 and SubsidiariesManagement’s Financial Discussion and Analysis

inspection program and performance indicators reported by the licensee.  The evaluations result in the placement of each plant in one of the NRC’s Reactor Oversight Process Action Matrix columns: “licensee response column,” or Column 1, “regulatory response column,” or Column 2, “degraded cornerstone column,” or Column 3, “multiple/repetitive degraded cornerstone column,” or Column 4, and “unacceptable performance,” or Column 5.  Plants in Column 1 are subject to normal NRC inspection activities.  Plants in Column 2, Column 3, or Column 4 are subject to progressively increasing levels of inspection by the NRC with, in general, progressively increasing levels of associated costs.  Continued plant operation is not permitted for plants in Column 5.  All of the nuclear generating plants owned and operated by Entergy’s Utility business are currently in Column 1.

Critical Accounting Estimates

The preparation of Entergy’s financial statements in conformity with GAAP requires management to apply appropriate accounting policies and to make estimates and judgments that can have a significant effect on reported financial position, results of operations, and cash flows.  Management has identified the following accounting estimates as critical because they are based on assumptions and measurements that involve a high degree of uncertainty, and the potential for future changes in these assumptions and measurements could produce estimates that would have a material effect on the presentation of Entergy’s financial position, results of operations, or cash flows.

Nuclear Decommissioning Costs

Certain of the Utility operating companies and System Energy own nuclear generation facilities.  Regulations require these Entergy subsidiaries to decommission the nuclear power plants after each facility is taken out of service, and cash is deposited in trust funds during the facilities’ operating lives in order to provide for this obligation.  Entergy conducts periodic decommissioning cost studies to estimate the costs that will be incurred to decommission the facilities.  The following key assumptions have a significant effect on these estimates.

•Timing - In projecting decommissioning costs, two assumptions must be made to estimate the timing of plant decommissioning.  First, the date of the plant’s retirement must be estimated for those plants that do not have an announced shutdown date.  The estimate may include assumptions regarding the possibility that the plant may have an operating life shorter than the operating license expiration.  Second, an assumption must be made regarding whether all decommissioning activity will proceed immediately upon plant retirement, or whether the plant will
