation (USEC), ACE’s affiliate to which ACE assigned the contracts, filed a demand for arbitration with the American Arbitration Association, claiming damages of approximately $165 million. In July 2015 the parties reached an agreement resolving the dispute that resulted in the dismissal of USEC’s claims. The resolution of the dispute does not have a material effect on Entergy’s results of operations, financial position, or cash flows.
